冲天炉熔炼结束,打炉工作完成后,前炉中的一些残渣剩铁仍在向处于最低位置的出铁口缓缓地流动,最后凝结在出铁口内外,将出铁口堵塞,清理前炉时,清除残铁,费工费力,有时还会给出铁口留下隐患。为此可采用预埋木棒去解决。用比出铁口细一些的短木棒,前端制尖状,后端钉上木柄即可。打炉时,从出铁口放出剩余铁水及渣子,待流完时,随之将预埋木棒打入出铁口,并保留在其中,由未流完的残留渣,铁浆将其前 After the cupola furnace is melted and finished, the remaining iron in the forehearth is still flowing slowly to the taphole in the lowest position, finally condenses inside and outside the taphole, blocks the taphole, Furnace, remove the residual iron, laborious effort, and sometimes give the tipped left behind. This can be embedded wood stick to solve. Shorter than the tap hole with a short stick, the tip of the system to the tip, the back end of the nail on the wooden handle can be. When the stove is fired, the remaining molten iron and slag are discharged from the taphole. After the stream is finished, the embedded wooden sticks will be driven into the taphole and retained therein, leaving the residue
