直接在高炉上进行矿石还元和成渣过程的研究是一件复杂而困难的工作.这种工作早在十九世纪中叶就已经开始了.当时所采用的方法是比较简陋的,主要是将矿石、熔剂和燃料混合装入一个有孔的铁箱中,用钢绳或铁链系住铁箱,然后放入炉内(古老的炼鉄炉),放入的深度要便于铁箱的取出.这种方法显然不能在近代的高炉上应用.廿世纪以来,在国外特别是在苏联,在这方面作了许多工作,目前苏联仍在继续进行这方面的工作,同时 The study of ore recovery and slagging directly on the blast furnace was a complex and difficult task that began as early as the middle of the nineteenth century when the method used was relatively simple and mainly consisted of Ore, flux, and fuel are mixed into a perforated iron box, tied to a steel box by a steel cord or a chain, and then placed in a furnace (ancient furnace) with a depth that allows removal of the iron box This method obviously can not be applied to the modern blast furnace.There have been many efforts made in this regard in foreign countries, especially in the Soviet Union since the 20th century, and the Soviet Union is still continuing its work in this field at the same time
