Production method and system used for hot-rolled electrical steel and capable of controlling edge warping

Abstract

The invention particularly relates to a production method and system used for hot-rolled electrical steel and capable of controlling edge warping, and belongs to the technical field of steel surface quality inspection. The method comprises the steps that a database of edge warping of the hot-rolled electrical steel is established, and the database includes warping types, warping occurrence reasons of the warping types and warping occurrence areas; the surface of the hot-rolled electrical steel to be subjected to quality inspection is recognized and compared with the database, and the warping type of surface warping of the hot-rolled electrical steel to be subjected to quality inspection is obtained; according to the warping type of surface warping of the hot-rolled electrical steel to be subjected to quality inspection, the warping occurrence reason and the warping occurrence area of the type of warping are obtained; production operation is adjusted according to the warping occurrence reason and the warping occurrence area, so that edge warping of the hot-rolled electrical steel is reduced. According to the method and the system, edge warping is accurately classified and recognized, the generation reason of edge warping can be accurately distinguished, targeted measures are adopted to prevent defect expansion, the defect generation amount is reduced to the maximum extent, and the quality control level is improved.

Description

technical field [0001] The invention belongs to the technical field of steel surface quality detection, and in particular relates to a production method and production system of hot-rolled electrical steel for controlling edge warping. Background technique [0002] As the production technology of hot-rolled electrical steel tends to be mature and stable, surface defects have become the bottleneck restricting the improvement of electrical steel production technology, especially the curling of the hot-rolled edge has seriously affected the improvement of the yield and production capacity of the whole process. At present, the online surface defect detection technology can detect edge warping defects very well, but it cannot be accurately classified, the cause and area of ​​the defect cannot be clarified in time, and the production line cannot be adjusted in time, which may cause batches of defective rolls to occur and continue If the time is too long, it will greatly affect the...

Problems solved by technology

At present, the online surface defect detection technology can detect edge warping defects very well, but it cannot be accurately classified, the cause and area of ​​the defect cannot be clarified in time, and the production line cannot be adjusted in time, which may cause batches of defective rolls to occur and continue. If the time is too long, it will greatly affect the improvement of product quality and increase the quality of cutting loss.

At present, there are few related technologies for edge warping of electrical steel, and there is no relevant achievement on how to quickly classify edge warping through shape recognition
