Induction Forging Turbine Blades

Sep 4, 2020 12:37:44 PM / by Brett Daly posted in Applications Lab, forging



A company in the turbine industry needed to heat titanium rod blanks prior to forging them into turbine blades. Heating needed to occur in a very precise fashion. The blanks had to heat to 2,030 ºF (1,110 ºC) with a tolerance of plus or minus 25 ºF (-3.9 ºC) with uniform heat from the surface to the core. THE LAB at Ambrell determined that an EKOHEAT 20 kW, 50-150 kHz induction heating power supply with a workhead and nineteen-turn helical coil specifically designed for this application would meet this application's requirements.

Preheating a Billet for Forging

May 29, 2020 4:27:46 PM / by Brett Daly posted in Applications Lab, forging



A customer needed to preheat a billet to 250 ºF (121 ºC) for forging. After forging, it was going to be rolled into bars. The tested material was a 5.5 inch (140 mm) wide billet that was 62 inches (1575 mm) long. The LAB at Ambrell determined that an Ambrell EKOHEAT 250 kW, 5-15 kHz induction heating power supply with a workhead and pancake coil specifically designed for this application would meet the customer's requirements.

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).
