Rolling mill thickness intelligent control system

Abstract

The invention discloses a rolling mill thickness intelligent control system, and belongs to the field of rolling mill thickness control. The system comprises a main motor which enables a roller to move in the horizontal direction to convey metal, a main frequency converter which controls the rotating speed of the main motor, a servo motor which drives the roller to move in the vertical direction for metal rolling, a servo driver which drives the servo motor to rotate, an encoder which detects the rotating speed of the servo motor, a first position sensor which detects the size of a roller gap,and a control unit which receives the size of the roller gap transmitted by the first position sensor and the rotating speed, transmitted by the encoder, of the servo motor. The control unit starts the main frequency converter to control the main motor to rotate, and the main motor enables the roller to move in the horizontal direction for metal conveying. Meanwhile, the control unit controls theservo driver to drive the servo motor to enable the roller to move in the vertical direction, the size of the roller gap is adjusted to conduct metal rolling, the system can be applied to a rolling mill workshop, and the working efficiency, the machining precision and the man-machine safety can be improved.

Description

technical field [0001] The invention relates to the field of rolling mill thickness control, in particular to an intelligent control system for rolling mill thickness. Background technique [0002] At present, the rolling thickness control of most rolling mills is controlled manually by factory technicians, which not only poses potential dangers to the personal safety of technicians, prevents the labor force from being fully utilized, and is also not conducive to improving production efficiency. Promote the process of industrial production automation and intelligence. Existing rolling mill thickness control technologies are often aimed at rolling mills with hydraulic servo systems, and the specific control methods mainly include two types: position control and pressure control. The position control is to use the thickness gauge to monitor the thickness change of the roll gap before and after rolling, and form a closed-loop control through the feedback of the thickness, whil...
