1. Steelmaking practice has proven that active lime can increase the desulfurization and dephosphorization efficiency by 80% and shorten the smelting time. It can completely react with the acidic substances in the molten steel within 3-5 minutes, while the reaction time of shaft kiln lime is at least 6-10 minutes. In addition, the furnace ridge is increased by more than 40%. The consumption of furnace charge has also been reduced by 5-8Kg/t steel. Calculated based on 10 million tons, the annual saving is about 15 million, and the production efficiency is significant.
2. The deS and P removal efficiency of active lime is significantly improved. The average deS removal rate in steelmaking reaches 34.5%, especially for high S molten iron (S≥0.06%). The efficiency is more obvious, and the consumption of deSulfurization agent can be reduced by about 45%.
3. When steelmaking uses active lime rather than inactive lime, the iron consumption can be reduced by 5-15Kg/t steel, and it can also reduce the splashing of molten steel and the sticking of oxygen lance, sticking to the furnace mouth and sticking to the flue.
4. Reduced unit consumption of lime: The unit consumption of active lime for steelmaking can be reduced by 20~25Kg/t steel compared with inactive lime. When using inactive lime, the consumption per ton of steel is not less than 65~70Kg, while using active lime is 40~41.5Kg. /tsteel.
5. Activated lime steelmaking can produce slag quickly, has significant desulfurization and dephosphorization capabilities, and can increase production efficiency by 5% to 10%.
Active Lime Production Line
It can provide complete sets of equipment and one-stop service for reaching production and standards for active lime production lines with a daily output of less than 1,200 tons. Activated lime is widely used in steel, alumina, magnesium metal, calcium carbide and power plant desulfurization and papermaking industries. Activated lime is an important auxiliary raw material for steelmaking. The use of activated lime has a series of characteristics such as improving the quality of molten steel, increasing output, reducing steelmaking consumption and costs, and stabilizing operations. Practice has proved that all enterprises that use active lime to make steel have achieved significant economic benefits.
