| Message: | 600 tons of active lime production line equipmentDescription: We, Jiangsu Pengfei Group Co., Ltd supply complete equipments for active lime production line with capacity below 1200 ton per day. The active lime is widely used in steel production, Al2O3 production, Metal Mg production, calcium carbide and Power plant desulfurization paper production area. Active lime is an important auxiliary material in steel making industry. The using of active lime enhances the quality and capacity and lower down the loss and cost. It also stabilizes the operation. As proved in production, the using of active lime in steel making industry is very profitable. Recently years, the capacity of steel industry used lime increased by 40%. High quality lime with activity above 300ml increased from 27% to 29.5%.Explain1.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.The lime reaction time of shaft kiln need 6-10 minutes at least.And it also improve furnace ridge above 40%. The furnace burden consumption is reduced to 5-8Kg/t steel,calculated in 10000000tons,savings annual about 15000000,production efficiency is significant.2.Desulfurization and dephosphorization efficiency of active lime is obviously improved,the average S removal rate of steel is 34.5% ,especially for high S iron (S ≥ 0.06%), efficiency is more obvious, and the S 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;sticky mouth;flue sticking phenomenon.4.Lime consumption decreased: steelmaking with active lime, the consumption can reduce 20~25Kg/t steel,compared with non-active lime.And if use non-active lime,consumption is more than 65~70Kg,if us......url:http://www.cncementmachinery.com |
