渣沟过去一直是用沟泥修补,维修量较大,尤其是堵渣机下方,几乎每一、二天就得修补,渣沟在维修过程中,经常不能放渣,直接影响高炉的正常生产,是炉前工作的薄弱环节。 1974年10月,炼铁厂四号高炉,在水冷泥套的启发下制成了水冷渣沟套,并在四号高炉的高渣沟、低渣沟、渣沟流嘴、下渣流嘴等部位,进行了二、三个月的试验,基本上取得成功。从而减轻炉前工作的体力劳动、节约了原材料、改变了维修渣沟影响放渣的局面,给高炉顺利高产创造了条件,深受炉前同志们的欢迎。
Slag ditch in the past has been used to repair Gou mud, a large amount of maintenance, especially clogging slag machine, almost every one or two days have to repair, slag ditch in the maintenance process, often can not put slag directly affect the normal production of the blast furnace, It is the weak link in front of the furnace. In 1974 October, the fourth blast furnace in the ironworks, under the inspiration of the water-cooled mud sets made of water-cooled slag ditch sets, and in the high slag ditch, low slag ditch, slag ditches mouth, slag dross mouth And other parts of the trial carried out two or three months, basically successful. Thereby reducing manual work before the stove, saving raw materials, changing the slag ditch affect the maintenance of the situation, to the smooth and high yield the blast created the conditions, by the furnace before the comrades welcome.
