摘　　要：以细粒级低磷转炉渣替代高磷转炉渣用于炼铁烧结熔剂生产迫在眉睫,可减轻炼钢脱磷压力。通过对比试验表明:细粒级低磷转炉渣中小于3mm占比接近78%,将会提高硅酸盐反应接触面积从而增加烧结活性。当低磷钢渣配比在2.0%时,湿筛混合料中1-3mm达到最高的50.87%,干筛混合料中达到最高的50.25%,转鼓强度达到最高的58.93%,烧结矿中Fe0和P含量较基准下降34.08%和20.97%。It is urgent to replace high phosphorus converter slag with fine-grained low phosphorus converter slag.Through comparative test,the proportion of less than 3 mm in low phosphorus steel slag is close to 78%,which will improve the sintering activity.When the ratio of low phosphorus steel slag is 2.0%,the highest content of 1-3mm in wet sieve mixture is 50.87%,the highest content of 50.25%in dry sieve mixture,the highest drum strength is 58.93%,and the Fe0 and P content in sinter is 34.08%and 20.97%lower than the benchmark.
