世界钢铁工业的发展越来越强烈地受能源杠杆的制约。我们以此为出发点,希望能得到一种适合我国国情的新型炼钢模式。通过现有炼钢方法各种组合模式的能耗对比发现,废钢竖炉—转炉法和废钢竖炉—电炉法的综合能耗最少。因为铁水热装不但给电炉带来了可观的物理显热,更重要的是使电炉及早形成熔池,使电炉吹氧助熔提前40—50
The development of the world steel industry is increasingly constrained by energy levers. Taking this as our starting point, we hope we can get a new type of steelmaking model that suits our national conditions. By comparing the energy consumption of the various combinations of the existing steelmaking methods, it is found that the combined energy consumption of the shaftless shaft-converter method and the shaft-shaft furnace-scrap method is the lowest. Because hot metal hot water not only brought substantial physical sensible heat to the electric furnace, more importantly, the electric furnace forms the molten pool as early as possible, so that the electric furnace blows the oxygen to melt in advance 40-50
