测定了钒钛钢渣在不同组元含量条件下的熔化性温度及熔化区间。通过电子显微镜分析V、Ti在岩相中的含量 ,找出了钒钛钢渣与普通钢渣熔化规律差别的原因。提出了钒钛钢渣进行溅渣护炉的控制方向 The melting temperature and melting range of vanadium-titanium steel slag under different components were determined. The content of V and Ti in the lithofacies was analyzed by electron microscope, and the reasons for the difference in the melting rules of vanadium-titanium steel slag and ordinary steel slag were found out. Proposed vanadium titanium slag slag splashing furnace control direction
