Electric furnace transformers are categorized into various types such as electric arc furnaces, mineral electric furnaces, refining furnaces, electroslag furnaces, and salt-soluble furnaces. They are primarily used for smelting products including silicon carbide, ferrosilicon, calcium carbide, sulfur, graphitization, welding flux, cast steel, ceramic sand, pearlite sand, metallurgical auxiliary materials, ferromanganese carbide, ferromanganese aluminum, vanadium iron, vanadium aluminum, and silicomanganese alloy. We supply units with voltage ratings up to 110kV, capacities up to 32,000kVA, and individual weights up to 120 tons.
Throughout history and across cultures, there has been insufficient recognition of the energy-saving potential of electric furnace transformers, leading to certain misconceptions. A single furnace transformer consumes electricity ranging from tens of thousands to hundreds of thousands of kilowatt-hours daily, resulting in staggering energy waste. Addressing this issue, our company has developed multiple energy-efficient electric furnace transformer models over the past decade. Notably, in 2013, we introduced high-power-factor energy-saving electric furnace transformers with an average power factor of 0.93 (compared to approximately 0.8 for conventional products). A single 12,500 KVA furnace transformer can save over 20,000 kWh daily while eliminating the need for reactive power compensation equipment investment.
