摘　　要：钢渣作水泥原料时,可替代全部的铁质原料和部分石灰石。由于钢渣中Al2O3的含量相对较低,采用16%的钢渣与石灰石选矿尾矿、硅石选矿废渣、粒化高炉矿渣等冶金选矿、冶炼废渣配料时,不需要大幅度提高Fe2O3的含量就可以降低熟料中C3A的含量,使抗硫酸盐硅酸盐水泥熟料的生料配料不再是一件难事。多种废渣配料后物料的易烧性改善,在干法回转窑上通过适时调整煅烧操作参数,有效地解决了预热器的结皮、堵塞和回转窑的结球、结圈等生产技术问题。When steel slag as a cement raw material, can replace all iron raw material and part of limestone. Due to the relatively low content of Al2O3 in steel slag,16% of steel slag and limestone ore dressing tailings,silica ore dressing tailings, granulated blast furnace slag and other metallurgical ore dressing,smelting slag ingredients, do not need to raise the content of Fe2O3 can reduce of C3A content in the clinker, the resistance to sulfate of Portland cement clinker raw ingredients is no longer a difficult task.A variety of waste residue after the ingredients, materials easy to burn to improve,in the dry process rotary kiln by timely adjust calcining operation parameters,effectively solves the crust of preheater,block and rotary kiln production technology such as ball, circle the problems.
