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。)
heat for melting scrap steel(A considerable amount of the heat for melting scrap steel is generated by the cracking of the volatile matter of coal into CO and H₂ and by their subsequent oxidation to CO₂ and H₂O. 大部分熔化废钢的热量是由煤的挥发分裂解成 CO 和 H₂， 随后又氧化成 CO₂ 和 H₂O 时放出的热量。)
enthalpy requirement to melt scrap steel(In both practices, 1000°C： is the maximum temperature of the scrap steel prior to charging the hot metal. Therefore, the enthalpy available for increasing scrap melting capacity is approximately 160 kcal/kg scrap input； while the total enthalpy requirement to melt scrap is 330 kca/kg scrap. 在这两种操作实践中，兑铁水前废钢的最高温度均为 1000°C。 因此，用于提高废钢熔炼能力的现有焓约为 160kcal/kg 废钢加入量，而熔化废钢的焓需求量总计为 330kcal/kg 废钢。)
dilute impurities in scrap(Nucor is also investing $60 million in an iron-carbide production facility on the island of Trinidad. This material will be used to supplement the scrap charge at its two plants in order to dilute impurities in the scrap to produce a better grade of steel. 纽柯钢公司目前还投资6 000万美元在特立尼达岛建造一套碳化铁生产设备。所生产的碳化铁将在其下属的两个分厂作为废钢铁的补充炉料，以便稀释废钢中的杂质，生产优质钢。)
