摘要

摘要: 研究分析了電弧爐煉鋼過程的冶金學特征,指出供應能量對電弧爐煉鋼的物質轉化過程起到了決定性的作用.觀察、認識到在煉鋼過程中存在著微觀、介觀、單元操作級和工位級等尺度級的時空多尺度結構.在工位級按能量將供氧、供電兩項功率單元進行跨尺度集成,形成了工位級跨尺度能量集成的一般方法,并用數學公式進行了描述.工業試驗和工業生產表明:跨尺度集成的理念和方法與煉鋼生產相結合可取得較好的生產效果,平均冶煉電耗為271.1kW·h·t^-1,氧氣消耗為40.4m³·t^-1,冶煉周期為52.9min.

Abstract: Metallurgical characteristics in the electric arc furnace steelmaking process were analyzed.The result showed that energy supply played a decisive role on material transformation.On the basis of the realization of space-time multi-scale structures which contained microscale,mesoscale,unit operation and working operation scale,trans-scale integration on two units of oxygen supplying and power supplying was realized according to energy in working operation scale and a general method of energy integration was formed.Its mathematical and physical expressions could be described.Industrial test and industrial production indicated that great production efficiency was made in combination with the idea and method of trans-scale integration.The smelting electricity consumption was 271.1 kW·h·t^-1,the oxygen consumption 40.4 m³·t^-1,and the smelting period 52.9 min on average.
