Background
The electrolytic cleaning is a necessary production process in the cold rolling production process of the metallurgical industry, and the electrolytic cleaning is a core link of the cleaning process integrating spray cleaning, brushing, hot water rinsing and drying in the cold rolling strip processing and cleaning process.
The electrolytic cleaning tank body adopts a vertical three-dimensional design, one tank body is formed, 4 passes of steel strips pass through the tank, and each pass is provided with a front electrode plate and a rear electrode plate for connecting +36V and-36V voltages respectively; in order to realize the passing of the steel belt of 4 passes, 5 rollers are required to be arranged in the groove to realize the steering operation of the steel belt and the operation driving of the steel belt, and meanwhile, in order to keep the steel belt in the operation process to operate in the center of the roller surface, the 5 rollers are all made of polyurethane rubber roller surfaces to increase the transverse friction force between the roller surface and the steel belt, so that the steel belt always operates in the center of the rollers. In addition, in order to enable the rollers to drive the strip steel to run in a specified direction, a certain radial friction force needs to be established between the rollers and the surface of the strip steel, so that the strip steel can be driven to run, the bending force needed by the turning of the strip steel at the rollers is supplemented, and the rubber rollers are also used at the positions to meet the requirement of the friction force based on the factor.
Although the friction force between the steel belt and the roller can be improved by using the rubber roller with the polyurethane roller surface, the steel belt is in contact with the rubber roller with the polyurethane roller surface, so that the steel belt cannot be well conducted with the ground, charges accumulated on the steel belt cannot be effectively released, the steel belt is positioned at a steel belt point in the subsequent 3 times of brushing grooves, rinsing grooves and drying processes, therefore, fine particles attached to the surface of the steel belt are not easy to separate due to the fact that the fine particles are adsorbed on the surface of the steel belt, and the foreign charged particles in the nearby space are adsorbed on the surface of the steel belt, so that the cleaning quality is greatly reduced. In addition, the glue film of polyurethane roller face is attached to on the steel base roll, because there is great effort in glue film and roll surface, the life of polyurethane roller face is shorter, often needs to be changed 10 months, has so not only improved spare part and has overhauld the load capacity and the cost of changing, has still increased the trouble risk that roller surface glue film and base roll drop.
Therefore, how to avoid the influence on the cleaning effect of the steel strip caused by the adhesion of charges and particles on the surface of the steel strip is a technical problem that needs to be solved by those skilled in the art.
