The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.

主要是因为铁滴穿过终渣时也发生+=Fe+CO 反应，此时渣中含量虽少，脱碳反应的动力学条件很好，具有较强的脱碳能力。
