Blister packaging high frequency power supply application

Induction heating is widely used for surface quenching of gears, shafts, crankshafts, cams, rolls and other workpieces, in order to improve the wear resistance and fatigue resistance of these workpieces. The rear half shaft of the automobile adopts induction heating surface quenching, and the number of fatigue cycles under the design load is about 10 times higher than that of the quenching and tempering treatment. The workpiece material for induction heating surface quenching is generally medium carbon steel. In order to meet the special needs of some workpieces, low hardenability steels for induction heating surface quenching have been developed. Workpieces made of high carbon steel and cast iron can also be surface hardened by induction heating. The quenching medium is usually water or high molecular polymer aqueous solution.
