PURPOSE:To suitably improve cooling capacity in accordance with casting width by displacing a block for pressing a short side mold from back side of a belt corresponding to displacement of the short side mold, suitably distributing heating medium and cooling medium and heating or cooling the belt. CONSTITUTION:Molten metal is poured into pouring basin part demarcated with one pair of the belts 4 and one pair of the short side mold 5, and while supporting the upper part of the belt 4 at near the surface 8 of the molten metal with disk type roll group 112 from the back side, the belt is cooled with the cooling medium from spouting pipe 111, and while supporting the lower part of the belt 4 with a cooling box 6, the belt is cooled, and the molten metal is efficiently cooled and solidified to draw out a metal strip 7 from lower part. In the above belt type continuous casting machine, the short side mold 5 is made to be possible to displace and the casting width is made changeable. Corresponding to the displacement of the short side mold 5, the pressing block 118 pressing this from the back side of the belt 4 is displaced with an actuator 117. Further, supply of the heating medium or the cooling medium is adjusted through the piston header 110 divided into two in the inner space thereof with a piston 110a to prevent deformation of the belt 4. |
