摘要
基于冶炼时物质转化过程中的时空多尺度结构及其效应,研究了天津钢管公司150 t电弧炉炼钢工艺,以在工位级实现按能量将供氧和供电两项单元进行跨尺度集成,得到工位级跨尺度能量集成的数学模型。20炉四元炉料结构工况的工业试验表明,跨尺度集成的方法取得了较好的生产效果:平均出钢量141.2 t;冶炼电耗314.3 kWh/t;氧气消耗41.0 m^3/t,氧气利用率87.7%;金属收得率88.5%;冶炼周期49.5 min。
Based on space-time multi-scale structure during material transformation process in melting and its effects, the 150 t electric arc furnace steelmaking process at Tianjin Pipe Co has been studied to realize the trans-scale energy integration of two unit- electric power supplying and oxygen supplying at working-level and to get math model for trans-scale energy integration at working-level. The results of 20 heats commercial test with quarternary charge structure show that better production effect is got by using the trans-scale energy integration＇s method, i.e. average tapping liquid amount 141.2 t; electric power consumption for melting 314. 3 kWh/t; oxygen consumption 41.0 m^3/t; oxygen efficiency 87.7% ; metal yield 88.5% and tap-to-tap time 49. 5 min.
