摘要

通过专用转炉炉衬结构,延缓了熔池侵蚀速度;间歇式开氮气溅渣护炉提高了溅渣效果;铁块渣补技术节省了补炉料成本,优化了补炉效果;留渣操作节省了造渣料消耗,减缓了炉衬侵蚀;底吹动态模型促进了复吹效果,提高了金属收得率。复吹转炉炉衬维护集成技术降低了耐材、石灰、氧气、钢铁料等消耗,吨钢综合节省费用约1.62元。
        Through the special lining structure of converter, the erosion speed of molten pool is delayed. Intermittent blowing of nitrogen can improve the effect of slag splashing. The technology of iron block slag filling saves the cost of fettling material and optimizes the effect of repairing converter. The slag retention operation reduces the consumption of slag-forming material and slows down lining erosion. The dynamic model of bottom blowing promotes the effect of combined blowing and improves the metal yield.The integrated technology for lining maintenance of combined blown converter reduces the consumption of refractory material, lime,oxygen, steel and other materials, and saves about 1.62 Yuan per ton of steel.
