高炉冶炼锰铁,炉渣中一般带锰铁损失约占产量的7—10%。故努力减少这部份锰的损失,具有很大的经济实效。我厂对锰渣带锰铁的原因,作了理论上的分析,从而就以下几个方面采取措施,减少锰渣带锰铁,提高锰的回收率: 1、选择合适的造渣制度和热制度即对炉渣要求具有较高的MgO,约在8%左右,和较低的MnO,约4%左右。要求锰铁[Si]量应控制在0.8~1.5%,则可保持炉缸有充沛热量,工作活跃;同时炉渣粘
Blast furnace smelting ferromanganese, slag generally with manganese loss of about 7-10% of the output. Therefore, efforts to reduce this part of the loss of manganese, with great economic effectiveness. I plant on the manganese slag with ferromanganese reasons, made a theoretical analysis, which in the following aspects to take measures to reduce manganese slag with ferromanganese, manganese recovery rate increased: 1, select the appropriate slagging system and heat The system requires that the slag have a higher MgO, about 8%, and a lower MnO, about 4%. Require the amount of ferromanganese [Si] should be controlled at 0.8 ~ 1.5%, you can keep the hearth with plenty of heat, active work; slag sticky
