Plate shape automatic adjusting system

Abstract

The invention discloses a plate shape automatic adjusting system. An inlet end plate shape image acquisition unit and an outlet end plate shape image acquisition unit are mounted at the positions, between an inlet rolling shaft and a roll and between an outlet rolling shaft and the roll, of a rolling mill hood, and the plate shape image acquisition units are in communication connection with a central processing unit. Firstly, a received and obtained inlet end plate shape image sent by the inlet end plate shape image acquisition unit is compared with historical data of a database, the most similar image in the database is calculated, adjusting data adopted by the most similar image are read, and a rolling mill control system is instructed to perform adjusting according to the adjusting data; and then an outlet end plate shape image sent by the outlet end plate shape image acquisition unit is received and obtained, and the outlet end plate shape image is compared with the historical data of the database again through the central processing unit based on closed-loop control and adjusted till plate shape automatic adjusting conditions are met. The plate shape automatic adjusting system is high in automatic adjusting degree, meanwhile has a graph learning calculation function, and is further beneficial to plate shape adjusting precision.

Description

technical field [0001] The invention relates to the field of steel plate manufacturing, in particular to a plate shape automatic adjustment system. Background technique [0002] With the intensification of competition among domestic cold-rolled steel plate (full hard plate) manufacturers, many domestic steel cold-rolled companies are extending their products to high-end and high value-added directions. The shape quality of cold-rolled raw materials for home appliance panels is one of the most important factors determining the quality of home appliance panels. Among the quality defects of cold-rolled substrates for home appliances, poor shape is one of the major defects of home appliance panels; it can also be said that poor shape defects are the decisive factor determining the surface quality of cold-rolled substrates, and usually account for the largest monthly quality loss. The ratio. [0003] Therefore, improving the shape of cold-rolled steel sheets has become one of t...

Problems solved by technology

At present, the advanced cold-rolled steel plates for the production of home appliance plates at home and abroad have applied the tandem rolling mill mode, and the flatness of the last pass of the tandem rolling mill is used to improve the shape of the steel plate. Production can only work on one stand, and its working method determines that in the production of household appliances, it cannot use different units to equip different rolls like high-end continuous rolling mills, and use the leveling process of the last stand to improve the shape of the steel plate. It is also impossible to use different racks to adjust the shape of the board, and to improve the frequency and defect degree of the bad shape by using different racks, so it is impossible to refer to other existing methods for improving the bad shape of the board to achieve its shape. improve

[0004] Specifically, during the rolling process of traditional reciprocating cold rolling mills, problems such as edge waves, quarter waves, medium waves, and cambers will appear on the steel plate, and the traditional automatic control system is difficult to have a good learning function , once the plate type is abnormal under the traditional automatic control system, it is difficult to automatically update the original database automatically under manual intervention
