Abstract

PURPOSE:To prevent the degradation in quality while suppressing bulging of an ingot under continuous casting at a high speed and preventing the internal cracking thereof by measuring the thickness of the ingot and controlling the rolling reduction of pinch rolls according to the measured value of the thickness. CONSTITUTION:In the pinch roll zone of a continuous casting device, the upper rolls 51, 52 and lower rolls 61, 62 of pinch rolls are disposed in pairs, with an ingot 2 in-between, and the respective three rolls as one set form segments 41, 42. The upper rolls 51, 52 can adjust screw-down respectively independently with screw down devices 71, 72 and the lower rolls 61, 62 are maintained in prescribed positions by plungers (not shown). Thickness gages 81, 82 are installed jut before the inlet of the segments 41, 42, and measuring devices 91a, 91b, 92a, 92b for roll gaps are provided. The respective measured values are inputted to an arithmetic control circuit 10 which determines the deviations from the values set by a target value setter 11, and controls rolling reduction with the devices 71, 72 so as to eliminate the deviations.
