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.
