In an embodiment, the disclosure relates to the manufacture of glass sheets in a fusion draw machine (FDM). More specifically, the disclosure expands the known methods and apparatus for producing laminated glass sheets (see U.S. Patent 4,214,886).

In an embodiment, the disclosed apparatus and disclosed use and manufacture The method provides one or more advantageous features or aspects including, for example, as discussed below. Any feature or aspect described in the scope of any patent application is generally applicable to all aspects of the invention. Any one or more of the features or aspects described in any one of the claims may be combined or interchanged with any other described feature or aspect of any other patent application.

In low temperature applications, such as below 1000 °F, rigidity and stability can be obtained using conventionally extensible mechanical fasteners. However, materials that can withstand extremely high temperature operations are generally fragile and therefore unsuitable for use as conventional fasteners. The disclosed refractory liner allows for maximum material loading in terms of shear and endurance in its engagement. In addition, the component parts of the disclosed gasket are assembled by gravity and by a combination of component geometries.

The refractory material maintains its strength at high temperatures. ASTM C71 defines fire resistance as "non-metallic materials with those chemical and physical properties that make them suitable for use in environments exposed to temperatures above 1,000 °F (811K; 538 °C) or as exposure to 1,000 °F (811K; 538 °C) System components of the above environment". For example, aluminum oxide (alumina), niobium oxide (alumina), magnesium oxide (magnesia), and similar materials (such as carbide), or a combination thereof, can be used as a liner construction. material. Any of the elements of the interlocking structure may be made of a suitable refractory material, for example, a material that can withstand the high temperature environment within the melt drawing apparatus during operation. Most extremely high temperature materials are fragile, such as tantalum carbide (for example, gold or sandstone). The application of these materials for structural struts is modified to their particular material properties. The disclosed interlocking structure minimizes the tensile load in the strut and disperses the remaining shear load over a larger pad surface area.

In an embodiment, the liner is located between (wrap around) the wrap housing and the chamber, the chamber being occupied by the first upper and lower isolation tubes in the melt drawing apparatus. In an embodiment, the liner may additionally include an outer structural strut between the liner and the wrap housing. In an embodiment, additional outer structural struts may be used to supplement the stability achieved by the structural struts with selective adhesion bonding between the top panel and the first and second wall portions. This may take the form of, for example, a sillimanite block embedded in a refractory brick surrounding the liner. The sillimanite is an alumino-silicate mineral of the chemical formula Al ₂ SiO ₅ .

In an embodiment, the control of the melt treatment (or specifically the lamination melt treatment) generally requires that the disclosed liner structure be independently or non-independently subjected to one or more specified movements when attached to the wrap. Spatial orientation or movement. In order to conform to the orientation and movement of the wrap, liner, or both, the pad structure preferably has sufficient rigidity and stability to effect an angular adjustment of the wobble or movement within the wrap, or as a wrap Part of the object.

In an embodiment, the disclosure provides a refractory liner comprising: an interlocking structure comprising: a top panel; a first wall portion and a second wall portion; a first pillar having the first pillar a first interlocking member and a second interlocking member, the first interlocking member is located on a first shaft, and the second interlocking member is located on a second axis orthogonal to the first shaft, The first interlocking member is interlocked with a first complementary interlocking member on the first side wall, and the second interlocking member is interlocked with a first complementary interlocking member on the top plate; and a second pillar having a first interlocking member and a second interlocking member, the first interlocking member being located on a first shaft, and the second interlocking member being located orthogonal to the first a first interlocking member interlocks with a first complementary interlocking member on the second side wall, and the second interlocking member and a second complementary interlocking member on the top plate Interlocking.

In an embodiment, the first interlocking member, the second interlocking member, the first complementary interlocking member, and the second complementary interlocking member are independently selected from a blink, a cymbal, or an equal structure. Or a combination thereof, or a similar interlocking connection or similar interlocking connector.

In an embodiment, the disclosure provides a refractory liner article for use in a melt drawing apparatus, also known as a "dog house", the refractory liner article comprising: an interlock Structure, the interlocking structure comprises: a top plate, that is, a cover tile; a first wall portion and a second wall portion, that is, the side walls; a first pillar, the first pillar has a first And a second turn, the first turn is located on a first axis, such as an x-axis perpendicular to a plane of the first wall portion, and the second turn is located at a second axis orthogonal to the first axis Up, for example, a y-axis perpendicular to a plane of the top plate, the first cymbal interlocking with a first mortise on the first side wall, and the second cymbal interlocking with a first mortise on the top plate And a second pillar having a first weir and a second weir, the first weir being on a first axis, and the second weir being located in a second orthogonal to the first axis a first 榫 on the shaft and a first 榫 on the second side wall The eyes are interlocked and the second jaw interlocks with a second eye on the top panel.

The refractory liner may further comprise a selective adhesive sealant applied between the top plate and each of the first wall portion and the second wall portion, wherein the adhesive sealant applies the top plate The lifting and lowering sliding motions along the y-axis are fixed (i.e., fixed, restricted, or degrees of freedom are eliminated).

The refractory lining may further include a second refractory pad portion, wherein the first refractory lining forms a top half and the second refractory lining forms a bottom half, and the halves are oriented to form A chamber to accommodate at least one molten draw isolation tube. In use, the bonded refractory liner is oriented to be substantially upright such that one refractory liner acts as the top and another similar refractory liner acts as the bottom below the top refractory liner. The bottom refractory liner differs from the top refractory liner in that, for example, the top liner has a substantially "closed" or no significant void or gap, and the bottom liner has a substantially "open" bottom panel, for example, a bottom panel. There are gaps to allow the build-up or similar sheets of glass formed in the chamber to pass out of the chamber and advance toward additional selective processing, such as cooling, stretching, cutting, and similar post-pull or post-layer unit operations.

The interlocking structure of the component part of the refractory pad may comprise a sliding fit component. The sliding fit between the components, that is, the individual pairs of the struts on the struts are paired with the mortises on the top and wall sections (ie, the ridges on each struts and the mortises on each side wall) A vertical dovetail joint is created that limits the axial, lateral, and rotational freedom of the interlocking structure with the cushion article.

The interlocking structure can have, for example, at least two limited or fixed (also That is, the fixed, restricted, or eliminated degrees of freedom include, for example, the side-to-side sliding motion along the x-axis, and the rotation about the z-axis.

The interlocking structural element can be made, for example, of any suitable refractory material.

The interlocking structure can have an upper portion and a lower portion, or a half portion, which can be separated by a gap. This gap provides directional control of the wrap with the two halves. The interlocking structure can have an open or partially open end to allow for the delivery of a molten glass source, and the interlocking structure can have an open bottom to allow for the delivery of the resulting molten glass product.

The interlocking structural element can have, for example, a height to width aspect ratio (see Figure 5A, associated vertical to horizontal dimensions) of, for example, from 10:1 to 1:10, 7:1 to 1:7, 5:1 To 1:5, 2:1 to 1:2, including intermediate values and ranges.

In an embodiment, the pad may be higher than the width of the base or the width of the top plate, that is, a higher aspect ratio. The higher aspect ratio of the structure combined with the selectively adjustable movement or movement of the wrap melt draw apparatus may require substantial structural integrity of the liner structure. Thus, the disclosed interlocking structure provides superior mechanical strength and rigidity to the refractory liner. The interlocking structure may also have, for example, a height to length aspect ratio (see Figure 5B, associated vertical versus horizontal dimensions) such as from 1:10, 1:7, 1:5, 1:2, 1:1 , and similar ratios, including intermediate values and ranges.

In an embodiment, if the liner has a long length dimension, more than one top panel (e.g., 2 to 10 or more) may be required for the liner to form a fully or substantially closed top. Similarly, if the pad has a long For length dimensions, more than one side panel (e.g., 2 to 10 or more) may be required on each side wall to form a continuous sidewall of the liner. A plurality of top panels or a plurality of side wall panels may be integrated into the liner structure and joined together using, for example, interlocking engagement, such as using the end slots shown in FIG.

The disclosed refractory lining is stable for tilting motion, scrolling motion, sliding motion, or a combination thereof, and similar transfer motion, rotational motion, or a combination of transfer motion and rotational motion. The high motion stability of the refractory lining can be applied to a free standing pad structure or a pad structure when fastened to the interior of the wrap.

The refractory liner may be free of separate mechanical fasteners when constructing a free standing liner structure. In an embodiment, the selective adhesive provides adhesion between the mating components (including the sidewalls of the cover tile relative to the liner) to provide additional structural rigidity to prevent minor slippage of the cover panel or cover tile relative to the sidewalls. . Additionally, a selective adhesive can provide a seal between the walls of the structure to prevent penetration of the foreign material, which can increase the sliding or instability of the bonding interface and can jeopardize the structural integrity of the liner.

The refractory lining structure can further include a surface protrusion on the side edges of the top panel, the surface protrusion and a through hole on a top edge of each of the first and second wall portions Interlocking to form, for example, a tongue and groove splicing joint.

The refractory liner may further include an adhesive applied between the surface protrusions of the top plate and each of the through holes on the first wall portion and the second wall portion to form the top plate and a seal between the contact areas of the walls or the contact contacts to freely rise and fall the top plate along the y-axis Fixed.

In an embodiment, the liner has a structural corner strut element having a vertical dovetail joint. In an embodiment, the wall portions may have selective surface protrusions that may additionally secure the structural element in three-dimensional space and resist any forces acting on the joint. In the embodiment, it is preferable that the contour is a "puzzle piece"-like dovetail joint, and if an external force or an unstable force is applied, the joints are pulled together, effectively making them tighter. .

The refractory liner may further comprise a second refractory liner in combination with the refractory liner, wherein the bonded liners (above and below) form a melt draw process a chamber, and the bonded gasket provides a thermal barrier that prevents heat loss, and the bonded gasket provides a protective barrier that protects the glass flow from the melt draw from External contamination, such as contamination from the heater element, in which the heater element maintains the glass in a liquid state.

Referring to the drawings, Figure 1 shows an example corner post (100) component of the disclosed pad structure. The corner post (100) component has two vertical turns (110, 120), and the turns (110, 120) are respectively joined. A complementary mortise is formed on the top or cover tile and one of the side walls of the two side walls of the structure to form a dovetail joint, respectively. These dovetail joints can limit the axial, lateral, and rotational freedom of the liner to impart better structural stability. In an embodiment, the struts preferably have symmetric ridges, mortises (110, 120) such that the first struts are interchangeable with the second struts. In other words, an exemplary angular struts (100) design with mirror symmetry can be used for each of the desired corner struts in the disclosed structure.

In an embodiment, the ridges of the corner struts may be replaced by mortises, and the mortises of the top and side walls may be replaced by enamel. In an embodiment, the ridges of the corner struts may be replaced by a combination of ridges and mortises, and the mortises of the top and side walls may be replaced by a combination of suitable ridges and mortises. The corner struts (100) can form two vertical dovetail joints by joining the top or cover tiles and the side walls of the structure, respectively. These joints can limit axial, lateral, and rotational freedom. Once the structure is assembled, these degrees of freedom are limited and the pad structure is stabilized.

Figures 2A through 2C show an exemplary sequence or sequence of assembly of the disclosed structures. Figure 2A shows a first step of assembly in which the jaws (e.g., 110 or 120) of the first leg (100) are slidably engaged with the mortise of the first wall portion (210). Thereafter, the jaws of the second leg (102) (eg, the side (110) or the vertical (120)) are slidably engaged with the mortise of the second wall portion (220). Figure 2B shows a second step of assembly in which the mortise of the top plate (205) is, for example, slidably joined downwardly to the remaining available top or vertical mortise of the first and second struts (100, 102). Figure 2C shows a third step of assembly in which the slidably joined top plate (205) and the first and second wall portions can have selective protrusions (235) and through holes (230 in Figure 2B). In combination, the protrusions (235) can be additionally joined and joined with the through holes (230) using, for example, a selective adhesive, solder, or similar fastener to complete assembly of the pad structure (200). The pad structure (200) is preferably assembled as illustrated and in a specified sequence such that all of the components are properly and securely joined. In an embodiment, a plurality or a plurality of successively aligned plate and wall elements are contemplated and the plates can be easily assembled with the wall elements to form the disclosed structure.

In an embodiment, the order in which the pads are assembled is important for better structural integrity. The structure can be assembled in a prescribed order for all components to properly engage. The only degree of freedom left in the assembled structure is the vertical movement of the top cover. The top cover cannot move vertically during normal operation and positioning in the wrapper housing. However, vertical freedom is also limited once a selective adhesive is applied to the cover tile-wall joint.

Figures 3A through 3C schematically illustrate the progression of the freedom of the top plate (205) and side walls (210) of the pad structure (200) by implementing the corner posts (100, 102). Figure 3A shows an unjoined and unconstrained structure having traverse degrees of freedom in each of the x, y, and z axes, and at least around the z axis Rotational degrees of freedom. Figure 3B shows the structure of the joint of the side wall (210) and the through hole in the top plate (205) with limited structure (but no selective adhesive), the structure being on the wall (210) and the top plate (205) Between, and the structure has a traverse freedom of only in the y and z axes. The degree of freedom of rotation about the z-axis is still maintained. Fig. 3C shows the structure in which the corner post is added to the joint between the wall (210) and the top plate (205) of Fig. 3B and the through hole (i.e., the tongue and groove joint (420) is joined) and the structure is limited. . The traverse freedom in the x and z axes and the rotation about the z axis disappear, and are now fixed by the interaction of the ridges of the struts with the mortises (410, 415) of the top and side walls. Only the traverse freedom along the y-axis remains. The addition of a selective adhesive or similar fixative to the tongue and groove splicing (420) fixes the remaining traverse freedom along the y-axis.

In an embodiment, the disclosure provides a structural component that provides stable resistance by limiting the limited degrees of freedom at the corner joints of the assembly. Fire pad (also known as: dog house) structure. The disclosed angular joints and additional struts limit the degree of freedom and strengthen the structure.

Figure 4 shows a perspective side view of the assembled pad structure of Figure 2C, and additionally illustrates preferred mechanical stability. The ridges (110, 120) of the struts (100) engage the mortises (410, 415) of the top plate (205) and the side walls (210) and create an interlocking dovetail joint. The engagement of the protrusions (230) of the top plate with the through holes (235) of the side walls creates a tongue and groove splicing engagement (420). The tongue and groove splicing engagement eliminates side to side freedom. The applied adhesive provides additional stability and durability to the tongue and groove joint (420) and liner structure, and prevents heat loss from the melt draw process and prevents external material from penetrating into the melt draw process. . Alternatives to tongue and groove splicing engagement may include, for example, slot engagement, insertion engagement, or similar engagement designs, but these may provide lower stability than tongue and groove engagement and adhesive combinations.

The combination of the corner struts and the selective adhesive joint limits the freedom of longitudinal and rotational. In addition, the weight of the top cover, the combination of the selective adhesive, and the range of motion of the wrapping device limit the remaining degrees of freedom. This produces a rigid, stable doghouse structure.

Figure 5A shows an exemplary schematic view of a cross-sectional end view of a melt drawing apparatus (500) having a wrap structure (502) that contains a double layer or a layer of melting The structure (510) is withdrawn and the exposed liner (200). The apparatus (500) includes a wrap structure (502) having a first upper portion (504) and a second lower portion (506), the first upper portion (504) having a top portion and at least two long sides portions, and The second lower portion (506) has a bottom portion and at least two long side portions. Lower part (506) The bottom portion includes an opening (508) for the exit of the glass or laminate product. The wrap structure (502) defines and provides a chamber that is occupied by a melt drawing device (510) having one or more isolation tubes (showing a first upper tube and a lower tube). The wrap (502) provides a thermally isolated chamber that houses the isolation tube. The wrap (502) may additionally include or comprise one or more heat source elements (512), such as a heating rod, microwave, or similar heating element. The wrap (502) additionally includes and comprises a refractory liner (200), for example made of a radiant heat resistant material such as tantalum carbide, and the refractory liner (200) is located in the wrap (502) The resulting enclosure is between the chamber for the melt drawing device (510). The refractory liner (200) may include an upper portion (215) and a lower portion (220), the upper portion (215) having a top plate (205) and a side wall (210), and the lower portion (220) having a side wall (225) with an open bottom or partially closed The bottom (not shown). The gasket structure protects the liquid glass stream from contamination that may come from the heat source element (512) and can stabilize heating uniformity within the chamber. The upper portion (504; 215) and the lower portion (506; 225) of the wrap (502) and the liner (200) may be separated or separated by a sealing region (550). The sealed area (550) is described in detail in the above-referenced patent application USSN 61/678,218. The sealing region may comprise, for example, one or more selective seals having different or redundant functions, such as: a radiation seal made of a material that is resistant to radiant heat, such as maintaining a large amount of radiant heat in the lumen Indoor refractory bricks; heat seals made of elastic refractory materials, such as Safil cloth, which further reduce heat loss; and convective seals made of elastomeric materials, such as rubber or silicone rubber, which reduce convection losses and maintain An extra amount of heat is inside the lumen. The heat seal can be attached, for example, to both the upper portion (504) and the lower portion (506) of the wrap. Alternatively, the heat seal can be attached, for example, only to the upper portion (504) of the wrap and to the lower portion (506) of the wrap. The sealing area (550) is an important aspect of the better results provided by the melting apparatus with the disclosed liner. This region may: maintain a desired similar temperature distribution within the upper and lower portions of the wrap; and allow the upper and lower portions of the wrap to be spatially independent. Alternatively or additionally, the position of the upper cladding tube spatially related to the lower core tube can be spatially independently adjusted to vary or control the thickness ratio of the cladding relative to the core in the resulting laminated product. In an embodiment, the upper and lower portions of the wrap are spatially independently adjustable to allow the interstitial region between the upper and lower isolation tubes to be adjusted to change the wrapper relative to the laminated product in the drawn product The thickness ratio of the core glass. In an embodiment, the upper cladding tube or upper pad portion (215) may be secured within the upper portion (504) of the wrap, and the lower core tube or lower pad portion (220) may be secured to the lower portion of the wrap (506) Inside, the spatial adjustment of the upper portion of the wrap causes the accompanying spatial adjustment of the upper wrap. Each seal allows for independent adjustment of the spatial orientation of the upper and lower portions of the wrap, and thus allows for independent adjustment of the relative orientation of the pad portion to the isopipe, and ultimately controls the wrap and resulting from the disclosed glass melting apparatus The relative thickness and uniformity of the core flow.

Figure 5B shows a schematic cross-sectional side view of the disclosed liner (200) and melt draw apparatus (500) shown in Figure 5A.
