Title: Method for drawing ingot for continuous casting machine
Inventor: TSURU NOBURO
IPC: B22D11/128
Filed: 1987-03-05
Abstract: PURPOSE:To prevent generation of surface defects in an ingot by disposing plural pairs of pinch rolls, setting different rotating speeds to the respective pinch rolls and applying the torque in the specified direction to said rolls. CONSTITUTION:Plural pairs of the pinch rolls 3a-3e are disposed on the down stream side of a guide roll group 2 of a continuous casting machine. The pinch rolls 3a-3e are so controlled by a driving control device that the revolving speeds thereof vary from each other. Compressive stresses are applied to the surface of an ingot and the torque in the specified direction is applied at all times to the respective pinch rolls 3a-3e. Generation of a speed fluctuation by a backlash is, therefore, obviated even if the load on the pinch rolls 3a-3e fluctuate. The speed fluctuation of the ingot and the molten metal level fluctuation in a casting mold are, therefore, suppressed and the generation of surface defect in the ingot is prevented.
