120MVA Electric Arc Furnace Transformer
The transformer specializes in power supply for various industrial electric furnaces.
Successful installation, testing, commissioning and start up the 125mva 35kv EAF transformer on 2008.
Our company mainly produce the following furnace transformer:
High impedance furnace transformer, DC arc furnace transformer, ladle refining furnace transformer, submerged arc furnace transformer (including ferroalloy furnace tran- sformer, calcium carbide furnace transformer, yellow pho- sphorus furnace transformer,single phase titanim slag furnace transformer etc.), electro slag furnace transformer, frequency induction furnace transformer, single-phase graphite furnace transformer, and includes resistance furnace transformer, EAF transformer and induction furnace transformer.etc.
Main function and characteristic
Electric furnace transformers are transformers which supply power to the electric furnaces. It can drop high voltage to the working voltage the electric furnaces need.
There are many kinds of electric furnaces,so there are many kinds of electric furnace transformers cooperating with them.Now,our company manufactures following electric furnace transformers:electric furnace transformers used in steelelectric furnaces(including on-laod,no-load and enclosed reactor) ; mineral hot furnace transformers used to smelt kinds of iron alloys,hydrosilicons,carbides,etc(single phase,three phases on-load and no-load tap changer).They are low loss and energy-saving products.Cooling methods are self-cooling, forced oil water cooling, etc.It can be designed specially according with customers' requirements.
The model of the electric furnace transformer is expressed as follows:
The meaning of model:
H--Steelmaking arc furnace,HJ--ladle furnace,HZ--electro-slag furnace,HC--calcium carbide furnace,HK--mineral hot furnace,HG--line frequency induction furnace;
