PURPOSE:To improve the seal of belt type continuous caster by arranging a belt mold pushing device between an edge part of belt mold and a short side fixed mold and forming the belt mold as been possible to push to a cooling pad by the pushing device. CONSTITUTION:Molten steel is poured at the upper part of belt mold 1 drived by a guide roller 4 and a width of cast sheet 5 is decided by the short side fixed mold 2, to cool by bringing the cooling pad 3 having suitable carvature into contact with the back face of mold 1. Then, the mold 1 is pushed to the pad 3 by the belt mold pushing device 6 arranged at the reversing side of the cooling pad 3 to the belt mold 1. Cooling agent supplied from plural holes in the cooling pad 3 is collected at the part between the pad 3 and mold 1 to become to high pressure, and so the gap between the molds 1, 2 is sealed by floating the mold 1. In this way, the seal of belt type continuous caster is improved. |
