半个世纪以来,用氧气来改善冲天炉熔炼的效果,’已为许多人所证实,、但过去普遍采用把氧气简单地送入风管,使鼓人冲天炉的风富氧。这样的送、氧方法对提高铁水温度效果较差。七十年代初期,在能源危机的威胁下,英国铸铁研究协会加速了研究步伐,证明了风口喷氧和炉缸喷氧在提高铁水曝从袄度方面的效果比一般富氧送风显著得多。在送氧量占风量噢％的情况下,采

For half a century, the use of oxygen to improve the effect of cupola melting has been confirmed by many people. However, it was commonly used in the past to simply feed oxygen into the duct to enrich the wind that inspired the cupola. This send, oxygen method to improve the hot metal temperature less effective. In the early 1970s, under the threat of the energy crisis, the British Iron and Steel Research Institute accelerated its pace of research to prove that tuyere and oxygen injection from the hearth were significantly more effective than oxygen-enriched air supply in increasing iron exposure . Oxygen delivery in the amount of oxygen accounted for% of cases, mining
