what is Electric Arc Furnace?
Electric Arc Furnace is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Electric arc furnace temperatures can be up to 1,800 degrees Celsius. Arc furnaces differ from induction furnaces in that the charge material is directly exposed to the electric arc, and the current in the furnace terminals passes through the charged material. Electric Arc Furnace can get better steel than induction furnace. The steel from electric arc furnace has less of sulfur and phosphorus. Then it’s mechacnical property will be good.
