鞍钢瓦房子锰矿50m~3锰铁高炉,经过5年的生产,炉壳破损严重,已到大修期。今年3月29～30日停炉大修。这次大修采用了控料线加水停炉的方法,基本上达到预期的目的。其操作制度如下: 3月29日20时开始投放停炉料,负荷较轻,全风操作。装料制度为:KJJSH↓(即K—锰矿石550kg,J—焦炭500kg,SH—石灰170kg,白云石50kg),到30日3时除掉白云石,并将石灰的用量减到140kg,但炉 Anshan Iron and the tile house manganese ore 50m ~ 3 ferromanganese blast furnace, after 5 years of production, the furnace shell damaged severely, has been overhaul period. March 29 ~ March 30 shutdown overhaul. The overhaul of the control line with water to stop the method, basically to achieve the desired purpose. The operating system is as follows: March 29 starting at 20:00 shutdown charge, lighter load, the whole wind operation. Loading system: KJJSH ↓ (ie K-manganese ore 550kg, J-coke 500kg, SH-lime 170kg, dolomite 50kg), to remove the dolomite at 3:00 on the 30th, and the amount of lime reduced to 140kg, but furnace
