CONTINUOUS CASTING FACILITY

摘要

Disclosed is a continuous casting facility equipped with a plurality of supporting rollers arranged oppositely on the opposite sides of the passage of cast piece, wherein each supporting roller has a plurality of split rollers arranged along the width direction of the cast piece, and for each supporting roller arranged at a position on the passage where the central solid-phase rate of the cast piece is 0.2-1.0 during continuous casting process, the interval A and the distance B satisfy the following relations; A=0.001×B2-1.5×B+735 and 400=B<680, when the interval of the split rollers adjoining in the width direction of the cast piece in the supporting rollers is defined as the interval A (mm), and the distance from a supporting roller adjacent to the above-mentioned supporting roller on the downstream side in the casting direction to a supporting roller adjacent to the above-mentioned supporting roller on the upstream side in the casting direction is defined as the distance B (mm).
