Briefly describe the scope of use of electric furnace transformers

The electric furnace transformer is the power transformer of the steel-making electric arc furnace, and the capacity is equipped according to the tempering process. It meets the requirements of the tempering process by means of voltage regulation.

Voltage regulation methods are divided into two types: on-load voltage regulation and non-excitation voltage regulation. Large-scale equipment with on-load voltage regulation does not have series reactors. There are two types without reactors. These two structures can change the impedance under high secondary voltage. The former depends on the input and removal of the series reactor to change the impedance, and the latter depends on the combination of the high-voltage windings of the furnace transformer itself. Winding impedance.

The iron core of the equipment is made of oriented silicon steel sheet, automatic cutting line, 45 degree full oblique seam, no punching, no weft glass adhesive tape binding process. Reasonable selection of the structure of the winding ensures that the winding has appropriate mechanical strength. Strong ability to withstand short circuit, good overload performance, high efficiency, low loss, reliability and other characteristics.

In the metallurgical industry, electric furnace transformers are used to smelt alloy steel, ferroalloys, etc.; in the chemical industry, for the consumption of synthetic resins, etc.; in the machinery industry, for the smelting of cast steel and cast iron, etc.
