Abstract More and more Australian iron ore had been consumed in Chongqing Iron and Steel Group Co., Ltd. in recent years and consequently the slag property had been changed, especially the increased value of Al2O3 in slag has defect on slag fluidity.The viscosity in CaO-SiO2-Al2O3-MgO-TiO2 slag that add chemical agents to industrial slags has been measured at different [R] and the mass percent of Al2O3, MgO, TiO2 were fixed at 12%, 8%, 5% respectively. In addition the slags viscosity at different cotent of TiO2 has been measured. The results show that moderate content of TiO2 can reduce viscosity, and viscosity decreasing with basicity increasing at current scope, the viscosity decreasing trend flattens when basicity exceed 1.35.
