  • Method for the inductive heating of a refractory mold part as well as corresponding mold part for such
    Patent number: 6148903
    Abstract: A refractory guide member and a method for heating the refractory guide member by use of an inductor, where at least one collateral electromagnetic field located in a region spaced apart from the inductor is generated by the inductor. The mold part is made of an electrically conductive layer with several insulating interrupting slots for the controlled deflection of eddy currents from a main field generated by the inductor into a region spaced apart from the inductor.
    Type: Grant
    Filed: February 24, 1999
    Date of Patent: November 21, 2000
    Assignee: Didier-Werke AG
