1. Compared with heating by gas, fuel and coal, it is environmental friendly, easy operation, good working condition, heating instantly and consistently with good quality and without oxide layer. 
2. Compared with SCR based medium frequency furnace or electrothermal furnace. It can save 10%-50% energy. Its’ size is smaller by 1/3 and weight is lighter by 1/5. 
3. Equipped with cooling system and jacking system, easy to install and use.

 The principle of high frequency induction heating is that apply high frequency alernating current to a conduct that is curled to  cyclic (normally copper tube) to produce flux, then put the metal to this area to make the flux to run through it, and eddy current will be generated in the deriction of self-capturing with flux(rotary current), the induced current then generates heat under  the influence of the eddy current, so this heating method is called induction heating. hence, metal and other objects under heated can be heated without contact. at this moment, the character of the eddy current relies in that the induction heating on the object nearby the coil is outwardly strong but inwardly weak. with this principle. this heating body can be concentratedly heated where needed to achieve instantly effect, thereby the production output and work capacity are both improved.
