Induction heating is widely used to heat metals prior to hot forming including forging, upsetting, rolling, extrusion, and other methods. Billets are heated either in cut lengths or continuously and are forged in presses, hammers, or upsetters, or are extruded. Steel components 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. The most popular billet-heating approaches are progressive multistage horizontal heating and static vertical or horizontal heating. This column focuses on the advantages and disadvantages of each.
