我厂两座高炉生产,由于各方面原因,1995年4号高炉结瘤严重,一年中打炉瘤六次,休风227.45小时。1996年1号高炉结瘤也同样严重,共打炉瘤六次,休风211.52小时。两年来由于休风多,炉况不顺,炼铁技术指标一直落后,本文就两年高炉结瘤进行剖析。 1.高炉结瘤的成因 4号高炉的结瘤主要是炉身以上属于碳瘤,灰质瘤。其生成的原因与原料结构有很大关系。使用磁铁机的渣铁(炉渣破碎后经磁铁机选出含铁炉渣),而且渣铁堆放时间长,
I plant two blast furnace production, due to various reasons, in 1995 No. 4 blast furnace nodules serious, a year in the stove to burn six times, rest 227.45 hours. In 1996 No. 1 blast furnace nodules are equally serious, a total of six times to fight stove tumor, rest 211.52 hours. In the past two years, due to more wind breaks and poor furnace conditions, the technical indicators of ironmaking have been lagging behind. In this paper, two years of blast furnace nodules were analyzed. The causes of blast furnace nodules No.4 blast furnace nodules are mainly above the body of carbon tumors, gray matter tumors. The reason for its formation and raw material structure has a great relationship. The use of magnet machine slag iron (slag crushed by the magnet machine selected ferrous slag), and slag iron stacked for a long time,
