The Advantages of Induction Heating Steel Sheets Production

Induction heating steel sheet is a process that involves using an electromagnetic field to heat up a metal object. In this case, the object is a steel sheet. The steel sheet is placed within the electromagnetic field, and the energy from the field causes the steel to heat up. This method of heating is fast … Read more

Induction Heating Steel Part For Hot Heading

Induction Heating Steel Part For Hot Heading With IGBT Induction Heater

Objective Heating steel parts to 1900ยบF (1038ยบC) for hot headingย application
Material Steel parts with 7/16โ€ (11.11mm) OD and ceramic piece
Temperature 1900 ยบF (1038ยบC)
Frequency 440 kHz
Equipment โ€ข DW-UHF-6kW induction heating system, equipped with aย remote workhead containing one 0.66ฮผF capacitor.
โ€ข An induction heating coil, designed and developedย specifically for this application.
Process A four turn helical coil with ceramic insert is used to heat aย 0.75โ€ (19mm) section of the part to 1900ยบF (1038ยบC) for 7.5ย seconds. A ceramic piece is so the part does not come in
contact with the coil.
Results/Benefits Induction heating provides:
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Direct application of the heat on the work piece withย precision and consistency
โ€ข Even distribution of heating
โ€ข 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 allowย recycling of both the tubes and the insulation.
Material Hollow steel tubes 1/8โ€ (0.318 cm) to 5/8โ€ (1.59 cm) ID
Protective polypropylene coating
Temperature 150 ยบC (302ยฐF)
Frequency 185 kHz
Equipment โ€ข DW-UHF-4.5kW induction heating system, equipped with a remoteย workhead containing one 1.5 ฮผF capacitor
โ€ข An induction heating coil designed and developed specifically forย this application.
Process/Narrative A six turn letterbox shaped coil is used to heat the inner steel pipes. Theย plastic coating is softened enough to be easily removed and recycled. Theย time required to melt the plastic from one meter of wire is approximately 45ย 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 processingย method and also reduces in the companyโ€™s carbon footprint.

induction heating steel casting

induction heating steel casting ofย rubber mold with high frequency induction heater

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