Abstract

Способ эксплуатации валков холодной прокатки, включающий чередование их работы в клети при допустимом количестве циклов нагружения, с перешлифовками со съемом поверхностного слоя бочки, отличающийся тем, что допустимое количество циклов нагружения определяют по увеличению твердости бочки на 3-5 единиц по Шору от первоначального значения, а съем при перешлифовке ведут до снижения твердости бочки до первоначального значения.The method of operation of cold rolling rolls, including the alternation of their work in the stand with an acceptable number of loading cycles, with resurfacing with removal of the surface layer of the barrel, characterized in that the permissible number of loading cycles is determined by increasing the hardness of the barrel by 3-5 Shore units from the original value, and removal during resurfacing lead to a decrease in the hardness of the barrel to its original value.
