Conclusions

  1. 1.

    Chemically pure magnesium fluoride is the most effective deoxidizing agent for salt baths operating at 1200–1300o.

     
  2. 2.

    It is expedient to deoxidize the bath only once per shift.

     
  3. 3.

    The use of a chromomagnesite lining and electrodes of steel 10 increases the service life of the bath to 25 days and reduces the decarburizing activity.

     
  4. 4.

    The use of electrodes made of heat resistant alloy and a lining of chromomagnesite bricks increases the service life of the salt baths to 140–145 days.
