Numerical model of induction heating of steel-tube ends

A two-dimensional model of induction heating of steel-tube ends, that takes into account magnetic induction saturation and temperature dependence of material properties is developed as an aid to process design and optimization. The model is solved by the finite difference method, and is validated by comparison with thermocouple measurements at an industrial facility at which three tubes are heated concurrently prior to an upsetting process. An example of the dependence of the final temperature distribution on geometrical parameters is discussed in detail.
