High Frequency Heating Steel Pipe With Induction Heating Equipment
Objective To heat a steel pipe to 1100ยบF (593ยบC) to transport meltedย magnesium
Material Steel pipe 14.5โ (4.42m) long with a 3.5โ (88.9mm)OD
Temperature 1100ยบF (593ยบC)
Frequency 9 kHz
Equipment โข DW-MF-160kW induction heating system, equipped with aย remote workhead containing one 25ฮผF capacitor.
โข An induction heating coil designed and developedย specifically for this application.
Process A specially designed double U channel coil the length of theย pipe is used in this application. The pipe is placed inside theย coil and power is supplied. The voltage is set and the powerย output is 100kW. As the part reaches the Currie point theย power drops to 80kW and the voltage must be increased toย achieve the 140kW. The pipe reaches 1100ยบF (593ยบC) in 20ย minutes.
Results/Benefits Induction heating provides:
โข Controllable and repeatable heat pattern that keeps
material in liquid form
โข Environmentally friendly
โข Even distribution of heating
โข Movable workhead that can be located away from theย power supply
