Temperature characteristics research of Slag Dephosphorization by Microwave Field

利用微波碳热还原方法,对转炉钢渣脱磷进行实验,研究了钢渣的升温特性。结果表明,在温度越高、粒度越细小和碳当量越大时,微波处理钢渣的脱磷效果越好和钢渣升温特性越快;钢渣种类对脱磷效果也有明显的影响。从而,确定了微波处理钢渣的工艺参数。

With using of microwave carbon-thermal reduction method, to the converter slag dephosphorization experiment, it researches the characteristics of temperature increasing of steel slag. The results show that, in the higher temperature, the fineness smaller and the carbon equivalent larger, steel slag dephosphorization effect is better and the heating characteristics of steel slag is faster in microwave processing; slag types on steel slag dephosphorization has significant impact. Thus, process parameters are discussed and determined.
