汉阳钢铁厂用20T/小时的冷风化铁炉配6吨顶吹氧转炉炼钢,以外购生铁为原料,为降低钢锭成本自1976年起对化铁炉进行了以吃废钢(特别是吃车刨屑)的技术改造,经五年多的时间,在设备和工艺方面摸索了一套比较完整的经验,即以热风碱性化铁炉(热风温度350—450℃,炉渣碱度1.25—1.5)代替冷风化铁炉,五年来炼钢廿余万吨,总的废钢比达72.25％,当废钢比超过60％时,其
Hanyang Iron and Steel Plant with 20T / hour of cold weathering iron furnace with 6 tons of top-blowing oxygen converter steelmaking, purchased from the pig iron as raw material, to reduce the cost of steel ingots from 1976 onwards to eat scrap (especially to eat the car Shavings) technological transformation, after more than five years, in equipment and technology to explore a set of more complete experience, that is hot air alkaline iron furnace (hot air temperature 350-450 ℃, slag basicity 1.25-1.5 ) Instead of cold weathering furnace, five years of steel 200,000 tons, the total scrap ratio of 72.25%, when the scrap ratio exceeds 60%, its
