PURPOSE:To produce safely a continuously cast slab at a high speed by using side endless belts which have water cooing devices and move at the same speed along stationary guides for the closed members on both sides of endless traveling belts in a belt type continuous casting machine for the slab. CONSTITUTION:A molten steel is poured into the space 1 constituted of a pair of the endless belts 2, 2 for casting and the side blocks 9 disposed to the end parts of both side faces thereof in the belt type continuous casting device. The molten steel is water-cooled to solidify by cooling water nozzles 7 by which the continuously cast slab is produced. The side blocks in such a case are constituted of the endless belts 12 which are made of the same material as the material of the belts 2 and are supported on the rear side by the stationary guides 13 having ribs 14 and form cooling water passages. The belts 12 move in the same direction at the same speed as the speed of the belt 2 and are water-cooled from the rear side as well and therefore the continuously cast slab 1 is safely cast continuously without the generation of a breakout accident by flash, etc. |
