水岛铁合金公司建设的锰铁竖炉(简称SF)于1985年6月24日投产。该炉炉容398米~3,日产高碳锰铁270吨。锰铁竖炉操作和炼铁高炉不同,其焦比、炉尘和炉顶煤气温度都高。该炉采用中心装料万向节式无料钟炉顶(即CTBL)和热风辐射式换热器。炉体强化冷却,炉喉耐磨钢砖板和无料钟炉顶旅转机构均用水冷,还扩充了煤气净化系统。
The Ferromanganese shaft furnace (SF) constructed by Mizushima Ferroalloy Company was put into operation on June 24, 1985. The furnace capacity of 398 meters ~ 3, Nissan 270 tons of high-carbon ferromanganese. Ferromanganese shaft furnace operation and blast furnace iron different, the coke ratio, furnace dust and top gas temperature are high. The furnace is equipped with a center-mounted universal joint bell-less top (CTBL) and a hot-air radiant heat exchanger. Furnace body to strengthen the cooling, throat wear-resistant steel plate and the bell-free roof travel agencies are water-cooled, but also expanded the gas purification system.
