Automatic control system and method for strip steel surface rust removal

Abstract

The invention discloses an automatic control system for strip steel surface rust removal. The automatic control system comprises a feeding device, an unwinding device, a limiting device, a detecting device, a grinding device, a supporting device, a sucking and removing device, a driving device, a flushing device, a winding device and a control device, wherein according to detecting signals of the detecting device, the control device controls the driving device to sequentially drive the grinding device to partially derust the planar strip steel surface and drive the sucking and removing device to collect rust dust which is ground off and then controls the flushing device to flush the strip steel. The automatic control system for strip steel surface rust removal can automatically detect partial rust on the strip steel surface and automatically remove and clean the partial rust according to the detecting signals, and is high in working efficiency and machining accuracy, the rust is removed thoroughly, the working process is free of pollution, and the removed rust material can be recycled. The invention further provides an automatic control method of the automatic control system.

Description

technical field [0001] The invention relates to the technical field of steel strip processing, in particular to an automatic control system and method for derusting the surface of strip steel. Background technique [0002] Usually, before the cold-rolled strip enters the cold-rolling process, the oxide layer on the surface of the strip needs to be removed. Whether the oxide layer is cleaned or not directly affects the quality of the product, the efficiency of product production and the life of the equipment. There are some existing methods of combining mechanical and pickling to remove the oxide layer. The steel surface is shot blasted to remove the oxide layer with abrasives, and then sent to the pickling process for pickling. However, when the strip surface is partially derusted, the effect is not ideal. , The loss of steel in the pickling process is large, and the acid mist in the production process is very harmful to the human body, the pollution is serious, the waste a...
