渣口工作是炉前操作的重要环节。勤放渣、放好渣,放尽渣,做到安全生产,这有利于保证炉况顺行和强化冶炼。我厂84M~3高炉原渣口塞以园钢作塞杆,在杆端,有一铸铁塞头构成。这种渣口堵耙在使用时,其铸铁塞头顶端涂上耐火泥,并用人力堵口,故劳动强度较大,安全程度差,且当炉渣碱度较高或出现炉缸堆积时,渣口操作更显得繁重。针对这种情况,学习兄弟厂先进经验,采用了空气渣口堵耙。空气渣口堵耙,以(?)1铁管为塞杆,杆端用一中间钻有(?)8%孔的铸铁塞头,用软
The slag mouth work is an important part of the furnace operation. Ground residue, put slag, let slag, safe production, which is conducive to ensuring the furnace conditions and strengthen smelting. I plant 84M ~ 3 blast furnace slag to Park Steel for the stopper rod in the rod end, there is a cast iron stopper composition. This slag mouth block rake in use, the top of the cast iron plug coated with refractory mud, and human plug, it is labor-intensive, poor security, and when the slag basicity is higher or when the accumulation of hearth, the slag Mouth operation even more heavy. In view of this situation, learning advanced experience brother plant, using the air slag mouth block rake. Air slag mouth block rake to (?) 1 iron pipe as the rod, the rod end with a central (?) 8% hole cast iron plug, with a soft
