Abstract

The invention relates to a method for determining a wear degree of a wringing roller in pickling, and belongs to the technical field of cold-rolled strip steel pickling. According to the technical scheme of the method, a wringing roller wear time mathematical model is established, and the established mathematical model is utilized in a secondary system to automatically select a length, a running speed, a position load coefficient and a mark load coefficient for producing a current coil; and wear time of the wringing roller at different positions is automatically calculated, when the wear time of the wringing roller reaches a specified value, the wear degree of the wringing roller reaches an optimal state, and periodic replacement can be conducted. The method has the beneficial effects that accurate use tracking of the wringing roller can be effectively realized, accurate control capability of the wear degree of the wringing roller is improved, an accident rate of the wringing roller is reduced by 90% or more, the method plays a great role in pickling quality and stable production of products, and an accurate control problem of the wear degree of the wringing roller is well solved.

Description

Technical field[0001]The present invention relates to a method of determining the degree of squeezing roller wear in the acid washing, belonging to the field of cold rolled strip.Background technique[0002]The acid rolling unit is the first treatment process for cold rolling, and the main function is to prepare for subsequent processing, squeeze roll applications for subsequent processing, squeezing roller applications for subsequent processing. For pickling sections and rinsing segments, used to squeeze the surface of steel to ensure the quality of the strip surface. For example, a total of 12 pairs of squeezed roller roller roller roller rolling roller rolling rolling roller is 1 #, 2 #, 3 # .... 11 #, 12 #, where 1-4 # squeezed roller is applied to the pickling section, 5-12 # Squeezing roller is applied to the rinse segment, the use of the roller system is different, and the wear situation is different. In the unit production without a grade steel, the squeezed roller wear is not...
