Abstract
PURPOSE: To perform shape leveling surely at high speeds by specifying the line speed and the work roll diameter of the 1st roller set of a tension leveler which treats a steel strip of a full hardening material after cold rolling.
CONSTITUTION: The work roll diameter Dmm of the 1st roller set of a tension leveler which makes shape leveling of a steel strip of a full hardening material which remains as cold rolled and is not annealed, at high speeds of ≥600m/min. is so selected as to satisfy the formula. Here, the gage of the steel strip is defined as (t)mm, the deformation resistance thereof as YSkg/mm and a line speed as LSm/min. The relations between these and shape goodness are as shown in the figure. At LS<600, the slope is small and there is no need for changing D despite changing of LS. At LS≥600, the slope is large and there is a need for changing D. Now, if ≤1.2% acuteness is defined as acceptance in the criteria after the shape leveling and the acceptance line of the figure of LS≥600 is approximated, it reveals that satisfactory result is obtainable if D satisfies the formula.
