Description
Technical field
It the utility model is related to that a kind of slag is secondary to select iron system.
Background technology
Slag is one of main waste residue of iron and steel enterprise, and its discharge capacity is about the 15~20% of output of steel, the annual steel in China
Slag discharge capacity is more than 80,000,000 tons, if not handling and comprehensively utilizing, slag can take increasing soil, pollution environment,
Cause the waste of resource, influence the sustainable development of steel and iron industry.
Main mine is mutually dicalcium silicate or tricalcium silicate slag in slag, and the low slag of basicity contains olivine (CaO RO
SiO2), rhodonite (3CaO RO 2SiO2), RO phases, the high slag of basicity contain dicalcium silicate (2CaO SiO2) and silicic acid
DFP (3CaO SiO2).In convertor steelmaking process, part is wrapped because being a bit sticky the melting vessel slag tool that slag making is formed
The compositions such as metallic iron, FeO and Fe3O4；Metal abrasive grit and ferrous material distributed pole are uneven in slag, grain size number is fine, with
The embedding cloth close relation of silico-calcium matter solid solution, it is more difficult to monomer dissociation, slag to reach preferable separating effect must carry out it is levigate, with
Just magnetic separation is carried out after monomer dissociation again, preferably could so be separated irony composition in slag with other oxides.Due to steel
Slag toughness is big, fragility is poor, and contains certain metal abrasive grit, and not only difficult broken but also hardly possible mill, mill efficiency is low, power consumption is high, cost
Height, mill efficiency and metal recovery rate how are improved, reduce grinding pow consumption, directly affect the level of comprehensive utilization of steel slag resource.
At present, the domestic processing technology to slag is generally：The high-temperature fusion liquid sent from steelmaking converter by slag ladle
Slag, after being poured into slag stacking field, in cooling procedure of fetching water, slag efflorescence to below 250mm, the slag after efflorescence is using electricity
Disk selects high magnetic material, and high magnetic material uses the method for hand picking to sort as iron thallium steel and primary slag steel, electromagnetism again
The once low magnetic material that disk is selected uses shaking-sieving to select granularity as more than 80mm and below 80mm material, more than 80mm things
After expecting that below the 80mm materials obtained again with screening after below 80mm are crushed to using hammer mill to be mixed, one-level roller is sent to
Magnetic separator carry out magnetic separation, obtain high magnetic secondary slag steel and secondary low magnetic material, by the primary slag steel obtained in said process,
Secondary slag steel reinforced concrete is levigate using secondary ball mill progress after closing, and controls the following content of the non-mesh of granulated iron material granularity -200 in slag steel to account for
More than 80%, but abrasive grit keeps original granularity in slag steel, and ball milling material carries out magnetic separation using secondary magnetic wind joint iron dressing machine again, can
The granulated iron of converter producing needs is met, secondary low magnetic material is stored up as solid waste；As can be seen that current slag
This simply broken-screening-magnetic separation iron selection technique, because the slag granularity after hammer crushing crusher machine is big, iron-holder is low, ball
Time-consuming and it is big that ball mill is lost for honed journey, meanwhile, it is grain steel and steel slag tailings to sort rear product, granulated iron poor quality, tailings
Iron-holder it is higher, lack to the further iron selection technique of tailings, make steel slag resource using being restricted.
