-——————————————————————————————————————————————————– A typical heat treatment procedure for induction hardening involves heating the component or its selected areas to the austenizing temperature, then rapidly cooling the alloy below the martensite start temperature. Figure. 1 (above), shows a cross section of cup-shaped workpiece. Figure. 2 (below), shows results of FEA (Finite Element Analysis) computer simulation of induction heating [...]
In order to acheive uniform heating when brazing dissimilar materials, the inductor design should provide compensation for the differences in heating characteristics of each component. click here to read more.
Non-uniform coil current distribution resulting from various electromagnetic phenomena has a dramatic effect on induction coil life and crack development in the coil copper. This article is one of series of articles devoted to a systematic scientific/engineering analysis of failures of induction heating coils and prevention. Article concentrates on coil copper electromagnetic edge effect, effect [...]
Whenever someone is talking about induction heating, reference is often made to the phenomenon of skin effect. In most publications devoted to induction heating distributions of current density and power density (heat source distributions) along the workpiece thickness/radius are simplified, and described as exponentially decreasing from the surface into the workpiece. However, in some applications, [...]
