凌源钢铁公司炼铁厂3号高炉(360m~3)是凌钢“七五”改扩建三大主体工程之一。该工程于1986年底破土动工,经过一年多的紧张施工、于1988年3月6日晚点火开炉,3月7日下午顺利流出了第一炉铁水,炉况十分顺行、渣铁流动性能良好。该高炉原设计的炉料结构为高碱度烧结矿与酸性球团矿搭配使用。但由于与高炉配套的24m~2烧结机未能同步建成,此次高炉开炉使用了100%竖炉球团矿。3号高炉开
Lingyuan Iron and Steel Company Ironworks blast furnace No. 3 (360m ~ 3) is Lingang “seven five” reconstruction and expansion of one of the three main projects. The project broke ground at the end of 1986 and after more than a year of intense construction, it started to fire on the evening of March 6, 1988 and smoothly out of the first furnace hot metal on the afternoon of March 7. The furnace was very smooth and the flow of slag and iron Good performance. The original structure of the blast furnace charge structure for the high alkalinity sinter and acid pellets with use. However, due to the blast furnace supporting the 24m ~ 2 sintering machine can not be completed simultaneously, the blast furnace used 100% shaft furnace pellets. No. 3 blast furnace open
