A process for removing magnetic powder from oily steel plate with porous surface

Abstract

The invention discloses a process for removing magnetic powder from an oil-containing steel plate with a porous surface, which belongs to the field of steel plate cleaning. A process for removing magnetic powder from an oil-containing steel plate with a porous surface involves spraying embedded brush balls with a cleaning agent on the surface of the steel plate and heating. The bottom of the embedded brush ball melts, and the cleaning agent inside and the powder-absorbing rolling ball fall down. The two, together with the extension bristles, contact the surface of the steel plate. Under the action of the magnetic plate, the powder-absorbing rolling ball and the extension bristle move on the surface of the steel plate. The friction effect, combined with the function of the ball brush, can extend into the pores on the surface of the steel plate. On the one hand, it can significantly improve the removal of oil stains in the pores on the steel plate surface. On the other hand, it can effectively absorb the magnetic powder in the pores of the steel plate. The synchronous removal can significantly improve the degreasing and magnetic powder removal efficiency of the steel plate, and the powder suction rolling ball can store the magnetic powder after adsorption, effectively avoiding the secondary adhesion of the magnetic powder to the steel plate, thereby effectively ensuring the overall degreasing and magnetic powder removal efficiency.

Description

technical field [0001] The invention relates to the field of steel plate cleaning, in particular to a process for removing magnetic powder from oil-containing steel plates with porous surfaces. Background technique [0002] The steel plate is a flat steel material that is poured with molten steel and pressed after cooling. It is flat, rectangular, and can be rolled directly or cut from a wide steel strip. Steel plates are classified according to their thickness, thin steel plates < 4 mm (thinnest 0.2 mm), medium-thick steel plates 4-60 mm, and extra-thick steel plates 60-115 mm; steel plates are divided into rolling, hot-rolled and cold-rolled. [0003] The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm. Sheets are classified by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron sheets, etc.; by ...

Problems solved by technology

[0004] During the production process of the steel plate, due to the effects of various auxiliary production chemical reagents added in the production process, the surface of the steel plate usually contains a lot of oil stains after the production is completed. At the same time, due to the cutting and grinding process in the production process, many small Small particles with magnetic impurities are adsorbed on its surface, and under the action of oil stain adhesion, it is difficult to clean the two on the steel plate, and the cleaning efficiency is low, especially for steel plates with many gaps on the surface, cleaning More difficult and less efficient
