Abstract
A crenellated resistor made from a carbonaceous material and having the shape of a hollow cylinder for use in furnaces working at high temperature. The resistor is characterized by the thickness of the cylinder walls which follows a profile determined so as to produce an even temperature on the surface of the resistor when it is working. Thus, the wall has a radial thickness which decreases in a transition section from the peripheral edge to the internal edge. The resistor configuration allows elimination of hot spots which may appear when electricity flows through the resistor.
