At the present of the material and fuel,in order to keep good fluidity and high desulfurization capacity of the slag of 380m³ blast furnace of YIGANG,the article described the influence of the contents of MgO,Al2O3 and basicity on the melting temperature and fluidity of the blast furnace slag based on the four main contents(CaO,SiO2,MgO,Al2O3) of the slag.The result shows that the Ca0/SiO2 in the slag should be controlled between 1.1-1.2 and the temperature of slag be not lower than 1450 °C.
