Experimental results show that at 1500？C, the viscosity of CaO (55.8%)-Al<sub>2</sub>O<sub>3</sub> (20%)-SiO<sub>2</sub> (11.2%)-MgO (10%)-Li<sub>2</sub>O (3%) slag is lower than 0.3 Pa？s, having good flow properties; at 1600？C, under the condition of slag-metal ratio of 1:10, desulfurization rate of the slag can reach 77.14%, and sulfur content in steel decreases to 0.008%. Desulfurization rate can even reach to 80% with Li<sub>2</sub>O content increasing in slag after composition optimization.</span><span style=\"line-height:1.5;\"></span>
