Main Features of Induction Melting Furnace:


1, Fast Melting speed ,  melting temperature is uniform, the oxidation loss is less, and the metal composition is uniform.

2, Strong adaptability , flexible usage in melting. In the medium frequency induction furnace, the molten steel can be completely pour out of the furnace, change the melting material is  convenient.

3,Adopt Excellent coil design and high quality thick wall copper tube,  the  reasonable optimization of design parameters which make the induction coil conversion efficiency the highest, the minimum resistance, more energy can be used in  smelting, and our induction coil is not easy to cause damage due to the arc and expansion force.

4, The solid coil support system makes every coil tightly locked, eliminating inter turn short circuit, and overcoming the driving force of electromagnetic force, which can greatly prolonging the service life of lining.

5, The lining leakage alarm system is installed in the bigger capacity furnace, not only to detect the leakage of the furnace, but also can  connect the high pressure to the ground to ensure the safety of the operation.
