Product Description

It is used in processes such as ore-arcing furnaces and electroslag furnaces, and can be used to melt and cast more than 400 types of steel, including carbon steel, alloy structural steel, bearing steel, and mold steel. The main circuit uses a three-phase fully controlled bridge and double reverse star as the basic unit topology. It can form a 12-pulse, 24-pulse, and other multi-pulse combination structures through transformer phase shifting to meet the needs of different working conditions, effectively reduce harmonic pollution, and improve reliability.
