新城金矿选厂φ974×1 404炼金转炉的炉衬,投产初期采用分半捣打工艺捣筑。生产中发现,分半捣筑的炉衬不仅容易从牙槽结合处渗金造成金属流失,而且结合处缝隙易过早地熔蚀,缩短了炉衬寿命。另外,捣打工艺复杂(模具不易固定;牙槽结合处要求精度高,且装配时极易碰碎,捣筑和烘干周期长等)。为此,在生产实践中,通过各种不同耐 Metro gold mills φ974 × 1 404 alchemical converter lining, put into operation early half-ramming pound smash hit construction. Found in production, sub-pounding of the furnace lining is not only easy to infiltrate the alginate metal from the alveolar junction loss, but also easy to premature fusion of cracks, shorten the lining life. In addition, the ramming process is complex (not easy to mold fixed; alveolar junction with high precision, and easy to crush when assembled, pound construction and drying cycle length, etc.). To this end, in production practice, through a variety of different resistance
