轧辊偏移条件下六辊轧机的板形调控特性
Shape-control characteristics of six-high mill with roll offset
摘要
Abstract
To improve the stability of the six-high cold rolling mill, the roll offset method is often used. This paper uses ABAQUS finite element software to establish the rolls-strip coupling model. The study analyzes typical roll systems with different roll offsets to determine the effect of different roll offsets on the shape-control characteristics of the six-high cold rolling mill. Specifically, the results show that when the intermediate roll offset is positive, the bending force of the work rolls has the best control effect on the quadratic crown, as well as great influence on the quartic crown. For the four roll offsets used, the efficiency of the bending force of the interme-diate rolls on the quadratic and quartic crowns of the strip is almost the same, ranging from 0-300 kN. When the intermediate roll off-set is positive, the bending force of the intermediate rolls has the best control effect on the quadratic crown, ranging from 300-500 kN. When the work roll offset is positive, the bending force of the intermediate rolls also has a great influence on the quartic crown. The controlling tendencies of the shift of the intermediate roll on the quadratic crown are almost the same for different roll offsets, and the efficiency of negative roll shifting on the quadratic crown is better than that of positive roll shifting. Intermediate roll shifting also has a great influence on the quartic crown when the work rolls are offset.关键词
