Filed: 1994-09-30
Abstract: PURPOSE: To reduce the rolling reduction force required for a squeezing by casting a cast slab strand having a projecting part in the one side of a front surface or a rear surface and rolling only the projecting part in the strand. CONSTITUTION: In order to reduce a center segregation in the cast slab strand 2a of a continuous casting, the squeezing is applied to the zone near the solidified completing point of the cast slab strand 2a during drawing out and shifting. The projecting part is formed on the surface of the cast slab strand 2a. When the width of the projecting part is (b) and the thickness of the cast slab strand 2a including the projecting part is (h0 ), the casting is executed so as to become b1 >=h and h1 >=h+d/2 to the size of the projecting part. Wherein, (a) is the width of the unsolidified part 2b, (d) is the thickness of the unsolidified part 2b and (h) is the thickness of the end parts of width of the cast slab strand 2a. The rolling reduction ratio δ is defined as δ>=d/2 so as to eliminate the center segregation.  At the time of squeezing, since there is no variation of a pass line, the equipment constitution is simplified.
