Oil removing device of cold rolling mill

Abstract

The invention relates to a deoiling device used in a cold rolling mill, in particular to a strip surface process residual lubricating fluid removing device used in a cold-strip mill. The device is characterized in that the head part of a hydraulic oil cylinder is connected with an upper frame, the lower part is fixed on a base by an oil cylinder support, one end of a guide pillar is fixed on the upper frame, and the other end passes through a guide sleeve, and the guide sleeve is welded on the base; a left group of deoiling rolls and a right group of deoiling rolls are respectively arranged on the base and the upper frame, one end of a stretching screw is connected to the upper frame, and a limit block is welded on the base; a nozzle and an injection pipe are respectively arranged on the inlet side and the outlet side of the upper frame by supports, a brattice is connected with the upper frame, and a pump line is arranged at the upper part of the upper frame. The device has the advantages of hydraulic drive, fast response speed, reasonable structural design, convenient and reliable use, a plurality of deoiling measures and high efficiency, is especially applicable to deoiling high-speed cold-strip mills, and can greatly improve the performance of cold rolling mills.

Description

technical field [0001] The invention relates to a degreasing device for a cold rolling mill, in particular to a degreasing device (referred to as the degreasing device) for strip surface technology lubricating residual liquid used on a strip cold rolling mill. Background technique [0002] Cold rolling mills, especially high-speed strip cold rolling mills, during the rolling process, a large amount of process lubricant will be taken away from the rolling area with the operation of the strip, and remain on the upper and lower surfaces of the rolled piece. At present, the degreasing devices commonly used in cold rolling mills can be divided into roller degreasing, belt degreasing, air blowing degreasing, cloth clip degreasing and other types. These degreasing devices have their own characteristics and are suitable for different applications. Degreasing of cold-rolled strips, but their common defect is that they cannot meet the degreasing requirements of high-speed strip cold-r...

Problems solved by technology

At present, the degreasing devices commonly used in cold rolling mills can be divided into roller degreasing, belt degreasing, air blowing degreasing, cloth clip degreasing and other types. These degreasing devices have their own characteristics and are suitable for different applications. Degreasing of cold-rolled strips, but their common defect is that they cannot meet the degreasing requirements of high-speed strip cold-rolling mills

After degreasing, there is often still a considerable amount of process lubricating residue remaining on the upper and lower surfaces of the rolled piece, which is involved in the coiler, which is prone to belt slippage accidents and affects production; at the same time, the strip will slip at the deflector roll, Affects rolling control and strip surface quality
