在1100～1400℃,利用微波加热方式对转炉钢渣的碳热还原行为进行研究。结果表明,钢渣配加碳还原剂在微波场中可得到直径为10～20mm的Fe-C合金。碳当量越高,温度越高,粒度越小,保温时间越长,还原出的铁和磷含量越高。增加渣中SiO2含量也能有效改进还原效果。研究确定了微波场对还原反应的促进作用,在低温条件下实现了钢渣的还原脱磷,脱磷率最高可达到91.5%。
At 1100 ~ 1400 ℃, the carbon thermal reduction behavior of converter slag was studied by microwave heating. The results show that Fe-C alloy with diameter of 10 ~ 20mm can be obtained in the microwave field with steel slag and carbon reductant. The higher the carbon equivalent, the higher the temperature, the smaller the particle size, and the longer the holding time, the higher the iron and phosphorus content reduced. Increase the SiO2 content in the slag can also effectively improve the reduction effect. The reduction effect of the microwave field on the reduction reaction was confirmed, and the reductive dephosphorization of the steel slag was achieved under the condition of low temperature. The maximum dephosphorization rate reached 91.5%.
