众所周知,MnO 的还原在碱性渣下有利,而 SiO_2的还原却需要酸性渣。那么对于硅、锰同时还原的最佳碱度值应是多少,同时渣中 Al_2O_3、MgO 又怎样影响硅、锰的还原,这是人们关心的问题,即所谓渣型问题。另外,为了获得合格的硅锰合金,考虑硅、锰的还原率,原料中的 Mn/Fe、SiO_2/MnO 之比值多少合适,上述两方面可归结为一个问题,就是硅锰合金的配料问题。
It is well known that the reduction of MnO is advantageous under alkaline slag, whereas the reduction of SiO 2 requires acidic slag. So for silicon, manganese should be the same time the best reduction of alkalinity should be how much, while the slag Al 2 O 3, MgO and how to affect the reduction of silicon and manganese, which is a matter of concern, the so-called slag type problem. In addition, in order to obtain a qualified Si-Mn alloy, considering the reduction rates of silicon and manganese, the ratios of Mn / Fe and SiO 2 / MnO in the raw materials are appropriate, the above two problems can be attributed to the problem of the ingredients of the Si-Mn alloy.
