Abstract

The invention discloses a rolling deoiling device. The rolling deoiling device comprises a pair of stands, a deoiling mechanism and lifting cylinders, wherein the stands are used for bearing and installing the deoiling mechanism and the lifting cylinders; the deoiling mechanism comprises an oil suction roller, a pair of bearing structures, bottom plates and slide bases, the end portions of the oilsuction roller are arranged on the bottom plates on the corresponding sides through the bearing structures, and the bottom plates are arranged on the slide bases on the corresponding sides; the lifting cylinders are fixed to the stands, and piston rods of the lifting cylinders are connected with the slide bases. By means of the rolling deoiling device, the problems that an oil suction roller is deformed and bent, and the ascending and descending motions of the two sides of the oil suction roller are non-synchronous, it is effectively ensured that the oil suction roller stably runs for a longperiod, and the efficiency and effect of adsorbing remaining lubricating oil / emulsions are improved. Through the internal negative-pressure adsorption, the oil suction roller can further improve the deoiling effect.

Description

technical field

[0001] The invention relates to the technical field of strip rolling, in particular to a rolling degreasing device. Background technique

[0002] In the steel rolling industry, strips often need to be rolled through a rolling mill. However, a large amount of emulsion is used for cooling and lubrication during the rolling process, which results in a large amount of residual emulsion on the surface of the strip after rolling. These emulsions can further form emulsion spots, leading to product surface defects.

[0003] Most of the existing degreasing devices simply set up a pair of oil-absorbing rollers. The two ends of the oil-absorbing rollers are respectively arranged on the archway. It is asynchronous with the operation up and down movement; due to the very high rolling speed, the bent and deformed oil absorption roller will vibrate violently when it rotates with the strip steel, so it cannot operate normally and absorb the residual emulsion. At present, t...
