The coating process does not require an additional motor to reduce costs; at the same time, the water pump 18 is started to ensure that the rolling oil is transported from the liquid storage tank 17 to the coating brush 15. After the iron plate is rolled, the cleaning brush 25 removes excess rolling oil and impurities on the surface, so as to realize the recycling of rolling oil and improve the efficiency of resource utilization.
