Abstract

PURPOSE:To prevent slip between roll and cast piece and avoid damage of gearing mechanism for driving, when changing over the roll after passing through the dummy bar from driving operation to control operation, by providing a buffer circuit in the roll driving motor circuit in the straight part in a curvature type continuous casting apparatus. CONSTITUTION:A continuous cast piece 4 cast in a mold 3 is drawn out by a dummy bar 7 through curvature part A and straight part B. A roll 5 in the straight part B first applies a driving force to the cast piece 4 and draws it out. When the connection part 11 of dummy bar 7 and cast piece 4 passes through, the roll 5 is changed from driving operation to control operation, and compression force is applied to the cast piece 4. Then, roll motors M11 to M15 are switched from the motor operation to the generator operation. At this time, a buffer circuit 18 operates to control sudden changes in the braking force of the roll 5 applied to the cast piece 4, thus preventing slip between the roll 5 and cast piece 4. Therefore, without damaging the driving gear mechanism, the straight part B can be smoothly changed over to the control operation, so that the yield may be enhanced while restricting the quality lowering of the cast piece.
