Electric furnaces with carbon radiator

A type of electric furnace for application to metallurgy and to operations at very high temperatures has been developed in which the heat producing element is a carbon electrode raised to a very high temperature and conveying heat to the charge by radiation. Furnaces of this type, which have incorporated in them a number of novel features, have been devised and perfected in France in the electrothermic laboratory of the company with which the author is connected.
