提高高炉生产率和降低焦比的潜力法国顿刻尔克公司针对现代高炉炼铁的特点，对高炉下部的热平衡进行了大量的分析和试验，提出了通过使用金属铁和富氧大喷吹，使高炉下部的熔损反应减弱，降低焦比，提高生产率这一新观点。理论依据是：高炉下部所需热能的主要组成是熔解损... Improve the productivity of the blast furnace and reduce the coke ratio potential France Duke Ke Erke company for the characteristics of modern blast furnace ironmaking, the heat balance of the lower part of the blast furnace carried out a large number of analysis and testing, proposed by using metal iron and oxygen-rich large injection, so that The lower part of the blast furnace melt loss reaction weakened, reducing coke ratio, increase productivity of this new point of view. The rationale is that the main component of the heat required for the lower part of the blast furnace is the melting loss ...
