Abstract
In a cylindrical elongated furnace for treating materials at high temperature in a gaseous atmosphere under high pressure, there is a vertical cylindrical pressure chamber forming a furnace space surrounded by a cylindrical heater, with an insulating sheath around the furnace space and the heater formed of a number of metal tubes with insulation between them. At least one of the metal tubes is suspended from a supporting member at the upper part of the insulating sheath and is provided at its lower part with a number of slots extending upwardly from the bottom edge.
