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.
