In the rolling process of the cold-rolled strip steel, the emulsion plays an important role as a medium for rolling lubrication and cooling, and meanwhile, whether the emulsion can be fully purged from the surface of a strip steel plate or not in the rolling process has a great influence on the quality of the rolled plate surface. However, the existing cold rolling unit has high running speed and large emulsion flow, so that the emulsion on the surface of the strip steel is difficult to remove, and once the residual amount of the emulsion is too large, burnt-shaped corrugated marks are generated after annealing treatment, and the quality of the strip steel is seriously influenced.
In order to remove the residual emulsion on the surface of the strip, a compressed air blowing device is usually provided at the outlet side of the cold continuous rolling mill to blow off the residual emulsion on the surface of the strip. But the compressed air purging device has not ideal purging effect on the emulsion remained on the edge of the strip steel for a long time: firstly, because the product specifications of the existing cold rolling continuous production line are frequently switched on line, the generally adopted fixed purging device cannot effectively purge the edges of the strip steel with different width specifications, and even if some production lines are provided with purging devices aiming at the edges of the strip steel, the defects of low automation degree, low adjustment precision, inconvenience in operation and maintenance, high failure rate, high environmental requirement and the like exist, so that the purging effect is influenced; secondly, because of the existence of empty roll gaps at the two sides of the edge of the strip steel, a large amount of emulsion is thrown out along with the rotating working roll, and the emulsion thrown to the edge of the surface of the strip steel cannot be blown off in time by a compressed air blowing device arranged in the frame; thirdly, if the thrown residual emulsion cannot be blown off in time, the adhesion amount and the adhesion width of the residual emulsion randomly formed on the edge of the strip steel are uncertain, so that the adjustment difficulty of the blowing device is increased.
