Abstract
FIELD: rolling. SUBSTANCE: in process of dressing residual curvature is measured after each pass, is compared with permissible curvature and positions of working rollers are corrected in agreement with value of residual curvature of rolled stock found in sections 1 located at distance t< l < 3t+tfrom butts of rolled stock, where tis length of irregular end, tis length of free from momentum zone. Before dressing ranges of permissible moments of rolled stock bending in free from momentum zones corresponding to permissible curvature in sections 1 are found. In process of dressing pressure on working rollers is measured, actual bending moments are determined and positions of working rollers are corrected by results of comparison of actual and design bending moments. EFFECT: simplified process of control over dressing. 3 cl, 1 dwg
