Abstract

The invention relates to a steel smelting converter steel slag treatment micro-powder extraction and separation process, in particular to a steel smelting converter steel slag treatment micro-powder extraction and separation device which comprises a supporting base, a bearing disc, a magnetic separation assembly, an ejector rod assembly, a rotary material supporting mechanism and a rotary drivingmechanism. The magnetic separation assembly comprises a cylinder supporting base and three electromagnetic discs, the ejector rod assembly comprises a fixing shaft, a rotor wing plate, two ejector rodpieces and two springs, and the rotary material supporting mechanism comprises a center rotary drum, four material supporting discs and four tension springs. The device provided by the invention adopts a dry magnetic separation and extraction mode, can realize separation and extraction of the metal iron powder in the steel slag micro-powder, is simple in structure, can reduce expenditure and investment of water and electricity in the production and treatment process, and avoids waste of the separated metal iron powder.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, and specifically proposes a process for extracting and separating micropowder from steel smelting converter slag treatment. Background technique [0002] Converter steel slag is a by-product of the converter smelting process. It is a solid waste that accounts for about 10% of the steel output. Iron, long-term stacking of converter steel slag in large quantities will not only occupy space, but also cause waste of resources due to the inability to effectively recycle metallic iron. Therefore, converter steel slag is often reprocessed. Crushing, screening and magnetic separation process, the metal iron powder obtained by sorting can be recycled, and the remaining waste residue can be used as raw materials or additives required for cement production and brick making. [0003] The steel slag powder obtained after fine crushing of converter steel slag generally needs to be separated by...
