Influence of High Al2O3 Slag on Operation of 3 200 m3 BF in Jinan Steel
WANG Jun
Abstract：To the characteristics of high Al2O3 slag with higher viscosity, poor liquidity, and poor desulphurization ability, by adjusting the thermal system and distributing system, the Mg/Al ratio in the slag is controlled lager than 0.6 by increasing the MgO content in sintering, the MgO content in the slag is made between 8%-11%, the overall operation of 3 200 m3 BF in Jinan Steel can fit smelting requirement with high Al2O3 slag. Under the condition of slag ratio increase by 43 kg/t, the silicon in the pig iron was decreased, the desulphurization ability of the slag was strengthened and third grade iron was eliminated basically.
