Problems solved by technology

The scale breaking machine currently used mainly adopts the principle of tension scale breaking. In order to increase the scale breaking force, the method of increasing the tension is often used. In this method, due to the large tension, it is easy to cause plastic deformation of the steel plate and destroy the shape of the plate. , is not conducive to subsequent processing, and will affect product use in severe cases

Abstract

The invention provides a scale breaking unit control system used before strip steel acid pickling and belongs to the technical field of pretreatment before strip steel acid pickling. The control system comprises a plate and strip conveying system, a hydraulic screw-down system, a scale breaking unit, a motor drive unit, a motor control system and drive motors. The control system particularly comprises an inlet welding platform, an inlet clamping and conveying roller, an inlet unit, a screw-down hydraulic cylinder, a built-in clamping and conveying roller, transmission shafts, a reduction gearbox, an outlet unit, an outlet hairbrush roller, front fixed scale breaking rollers, front movable scale breaking rollers, rear fixed scale breaking rollers and rear movable scale breaking rollers. The rear portion of the inlet welding platform is connected with the inlet clamping and conveying roller, the inlet unit is arranged behind the inlet clamping and conveying roller, and finally scale breaking of strip steel is completed through the outlet unit and the outlet hairbrush roller behind the outlet unit. The motor control system controls the drive motors of the whole system through the motor drive unit. By the adoption of the control system, the better scale breaking effect is achieved under the condition of not destroying the plate shape, hydrochloric acid is saved, and besides the production line speed is increased.

Description

technical field [0001] The invention relates to the technical field of pretreatment before pickling of strip steel, in particular to a control system of a scale breaking unit before pickling of strip steel. Background technique [0002] In the current technology, in order to improve the pickling effect and save the cost of acid before the pickling line treatment of the steel plate, a scale breaking unit is generally installed before the steel plate enters the acid tank, so that the iron oxide scale attached to the steel plate is formed. Certain cracks are provided to facilitate the acid to enter the joint between the iron oxide scale and the iron base to increase the pickling speed. The scale breaking machine currently used mainly adopts the principle of tension scale breaking. In order to increase the scale breaking force, the method of increasing the tension is often used. In this method, due to the large tension, it is easy to cause plastic deformation of the steel plate ...
