[Industrial applications]

  INDUSTRIAL APPLICABILITY The present invention is applicable to a metal molten metal storage tank such as a metal molten metal filtration tank or a metal molten metal stirring tank. It relates to the upper brick structure of curb bricks.

[0002]

[Prior art]

  Metal sheets and foils are produced by casting molten metal into an ingot and rolling it. Manufactured. However, metal oxides contained in molten metal and minute fragments of refractories If the solid impurities in the ingot are mixed into the ingot as they are, they are rolled and rolled into thin plates or foils. Pinholes and surface defects may occur during the manufacturing process. To prevent this , Ceramic aggregate particles are bound by an inorganic binder to create innumerable fine particles between the aggregate particles. Use a tubular filter with a structure with continuous pores, and keep it by the side plate. Hold it and assemble it into a cartridge. A method of removing solid impurities is adopted.

[0003]   Such a molten metal filtration device is generally equipped with a filter cartridge inside. It has a molten metal filtration tank and a tapping room that contains the filtered molten metal. The partition that forms the passage for the molten metal between the tank and the tap room is a filter called a frame brick. It is composed of a holding brick (hereinafter referred to as a frame brick in this specification). In both cases, the upper part is composed of bricks (hereinafter referred to as upper bricks).

[0004]

[Problems to be solved by the device]

  However, in the molten metal filtration device having such a structure, the molten metal is filtered. When over-operation is started, the upper part of the frame brick is heated by the heat of the molten metal sent into the tap room. The upper brick located on the side expands toward the filtration tank side, and this expansion force causes the filter cartridge to expand. The side plate of the lodge is not in close contact with the whole of the upper brick, leaving a slight gap. This state When the condition occurs, the problem that the molten metal from the filter leaks through the gap Occur.

[0005]

[Means for Solving the Problems]

  The present invention solves the above-mentioned problems in the related art, and the upper part located above the frame brick Providing an upper brick structure of frame bricks formed so that the bricks do not expand toward the filtration tank side The purpose is to   And, according to the present invention, the purpose is to put on the frame brick in the molten metal storage tank. In the partial brick structure, the brick located above the frame brick is divided and formed. In particular, each divided brick is formed in a shape that can be fitted together with other bricks. An upper brick structure, which is a feature, is provided.   Further, in the present invention, the divided bricks are embedded in the structure arranged on the outer peripheral side thereof. If a frame piece for fixing the divided brick is provided, the expansion of the divided brick Tension and movement are prevented, which is more preferable.

[0006]

[Action]

  In the upper brick structure of claim 1, the upper brick located above the frame brick is divided into several pieces. Since the divided bricks have a structure that can be fitted to each other, The thermal expansion of the upper brick due to is effectively prevented. Note that they can fit together here The structure means, for example, that the surface of the brick in contact with another brick is provided with a notch at a corner and The shape of the brick that fits with the surface of another brick (so-called "interlocking structure"), or the brick A convex portion is formed on the surface of the other brick that is in contact with the other brick, and the other brick is in contact with the brick. A concave portion that fits with the convex portion is formed on the surface to be formed (so-called dowel structure). Of.

[0007]   In the upper brick structure according to claim 2, each divided brick is arranged on the outer peripheral side thereof. Embedded in a structure such as a wall made of an amorphous fireproof heat insulating material (outer wall of the filtration tank) Since a frame piece that performs a so-called anchor-like action is provided, the thermal expansion of the divided bricks The tension, movement and displacement are more effectively prevented.

[0008]

【Example】   Hereinafter, the present invention will be further described with reference to the illustrated embodiments. It is not limited to the embodiment.   FIG. 1 is a portion showing an example of an upper brick structure located above the frame brick according to the present invention. FIG. 2 is a side view, and FIG. 2 is a partial sectional view showing an example of the structure of the molten metal filtration tank and the tapping room of the present invention. Is.   In FIG. 2, a plurality of tubular filters 10 are provided in the molten metal filtration tank A as side plates. A filter cartridge 12 that is supported and assembled by 11 is stored. B shows a tapping room, and the tapping room B has a tubular fill of the molten metal filtration tank A. A molten metal such as an aluminum melt filtered by the tar 10 is formed on the frame brick 13. It is accommodated through the closed passage 14.

[0009]   As shown in FIG. 1, the upper brick structure C located above the frame brick 13 has an upper brick structure C. The upper surface of the roof tile 15 has a notch 16 at the corner, and the notch 16 is different from that of another upper brick 17. The notches 18 on the lower surface and the interlocking structure are fitted together. Also, of the upper brick 17 The side surface has a dowel structure (FIG. 3) in the horizontal direction with the side surface of the upper brick 19 adjacent to the upper and lower sides. In the opposite direction, they are fitted to each other by a hooking structure (Fig. 1).   Further, as shown in FIGS. 1 and 3, the upper brick 17 is arranged on the outer peripheral side thereof. Embedded in a structure such as a wall 21 made of an amorphous fireproof heat insulating material and fixed There is provided a frame piece 20 for. In addition, as shown in FIG. The surroundings of the hot spring room B including 9 are covered with fireproof bricks 22, heat insulating boards 23, iron skins 24, etc. It is surrounded and insulated. Further, 25 is a ceramic paper.

[0010]   Since the upper brick structure in the present invention has the above-mentioned structure, The upper bricks 15 and 17 expand toward the molten metal filtration tank A side due to the heat of the molten metal that has been introduced. Is prevented, and as a result, the side wall 11 and the upper brick of the filter cartridge are prevented. There is no gap between the two and no leakage of molten metal.

[0011]

[Effect of device]

  As described above, according to the present invention, the following effects can be obtained.   The upper brick structure according to claim 1 is formed by dividing the upper brick into several pieces, and The split bricks have a structure that allows them to be fitted together, so that the thermal expansion of the upper brick due to the molten metal This is prevented, and as a result, there is an effect that leakage of the molten metal does not occur.   The upper brick structure according to claim 2 is arranged on the outer peripheral side of each of the divided bricks. Since a frame piece for embedding and fixing in the structure was provided, thermal expansion and movement of bricks -Displacement is more effectively prevented.
