我厂炼钢炉渣及拆炉沥青白云石砖炼钢废弃物达30余万吨,大部已风化.其中废钢占5.6%.15mm以下渣粉的平均化学成分如表,类似于本厂烧结车间用的富矿粉、石灰石和白云石的混合成分.经本厂烧结杯试验及生产试验,15mm以下的渣粉以10～15%的配比用于烧结料,可以烧出品位为50%上下,碱度1.2左右的符合本厂技术标准的烧结矿.高炉试用这种烧结矿,粉矿由27.6%下降到21.9%.
I plant steelmaking slag and demolition furnace asphalt dolomite brick steelmaking waste up to 30 million tons, most of them have been weathered .Among them 5.6% .15mm below the average chemical composition of slag powder, such as table, similar to the factory sintering plant With the rich mineral powder, limestone and dolomite mixed ingredients.Through the trial sintering cup and production test, 15mm below the slag powder to 10-15% ratio for the sintering material, you can burn up and down the grade of 50% Alkalinity of about 1.2 in line with our technical standards sinter blast furnace trial of this sinter, ore fell from 27.6% to 21.9%.
