| 摘 要： | 梅山炼钢厂对转炉钢渣主要采取滚筒渣处理工艺，经处理后渣颗粒度小于5 mm的比例在85%左右。滚 筒渣是一种预熔渣，其主要成分为CaO、SiO 2 、FeO，具有熔点低、碱度高、氧化性高等特点，将滚筒渣作为造渣剂可 促进转炉冶炼前期的化渣速度，提高炉渣碱度和氧化性，降低冶炼成本。梅钢在滚筒渣回收利用方面进行了有效 探索，实践表明:使用滚筒渣后，吨钢石灰消耗降低6.5 kg/t，终渣碱度提高0.3，磷分配比提高5.3且波动范围变 窄，钢铁料消耗降低4.6 kg/t。

| Abstract: | Meishan Steelmaking Plant adopts BSSF technology to deal with BOF slag,after that the proportion of slag with granularity less than 5mm is about 85%.BSSF slag is a sort of pre-melting slag,which composition is CaO,SiO2,FeO,and has many characteristic such as low melting point,high alkalinity and high oxidability.BSSF slag used as slag-forming element can promote the slag melt rate of prior period,improve alkalinity and oxidation,lower cost.Meishan Steel has effectively explored recycle of BSSF.The practice ... |
