It works based on the principle of the high frequency big current generating the strong magnetic field in the loop, and them the strong magnetic field generating the bow wave to rise the oven temperature rapidly to make the coating material on the welding seam melted and solidified equably.
**The production speed and applicable can diameter is customization.
Induction drying coil: Adopts rare-earth material as the magnetizer of induction coil to guarantee stability and good drying effect in long-time heatin, to achieve the goal of high efficiency and energy saving.
Power Suppy Control Technology: The high-frequency induction inverter power static sine wave generator adopts bilateral SPWM pulse modulated wave, which can effectively control the output signal of the AC current to avoid the zero point of the oscillation and protect the control circuit from being effected by unstable of general power supply and its own easily-damaged nature.
Innovation: 1. no need of high-frequency transformer and copper pipe induction coil, reducing the instablity of machines and copper pipe deformation caused by the chilling water, which results in bad effect of coating drying.
2. heating on the welding seam area from inside to outside to make a thorough curing for the coating material.
