A kind of degreasing method of plate degreasing system for cold rolling mill

Abstract

The invention discloses a degreasing method for a plate degreasing system for a cold rolling mill. It includes the following steps: S1, start the electric push rod, push the cold air pipe down, and the oil-absorbing sponge is attached to the surface of the plate; S2, high-pressure gas delivery, send the high-pressure gas into the vortex tube through the high-pressure air intake pipe, the hot gas enters the heat pipe, and the cold air enters the cold air. Tube; S3, temperature difference manufacturing, the temperature of the lower end of the oil-absorbing sponge rises, the temperature of the upper end of the oil-absorbing sponge drops, and the temperature difference between the upper and lower parts of the oil-absorbing sponge; S4, the oil-water absorption of the plate, the oil-water at the lower end of the oil-absorbing sponge continues to move to the upper end of the oil-absorbing sponge , so that the lower end of the oil-absorbing sponge can continuously absorb the oil stains on the surface of the board. The invention can efficiently remove the residual rolling liquid on the surface of the plate by setting the oil-absorbing sponge and the temperature difference manufacturing mechanism, and avoids the surface of the plate from being scratched by impurities such as iron filings and copper filings during friction, and improves the yield of the cold rolling mill. , which can better meet the actual production requirements.

Description

technical field

[0001] The invention relates to the technical field of cold rolling mills, in particular to a degreasing method of a plate degreasing system for cold rolling mills. Background technique

[0002] The existing plate cold rolling mill needs to spray high-viscosity rolling oil to the plate rolling area and add corresponding additives when needed. Therefore, after the plate passes through the cold rolling mill, a certain amount of rolling oil will remain on the surface of the plate. Oil production, when there is too much residual process rolling oil on the surface of the plate, it is easy to produce misalignment when the plate is coiled, and even fall out when the plate is rolled at high speed, causing accidents, and the surface of the plate after annealing will produce marks and oil spots, resulting in Quality defects will greatly reduce the finished product, so an oil removal device needs to be installed at the exit of the cold rolling mill.
