对平炉冶炼有很大意义的是从火焰到钢水的热传递,这种热传递在很大程度上决定整个冶炼过程的热力学和动力学,同时也与火焰的气体动力学性能及火焰与炉料的位置有很大关系。炉膛的火焰位置可用阿基米德准数Ar=(gr_0/W_0~2)×(△T/T_(cp))近似地求
Of great significance to the hearth smelting is the heat transfer from the flame to the molten steel. This heat transfer largely determines the thermodynamics and kinetics of the smelting process. At the same time, it also relates to the gas aerodynamic performance of the flame, Location has a lot to do with it. The flame position of the furnace can be approximated by the Archimedes quasi-Ar = (gr_0 / W_0 ~ 2) × (ΔT / T_ (cp))
