Induction Forging Steel Rod End
Description
Induction Forging Steel Rod End With Induction Heating Machine
Objective To heat the ends of steel rods to 1800ยบF prior to a forgingย operation. Processing of the rods includes heating, pressing inย a two part die to forge the push rod end, and a final heating inย a channel coil to temper the rods and relieve the forgingย stresses. The customer needs to process rods of different
diameter between 1/8″ and 1/2″. The rod temperature must beย above 1400ยบF in the center while the outer edge can be asย high as 1900ยบF.
Material Steel rods of different diameters from 1/8″ to 1/2″
Temperature 1800ยบF
Frequency 50ย kHz
Equipment DW-HF-45kW output solid state induction power supplyย including a remote heat station containing 2 capacitors totalingย 0.5 ฮผF, along with a 6 turn (3 over 3) helical type coil.
Process The DW-HF-45kWย output solid state induction powerย supply was found to achieve the following results:
Results โข Both diameter steel rods reached 1800ยบF in less than 5ย seconds as measured by an optical pyrometer.
โข The 1/2″ rod was limited by the physical properties ofย steel with the time required to transfer the heat from theย outside edge of the bar to the center to raise theย temperature to 1400ยบF without melting the bar surface.ย The 1/8″ rod heating was limited by the inductionย heating efficiency at 80 kHz. Larger diameter barsย progressively heated faster up to the thermalย conductivity restrictions.
