冲天炉熔化过程中应注意哪些安全问题? | 2012-3-6 16:44:00

冲天炉熔化过程中应注意哪些安全问题?

    冲天炉是应用最广泛的熔炼铸铁的熔炉,其主要操作过程为:修炉、生火、装料、送风、出铁、出渣、打炉等。下面就其操作过程介绍应注意的安全问题: 
    (1)修炉 冲天炉经使用后,炉壁很多地方被侵蚀变薄,如不及时修复,炉壁烧穿就会造成重大事故。修炉前应进风使炉膛温度下降后方可进炉,工人应穿戴好必要的防护用品,在加料口下面设置坚固的防护罩,以免物体落下伤及工人。加料口必须设度警告信号,以示炉内有人工作。修筑炉材时不准用手涂抹,以免造成伤害。 
    (2)生火 炉子修好后,最好让其自然阴干一段时间,使用前要烘干。烘干应用小火慢慢进行,如温度升得太快大高.容易使修补的炉壁发生开裂或烘不透现象,从而留下事故隐患。 
    (3)装料 装料多采用机械化,在装料机的上料路线附近应装设栏杆围住,以防加料操作时炉料落到工人身上。 
    (4)送风 炉料加好后,让炉料预热一段时间即可送风。送风前应打开1~2个风口,放出一氧化碳气体,然后再进行鼓风。 
    (5)出铁 在整个熔化过程中,炉内温度很高,为防止铁水溅出伤人,应将炉周围铁水槽中的残铁等杂物清除干净。必须等铁水包放稳后才可打开出铁口。 
    (6)出渣 应按规定的时间出渣,不可使渣漫至风口,以免发生事故。出渣口必须设置防护挡板,防止熔渣喷到工人身上。用水冷却炉渣时,要防止被水蒸汽烫伤。 
    (7)打炉 打炉是打开冲天炉底,放出残余的底料。打炉前应检查炉底下面及附近地面是否有水;打炉前应停风然后打开风口,并放尽铁水及炉渣;打炉前必须与有关方面联络好,并发出信号,使所有人员都离开危险区后方可打炉;打炉后须迅速将落下的炉料浇灭。
