Strip heating purpose:
1. Annealing of high-strength steel
2. Preheating or hot forming before forging
3. Drying, degrease and preheating before spraying
4. Soft melting after galvanizing
5. Stainless steel solid solution, etc.
Equipment selection
1. High frequency and medium frequency and super-audio power supply will all used if adopts induction heating.and the selection need consider the material,width,thickness,temperature,speed etc.comprehensive factors of the heated strip steel.
2. Contact type pass through resistance heating can be used DC power supply or low-frequency power supply,which is generally low-voltage and high current.
