Induction Heating with Rotating Permanent Magnets: Experimental Results on an Industrial Installation

摘要

MAGNHEAT is a LIFE project proposed to demonstrate the possibility of industrial application of a new technology for the induction heating of aluminum billets before extrusion. This technology uses Permanent Magnet Heaters (PMH), which constitute a high efficiency solution for the heating of high conductive metals. The paper briefly describes the main steps of the project: the design of the Permanent Magnet Heater, the realization and installation of the demonstrator on an extrusion production line of Pandolfo Alluminio S.p.A. and the performance of the system.
