Title: Twin belt type continuous casting device and its pouring nozzle
Inventor: HIRATA KOICHI
IPC: B22D11/06
Filed: 1992-11-04
Abstract: PURPOSE:To uniformly solidify molten steel and to suppress the generation of longitudinal cracks so that casting can be executed at a high speed by using a flat nozzle which is formed to a flat planar shape having a specific width and has having apertures on the transverse flanks and rear surface. CONSTITUTION:The mold is formed of a pair of endless belts facing each other and short side blocks which exist at both ends of these endless belts and are driven in synchronization with the endless belts, and therefore the slip with the mold and the overlaps of the solidified shell do not arise at both ends of the strip cast by such mold. The generation of defects is consequently obviated. The flat nozzle which is formed to the flat planar shape of >=30% and <=80% width of the nozzle with respect to the width of the mold and has the apertures 3, 4 on the transverse flanks and rear surface of the mold supplies the molten steel from the apertures on the short side, and therefore the pouring in the transverse direction is easily spread. The pouring nozzle is closed at its front end and is provided with the apertures therein, by which the fall of the meniscus between the nozzles is lessened and the deficient supply of the molten metal is prevented.
