JPS5758953A - Block type casting for continuous casting - Google Patents

Abstract

PURPOSE: To obtain a mold for continuous casting which can change the cooling capacity in its longitudinal direction in conformity with the distribution of heat flow flux by disposing concentrically an outside cylinder and an inside cylinder having multiple cooling water flow passages at equal intervals via partition walls on the inside or outside circumferential wall in a longitudinal direction over the entire length, and forming the contact parts of the outside cylinder and the inside cylinder to one body by diffusion welding.

CONSTITUTION: An outside cylinder 2 and an inside cylinder 1 having multiple cooling water flow passages 4 worked to arbitrary shapes at every equal interval via partition walls 2a over the entire circumference of the inside or outside circumferential walls manufactured respectively separately in a longitudinal direction over the entire length are concentrically disposed. The contact parts of the outside cylinder 2 and the inside cylinder 1 are metallurgically solid phase bound by diffusion welding, whereby both cylinders are welded to one body. In this way, the cooling water flow passages 4 of arbitrary shapes are formed in the longitudinal direction of the inside circumferential side surface of the cylinder 2 or the outside circumferential side surface of the cylinder 1, and the cooling water conforming to the heat flow flux distribution of the molten steel in the cylinder 1 is flowed to the passages 4.
