[0002] Medium frequency electric furnaces are used more and more widely in industry. The yoke of the medium frequency electric furnace utilizes electromagnetic induction to generate eddy current electric heating phenomenon to heat the surface of the workpiece for heat treatment. It has the characteristics of high production efficiency, low energy consumption, easy to realize automated production, less pollution and greater safety. The yoke is a yoke iron made of stacked steel sheets. It is evenly and symmetrically divided around the induction coil. After the steel sheets of the yoke are stacked, they are tightened with clamping plates, which can make full use of the magnetic conductive area of ​​the silicon steel sheet and reduce the heating of the medium frequency furnace body. The utility model is a yoke that does not require water cooling.

[0003] The existing magnetic yoke will cause more magnetic leakage when in use, and cannot fully utilize the magnetic conductive area of ​​the silicon steel sheet, thereby reducing thermal efficiency, and cannot perform temperature reduction treatment on the outer side of the magnetic yoke, thereby reducing the performance of the magnetic yoke.
