Forging a magnetic steel rodForging a magnetic steel rod

Testing determined that the magnetic steel rod heated to required temperature within 1.5 seconds with an EASYHEAT LI induction heating system.

Preheating steel rods for forging in a fastener manufacturing processPreheating steel rods for forging in a fastener manufacturing process

The client targeted an aggressive cycle time, achieve thanks to our process design and the efficiency of induction heating; fast heating means greater manufacturing throughput

Forging rods of various materials and dimensionsForging rods of various materials and dimensions

Each of the rods were placed into the coil and heated. They achieved the targeted temperature in 30-40 seconds. The coil was designed for a 5” (127 mm) heat zone.

Preheating a billet for forgingPreheating a billet for forging

The client needed to improve the cycle time of their gas furnace, and by preheating it prior to insertion into the furnace, time was saved and the client didn’t have to invest in doubling the size of their furnace.

Preheating a brass rod for forgingPreheating a brass rod for forging

The client wanted to cut the cycle time it was getting from a torch in half, and the Ambrell induction process was able to meet that goal.

Preheating a brass assembly for forging blanksPreheating a brass assembly for forging blanks

The client was using a competitor’s system, and it was heating the assembly at a slower rate. They needed to increase their production rate, which this solution was able to achieve.

Forging is a process where metal is formed into shape using pressure applied by an impact hammer or press. It is one of the oldest known metalworking processes. Metals can be forged cold, warm or hot. Cold forging is used for forming softer materials and smaller steel parts, but this process hardens the material making it brittle and difficult to process after forging. Hot forging is when a part is heated above the material recrystallization temperature before forging, typically 1100°C (2012°F). Warm forging is forging a part below the recrystallization temperature, typically below 700°C (1292°F). Read more in our 8 page brochure!

Induction heating is an optimal option for many forging applications. The process and economic inefficiencies of gas furnaces or flames are avoided with this unique technology which quickly and accurately delivers the required heating to the workpiece only. Additional benefits accrue since the heating can be integrated into the forging process nearest to the die. With Ambrell's modern technology, remote workheads are placed directly into production lines for high volume rapid forging processes.
Hot forging takes place at workpiece temperatures above which recrystallization occurs. This process requires uniform through-heating. Typical part geometries are simple, often comprising of bar stock, tubular products and sheet metal.
