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。)
amount of flux to be added(The static charge model can calculate the amount of oxygen to be blown and the amount of fluxes to be added to attain the desired (aim) carbon and temperature for the heat. 为了取得该炉次的目标碳和目标温度，静态装料模型可以计算出需要的吹氧量和待加的熔剂量。)
