Note: Preheat Steel Plates Prior to Bending
LSR# 36385
Objective:
To heat steel tower parts prior to bending
End Product:
steel tower parts
Equipment:
Ambrell EKOHEAT 250 kW, 5-15 kHz induction heating system, equipped with a remote heat station containing (16) 10μF capacitors for a total of 40 μF.
Materials:
Various steel plates from 0.25 - 1.25 in (6 - 32 mm) thick
Temperature:
1740 °F (950 °C)
Frequency:
13 kHz
Testing:
A specially-designed helical coil was used to provide the heat to the multiple samples provided. Initial tests were conducted to optimize the power delivered to the part and to understand the heating patterns achieved. After several changes and iterations on the coil setup the following data is collected from the testing.
Benefits:
-
Uniform and repeatable performance
-
Faster application time
-
Non-contact heating
