五、吹炼操作中元素的氧化和还原铁的氧化:因为生铁中主要由铁元素粗成,所以根据质量作用定律,吹炼生铁时铁首先氧化,其反应为:Fe+1/2O_2=FeO;△H=-66713卡。此反应之发展决定了生铁化学损失量,以及使钢水充满着氧化铁,并依它来进行生铁中其它杂质之氧化。当吹风气流作用于露出渣子的钢水时,还发生直接以氧来氧化杂质的反应。但此种反应不会有限大的发展,杂质的氧化基本上依靠氧化铁中之氧。根据马克西莫夫之数据,铁之损失或渣子中氧化铁之含量取决于生铁中锰的含量。在图5关系中指
Fifth, the elements in the blowing operation of oxidation and reduction of iron oxidation: Because pig iron mainly by the rough elements of iron, so according to the law of quality, iron is first iron when blowing pig iron, the reaction is: Fe + 1 / 2O_2 = FeO ; △ H = -66713 card. The development of this reaction determines the amount of chemical loss of pig iron, as well as making the molten steel full of iron oxide and oxidation of other impurities in the pig iron according to it. When the blowing air flow acts on the molten steel exposing the slag, a reaction that directly oxidizes the impurities with oxygen also occurs. However, this reaction will not be limited to the development of oxidation of impurities is basically dependent on oxygen in iron oxide. According to Maximov’s data, the loss of iron or the content of iron oxide in the slag depends on the amount of manganese in the pig iron. In the relationship of Figure 5 middle finger
