Product Description

product introduction:
The ladle transformer is used as a ladle power transformer. Using a high-power electric furnace, the furnace and
Continuous casting and rolling refining external "four-element" process equipment, is the direction of development.
Chinese iron and steel enterprises. The process of molten steel begins to refine, respectively, in two different
Equipment. The furnace and the initial adjustment only play the role of the furnace, the composition of high-power function.
Fully improve the production capacity of the electric arc furnace and increase the output of steel. however after
The quality of the second refined steel is highly improved and easy to adjust, which greatly improves the steel
components, expanding the variety of ladle, so it has been widely used. Introduced since the early 1970 s
China's ladle, the production of similar products also emerged, in the 1990 s ladle and ladle transformer are open
Fast, and 1997 industry standard JB/Implementation T8594-1997 "ladle.

Main Functions and Features
The electric furnace transformer is a transformer that supplies power to the electric furnace. It can go down very high
Voltage to the working voltage required by the electric furnace.
There are many kinds of electric furnaces, so there are many kinds of electric furnace transformer
Now, our company produces the following electric furnace transformer: electric furnace transformer
For iron and steel electric furnaces (including on-laod, no-load and closed reactors); mineral hot furnaces
Used for smelting various ferroalloys, water silicon, carbide, etc. (single-phase, three-phase load) transformer
and no-load tap changer). They are low-loss and energy-saving products. The cooling method is self-cooling,
Forced oil and water cooling, etc. It can be specially designed according to customer's requirements.
