作为脱氧剂加到钢里去的锰,它的氧化是在钢水和炉渣的交界处进行的。氧化的强弱决定于:以每炉单位重量来计算的,钢水和炉渣接触面的大小。就平炉来讲,氧化的强弱,以钢水炉渣的接触面(炉底面积),和炉料重量的比例来表示。我们工厂里,平炉的这个数字很高,连到0.6M~2/T,这说明浇注装置的载重量不足;浇注装置的载重量,限制着炉料重量增加的可能性。因此,以锰铁形式加进炉里去的锰,就起了更加强烈的氧化作用。为了减少锰的烧损,也就是降低锰铁的消耗,著
Manganese, added to the steel as a deoxidizer, is oxidized at the interface between the molten steel and the slag. The strength of oxidation is determined by the size of the contact surface between the molten steel and the slag, calculated as unit weight per furnace. In terms of open hearth, the strength of oxidation, molten slag slag contact surface (floor area), and the weight of the charge ratio to represent. In our factory, the number of open hearths is very high, connecting to 0.6M ~ 2 / T, which indicates that the weight of the casting device is insufficient. The weight of the casting device limits the possibility of increasing the weight of the charge. As a result, manganese added to the furnace as ferromanganese acts more strongly. In order to reduce the burning of manganese, which is to reduce the consumption of ferromanganese
