Preheating steel rods for forging in a fastener manufacturing process

From Ambrell

Induction is effective heating steel rods to 2100 ºF (1149 ºC) evenly across their length in 25 seconds. This innovative solution employs eight coils to heat eight rods to the desired temperature in a parallel process...
