Experience in the use of endogenerators and the use of new catalysts

  • 17 Accesses

Conclusions

  1. 1.

    To produce an endothermic atmosphere for gas carburizing and carbonitriding it is desirable to use straight-flow type endogenerators with a retort inside diameter of 160–200 mm in the center of which are placed 50–70-diameter tubes.

  2. 2.

    The catalyst must be located in zones of good heating.

  3. 3.

    To avoid the formation of carbon soot, the outlet from the endogenerator must be cooled intensely.
