武钢现有四座大型高炉,其容积各不相同:1号高炉为1386米~3;2号高炉为1436米~3;3号高炉为1513米~3;4号高炉为2516米~3。但炉顶装料设备均为马基式,不过在结构尺寸上有所差异,1号2号3号高炉为φ4800毫米,四号高炉为φ6200毫米。近来高炉生产采用高压、大风量操作,对于强化高炉冶炼,提高产量,降低焦比和生铁成本起了重要的作用,然而由于炉顶压力提高,加速了煤气流对料钟和漏斗接触面的冲刷,给密封带来了很大的困难,炉顶装料设备损坏严重,设备寿命大大缩短,一般为8～12个月。因此,检修频繁,为了满足生产要求,
There are four large blast furnaces in WISCO with different capacities: 1 # blast furnace is 1386m ~ 3; # 2 blast furnace is 1436m ~ 3; # 3 blast furnace is 1513m ~ 3; # 4 blast furnace is 2516m ~ 3. However, the top charging equipment are all based on the Markov type, but the structural dimensions are different. The No. 1 No. 2 No. 3 blast furnace is φ 4800 mm and the No. 4 blast furnace φ 6200 mm. Recently, blast furnace production with high pressure, high volume air operation, for strengthening the blast furnace smelting, increase production, reduce coke and pig iron costs played an important role, however, due to the roof pressure increases, accelerated gas flow on the bell and funnel contact surface erosion , Brought a great deal of difficulty to the seal, the top charging equipment is damaged seriously, the life span of the equipment is greatly shortened, generally 8 to 12 months. Therefore, frequent maintenance, in order to meet production requirements,
