Technology of removing magnetic powder from oil-containing steel plate with pores on surface

Abstract

The invention discloses a technology of removing magnetic powder from an oil-containing steel plate with pores on the surface, and belongs to the field of steel plate cleaning. According to the technology of removing the magnetic powder from the oil-containing steel plate with the pores on the surface, embedded brush balls with cleaning agents are laid on the surface of the steel plate and are heated, the lower parts of the embedded brush balls can be molten, the cleaning agents and powder absorption rolling balls inside the embedded brush balls fall off, and make contact with the surface of the steel plate together with extending brush bristles, the powder absorption rolling balls and the extending brush bristles move on the surface of the steel plate to generate a friction effect, and can extend into the pores in the surface of the steel plate under the action of the cooperation of bristle ball brushes, and therefore removal of oil stains in the pores in the surface of the steel plate can be remarkably improved, the magnetic powder in the pores of the steel plate can be effectively absorbed, and the oil stains and the magnetic powder are synchronously removed, and the oil and magnetic powder removal efficiency of the steel plate is remarkably improved; and the powder absorption rolling balls can store the absorbed magnetic powder, the magnetic powder is effectively preventedfrom adhering to the steel plate again, and therefore the overall oil and magnetic powder removal efficiency is effectively guaranteed.

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 ...

AI Technical Summary

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
