摘要:
An apparatus and a process for the production at high capacity of high purity powders from a large diameter wire or rod using a combination of plasma torches and induction heating are disclosed. The process provides a superior productivity, by incorporating a more effective inductive preheating system. A mechanism is also included in the apparatus, which allows adjusting the position of the plasma torches and their angle of attack with respect to the wire, which has a direct effect on the mechanical and thermal energy transfer from the plasma plume to the wire, allowing a fine control over the particle size distribution as well as the production capacity. Furthermore, varying the induction frequency allows for the optimization of the temperature profile inside the wire, which can be directly correlated to the resulting mean particle size.

摘要:
An apparatus and process are provided for inductively heating a workpiece to a desired cross sectional temperature. At least one pair of coils form a transverse flux inductor. The workpiece is located between the pair of opposing coils, which are oriented across the cross section of the workpiece. Each coil comprises a plurality of coil sections. The distance between one or more opposing coil sections is adapted to achieve the desired cross sectional induction heating temperature profile in the workpiece. Alternatively the distance between all opposing coil sections are equidistant from each other, and one or more flux concentrators, moveable at least in a direction perpendicular to the surface of the workpiece, can be used to achieve the desired cross sectional induction heating temperature profile in the workpiece.
