induction heating stainless steel wire cable
Objective
Induction Heat stainless steel cable made from stranded wire with induction for stress relief. Heating is performed while the cable is static to determine the required power needed to meet the customer’s listed production rate of 1,000 ft/hour (305 m/hr).
Test 1
Key Parameters
Power: 4.03 kW
Temperature:
(a) 950°F (510°C)
(b) 1200°F (648°C)
(c) 1500°F (815°C)
Time:
Static heating 5.5″ (14 cm) of cable:
(a) 3 seconds
(b) 4 seconds
(c) 7 seconds
Test 2
Key Parameters
Power: 4.03 kW
Temperature:
(d) 950°F (510°C)
(e) 1200°F (648°C)
(f) 1500°F (815°C)
Time:
Static heating 5.5″ (14cm) of cable:
(d) 2 seconds
(e) 4.2 seconds
(f) 8.8 seconds
Process:
Static heat tests: the wire was maintained at a fixed position, under tension, in the coil for all tests. Induction heat was applied until the desired temperature was achieved.
Results/Benefits:
- Cable #2024 can be heated to the specified temperature of 900-950°F at the rate of 1000ft/hr (305 m/hr). Cable #2019 can be heated with the same power supply and coil arrangement at a lower line speed estimated to be 825 ft/hr (251m/hr).
- A system with a higher kW power output can meet the needs of 1000ft/hr (305 m/hr) rates at the higher temperature requirements.


induction heating steel cable for cutting with radio frequency heating equipment
Objective Prior to cutting, heat a short section of a hardened steel cable coated with a polyethylene sheathing.
Material Multi-strand braided stainless steel cable 0.5 in. (1.27 cm) OD enclosed within a polyethylene sheathing
Temperature 1800 ºF (982) ºC
Frequency 240 kHz
Equipment • DW-UHF-20kW induction heating system, equipped with a remote workhead containing four (4) 1.0 μF capacitors (for a total of 1.0 μF).
• An induction heating coil designed and developed specifically for this application.
Process A three-turn helical coil is used to heat the cable in approximately 2 seconds. After the power is turned off, the heat is then transferred to the sheathing.
Results/Benefits Induction heating provides a quick, precise repeatable method to reach the high temperature required. It is a very efficient heating method.
