Background
Because the cold rolling pickling line is inevitably stopped, equipment such as a roller, a wringing roller, a tension meter roller and the like is replaced. Shutdown processing is also required when equipment failure is encountered. At this time, the strip steel staying in the rinsing tank generates a parking spot on the surface of the strip steel in a short time under the environment of a micro-acid solution. When the pickling line is run at very low speeds, it may also lead to the occurrence of stopping marks on the strip surface. The stopping spot is a defect generated on the surface of the strip steel due to secondary oxidation reaction caused by overlong stay time of the strip steel in the rinsing tank. If the parking spots are not eliminated, on one hand, the subsequent rolling is affected, the belt breakage accident is easily caused, and the normal operation of the unit is affected; on the other hand, after the strip steel is rolled by a rolling mill, the strip steel is degraded due to surface defects due to the existence of parking spots, so that loss is caused.
