Application Video: Induction Heating a Steel Rod for Forging

Jul 25, 2019 3:43:18 PM / by Brett Daly posted in forging, application video, induction forging, hot heading


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:

Forming a Steel Tube with Induction Heating

Jul 24, 2019 3:39:11 PM / by Brett Daly posted in Preheating, forging, forming


A client requested complimentary application testing from THE LAB at Ambrell for a preheating for forming application. They had been using a torch, but were interested in switching to induction heating due to the speed and repeatability that it offers. They needed to preheat an area around an elliptical hole in a large steel tube prior to forming. The target temperature for the application was 1800 °F (982 °C).

Induction Heating Magnetic Steel Parts (Cutting Tools) for Forging

Oct 23, 2018 4:44:56 PM / by Brett Daly posted in Applications Lab, forging

A client was introducing a new product line to the market and needed to heat magnetic steel parts, 
which would become cutting tools, for forging. The parts were knife blades and shears, and they needed a fast, repeatable heating process they could count on in production. Their objective was for each part to be heated in under seven seconds to 2150 ºF (1177 ºC).

A Complete Guide to Induction Forging

Jan 25, 2018 9:15:26 AM / by Brett Daly posted in forging, induction forging

Induction forging is a process in which an induction heating system preheats metals and presses them into shape using a hammer or press. The applications for induction forging vary greatly, but before you get started assessing your applications, it's helpful to have a good understanding of the process. So, let's get started.

Principal Process
First, it's important to understand that induction heating is a non-contact process that uses the main principles of electromagnetic induction in order to effectively produce heat. Electric current can flow through a material when it is placed in a strong alternative magnetic field; this causes Joule heating. With magnetic materials, the excess heat is generated below the Curie Point -- the Curie point is the temperature at which certain magnetic materials undergo a sharp change in their magnetic properties. The Curie point of iron, for example, is 1,418 degrees Fahrenheit (770 degrees Celsius).
