摘要
用熔滴实验装置研究了矿、焦层装及混装时矿石软熔层的透气性,发现混装时软熔层的透气性获得大幅度改善。获得改善的原因在于混装时软溶层的结构发生了质的变化。
The permeability in soft melting zone observed in the blast furnace charged with alternate layers of ore and Coke, and in that charged with mixed ore/coke, is studied using the molten drop testing apparatus.It is found that the permeability in soft melting zone is significantly improved with a mixed ore/coke charge.The improvement results from a change in the essential constitution of the soft melting zone when charged with an ore and coke mixture.
