DEMANDS TO A CHAMBER FURNACE FOR GAS OXINITRIDING

Essential demands to a chamber furnace for gas oxinitriding are presented. Its advantages versus non-continuously working furnaces are the prechamber, making possible a pre-and-after-treatment, the improved adjustment to the reaction gas composition e.g. by employing a solid electrolyte sensor and the improved safety technique. By using fibre isolation materials, energy consumption and furnace setting material may be reduced. The furnace design is well suitable for putting into practice waste-free gas circuits.
