Abstract：The COREX process has many advantages, such as the less pollution, the lower energy consumption and the lower dependence on the metallurgical coke, while it still has the disadvantage of the high sulfur level in the hot metal.To improve the desulfurization efficiency in the COREX3000 process, several aspects are studied and practiced.The work focuses on the effects of chemical compositions of slag, such as w(CaO)/w(SiO2)、w(MgO) and w(MgO)/w(Al2O3) on the desulfurization efficiency. The influences of chemical compositions of slag on the desulfurization efficiency and the sulfur distribution ratio are studied through experimental studies, and the optimal chemical compositions of the slag are listed. Comparing the effects of two kinds of basic oxides on the desulfurization efficiency, the binary basicity of slag should be preferentially adjusted within 1.201.35, and then w(MgO) of slag should be controlled. It is also necessary to take care of the appropriate w(MgO)/w(Al2O3) at about 0.800.90.
