    摘要: In a type of continuous casting of steel in which a straight mold is employed and a cast strand is guided while being bent, molten steel is continuously teemed into said straight mold; an unsolidified cast strand with a solidified shell formed on it is guided substantially vertically downward within a range from 3 to 7m from the meniscus of molten steel in said straight mold; then, said unsolidified cast strand being in the vertical position is guided within a range from 1 to 4m while being bent at multiple points by gradually decreasing the radius of curvature of said cast strand for each of successively arranged pairs of bending rollers; then the solidification of said unsolidified cast strand thus bent at multiple points is completed before a spot-straightening point while further guiding said cast strand along a constant curvature, the track length of said constant curvature guide being within a range from 35 to 85% of the length from said meniscus of molten steel in said straight mold up to said spot-straightening point; then, said cast strand is reduced, near its solidification completing point, at a draft of 0.1 to 2.0% per pair of reduction rolls; and then, said reduced cast strand is straightened in a substantially horizontal direction at a single point at said spot-straightening point; whereby a continuously cast strand free from or with remarkably decreased inner and outer defects is obtained.

    摘要: In a mold apparatus for an endless track type continuous casting machine of the type in which a plurality of cooling blocks are interconnected with each other in the form of an endless chain to assemble a cooling block chain which can define a straight wall; a pair of said cooling block chains are disposed such that the straight wall thereof define a mold; and the cooling block chains are moved in synchronism with the casting speed or rate, a plurality of cooling holes are extended through each cooling block in the direction perpendicular to the direction of the movement thereof and in parallel with the straight wall section thereof; one or more cooling water pipes are disposed along one side surface of said straight wall section of each cooling block chain and are provided with a plurality of nozzles in line with the cooling holes of the cooling blocks so that the cooling water is injected through the nozzles to their corresponding cooling holes of the cooling blocks which are moving, thereby cooling the cooling blocks in contact with a casting with the cooling water. Therefore, the cooling blocks can be cooled very effectively; a satisfactory shell growth rate can be attained; and break-out or the like can be avoided even when the cooling block chains are stopped in case of emergency.
