In the mold for continuous casting which is used for the continuous casting equipment which produces the cast piece which cools the mold for continuous casting, which considers the change

摘要

PROBLEM TO BE SOLVED: To provide a mold for continuous casing under taking into consideration the variation of the casting radius of a cast slab caused by shrinkage and a continuous casting facility using the mold with which the cast slab having good quality can economically be manufactured.;SOLUTION: In the mold 10 for continuous casting used for the continuous casting facility 12 manufacturing the cast slab 11 cooling molten steel and solidified in a curving state from the molten steel, one of inside facing surfaces 16 in a mold body 15 is curved from an upper end toward a lower end, and the radius of curvature in the vertical direction of the curved inside facing surface 16 is continuously or intermittently reduced corresponding to the linear expansion amount and the temperature of the cast slab 11 from the upper end to the lower end of the curved inside faced surface 16. Further, the continuous casting facility 12 using the mold 10 for continuous casting is provided with plurality of guide rolls 19 gradually reducing in radii of curvatures of facing abutting carrying surfaces accompanied with reduction in radii of curvatures of the inside facing surfaces 16 at the downstream of the mold body 15.;COPYRIGHT: (C)2003,JPO
