Embodiment Construction

[0015] Such as figure 1 As shown, the rolling mill includes an uncoiler 101 and its pressure roller 102, telescopic guide plate 103, leveler 104, entrance tension roller 105, CPC 106, wedge 107, two back rollers 108, two worker rollers 109, two Push up the hydraulic cylinder 110, the exit tension roller 111 and its pressing roller 112. From the same direction gradually away from the unwinding machine 101, telescopic guide plate 103, leveler 104, CPC106, two work rolls 109, outlet tension roll 111 and pressure roll 112 thereof are arranged successively, and entrance tension roll 105 is located at work roll 109 and Between unwinding machines 101. Two working rollers 109 are arranged parallel to each other, and there is a working gap between them. A backing roller 108 is respectively arranged on the outside of the two working rollers 109. Wedges 107 are arranged on the backing roller 108 positioned at the top, and two Push up the hydraulic cylinder 110. The uncoiler 101 set is...

Abstract

The invention discloses a control system for the thickness of a rolled plate. The control system comprises a plate thickness control unit, an operation control unit, a rolling mill control unit, a main control unit, at least two thickness measurers and at least two hydraulic cylinder servo valves, wherein the main control unit is connected with the plate thickness control unit, the operation control unit and the rolling mill control unit respectively, and sends commands of start-up, deceleration, acceleration or stop to a rolling mill after receiving instructions of the plate thickness control unit. According to the control system disclosed by the invention, if the thickness of the rolled plate exceeds a set range value via detection carried out through feeding back detection data of a thickness measurer control system to a plate thickness control module, the rolling mill realizes automatic deceleration and stops, thus breakage of a steel belt due to thickness fluctuations is avoided, and the production cost is effectively saved; and in particular, monitoring for the thickness of the rolled plate is exerted better on the basis of the thickness measurers, and unit personnel can much conveniently operate.

Description

[0001] The patent application for the present invention is a divisional application of the Chinese invention patent application with the application number 201410640385.8 and the filing date of November 13, 2014. The invention title of the original application is "A Control Method and Control System for the Thickness of a Rolled Plate". technical field [0002] The invention relates to a steel strip production equipment, in particular to a control system for rolling plate thickness. Background technique [0003] When the existing reversible rolling mill is cold-rolled to produce steel strips, in the first pass of production, there is a thickness gauge before and after the rolling mill. The steel strip enters the rolling line, and the crew starts the first pass of rolling. During the process, when the thickness of the raw material steel strip fluctuates, it is easy to cause abnormal accidents such as broken strips and flying plates, which greatly increase the production cost ...
