一般说来,高炉每天出铁次数是根据每天装料批数及料批大小来确定的,也就是说,当高炉炉缸内的渣铁液面上升到一定高度时就必须出铁,否则炉缸内渣铁液面过高影响炉况稳定。这种确定高炉出铁次数的方法缺点是:由料批计算的渣铁量与实际渣铁量有误差,因而引起炉况波动。日本钢管公司确定高炉每天出铁次数的发明,是以炉底温度保持在一定值以下为目标,调整出铁次
In general, the daily number of blast furnace blasting is based on the number of batches of material and material batch size to determine, that is, when the blast furnace hearth slag level rises to a certain height when the iron must be, or furnace High level of slag and liquid in the cylinder affect the stability of the furnace. This method of determining the number of blast furnace tapping is disadvantageous: the amount of slag iron calculated from the material batch and the actual amount of iron slag error, which led to fluctuations in furnace conditions. Nippon Steel Tube Company to determine the number of times a day blast furnace invention, the bottom of the furnace temperature is maintained below a certain target, adjust the times out
