With the continuous development of industry, the application of cold-rolled thin sheet products (hot-dip galvanized products) is becoming more and more widespread. They are widely used in industrial industries such as automobile manufacturing, home appliances, and hardware, and their market demand is gradually increasing. The construction of cold rolling plants is also increasing synchronously. The finishing machine is an important equipment in the cold rolling line and an important component of the hot-dip galvanized product production line. After cold rolling and annealing, the strip steel is, It is also necessary to perform small deformation finishing through a finishing machine to eliminate yielding platforms, improve mechanical properties, and control the surface morphology and plate shape of the strip steel. As finishing is the final process that determines the shape of the finished strip steel plate, the finishing machine has become an indispensable and important process equipment for hot-dip galvanizing lines.

With the increasing demand for the quality of hot-dip galvanized products in the market, the daily maintenance of the finishing machine has become crucial. In the operation of the finishing machine, it is not only necessary to adjust the problems caused by vibration faults in a timely manner, but also to pay attention to the cleaning of the working roller surface of the finishing machine. Because after a period of operation, the working roller surface of the finishing machine is prone to adhering zinc particles, which will produce obvious roller marks on the surface of the strip steel, which will seriously affect the surface quality of the strip steel, Therefore, it is necessary to clean the working roller surface in a timely manner to eliminate zinc sticking on the roller surface. The cleaning method of the work roller determines whether the roughness of the roller surface can be maintained for a long time.
