Induction Heating Steel Part For Hot Heading

Induction Heating Steel Part For Hot Heading With IGBT Induction Heater

Objective Heating steel parts to 1900ºF (1038ºC) for hot heading application
Material Steel parts with 7/16” (11.11mm) OD and ceramic piece
Temperature 1900 ºF (1038ºC)
Frequency 440 kHz
Equipment • DW-UHF-6kW induction heating system, equipped with a remote workhead containing one 0.66μF capacitor.
• An induction heating coil, designed and developed specifically for this application.
Process A four turn helical coil with ceramic insert is used to heat a 0.75” (19mm) section of the part to 1900ºF (1038ºC) for 7.5 seconds. A ceramic piece is so the part does not come in
contact with the coil.
Results/Benefits Induction heating provides:
• Hands-free heating that involves no operator skill for manufacturing
• Direct application of the heat on the work piece with precision and consistency
• Even distribution of heating
• Low pressure and minimal residual part stress

Induction Heating Steel Pipe To Remove plastic coating

Induction Heating Steel Pipe To Remove plastic coating With RF Heating System

Objective Recover the polypropylene insulation from hollow steel tubes to allow recycling of both the tubes and the insulation.
Material Hollow steel tubes 1/8” (0.318 cm) to 5/8” (1.59 cm) ID
Protective polypropylene coating
Temperature 150 ºC (302°F)
Frequency 185 kHz
Equipment • DW-UHF-4.5kW induction heating system, equipped with a remote workhead containing one 1.5 μF capacitor
• An induction heating coil designed and developed specifically for this application.
Process/Narrative A six turn letterbox shaped coil is used to heat the inner steel pipes. The plastic coating is softened enough to be easily removed and recycled. The time required to melt the plastic from one meter of wire is approximately 45 seconds. This varies based on the diameter of the tube.
Results/Benefits Induction heating is the only feasible way to remove the plastic coating,
leaving it in an unpolluted form for recycling. It is a faster processing method and also reduces in the company’s carbon footprint.

induction heating steel casting

Objective To preheat two irregularly shaped steel castings to be molded and bonded with synthetic rubber
Material Two steel castings, 17 lb. irregularly shaped, approximately 6” (152mm) x 9” (229mm) x 1” (25.4mm)
Temperature 400 ºF (204 ºC)
Frequency 20 kHz
Equipment • DW-MF-45kW induction heating system, equipped with a remote workhead containing four 1.0 μF capacitors (for a total of 1.0 μF).
• An induction heating coil designed and developed specifically for this application.
Process Two steel castings are placed onto an insulated plate with brass guide location pins. The plate is placed onto a table which slides into a large multi-turn helical coil. The parts are induction heated to 400 ºF in 180 seconds. The slow heating time allows the parts to come up to temperature evenly. When the heating cycle is completed each part is placed into a press for the molding and bonding operation.
Results/Benefits Induction heating for bulk preheating of steel castings
produces:
• efficient and repeatable heat vs. a torch or an oven.
• even heating of parts throughout
Large multi-turn coils provide:
• easy loading and unloading of the parts
• flexibility for varying bulk castings sizes and geometries
