Evaluation of metallurgical properties of blast furnace slag of JISCO and analysis of furnace condition
The good metallurgical properties of blast furnace slag are the conditions for stable and smooth running of blast furnaces.Aiming at the unsmooth furnace condition of blast furnaces of JISCO in recent years,the field sampling and the laboratory analysis for blast furnace slag were carried out.The results showed that the viscosity of the slag was below 0.5 Pa· s at 1 450 ℃,the distribution ratio of sulfur between slag and iron more than 32,and the alkali discharge rate about 110 ％.The metallurgical properties of the slag such as fluidity,stability and alkali discharge were good,which could meet the requirements of blast furnace smelting.Combined with the production practice of blast furnaces in JISCO,some improvement measures were put forward from the operating system such as charging,air supply and others.
