Given that aluminum and its alloys offer numerous advantages over many other metals, it is not surprising that inquiries about induction billet-heating equipment increasingly involve the heating of aluminum alloys.
Understanding induction heating efficiency and how it can be improved is critical for forgers pursuing the reduction of energy consumption and cost. This article presents a basic mathematical explanation of induction heating efficiency and discusses a variety of practical approaches to maximizing it.
In some applications, such as the forming of tie-rod heads, only the end regions of the workpiece need to be heated for subsequent deformation. Induction end-heating systems of all coil types are more sensitive to electromagnetic and thermal non-uniformities that are innate to the induction heating process.
