#CMT# #/CMT# The apparatus has an electromagnetic screen (6) formed of an electricity conducting material e.g. copper. Magneto-dielectric field concentrators (3) having a concave shape (3a) distributes power to a surface of support cone (2), where the magnetic field is guided on external parts of an multi-zone inductor (5) by the concentrators or laminated sheets. The concentrators are combined with the screen. #CMT#USE : #/CMT# Induction heating apparatus for bracing and unbracing a steel cutting tool e.g. helve ring. #CMT#ADVANTAGE : #/CMT# The electromagnetic screen formed of the electricity conducting material e.g. copper, protects a steel cutting tool from magnetic field effects, thus heating the support cone without the need for heating the tool in order to unbrace the tool, while ensuring resistance to heat and shocks. The utilization of magneto-dielectric field concentrators and the inductor optimizes or improves distribution of power to the surface of the cone. The magneto-dielectric concentrators are combined with the screen, thus improving homogeneity of temperature of the cone of the tool, and hence improving longevity of the tool by eliminating overheating zones. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an assembly view of an induction heating apparatus. 1 : Steel cutting tool 2 : Support cone 3 : Magneto-dielectric field concentrators 3a : Concave shape 3b : Upper surface 5 : Multi-zone inductor 6 : Electromagnetic screen. |
