  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To control the position of the rolled material's center to an arbitrary point along the roll axis, and to carry out the rolling work under the uniformly distributed rolling load, by controlling the pressure control valves connected to the screw down cylinders installed on the driving side and the operating side of the rolling mill, depending on the offset of the rolled material's center from the rolling mill's center.
CONSTITUTION: The driving side screw down cylinder 4A and the operating side screw down cylinder 4B are installed respectively under the driving side lower backup roll bearing 3A and the operating side lower backup roll bearing 3B of the reducing rolls 2 of the rolling mill 1. The cylinders 4A, 4B, are connected to the pressure control valve 6 respectively through the special changeover valves 5A, 5B. Besides, the pressure control valves 11A, 11B, are connected to the pressure oil unit 8 through the direction control valve 22, and also, are connected to the upper closed chambers of the cylinders 4A, 4B. Hereupon, the pressure of the upper closed chambers of cylinders 4A, 4B, can be controlled to arbitrary valves by operating the driving mechanisms 12A, 12B, for putting on or off the pressure control valves 11A, 11B. According to this constitution, the offset rolling work is possible, and the rolling work can be carried out at an arbitrary position of the rolled material 23 without necessity of fixing its traveling position at a specified point.
