一、原理由于对熔炼坩埚已有可能作肉眼直观,FeSi工艺的原理无疑地有了一个飞跃。图1为熔炼坩埚示意图。电极头周围是一个大空腔,空腔上部是一个软顶,它不断地熔化,粘稠物往下滴着或徐徐淌着。电极头和坩埚壁的温度经测定约达2000℃。从顶部滴下的物料落到金属熔池底部,在此便处于电极底下电弧产生的高温之中。此高温促 First, the principle As the melting crucible has been possible for the naked eye and intuitive, the principle of FeSi has undoubtedly had a leap. Figure 1 is a schematic view of the melting crucible. Around the tip is a large cavity, the top of the cavity is a soft top, it continues to melt, sticky drops dripping or dripping slowly. The temperature of the electrode tip and crucible walls was measured to be about 2000 ° C. The material dropped from the top falls to the bottom of the metal bath, where it is exposed to the heat generated by the arc below the electrode. This high temperature to promote
