前言高炉的软化带和熔融带,通常都被认为是炼铁过程中很重要的区域,但遗憾的是,由于人们对高炉操作的内部实际状况进行观测有困难,因此,直到最近,人们对该区域的情况所知甚微。七十年代,日本将好几个高炉快速冷凝下来,再进行解剖,他们得到了大量有关高炉内部状况的资料,这 Foreword The softening and melting zones of blast furnaces are generally considered to be important areas in the ironmaking process, but unfortunately it has been difficult to observe the actual internal conditions of blast furnace operations until recently The situation in the area is poorly understood. In the 1970s, Japan rapidly condensed several blast furnaces and then dissected them. They got a lot of information about the internal condition of the blast furnace, which
