Abstract

PURPOSE: To prevent transverse cracking flows and to make the improvement in yield and casting directly coupledto rolling possible by keeping the segregation rate of the segregation formed along oscillation marks at the flaw formation limit segregation rate or below.
CONSTITUTION: The segregation rate C of the segregation formed along oscillation marks is determined by the equationIand the equation II. Here, A: a proportional constant which is 13.0W20.0, R: a negative strip rate (%), (f): the number of oscillations of a mold (times/min), C0: flaw formation limit segragation rate, ≤10, t1: the oscillation period of the mold ×1/2, t2: the time when the oscillation speed of the mold exceeds the casting speed. The conditions of the equation III are satisfied, whereby the formation of the transverse flaws formed along the oscillation marks is prevented.
