撇渣器工作好坏直接影响高炉的正常生产。我厂从1969年开始一直沿用人工捣打炭素撇渣器。使用这种撇渣器,每出一次铁,放小井铁一次,同时用炮泥和河砂补修一次,每周要修砌三次。有时因撇渣器未烤干引起打炮;或因捣打不实容易冲垮。捣打炭素撇渣器不仅劳动强度大,工作条件恶劣,而且很不安全。撇渣器出事故还常影响正常出铁。1985年7月5日我厂利用1号高炉检修机会,用自焙炭砖修砌撇渣器。经过几次放小井铁水试验,观察内衬完整无损,使用两个月后内衬仍无损坏。因效果好,推广到2,3,4号高炉上使用,至今已近一年。1.自焙炭砖与粘结剂材质见(表1、表2) Skimmer works directly affect the normal production of the blast furnace. I plant from 1969 has been using manual ramming carbon skimmer. Use this skimmer, once each iron, put a small iron shaft, at the same time with mud and river sand repair time, to repair three times a week. Sometimes due to skimmer did not roast dry caused by fire; or ramming false real easily washed down. Ramming carbon skimmer is not only labor-intensive, poor working conditions, but also very unsafe. Skimmer accidents often affect the normal iron. July 5, 1985 I plant the use of No. 1 blast furnace maintenance opportunities, with self-baking charcoal brick repair skimmer. After several small well iron hot water test, the liner was completely intact, and the liner was still intact after two months of use. Due to good effect, to promote the use of blast furnace 2,3,4, has been nearly a year. 1. Self-baking carbon brick and binder material see (Table 1, Table 2)
