Emulsion cleaning device

Abstract

The invention relates to an emulsion cleaning device, which consists of an air curtain purging device for an upper anti-wrap guide plate of a rolling mill, a purging device for the middle of the upper part of a strip, a roll gap purging device, a purging device for the upper part of the strip, a lower anti-wrap guide plate suction device, and a purging device for the edge of the lower surface of the strip. By the combination action of a series of strip surface purging, roll gap purging, sucking, edge purging and the like, the strip surface emulsion purging effect is very obvious and the residual oil amount on the surface of the strip can completely meet the requirement of the user for the surface quality of the finished strip. By the emulsion cleaning device, the surface quality of the product is improved and the economic benefit of the user is increased. The emulsion cleaning device not only has very good application effect in a cold continuous rolling mill, but also can have wide application in a plurality of sets such as a single-stand reversing cold mill, a double stand reversing cold rolling mill, a planisher and the like, can be greatly popularized and used in the cold rolling industry and brings convenience and benefits for more users.

Description

technical field [0001] The emulsion removal device described in the present invention relates to the field of cold rolling technology, in particular to an emulsion removal device on the surface of a strip. Background technique [0002] At present, the rolling speed and output of the world's tandem cold rolling mills are developing towards high speed, and major steel mills are trying every means to improve product quality and output. In the quality requirements of the product, the residual amount of emulsion on the surface of the strip is a very important quality indicator. When cold-rolled products enter the next process, such as galvanizing and tin plating, if the amount of residual oil is too large, it will cause very serious consequences. Due to the high exit speed of the cold tandem rolling mill, how to clean the emulsion between the exit of the strip from the rolling mill and the flat roll has been perplexing various steel mills. The design departments of various count...
