<p><P>PROBLEM TO BE SOLVED: To improve quality of a cast slab in a method for controlling impressing strength at the casting end. <P>SOLUTION: In a deceleration region d for decelerating the casting speed after a stationary region s in which the casting speed is constant, a ratio X<SB POS="POST">t</SB>of the impressing strength B<SB POS="POST">d</SB>in the deceleration region d with respect to the impressing strength B<SB POS="POST">s</SB>in the stationary region s is controlled to satisfy [(20/T)×t+100]≤X<SB POS="POST">t</SB>≤180, wherein T represents the time [min.] of the deceleration region d from the start of deceleration to the end of casting, and t represents the elapsed time [min.] from the start of deceleration. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
