Active Lime Production Line
Jiangsu Pengfei Group specially focused on developing and manufacturing of large-scale rotary kiln and ball mill, and we have comprehensive ability to supply the best service on turn-key basis with complete equipments, designing, installation and debugging of new type dry process cement production line with daily capacity under 10,000tons as well as the active lime production line with daily capacity under 1200tons. Active lime is widely used in steel industry, alumina industry, magnesium metal industry, calcium carbide industry, power plant desulfurization paper industry. While active lime is important auxiliary material for steel-making which could improve quality of molten steel, raise output, cut down consumption and cost and enhance the stability of operation.
Proved by practicing, the enterprises who utilizing active lime for steel-making have gained obvious economic benefits. During last 10 years, steel output has increased 40% by utilizing lime, however the percent that high-level lime with over 300ml activity accounts for the whole lime for steel making increased from 27% to 29.5% which only increased 2.5%.
1. According to steel-making, active lime could improve the efficiency of desulfurization and dephosphorization as 80% meanwhile it could shorten the smelting time. In 3~5 minutes, it could finish the adequate reaction with acid matter in molten steel but the lime reaction time of vertical kiln should be at least 6-10 minutes. Others it could increase over 40% furnace ridge and furnace material consumption could decrease 5-8kg per ton steel, so if we calculated as 10 million tons, it could save 15million tons each year, thus the benefits is obvious.
2. The desulfurization and dephosphorization efficiency of active lime obviously increases, average desulfurization ratio of steel-making could reach 34.5%, the effect is especially obvious for molten steel with hight-level S （S≥0.06%）, while the consumption of desulfurizer could decrease about 45%.
3、Utilizing active lime could cut down 5-15kg steel material consumption for each ton steel; reduce the molten steel splashing and gluing oxygen lance furnace mouth & fluepipe compared to using unreative lime.
4. Lime consumption decreases：Utilizing active lime could cut down 20-25kg steel material consumption for each ton steel compared to using uncreative lime, however using unreactive lime, lime consumption on each ton steel is not less than 65-70kg, while active lime is only 40-41.5kg.
5. Active lime quicken steel-making and slag-making, the capacity of desulfurization and dephosphorization is obvious, manufacturing efficiency could increase 5%-10%.
