Abstract

PURPOSE:To prevent the generation of metal penetration and to make possible high-speed casting by constituting the long sides and short sides of a casting mold of synchronously driving belts and providing stationary corners each having a magnet in the contact parts of both belts. CONSTITUTION:The long sides and short sides of the casting mold in a belt type continuous casting machine for a slab are constituted of belts. The stationary corners 13 are provided in the contact parts between the long-side belts 2' and short sidebelts 12. Magnets 14 are disposed on the side of the stationary corners 13 in contact with both belts 2', 12. Both belts 2', 12 are thereby attracted to the corners 13, by which the generation of a space is prevented and the generation of the metal penetration is prevented. The belts 2' and the belts 12 are synchronously driven to eliminate the sliding with the slab and the high-speed continuous casting of the thick slab is made possible.
