S.A. du Four Electrique Delemont Delemont, Switzerland system integrated High carburizing power. High efficiency. Space saving. Simple setting-up. takes place in a retort mounted The methanol (and in some cases the nitrogen) are stocked extern- ally and injected through a distri- bution circuit comprising control This atmosphere can be used for carburizing by adding propane adding ammonia. Heating of the retort is adjustable separately; it does not influence trolled within strict limits and maintained at the required value. The Injector-M system is fitted as tinuous furnaces of types T and Vi, with or without turbo-circu- The system capacity is adapted cess. An interesting alternative and reproductible quality guar- antee the best treatment results (hardening, carboni-

(methylic alcohol) This alcohol is obtained by catalytic oxide catalytic reaction of carbon- These processes have greatly improved the purity and the regular- ity of the product quality, which was previously obtained by distillation of wood. A typical analysis now shows After dissociation a perfect stable gas composition is obtained, ideal for the protection of metals against oxidizing or decarburizing, as well as Vapour pressure at 20 °C: 96 Torr With the Injector-M system, the intrinsic carbon content of the entails that safety rules and regu- lations are respected.
