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.

Electric arc steel melting furnace use

High power steel melting furnace (HP) and UHP (UHP) is relative to an ordinary power electric arc furnace (RP) in terms.heat treatment machine They mainly by how much per ton furnace capacity distribution transformer capacity to distinguish. 20 tons above the stove, oven ordinary power electric arc furnace tonne capacity of about 300 kVA transformer capacity, high-power electric arc furnace to about 450 kVA, while UHP compared to 600 kVA or more, and have more the trend to higher. Enter the electric arc furnace heat per unit of time within which means a substantial increase significantly shorten the time to make melt, thereby increasing production capacity, reduce electrode consumption, reduce heat loss and reduce energy consumption, the result is to make the production costs. For example in Japan of a 70 t UHP, 60000 KVA transformer capacity, refining steel balls,aluminium melting furnace coupled with refining, smelting cycle is only 70 minutes, the equivalent of producing one ton of steel per minute high. To make the best electric furnace system can (to the fullest and most economical use of electricity) work under a lot of high power steel melting furnace using computer control. UHP's power, the unit of time the furnace heat input is also large, refractories has become a weak link. Research and the use of steel coated with a water-cooled furnace wall refractory and the lid.
