液压锤用于破碎钢厂的渣壳,是最困难的应用之一,而Krupp HM2500型液压锤可以很好地完成这一工作。 渣壳是10～20t钢水包内的结壳,由炼钢车间堆积的炉渣组成。这些渣壳组成成分变化很大,而且还取决于多少生铁从漂浮着炉渣的钢水上面撇取出来。当生铁含量达60～70％,还值得再进行冶炼。生铁比炉渣重,沉淀于钢水包的底部,在重新熔炼之前,必须把炉渣从钢水包表面拆下来,这些破碎的炉渣还可用作建筑材料。 过去,这一任务由装有锤头的挖掘机或渣壳破碎机完成。但渣壳碎块崩向四面八方,造成很大危险。
Hydraulic hammers are one of the most difficult applications for crushing the skull of a steel mill, and the Krupp HM2500 hammer can do the job well. The skull is a crust in a 10-20 t ladle consisting of slag accumulated in the steelmaking plant. These skull compositions vary widely and depend on how much of the pig iron is skimmed from the molten steel on which the slag floats. When the pig iron content of 60 to 70%, but also worth further smelting. The pig iron is heavier than the slag and settles on the bottom of the ladle. The slag must be removed from the surface of the ladle prior to remelting, and the crushed slag can also be used as a building material. In the past, this task was done with a hammer-equipped excavator or crusher. However, the debris crushed collapse in all directions, causing great danger.
