The electric furnace transformer is the power transformer of the steelmaking electric arc furnace. The capacity of the electric furnace transformer is configured according to the size of the electric arc furnace and the smelting process. It meets the requirements of smelting process by means of voltage regulation. There are two voltage regulation modes: on load voltage regulation and non excitation voltage regulation. Large furnace transformers with on load voltage regulation do not have a series reactor, and small and medium-sized furnace transformers with non excitation voltage regulation can be divided into two types: those with a series reactor and those without a reactor. These two types of structures can change the impedance under the highest two voltages.
The former changes the impedance by switching on and off the series reactor. The latter changes the winding impedance by changing the connection mode of the high-voltage winding of the furnace transformer itself.
The iron core of the electric furnace transformer is made of high-quality oriented silicon steel sheet, fully automatic cutting line processing, 45 degree full inclined joint, non punching, and weft free glass tape binding process. The coil adopts the latest international main longitudinal insulation structure. The winding structure and insulation shall be reasonably selected to ensure that the winding has sufficient mechanical strength. It has the characteristics of strong short-circuit resistance, strong overload capacity, high efficiency, low loss, safety and reliability.
In the metallurgical industry, electric furnaces are used to smelt high-quality alloy steel, ferroalloy, etc;
In the chemical industry, electric furnaces are used to produce yellow phosphorus, calcium carbide, synthetic resin, etc;
In the machinery industry, electric furnaces are used for smelting cast steel and cast iron.
