As the congruence roll type continuous casting machine and congruence roll type continuous casting

摘要

PROBLEM TO BE SOLVED: To cool a cast slab remaining non-solidifying part in the center part just after coming out from the minimum gap in a twin rolls.;SOLUTION: The cast slab 113 came out from the minimum gap between the rolls 101,102, is in the non-solidifying state in the center part. Suction guides 221 are arranged along respective roll axial directions and cooling water sprays 211 are arranged with dispersion-state along the roll axial direction. The cooling water spray 211 is blown with the water against the cast slab 113 just after coming out from the minimum gap part to cool the cast slab. The suction guide 221 is sucked and removed to the water film etc., developed with the blown water and the cooling of the cast slab is surely performed so that the water blown from the cooling water spray 211 surely reaches the cast slab.;COPYRIGHT: (C)2007,JPO&INPIT
