The Application of High Power Transverse Flux Induction Heating in the Metal Strip Industries

摘要

Davy International has developed a Variable Width Transverse Flux Induction Heating system for strip metals, registered trade name TFX, based on licensed technology from EA Technology, Capenhurst. As outlined by Ronald A Walker and Adrian Hayward, evolution of the current design has spanned two 1700mm wide multi-megawatt Production installations on aluminium, a 350mm wide pilot line for copper and brass and a 500mm pilot line for a range of carbon steels. The Variable Width Inductor design uses a rigid, solid coil/core assembly which has proven in service to be necessary for long term reliability and adjustable duple modifier packs on each pole to control the distribution of magnetic flux at the strip edges giving a uniform cross strip temperature profile.
