Furnace Transformer

Furnace transformer is used to melt the metals and ores in the electric furnace.
An electric arc furnace (EAF) 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 ironproducts) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and bydentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C (3,272 °F), while laboratory units can exceed 3,000 °C (5,432 °F). Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc, and the current in the furnace terminals passes through the charged material.
