quantity of scrap charged to BOF converter(These methods for increasing the quantity of scrap charged to the BOF converter include the preheating of scrap, the combustion of carbonaceous fuels, the oxidation of aluminum scrap, and CO post combustion. 这些增加氧气顶吹转炉废钢加人量的方法包括废钢预热、碳质燃料燃烧、废铝氧化以及一氧化碳二次燃烧等。)
charging amount of coke(What is more, owing to the increase in the injection amount of pulverized coal, the ore/coke ratio of furnace burden has increased, resulting in a relative decrease in the charging amount of coke. 此外，由于粉煤喷吹量增加。炉料的矿焦比也已经增加，从而导致焦炭人炉数量相对下降。)
total energy input to the EAF(It is now common for 30-40% of the total energy input to the EAF to come from oxy-fuel burners and oxygen lancing. 现在氧-燃烧嘴配合氧枪吹氧所提供的能量通常占电弧炉总能量输人的30% ~ 40%。)
