In the latest induction heating application video from THE LAB at Ambrell, a steel rod is heated for a forging application with an Ambrell EASYHEATTM induction heating system and a custom-designed coil. As you'll see in the video, heating the steel bar to 2220 °F (1204 °C) took just 20 seconds. Here is the preheating for forging video:
A fastener manufacturer contacted THE LAB at Ambrell as they needed to preheat steel wire prior to hot heading. The end products were screws. They wanted to heat steel wire to 350 °F (177 °C) within seconds. They turned to induction because they wanted to increase tool life with hot heading, as cold heading is harder on tooling.
