Note: Annealing the end of steel wire on a woven wire mesh

Objective:

To heat 3” (76.2mm) from the end of the wire on a woven wire cloth 60” (1.52m) long. This prepares the wire mesh for bending in a press brake. 

End Product:

woven wire cloth

Equipment:

  • Ambrell 250 kW induction heating system, equipped with a remote workhead containing three 25µF capacitors for a total of 75µF
  • An induction heating coil designed and developed specifically for this application. 

Materials:

Woven wire cloth (steel) made of 1/2” (12.7) diameter wire, 60” (1.52m) long. Wires are 1.5” (38.1) apart 

Temperature:

1400 ºF (760 ºC)

Frequency:

9.1 kHz

Testing:

A two turn oval coil is used to heat the woven wire. The woven wire is placed in the coil and heated for 15 seconds to soften a 60” (1.52m) length of the wire 3” (76.2mm) deep. The woven wire is then placed in a press brake for the bending process. 

Benefits:

Induction heating provides:

  • Faster production process

  • High efficiency, low energy costs compared to gas furnace

  • Fast, controllable process

  • Hands-free heating
