Abstract

Improvements in the construction of vertical ovens, characterized in that each oven is equipped with: a carefully insulated vertical muffle, in which the pieces to be treated are suspended in a vertical position; heating and cooling installations of a thermal fluid consisting of solid particles; means for lifting said particles, heated or cooled, to the upper part of the furnace and for injecting them into said muffle where they descend by gravity bathing the parts to be treated and means for regulating the flow rate of the thermal fluid.
