Removal device of emulsion remained on surface of strip steel used for cold rolling mill

Abstract

A removal device of emulsion remained on the surface of strip steel used for a cold rolling mill belongs to the technical field of auxiliary facilities of the cold rolling mill. The cold rolling mill comprises a strip steel rolling mechanism which consists of an upper supporting roller, a lower supporting roller, an upper work roller and a lower work roller. The removal device of emulsion remained on the surface of strip steel comprises a pair of blowing mechanisms, a pair of strip steel surface emulsion scraping mechanisms and an upper supporting roller surface emulsion removing mechanism; the pair of strip steel surface emulsion scraping mechanisms are fixed on the rack of a cold rolling mechanism and corresponding to the two sides of the upper work roller and the lower work roller along the length direction; the pair of blowing mechanisms are positioned outside the pair of strip steel surface emulsion scraping mechanisms and fixed with the rack; and the upper supporting roller surface emulsion removing mechanism is fixed on a roller shaft seat of the upper supporting roller, corresponds to the above part of the upper supporting roller in the length direction and is contacted with the upper supporting roller. The removal device of emulsion remained on the surface of strip steel has the advantages that the speed of the cold rolling mill can be improved, the production efficiency is improved, and zinc plating quality of a follow-up zinc plating process can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of auxiliary facilities for cold rolling mills, and in particular relates to a device for removing residual emulsion on the surface of steel strips for cold rolling mills. Background technique [0002] In the process of cold rolling the strip steel in the cold rolling mill, the work roll and backup roll of the cold rolling mill need to be cooled, and the medium used for cooling is emulsion, when the strip steel passes between the upper and lower work rolls At the same time, a large amount of emulsion is inevitably attached to the surface of the strip. If the emulsion on the surface of the strip is not effectively removed, the subsequent galvanizing process will not be able to galvanize well on the surface of the strip. The current solution is to equip a purge device on both sides of the upper and lower work rolls in the length direction and corresponding to the top of the strip. When the strip moves from lef...

AI Technical Summary

Problems solved by technology

Although the above treatment method can reduce the residual amount of emulsion on the surface of the strip to a certain extent, it will seriously affect the cold rolling efficiency.

[0004] The applicant believes that the above-mentioned measures to solve the problem are negative measures that take into account one thing and lose another. The so-called focus on this means only paying attention to the removal effect of the residual amount of emulsion on the surface of the strip; The rolling efficiency of the rolling mill on the strip, but also leads to an increase in energy consumption such as oil consumption per ton of steel
