Recently the new induction concepts for through heating of aluminium billets before extrusion have been proposed and some installations are under successful operating in industry. The paper is devoted to consider these concepts, their advantages and perspective. The aspect of numerical modeling as a necessary tool to design the induction heating installation is described in the paper and result...

The paper is devoted to investigation of the induction system for billet heating by rotation in DC magnetic field. Induction heating of aluminium billets by rotation in DC magnetic field produced by superconductive coils is an innovative technique. The efficiency of the heater is expected to be up to 90 %. Three-dimensional numerical code based on Finite element method has been developed to inv...

This paper numerically investigates the application induction heating in weld-based additive manufacturing to reduce residual stresses. To avoid time-consuming transient electromagnetic calculation, the induction heat is assumed to be constant in the arc coordinate. Thermo-electromagnetic coupling analysis is performed only at a typical time to obtain the representative distribution of inductio...

To observe the evolution mechanism of physical fields in welding deformation rectification process by a traveling induction heating, research on simulation models welding—induction heating continuous were carried out. High-strength steel plates selected for experiment and turn, stress field strain distribution after various processes measured recorded. Then, according to construction process, a...
