Smelting is a metallurgical process in which metal materials and other auxiliary materials are put into a heating furnace to melt, and the charge undergoes certain physical and chemical changes in the furnace. Such as: adjusting the content of alloying elements, adjusting carburization, deoxidation, degassing, and removing non-metallic inclusions. 

UnitedTest Medium Frequency Induction Furnace is the most advanced and most efficient and energy-saving smelting equipment, the use of electromagnetic field eddy current principle smelting, so that the electrical efficiency is greatly improved, is a sign of China's industrialization progress in recent years, in the progress of induction heating technology, making the refining simple and reliable.
