The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.
