高炉冶炼中悬料的产生往往是炉况失常的严重表现形式之一.处理及时恰当,对整个冶炼过程影响较小,处理不及时或不恰当,则有可能造成炉缸冻结之类的大事故;因此对产生悬料前的征兆及处理方法十分重视.随悬料产生的部位不同,表现的征兆及处理方法亦不同.一般说来,上部悬料往往是由于气一固逆向流分布失调所致,其中固相的分布主要是指矿石的分布,一般处理比较容易,如人工坐料是比较凑效的;下部悬料,则由于有液相的存在,往往因为不能对症下药进行处理,反而导致炉况进一步恶化.虽然很多工厂根据自己的实践,总结出了一些行之有效的处理办法,但由于对下部悬料机理认识还不十分清楚,还不能得出普 Blast furnace smelting in the production is often suspended furnace is one of the serious manifestations of furnace failure.Processing timely and appropriate, the impact of the entire smelting process is small, not timely or inappropriate treatment, it may cause the hearth to freeze such a big accident ; Therefore, before the phenomenon of hanging material and the handling of the attaches great importance.With the different parts of the suspension, the signs of performance and treatment are also different.In general, the upper suspension is often due to gas-solid reverse flow distribution disorders The distribution of the solid phase mainly refers to the distribution of ore, the general treatment is relatively easy, such as artificial sitting material is more effective; the lower suspension material, because of the existence of the liquid phase, often because of the right medicine can not be processed, but lead to Furnace conditions further deterioration.Although many factories according to their own practice, summed up some effective ways to deal with, but because of the understanding of the lower hanging material mechanism is not yet very clear, can not be reached
