METHOD OF OPERATING FLATTING-MILL CHROMIUM-COATED ROLLS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metallurgy. Proposed method comprises alternating the roll operation in the mill and mechanical removal of roll body damaged layer in roughing as well as determining the roll body maximum wear before grinding. Irrational rolls consumption and accurate determination of roll surface depth to be removed are ensured by single measurement of roll body wear over its length to determine wear factor from maximum wear before roughing while wear calculated by the formula is set at every other roughing.EFFECT: higher efficiency, longer life.1 dwg, 1 ex
