Induction heater Parameter Design

According to the different parameters of the wind turbine bolt,our engineer will optimizatized design different inductor group to get the effect of high efficiency. The inductor for tempering will increase the inductor quantity and adding tempering holding box to get better structure after tempering, ensuring the wind turbine bolt performance meets the requirements.
