A furnace to be heated to a high temperature which employs heating elements made from carbon or graphite. A longitudinal space within the furnace for accommodating said heating elements and a furnace bed for the transportation of articles to be treated through the furnace, is formed solely by blocks of porous carbon and without the emplyment of a conventionally prerequisite protective case. A pair of the heating elements extend along inner lateral walls of said space, facing to each other with the furnace bed therebetween, and have their electric termina...
A high temperature heating furnace having therein carbon or graphite heating elements operative to heat the interior of said furnace to a temperature range of approximately 2000°C. to 3000°C., and which comprises a frame, a liner having therethrough a space extending longitudinally throughout a longitudinal distance of the furnace for passing therethrough articles to be treated by the furnace, said liner being formed within said frame by thermal insulation blocks having internal surfaces facing upon and defining said space, and being made from porous car...
