Chaeng(Great wall Machinery)supply complete equipment for active lime production line. The active lime is widely used in steel production, Metal Mg production, Al2O3 production, calcium carbide and Power plant desulfurization paper production area.
1.Steelmaking practice certified that, the active lime can improve the desulfurization and dephosphorization efficiency of 80%, and shorten the smelting time. It can be completely take reaction with acidic substances in the molten steel in 3-5 minutes.
2.Desulfurization and dephosphorization efficiency of active lime is obviously increased, the average removal rate of steel is 34.5% ,especially for high iron, efficiency is more obvious, and the removal agent consumption can be reduced by about 45%.
3.Steelmaking with active lime iron material consumption can be reduced by 5-15Kg/t steel than non-active lime. And it also can reduce the steel splash and adhesion on oxygen lance;
4. Lime consumption decreased: steelmaking with active lime, the consumption can reduce 20~25Kg/t steel,compared with non-active lime.
5.Steelmaking with active lime, slagging is fast, desulfurization, dephosphorization ability is significant, the production efficiency can be improved by 5%~10%. 6.Quality requirement of the active lime limestone:CaO≥52% SiO2≮2.0% MgO≮1.5%
