Abstract

The present invention relates to a process for extracting and separating micropowder from iron and steel smelting converter steel slag treatment, in particular to a device for extracting and separating micropowder from iron and steel smelting converter steel slag treatment, comprising a support base, a bearing tray, a magnetic separation assembly, a push rod assembly, a rotating support mechanism and Rotary drive mechanism; the magnetic separation assembly includes a cylindrical support seat and three electromagnet disks, the ejector rod assembly includes a fixed shaft, a rotor plate, two ejector rod parts and two springs, and the rotary material supporting mechanism includes a center Drum, four trays and four tension springs; the device provided by the invention adopts the separation and extraction method of dry magnetic separation, which can realize the separation and extraction of metal iron powder in steel slag fine powder, and has a simple structure, which can be used in production In the process of treatment, the expenditure on water and electricity costs is saved, and the waste of separated metal iron powder is avoided.

Description

Technical field [0001] The present invention relates to the field of iron and steel smelting technology, specifically proposed a steel smelting converter steel slag treatment micronized powder extraction and separation process. Background [0002] Converter steel slag is a by-product of the converter smelting process, is a solid waste, accounting for about 10% of steel production, converter steelmaking process, due to slagging formed by the melting slag slag has a certain viscosity and wrapped part of the metal iron, for the converter steel slag for a long time a large number of stacking will not only occupy the site, but also because can not effectively recover the metal iron and cause waste of resources, so often the converter steel slag for reprocessing, converter slag in the treatment process generally through rough breaking, fine breaking, Sieving and magnetic separation of several major processes, the sorted metal iron powder can be recycled, and the remaining waste residue...
