Hsspt -30000/33kv Ladle Furnace Transformer 30mva for Steel Plant Furnace

Product introduction:

Ladle transformer is used as ladle power transformer. Using high power electric furnace, the furnace and

continuous casting and rolling refining outside “quaternary” process equipment, it is the development direction

of Chinas steel enterprises. The process of molten steel is beginning to refine and respectively in two different

equipment. To melt and initial adjustment only plays the role of furnace, composition of high power function

adequately, increase production capacity of electric arc furnace, improve steel production. However after

second time refine the quality of steel was improved highly and easy to adjust, which greatly improve steel

components, expand the varieties of steel ladle, so is being widely used. In the early 1970s introduced from

China, ladle, production of similar products also arise, in the 1990s ladle and ladle transformer have developed

rapidly, and in 1997 by the industry standard JB/implementation of T8594-1997 “ladle.

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;

Number of phase:D–single phase,S–three phase;

Types of cooling device :ONAN,wind cooling F,water cooling S.

The methods of oil circulation:natural circulation,forced oilcirculation P.

Tap changer:off-circuit tap changer,OLTC Z.

Enclosed attached device:changing leakage flux,enclosed reactor K.
