Magnetic separation equipment and magnetic separation method for steelmaking

Abstract

The invention relates to the technical field of magnetic separation devices, and particularly relates to a magnetic separation device and method for steelmaking. The invention aims to solve the technical problem of providing a magnetic separation device and method for steelmaking which are more thorough in magnetic separation of iron powder, easy to separate the iron powder from coarse particles wrapped on the iron powder and higher in purity of the iron powder. The magnetic separation device for steelmaking comprises an organism, a feeding hopper, a first installation plate, a second installation plate, a first electromagnet plate, a first transition plate, a first conveying mechanism, a scraping mechanism, a receiving machine, a coarse particle channel, a second conveying mechanism, a second electromagnet plate, a crushing mechanism, a dust collecting mechanism, a third conveying mechanism, an iron powder collecting mechanism, supporting legs and a second transition plate, wherein the bottom of the organism is fixedly connected with a plurality of supporting legs. The magnetic separation device achieves the effects of more thorough magnetic separation of the iron powder, easy separation of the iron powder from the coarse particles wrapped thereon, high purity of the iron powder and power saving.

Description

technical field [0001] The invention relates to the technical field of magnetic separation equipment, in particular to a magnetic separation equipment and a magnetic separation method for steelmaking. Background technique [0002] The coarse particles of sludge from converter steelmaking in iron and steel plants contain about 30% metallic iron, but at present, these coarse particles of steelmaking sludge are only used as steelmaking recycling materials and pellets, and the metallic iron contained therein cannot be used Effective use, there is a huge waste. [0003] In the prior art, when the iron in the coarse sludge particles is recovered, most of them directly use a magnetic separator to suck away the iron powder in it, so as to recover the metallic iron in the coarse sludge particles, but this kind of The method can only suck away the iron powder on the upper surface of the coarse sludge particles, but the iron powder buried in the bottom of the coarse sludge particles i...
