Embodiment Construction

[0019] like figure 1 as shown, figure 1 A structural schematic diagram of an automatic control system for implementing an automatic control method for strip steel surface defect shaping proposed by the present invention.

[0020] An automatic control method for shaping the surface defects of the strip steel proposed by the present invention is used to detect the surface defects of the strip steel and carry out shaping of the surface defects, and is characterized in that it comprises the following steps:

[0021] Strip feeding: develop coiled strips into flat strips and feed them. During the flat strip feeding process, the feeding track of the flat strips is controlled by the horizontal limit mechanism set on the left and right and the vertical limit mechanism set up and down. Carry out limit;

[0022] Defect detection: the distance L1 from the detection probe to the upper surface of the flat steel strip is detected by the first detector, the distance L2 from the detection pr...

Abstract

The invention discloses an automatic control method for surface defect shaping of strip steel. The automatic control method for surface defect shaping of the strip steel comprises the steps of feeding, rough rolling, detecting, material supplementing, polishing, washing, knocking and winding, wherein rough rolling is conducted on the planar strip steel, the surface of the planar strip steel is detected, the defect type is judged according to a detection signal, and at least one of material supplementing, polishing and knocking is conducted on the portion, with a shape defect, of the surface of the strip steel according to the defect type and the position. According to the automatic control method for surface defect shaping of the strip steel, the defect on the surface of the strip steel can be detected automatically, the defect type is judged according to the detection signal, at least one of material supplementing, polishing and knocking is adopted for conducting corresponding shaping on different shape defects on the surface of the planar strip steel according to the defect type, in this way, fine shaping of tiny shape defects on the surface of the strip steel is achieved, working efficiency is high, the shaping effect is good, secondary damage is avoided during shaping, and the smoothness of the surface of the shaped strip steel is high.

Description

technical field [0001] The invention relates to the technical field of steel strip processing, in particular to an automatic control method for shaping surface defects of strip steel. Background technique [0002] Usually, the steel strip made by cold rolling needs to be leveled. Leveling means that the strip steel after recrystallization annealing is rolled with a small amount of deformation to eliminate the yield stress, ensure mechanical properties, and control the shape of the strip to reduce Defects in the surface morphology of the steel strip produced during the cold rolling process. Since leveling is the last process that determines the shape and mechanical properties of the finished strip, it is of great significance to ensure the quality of cold-rolled strip. However, the existing shaping equipment cannot perform fine shaping according to the type of shape defect, which will affect the flatness of the strip surface and even cause secondary damage to the strip quali...
