Abstract

The invention provides an air purging nozzle for rolling production. The air purging nozzle comprises a flat nozzle, a position pointer and an indicating dial, wherein the indicating dial is fixed on a mounting base; the position pointer is positioned on the flat nozzle; the position pointer and the flat nozzle are hinged with the indicating dial through a hinged joint; the flat nozzle comprises an air inlet, an air outlet and a nozzle body; the side part of the nozzle body is provided with an annular groove; an adjusting bolt runs through the annular groove and is connected with the indicating dial; the adjusting bolt is locked or loosened to realize the locking or separation between the flat nozzle and the indicating dial; the inside of the nozzle body is provided with a hollow cubage cavity; the air inlet is communicated with the air outlet through the hollow cubage cavity of the inside of the nozzle body; and the section of the air outlet is rectangular. The air purging nozzle has the characteristics of stable outlet pressure, even current distribution, less air consumption and low noise; the position indication is convenient for field adjustment and process stability; and the air purging nozzle has energy conservation and environmental protection, is a new practical design, and is simple and applicable.

Description

technical field [0001] The invention relates to an air purging nozzle for rolling production, which belongs to the technical field of machinery for rolling production process. Background technique [0002] The cooling and lubricating rolling oil sprayed during the production process of plate and strip forms residual oil on the surface of the strip for various reasons. The existence of residual oil affects the rolling production efficiency and the surface quality of the strip. The method of removing these residual oils is to use the nozzles used for air blowing. Traditionally, there are many small nozzles arranged in a certain way; the airflow interference between multiple small nozzles will reduce the blowing efficiency; moreover, the nozzles It is difficult to adjust the spray angle at the production site and replace it after a failure. [0003] Patent 95222025.3 discloses "cold-rolled strip emulsion purging device", patent 96211941.5 reports "cold rolling mill end stand o...
