摘要
在分析附加电抗电弧炉电气特性的基础上,综合考虑影响生产成本的各要素,建立以缩短冶炼时间、降低吨钢电耗、减少电极消耗、增加炉衬寿命为目标的多目标供电优化模型.该模型充分考虑了电流对电极和炉衬的影响,以及附加电抗、供电电压对供电策略的影响,实现了对附加电抗、供电曲线以及工作电流3个参数的优化选取.将优化的供电曲线用于指导实际工业生产,结果表明,不但生产效率得以提高,而且综合经济效益也有所提高.
Analyzing the electric characteristics of a supplemental reactor electric arc furnace（SR- EAF） and comprehensively considering the influencing factors on production cost, we developed an optimized power supply model, where the multiple objects aiming at shortening smelting time, reducing electric power consumption per ton of steel, decreasing electrode consumption and prolonging lining life were employed in optimization. The effects of current on electrodes and linings and effects of a supplemental reactor and the output voltage of a transformer on power supply strategy were taken into account in this model, with such parameters optimized as the current of electric arc, the values of a supplemental reactor and service voltage. A new power supply strategy based on the optimized parameters was proposed and applied in actual production, which increased power supply efficiencies and economic benefits.
