Based on the different properties and phase analysis of vanadium slag and steel slag,it was suggested that the temperature,viscosity,basicity,CaO and MgO contents of vanadium slag were quite different from those of steel slag,and the lining maintenance technology of steel converter could not be completely applied to vanadium extraction converter.The main factors affecting the damage of lining resistant material of vanadium converter are analyzed.The smelting process,smelting cycle,working environment,slag composition and phase composition of vanadium converter are quite different from those of steel converter.It is pointed out that the maintenance of the lining of vanadium converter should be based on the damage causes and the characteristics of vanadium slag,and the technology of splash-slag protection after comprehensive building,slag repair and modification of vanadium slag can greatly improve the lining life of vanadium converter.
