| met. | enthalpy requirement to melt scrap steel | 熔化废钢的焓需求量 (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。) |
