METHOD AND APPARATUS FOR MAKING COLD ROLLED METALLIC STRIPS OR SHEETS, METALLIC STRIPS OR SHEETS MADE BY SUCH METHOD

摘要

FIELD: rolled stock production. SUBSTANCE: method comprises steps of cold reduction of metallic strips or sheets at least between pair of rolling rolls. One rolling roll has textured working surface for transferring its relief on surface of rolled strip or sheet. Textured surface of rolling roll includes two-dimensional determined spot portions, each portion is in the form of crater surrounded by edge with normalized parameters of its surface. Rolled strip or sheet has reciprocal relief without waviness on its surface. EFFECT: enhanced quality of rolled piece surface designed for applying high-quality coating. 1 tb, 32 dwg
