在建立不同铁水比例下的能量平衡与物料平衡的基础上,利用多尺度方法分析研究衡阳华菱钢管有限公司电弧炉炼钢跨尺度全流程能量的状况,主要包括工位级节能技术研究、余热利用技术、工位级间相互的关系与电弧炉炼钢流程集成技术。实现了跨尺度全流程能量的集成,得出最优能耗的冶炼生产模式。 Based on the energy balance and material balance under the different ratio of hot metal to molten steel, the multi-scale method was used to analyze the energy of cross-scale whole process of electric arc furnace steelmaking in Hengyang Valin Steel Pipe Co., Ltd., mainly including research on station-level energy saving technology, Use of technology, the relationship between workstation level and EAF steelmaking process integration technology. It realizes the integration of energy across the whole scale and obtains the smelting production mode with the best energy consumption.
