ABSTRACT:
A resistance heating element of the ribbon type for use in a high temperature electric furnace. The element has the same curved cross-sectional configuration throughout its entire length to give it strength and stiffness and permits the element to be bent into various patterns without any overlapping portions at the bends. The curved cross-section permits the element to be supported at the bends without the element sagging reducing the amount of heat absorption by the supports and allowing greater exposure of the element.
