Twin belt type casting machine

A twin belt type continuous casting machine having a pair of belts and a pair of edge dams disposed between said pair of belts to define a metal pool so as to produce a thin slab by allowing a molten metal poured into said metal pool to be cooled and solidified, said edge dams being disposed between said belts in such a manner as to be movable in the transverse direction of said belts, said twin belt type continuous casting machine comprising:

• a plurality of cooling/heating chambers disposed respectively such as to be adjacent to respective rear surfaces of said pair of belts and to be in the vicinity of side end surfaces of said belts in a transverse direction of said belts and partitioned in said transverse direction;
• a cooling box disposed in the vicinity of a central portion in said transverse direction of said belts;
• a plurality of pressing means which are capable of pressing said rear surfaces of said belts;
• a fluid supplying piston header in which one portion of an internal space thereof divided into two by a piston, is connected to a cooling water supplying source, and the other portion thereof is connected to a heating medium supplying source for heating side end surfaces of said belts, a plurality of branch channels respectively communicating with said plurality of cooling/heating chambers in the axial direction being provided in said internal space;
• a discharge piston header provided with a plurality of discharge-side branch channels respectively communicating with said plurality of cooling/heating chambers;
• and
• a control device for selectively actuating at least one of said plurality of pressing means in such a manner as to press said belts against said edge dams moved.
