METHOD OF ELECTRIC RESISTANCE HEATING OF METAL PARTS

摘要

1. A method for direct electric resistance heating of metallic workpieces where, in addition to this, a temperature influence perpendicularly to the direction of current flow is effected by energy offers from outside within specific periods, characterized in that defined energy offers act for such a short time that no temperature compensation takes place across the section of the workpiece within these periods and, consequently, the temperature distribution perpendicularly to the direction of current flow is non-uniform.
