Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    The conditions were established for rapid spheroidizing annealing of roller bearings made of steel ShKh15 with use of induction heating.

  2. 2.

    As compared with the treatments used in bearing factories, the new treatment has the following advantages:

  1. a)

    The spheroidizing annealing time is reduced from 10–20 h to 3 min;

  2. b)

    Conditions are created for mechanization and automation of the heat treatment for roller bearings so that it can be conducted in the production line;

  3. c)

    Rapid annealing of steel ShKh15 with induction heating makes it possible to obtain a highly dispersed structure of sorbite-like pearlite;

  4. d)

    The quality and service life of roller bearings increase due to the more dispersed structure, and decarburization decreases due to rapid induction heating.
