Note: Heating a steel tie down (loosen steel pin)
Objective:
Heat steel tie downs on containers to loosen steel pin so pin can rotate
End Product:
Steel tie-down assembly
Equipment:
Ambrell 10 kW induction heating system, equipped with a remote workhead containing two 1.5 μF capacitors for a total of 0.75 μF
An induction heating coil designed and developed specifically for this application
Materials:
Steel tie-down assembly with a 2.5 in (63.5 mm) dia. flange
1 in (25.4 mm) dia. rod and pin ring approx 4 in (101.6 mm) OD
0.75 in (19.05 mm) thick steel
Temperature:
1000 °F (538 °C)
Frequency:
282 kHz
Testing:
A single-turn helical coil is used to heat the assembly. The coil is placed around the pin and power is applied for 120 seconds. After heating, a steel rod is inserted in the pin ring, pressure is applied and the pin ring spins freely.
Benefits:
-
Precise and accurate placement of heat without affecting surrounding areas
-
Much faster process time, from hours to minutes
-
Repeatable and consistent results
-
Even distribution of heating
