摘要/Abstract

摘要： 南钢100 t超高功率电弧炉的氧枪主要有炉门水冷碳氧枪及炉壁小氧枪,炉料为生铁+铁水40 t,废钢70 t,优化前总氧耗为43～45 m³/t。优化试验表明,生铁+铁水总量不变的情况下,针对不同铁水加入量,采用不同供氧制度,能够有效地提高氧气利用率,平均总氧耗降低至38 m³/t。

Abstract: Main oxygen lances of a 100 t UHP EAF at Nanjing Steel are door carbon oxygen lance and wall small oxygen lances, furnace charging consists of 40 t pig iron and hot metal and 70 t scrap, and total oxygen consumption before optimization of oxygen blowing procedure is 43~45 m³/t. Optimum test results showed that in condition with constant of the amount of (pig iron + hot metal), according to different charging amount of metal to adopt different oxygen supply rate, it was available to increase overall utilization of oxygen, the average total oxygen consumption decreased to 38 m³/t.
