Field of the Invention The present invention has a casting area which is formed in a funnel-like shape in a casting direction in a size of a strand to be cast and a back wall provided with a slit through which a liquid cooling medium flows.

でなければならない。BACKGROUND OF THE INVENTION The problem with molds is to form the strands and to remove from the melt the heat required for the growth of strand solidified shells. At the mold exit, the solidified strand shell must be thick so that it can withstand thermal and mechanical loads and to ensure that the strand does not crack.

が保証されるように行われる。According to the prior art, the cooling channels and the slits are oriented vertically, ie in the casting direction, in order to reach as uniform a heat extraction as possible over the entire width of the plate. The arrangement of the holes or slits and their dimensions is determined in such a way as to ensure as uniform a heat extraction as possible over the entire plate surface.

変形しないように、十分な大いさでなければならない。[0005] Further, when constructing the mold plate, the provision of threads and thread inserts for the screws fixing the mold plate to the water collecting box is also considered. The number of anchoring points must be large enough so that the template plate does not deform beyond its allowable dimensions by carrying thermal loads during the casting process.
【０００６】垂直方向に指向しているスリットを備えて

形成を招く鋳型板の局所的な変形を誘起する。[0008] Despite the large thermal load in contact with the molten metal, it is easy to eliminate the formation of cracks on the working surface of the mold plate when the structurally correct construction and material selection are made. It is possible. Moreover, the use of the mold plate over a long period of time can be caused, for example, by the mechanical movement of the mold plate, which occurs during the entry and exit of cold strands and when narrow-side movements occur during the casting operation. It induces local deformation of the mold plate which causes damage to the working surface of the mold plate such as wear and scratches and formation of a gap with the narrow side.

It depends on the number of times.

った後スラブに分割され、炉を経て直接圧延工程に供給
可能な、可能な限り肉薄のストランドを鋳造しようと言
う望みに帰される。The idea of a funnel-shaped casting area is attributed to the desire to cast as thin a strand as possible, which can be split into slabs after leaving the casting machine and fed directly through a furnace to the rolling process.
【００１１】鋳込み領域の寸法は、本質的に鋳造される

倍にもなる長い全寿命が伸びる。In operation of a number of continuous casting plants comprising different perforated template plates and slit-formed template plates made of different copper alloys, forming funnel-shaped casting regions having different dimensions. After a relatively small number of castings of only 100 at the level of the molten metal,
It was confirmed that cracks occurred in the mold plate. Therefore, when the rework is performed three to four times on average, a long total service life, which is about 1000 times as much as that of the molten metal, is increased as compared with a mold plate having a flat working surface.

が明らかになった。The cracks are the result of mold material fatigue as a result of plastic alternation. Measurements by thermal elements and statistical evaluation of the tendency to crack formation in the mold plate show that the cracks are always present in the parallel part of the hopper, the transition area, not due to above average local thermal load It became clear.

The smaller the number of anchoring points, the more unevenly distributed the tension and elongation over the width. The tension and elongation are increased and localized in the area of one of the outer rows of the fixation points on each side, depending on the arrangement of the fixation points. Therefore, the basic premise for crack avoidance of a uniform distribution of tension and elongation over the width of the template plate is a sufficiently large number of fixing points.

The occurrence of cracks in the mold plate, which is attributed to the presence of a bend that contributes to the formation of a funnel-like casting area, is aided by the additional extension in the transition zone, a parallel part of the hopper.

S2, S3, S4, S5 and S6 are fixed to the water collecting box 2. The width of the strand is determined by the position of the narrow side 3. The position of the cooling holes is determined by the working thickness d1, i.e. by the distance to the working surface and by the distance d2 to the back wall.

れ、作業面の始めに据込まれた領域が附加的に延びる。For example, during the initial working phase of casting or as a result of the change of the molten metal level, the heating of the mold plate 1 by the heat flow q leads to a change in the length in the three directions on the narrow side as a result of the extension of the mold plate material, This change in length is unimpeded when the work surface is flat, so that additional tension and elongation are induced in the mold plate. In contrast, in molds having a funnel-shaped casting area having a width B, the working surface of the mold plate is additionally installed. This is because this area is the fixing screw S1,
This is because S2, S3, S4, S5 and S6 cannot be extended freely because the mold plate is fixed at the fixed points at positions X1, X2, X3, X4, X5 and X6. For example, when cooling the mold plate after the end of the casting process,
The contraction causes a length change in the opposite direction, which additionally extends the area upset at the beginning of the work surface.

It depends on the working thickness d1 between the holes, the mold plate thickness d2 between the coolant flow path and the back wall, and the width B of the curved area.

することが分かった。A mold having a funnel-shaped casting area,
Calculations for the perforated and slit-formed template plates used in the practice of casting show that the additional alternating extension can be plasticized together with the extension resulting from general thermal loading. It has been found that a value is reached which leads to a very rapid fatigue of the template sheet material due to the occurrence of a typical alternating deformation.

鋳型板断面の剛性を増大させることが必要である。In order to reduce the load of the curved mold plate to a safe degree with respect to cracking by a structural configuration, in a simple case, the mold plate thickness d2 between the coolant flow path and the back wall is required. By increasing the degree to
It is necessary to increase the rigidity of the cross section of the mold plate.

板剛性の向上は鋳型板幅全体にわたる張力と延びの均一
な分布を誘起する。Since there is no temperature gradient behind the coolant flow channel, the rigidity of the mold plate is increased by increasing the thickness of the mold plate between the back wall and the coolant flow channel when the heat load is equal. The enhancement induces a uniform distribution of tension and elongation across the width of the template.

検出された温度が総じてより低く降下するからである。The extension of the mold plate in the horizontal direction, which favors the occurrence of cracks on the work surface, is reduced. This is because the template plate is not heated significantly behind the cooling holes compared to the area between the working surface and the cooling holes, and the temperature detected over the entire mold section drops generally lower.

A perforated mold plate having a sufficiently large wall thickness d2 between the back walls fixed to the water collecting box by Sn is used to reduce the working surface to a certain heat load qmax.

鋳型板の構造を提供することである。The problem underlying the present invention is that it has a slit cooled by water on the back wall side and the work surface is cracked up to a certain heat load qmax. A funnel-shaped casting area that stays absent and, in excess of this heat load, has cracks distributed evenly over the width of the template plate, thus achieving a service life comparable to a template plate with flat walls. The purpose of the present invention is to provide a mold plate structure of a mold having:

The slit moves the transition line 30 degrees from the horizontal plane.
The problem is solved by the fact that it does not deviate more than °.

らである。The present invention is based on the recognition that the cross section of the mold plate must be as large as possible in order to avoid the formation of cracks on the working surface at a given working thickness. This is because the relatively high rigidity and relatively little horizontal extension of the template plate induces a uniform distribution of tension and extension over the entire width of the template plate.
