Auxiliary cooling and cleaning system for cold rolling mill

Abstract

The invention discloses an auxiliary cooling and cleaning system for a cold rolling mill. The auxiliary cooling and cleaning system comprises a base and supporting plates; a motor is welded and fixed to the side wall of one supporting plate; a rotating shaft is welded and fixed to the output end of the motor; a working roller is welded and fixed to the rotating shaft; a rectangular plate is welded and fixed to the tops of the two supporting plates jointly; heat conducting pieces are arranged on the inner wall of the working roller; two grooves are symmetrically formed in the bottom of the rectangular plate; magnetic bars are glidingly connected in the grooves; scraping plates are welded and fixed to the bottoms of the magnetic bars; a sliding cavity is formed in the inner wall of the rectangular plate; an electromagnetic valve is arranged at one end of the sliding cavity; a power generation component is arranged in the sliding cavity; and electromagnets are symmetrically arranged in the rectangular plate. The auxiliary cooling and cleaning system has the advantages that a fan, an air suction hole, the scraping plates and other structures are arranged, and cooling water, impurities on the working roller and the like are guided to the two ends of the working roller through the scraping plates, so that the cooling water, the impurities and the like are sucked by the air suction hole to be stored and recovered, and the condition that the surface quality of a plate is affected due to the fact that oil dirt and other impurities fall on the plate is avoided.

Description

technical field

[0001] The invention relates to the technical field of cold rolling mills, in particular to an auxiliary cooling and cleaning system for cold rolling mills. Background technique

[0002] The cold rolling mill is a kind of cold rolling (normal temperature) processing equipment for metal materials. The cold rolling mill includes structures such as racks, rolls and roll bearings. The rolls are divided into load rolls and work rolls. The bearing roll of the cold rolling mill plays a supporting role during production. The work roll of the cold rolling mill is on the bearing roll and is the farthest away from the stand, so the roll mainly plays the role of rolling.

[0003] However, when the existing cold rolling mill is rolling, if the rolling pressure is too large, the thickness of the plate is thick, etc., the temperature of the plate and the surface of the work roll will increase abnormally, and only rely on the cooling of the cold rolling mill. The system can...
