Hot working is defined as deformation that takes place at a temperature 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.
Modern induction heating provides many advantages over other heating methods. Heating with induction provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time.
Solid state RF induction heating is a prime candidate for many forging applications. Historically, gas furnaces or flames were used to heat metal for hot working. These methods are inefficient in terms of both energy and time. However, induction heating can provide the necessary heat for forging in a very efficient, accurate, reliable, and repeatable manner. With Ameritherm's modern technology, remote heat stations can be placed into production lines for high volume rapid forging processes.
Induction heating systems tycally used for forging range from 3 to 40 kW, depending on material and application requirements.
