Objective
Induction preheating of steel tubes with diameters of 14 mm, 16 mm, and 42 mm (0.55”, 0.63”, and 1.65”). A 50 mm (2″) length of the tube much be heated to 900°C (1650°F) in under 30 seconds.
Equipment
- UPT W15/ 150 Power Supply
- HS-8 Heat Station
Materials
- Steel tubes with ODs: 14 mm, 16 mm and 42 mm (0.55”, 0.63”, and 1.65”)
- Wall thicknesses: 1mm, 2mm, and 2mm (0.04″, 0.08″, 0.08″)
Key Parameters
- Power: 5 kW for 42mm tube, 3 kW for 14 and 16 mm tubes
- Temperature: 1740°F (950°C)
- Time: 26 sec.
Process:
- Insert steel tube into the coil.
- Apply induction heat for 26 seconds.
- Remove the tube from the coil.
Results/Benefits:
The desired preheating temperature was achieved for less than 30 seconds for the three different steel tubes. Our 5 kW induction system can be used for successfully preheating of steel tubes with different diameters and thicknesses.
