PURPOSE:To prevent the development of strain without arranging a device for correcting the strain on belt surface by separating shifting short side from a cast slab at upstream side from center of the downstream side roll is belt type continuous casting machine. CONSTITUTION:While rotating the casting belt 5 and the shifting short side 11 to the cast slab drawing direction, molten metal is poured into a mold 3 through a flat nozzle 1. Further, the shifting short side 11 is separated from the cast slab S at the upstream side from the center of the downstream side roll 8. Then, by friction force between the casting belt 5 surface and the side face of the shifting short side 11, both side edge parts of the casting belt 5 is stretched to outside along the belt surface. As a result, the belt surface deformed with heat strain is stretched to both sides and the belt surface becomes flat. Therefore, the special device for correcting the strain on the belt surface is not necessary to arrange. |
