Conclusions

  1. 1.

    In manufacturing cold-rolled electrical sheet with heat resistant coatings it is advisable to improve the surface finish before application of the coating, since it has a considerable effect on the microrelief after high-temperature annealing.

  2. 2.

    With magnesia coatings applied before high-temperature annealing the microrelief depends on the original finish, although the grade of the finish remains unchanged. A phosphate coating has no substantial effect on the microrelief.

  3. 3.

    The unevenness of the microrelief on commercial cold-rolled electrical sheet with magnesia and phosphate coatings is somewhat higher than that for “Karlit” coatings.
