高炉冶炼过程是在炉料不断下降和煤气流不断上升的相向运动中进行的,要维持高炉稳定、顺行,必须保证煤气有边沿与中心两条通路,也就是保持料柱有较好的透气性。在一定的原、燃料条件下,料柱透气性与高炉的操作制度有关。影响高炉行程的因素很多,判断炉况的手段也很多,我们在判断与处理炉况时,必须抓住炉内料柱透气性这个主要问题。外部条件与内部条件发生变化,最终都要在料柱透气性上反映出来。如原料粉末增加,炉内料柱透气性恶化;炉缸内渣铁没有出尽,也要严重地影响料柱透气性。所以,高炉操作的中心环节是控制炉 The blast furnace smelting process is carried out in the continuous movement of the charge and the rising gas flow. In order to maintain the stability of the blast furnace, it is necessary to ensure that the gas has two paths of the edge and the center, that is, the material column has better permeability . In a certain original, fuel conditions, column gas permeability and blast furnace operating system. Many factors affect the blast furnace trip, there are many ways to judge the furnace conditions, we judge and deal with furnace conditions, we must grasp the main problem of gas permeability furnace lining. Changes in external conditions and internal conditions, and ultimately should be reflected in the permeability of the material column. Such as the increase of raw powder, the furnace column gas permeability deteriorated; furnace slag iron slag is not exhausted, but also have a serious impact on column permeability. Therefore, the blast furnace operation is the central part of the control furnace
