A plate brick storage unit 3 and a movable plate brick storage unit 4 overlapping the plate brick storage unit 3 are provided, and plate bricks 5 and 6 are fixed and stored in these storage units 3 and 4 by bolts 7 and 8 and are movable. The plate brick storage section 4 slides by the operation of the cylinder 9 supported outside the apparatus main body 2, and changes the alignment position of the nozzle holes 10, 11 formed in the center of the plate bricks 5, 6 to change the molten metal. are Ninasa to control runoff. Generally, the apparatus main body 2 is continuously used in a hot state, and the plate bricks 5 and 6 are exchanged for several ladles.

る。However, in the case of the above two-face restraint, due to the compressive force of the plate bricks 5 and 6 in the longitudinal direction, an operating part (a molten steel flow rate is controlled at a central part indicated by a in FIG. 6). The part that includes the nozzle holes 10 and 11 and that may come into contact with the molten steel) is in the width direction (the direction of the arrow).
The cracks tend to spread in the peripheral portions of the nozzle holes 10 and 11 and the operating part including the nozzle holes 10 and 11, and once the cracks are formed, the cracks are easily expanded and the plate bricks 5 and 6 are damaged. There is a problem of shortening the service life.

時に取外し難くなるという問題がある。In the case of the four-plane constraint, the plate bricks 5 and 6 are constrained by the inclined surfaces at the four corners. Therefore, as in the case of the two-plane constraint, the forces bulging laterally are concentrated on the movable part. However, in order to suppress the generation of cracks around the nozzle holes 10 and 11, the effect cannot be expected unless the constraint angle θ is reduced. However, when the constraint angle θ is reduced, the nozzle bricks 10, 10 in the longitudinal direction of the plate bricks 5, 6 due to variations in the length, width, length and angle of the constraint surface (inclined surface) in the manufacture of the plate bricks 5, 6. Not only is the position shift of 11 easy to occur,
There is a problem that biting occurs on the fixed side, making it difficult to remove the plate bricks 5 and 6 during replacement.

目的としてなされたものである。In view of the above, the present invention does not swell laterally around the nozzle hole at the time of restraint, thereby preventing the occurrence of cracks, and at the same time, the nozzle hole is less likely to be displaced and has a fixed side. An object of the present invention is to provide a plate brick of a slide valve for controlling a flow rate of a molten metal, which does not cause biting in the plate.
