steel melting furnace has what?

steel melting furnace has what? BOF, open hearth, EAF, the other has a vacuum induction furnace, vacuum arc,aluminium melting furnace electron bombardment furnace steel melting furnace using low-ash coal and natural gas, oxygen gas flame heating, and a high speed oxy-fuel burner lance high purity oxygen gas is blown into the melt. steel melting furnace main feature is the pool stirring ability; heat treatment equipment intermittent rotation by appropriate arrangement of the burner and furnace, the reaction can also be expanded; good secondary combustion system of multi-level effects; blowing rate. UHP steel melting furnace in the energy input per unit of time is much higher than ordinary power electric arc furnace, which is equivalent to an ordinary power electrode sections are not competent.High Frequency Induction Increase the electrode section will make it support, drive and even bulky structure of the entire furnace, but also cause difficulties for the control system.
