During annealing, heat transfer within steel coils is complicated by the different conductivity in radial and axial directions due to small air gaps between the steel layers in the radial direction. Here an analytic solution augmented with numerical calculations illustrates some of the fundamental behaviour of the system, including calculations of the time lag. The beneficial effects of additional heating on the curved surfaces are shown.
