Heating an area around elliptical hole in steel tube prior to forming; the client had been using a torch for this application.
Hot Heading Steel Wire: Create Screws
Preheating steel wire before hot heading to create a screw; they wanted to switch from cold heading to extend tool life.
Heating Cutting Tools for Forging
An infrared pyrometer was used to monitor the temperature of the part during the heating cycle. Two parts were tested.
Flattening/Bending Steel Tubes
Induction forging elevates the temperature much more rapidly than an oven, targeting the precise portion of the part that requires heating every time, presenting a significant advantage over an oven
Induction heating drove the part to forming temperature more rapidly than a torch. Induction heating targets the precise portion of the part that requires heating every time
Testing determined that the magnetic steel rod heated to required temperature within 1.5 seconds with an EASYHEAT LI induction heating system.
Induction forging silver bars to create collectible coins
The client had been using an oven, and forging with induction can present some speed advantages. Unlike an oven, induction heating offers instant on/instant off heating
Preheating 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
Induction forging rods of various materials and dimensions
Each of the rods were placed into the induction forging 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 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 billet with induction 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 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.
Preheating steel rods for forging in a fastener manufacturing process
The client targeted an aggressive cycle time, which Ambrell was able to achieve thanks to its process design and the efficiency of induction heating
Preheating for forging of steel pins
Fast, precise heating of the pin - 2 minutes and 36 seconds were saved on heating all of the rim's pins when compared to using a torch
Preheating titanium rods for forging turbine blades
Forging with induction provides increased production rates, repeatable, reliable & consistent heat without flame and hands free heating that involves no operator skill for manufacturing
Pre Heating Mold Release Push Rod For Forging
To heat the ends of steel rods to 1800°F using induction prior to a forging operation. Processing of the rods includes heating, pressing in a two part die to forge the push rod end, and a final induction heating in a channel coil to temper the rods and relieve the forging stresses.
Heating Inconel Billets for Forging
A four-turn helical coil is used to deliver uniform heat to the inconel billets. Both size billets heat to 2050°F (1121.1ºC) within 12 seconds.
Pre Heating Steel For Forging Horse Shoes
Induction forging provides for hands-free heating that involves no operator skill for manufacturing, improved production rates with minimal defects, low pressure and minimal residual part stress with even distribution of heating
-
Can induction be used for forging?
Yes, a superior alternative to furnace heating, induction heating provides faster, more efficient heat in forging applications.
-
Can induction forge any size part?
In addition to the amount of energy required to heat the part to the forging temperature, the size of the part will also dictate the required operating frequency of the induction system to optimize operating efficiency.
-
What are some benefits of induction forging?
The process relies on electrical currents to produce heat within the part that remains confined to precisely targeted areas. High power density means extremely rapid heating, with exacting control over the heated area. Recent advances in solid-state technology have made induction heating a remarkably simple and cost-effective heating method.
-
What is through-heating?
The induction forging process produces heat within the part, but the heat is generated near the outside surface and will take time to conduct to the center of the part. Typically, bar-ends up to 20 mm in diameter through-heat in less than 10 seconds, whereas a 75 mm diameter bar will take 150 seconds to heat to the center.
-
What is hot forging?
Hot forging is when a part is heated above the material recrystallization temperature before forging, typically 1100 °C (2012°F). Hot forging allows a part to be formed with less pressure, creating finished parts with reduced residual stress that are easier to machine or heat treat.
