  1. 1.

    The control and automation of the preparation of the necessary protective and case hardening atmospheres should be based on the concentration of oxygen in the mixture supplied to the chamber for partial mixing and correction of the programmed air-gas ratio (or technical nitrogen-gas ratio) when the requirement for the composition of the controlled atmosphere and the properties (heat producing capacity) of the initial gas vary.

  2. 2.

    The quantitative indices of the process can be determined by the nitrogen balance.
