In-Depth Induction Heating of Large Steel Slabs by Means of a DC Saturating Field Produced by Superconducting Coils

The feasibility of an innovative in-depth AC induction heating method for large steel slabs is investigated. Aside from the AC field, which induces the heating currents, a large DC magnetic field is also applied, which brings the material to saturation. Due to saturation, permeability is reduced by orders of magnitude and the penetration depth is drastically increased, thus enabling much faster an...
