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.

Arc melting furnace main features

1: arc melting temperature up to 1980 ° C the melting furnace, the refractory metal most meltable.
2: melting time of 30-60 seconds,induction heating equipment minimizing volatile elements.
3: violent arc ignition, so that kind of completely melt mixing, excellent homogeneity.
4: Water-cooled copper crucible, the sample easily emerge without a release agent, and will not cause cross-contamination of samples and the crucible.
5: melting high purity argon environmental samples.
6: arc melting furnace,induction heating equipment small size, simple operation, without routine maintenance.

Melt furnace type

Melt furnace gas sub-type and two electric melting furnace.
Gas type advantages:Induction heating equipment suppliers observation sample molten state at any time, easy operation, low price. Cons: not as good as electric melting furnace precise temperature control required laboratory gas conversion.
Electric melting furnace advantages: high degree of automation, precise temperature control,induction melting furnaces a melting like a few more. Cons: Can not observed sample molten state.
