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:
