This paper presents a constructive solution for a heating furnace used at heat treatment of aluminum alloys. Therefore, i choosed a typical charge of parts for studieing the heating equipment. The studies that I have done can reveal the advantage of using the ceramics for furnace insulation. In this paper I propose a modified form of the work chamber and some new solutions for some parts of the furnace, in order to provide a higher temperature uniformity (±2°C) in the furnace.
