Product Description
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.
