There are many parameters to be considered in designing an induction billet/bar heating system to meet the needs of modern forge shops. Application experience and computer modeling capability are important tools in developing effective induction heating system and avoiding unpleasant surprises related to common incorrect assumptions. Some of those incorrect assumptions that affect the quality of heated billets and bars are discussed in this article.

Numerical computer modeling is one of the major factors in successful design of induction heating systems. In the fast-pace global economy, the ability of induction heating manufacturers to minimize the development time and shorten the "learning curve" through efficient computer modeling is critical for a company's success. In an attempt to further excel piston's manufacturing technology, Federal-Mogul specialists have combined their efforts with experts from Spinduction Weld Inc. which recently developed a novel welding process - Spinduction™ and with Inductoheat, Inc. - indisputable leader in designing and computer modeling of novel induction heating systems.

Today's forge shop must quickly adjust to a rapidly changing business environment while satisfying continuously increasing demand for greater quality of forged parts and environmental friendliness of process equipment. Steel billets (including plain carbon, microalloyied and alloy steels), by far, represent the majority of hot-formed billets, although other materials including titanium, aluminum, copper, brass, bronze, and nickel are also induction heated for hot forming. Recent developments, common misassumptions, and innovative solutions in induction billet heating prior to hot forming are discussed here.

The main considerations when choosing an inductor style are the shape of the part, the desired heat-treat pattern, and the material handling to be used for production (i.e., how the part is moved into the coil or the coil indexes into the part, whether rotation of the part is required, or how is the part transferred after heat treatment). Over the years, induction practitioners have established a family of special or specialty inductors. Common names have been coined to describe their appearance or function, such as pancake, channel, hairpin, split-return, and butterfly inductors [1]. This column is devoted to the analysis and prevention of failures of split-return and butterfly-type inductors.
