Abstract：In recent years, the burden structure of 3 200 m3 blast furnace in Tangshan Steel has changed. The content of Al2O3 in slag is up to 16%, that has affected the performance of slag, and influenced the stability of production. By detecting the composition and performance of the slag and integrated with phase diagram theory, the effects of the Al2O3, R2 and MgO style on the properties of slag was analyzed. The results show that the R2 is under 1.15, the slag at lower temperatures have better liquidity;R2 is 1.2, the content of MgO style should be lower than 8.69%. The about 15%content of Al2O3, the 6%-9%content of MgO style, and the type slag R2≯1.2 chosen in Tanggang blast furnace is more appropriate.
