摘　　要：为了提高废钢比,降低转炉铁水消耗,解决炼钢产能大于炼铁产能的现状,马钢70 t转炉通过提高入炉铁水温度,少渣冶炼,降低出钢温度,利用铁块进行温度补偿,优化组织生产减少钢液在钢包中的温降,优化转炉供氧制度,溅渣护炉工艺等措施,使得铁水消耗从869 kg/t降到834 kg/t,铁水消耗降低明显并实现了稳产。In order to raise scrap ratio to reduce hot iron consumption and to solve the problem matching of the productivity between the steel making and iron making,taking of raising melting temperature,little slag smelting,lowering tapping temperature,compensating temperature by pig iron,realizing organization optimization to reduce the temperature drop,optimization of oxygen supply system and slag splashing technology,The practice shows that the hot iron consumption decreased from 869kg/t to 834kg/t with remarkable effect and Carrying out the stable produce.
