Abstract

The invention provides a steel plate straightening method. The steel plate straightening method comprises the steps that whether a rolled steel plate is abnormal or not is judged, if the rolled steelplate is abnormal, steel plate parameters of the steel plate are input, new straightening parameters are obtained through calculation according to the steel plate parameters, the new straightening parameters are sent to a basic automatic control system, and the basic automatic control system controls a straightener to straighten according to the new straightening parameters. According to the steelplate straightening method, calculating the steel plate parameters of the abnormal steel plate is carried out to obtain the new straightening parameters, the straightener is controlled to straightenaccording to the new straightening parameters, and the straightened abnormal steel plate is obtained, so that the shape of the steel plate is guaranteed, and the waste quantity is reduced.

Description

technical field [0001] The present application relates to the technical field of metal material processing, in particular to a steel plate straightening method. Background technique [0002] In order to ensure the shape of the steel plate, the production line is equipped with an online multi-roller straightening machine. In the production process, after the steel plate is rolled, it is transported to the straightening machine by the roller table for straightening. [0003] The traditional straightening method is that the process automation control system calculates the appropriate parameters such as the entrance roll gap, exit roll gap and speed of the straightening machine through the straightening model according to the steel plate detection temperature, steel type, specification, etc., and sends each parameter to the Basic automatic cleaning control system, the basic automatic control system presets the straightening parameters and empty parameters of the straightening m...
