冲天炉熔炼结束时,打开前炉出铁口清理前炉内残渣、残铁的过程中,往往残留部分的渣,铁留在出铁口内外,使出铁口完全堵死,以致在修整前炉时,为凿去残渣铁,不仅费工较多而且破坏了出铁口应有的形状。这样,增加了修炉操作,我厂采用了预埋木棒法解决了这个问题。预埋木棒法就是从引火木柴中找来比出铁口直径略小一些的木棒,将其前端碳化。在打炉时,俟出铁口放出剩余铁水后,不等渣子流出,随即将木棒打入出铁口,并保留在那里,由于有渣,铁将木棒前端全部包盖,尽管温度很高,但处于缺氧状态下的木棒只能碳化,而
Cupola smelting at the end, open the front furnace taphole cleaning before the furnace residue, residual iron in the process, often residual part of the slag, iron left in the taphole, the taphole completely blocked, so that before trimming When the furnace, to chisel to the residue of iron, not only more labor but also destroyed the shape of the taphole. In this way, an increase of furnace repair operation, I plant embedded wooden stick method to solve this problem. Buried wood stick method is from the firewood was found in the iron mouth slightly smaller than the diameter of the stick, the front carbonization. When the stove is tapped, the remaining molten iron is discharged from the taphole, and the dregs run out immediately. Then the dice are driven into the taphole and remain there. Due to the slag, the iron covers all the front ends of the sticks. Although the temperature is very high High, but in the hypoxic state of the stick can only be carbonized, and
