FIELD: metallurgy.
SUBSTANCE: method includes alternation of cyclic loadings of roll and at its operation in stand with regrinding. Excluding of shaft flake at rational usage of effective layer of its surface is provided ensured by acceptable number of cycles loading is defined by increasing of barrel hardness for 3-5 units by Shore from initial value, and removal at refacing is implemented up to reduction of barrel hardness up to initial value.
EFFECT: increasing of rollers resistance of stands for cold rolling of sheet metal.
