Magnetic cores of induction furnaces are made of transformer steel and serve to localize the magnetic field around the inductor, thereby increasing the efficiency of the inductor and reducing heating in the structural elements of the furnace. The shunt metal structures can be made of both conventional structural steel and non-magnetic steel, according to the customer’s specifications, our company also has experience in manufacturing magnetic cores with cooling by copper tubes. If a replacement of the magnetic circuit is required in the absence of documentation (TOR), our experienced engineers can go to the facility and draw up a TOR based on measurements of spent magnetic circuits.
