借鉴各种已有合金的脱磷法对锰铁脱磷进行了比较系统的实验研究、探索和热力学基础分析,并在此基础上就锰铁的脱磷路线提出了自己的见解。实验和热力学分析表明,石灰渣系和苏打渣系的氧化脱磷对液体锰铁不能奏效,苏打和锰熔体还有激烈的相互作用。铁水中含锰超过约5％(石灰渣下)或约15～20％(苏打渣下),脱磷效率明显变坏。惰性气流中用
Drawing lessons from various dephosphorization methods of alloy, this paper systematically studied and explored the dephosphorization of ferromanganese, and based on the analysis of thermodynamics. On this basis, we put forward our own opinions on dephosphorization of ferromanganese. Experimental and thermodynamic analysis shows that the oxidative dephosphorization of the lime and soda slag systems does not work well with liquid ferromanganese and there is intense interaction between the soda and the manganese melt. More than about 5% of manganese in molten iron (lime slag) or about 15 ~ 20% (soda slag), dephosphorization efficiency significantly worsened. Used in inert gas flow
