目前,如何强化包钢高炉冶炼已成关键问题。为查明影响包钢高炉强化的基因和解决的途径,我们对包钢、首钢、鞍钢烧结矿的还原软化透气性进行了测定,初步查清了包头矿软熔透气性与首钢、鞍钢烧结矿的差别及其特性,并对现行的高炉配料和配加公益明矿以取代白云块矿进行了测定比较,结果表明,包钢烧结矿配加公益明矿是降低料层压损、提高料柱透气性的有效措施。
At present, how to strengthen the Baotou blast furnace smelting has become a key issue. In order to find out the genes that affect the strengthening of Baotou blast furnace and ways to solve them, we measured the reduction and softening air permeability of Baotou, Shougang, Anshan Iron ore sinter. The results showed that the soft gas permeability of Baotou ore is close to that of Shougang and Ansteel sinter The differences and characteristics of the blast furnace and the public beneficiation mine to replace the dolomite lump ore were measured and compared. The results show that the Baosteel sinter ore with Gongming mining is to reduce the pressure loss of the material layer and increase the material column Breathable and effective measures.
