摘要
太钢二炼钢在80t转炉上采用直接还原铁代替专用废钢冶炼品种钢的试验并推广使用，结果表明，直接还原铁代替废钢合适的比例为35％～50％，使用部分直接还原铁后转炉脱磷能力增加，脱磷率提高2．4％；80t转炉配加5t直接还原铁，石灰消耗增加9．3kg／t；使用直接还原铁代替部分专用废钢，钢中残余元素及有害元素含量都很低。
Experiment and application of the direct reduced iron in refining the steel grades in converter instead of the scrap has been carried out in an 80 t Converter in the 2^nd Steel-making Plant of Taigang. Results indicates that the reasonable proportion of the DRI in replacement of scrap is 35% - 50%. By using part of the dirct reduced iron the dephosphorization ability of the converter has been raised by 2.4%. For an 80 t converter, charge of 5 t direct reduced iron will increase consumption of 9.3 kg/t lime. Results also shows that by adoption of the new process the residual elements and harmful elements are rarely seen.
