Background
The cold rolling and pickling production line is inevitably shut down to replace devices such as a roller, a drying roller, a tension meter roller and the like. Shutdown processing is also required when equipment failure is encountered. In the condition that the steel strip stays in the rinsing tank in the weak acid solution, the surface of the steel strip generates parking spots in a short time. When the pickling line is run at very low speeds, it may also lead to the generation of stop marks on the strip surface. The parking spot is a defect that the surface of the strip steel is generated due to the fact that the strip steel stays in the rinsing tank for too long time and secondary oxidation reaction occurs. If the parking spots are not eliminated, on one hand, the subsequent rolling is influenced, the belt breakage accident is easy to cause, and the normal operation of the unit is influenced; on the other hand, after the strip is rolled by the rolling mill, the presence of the parking spots causes the degradation of the strip due to surface defects, which leads to loss.
