Analysis of roll deformation for sendzimir rolling mill
젠지미어 압연기 롤 변형해석
Abstract
Sendzimir rolling mill is widely used for rolling hard materials such as stainless steel due to its small work roll diameter and shape controllability using two effective actuators, AS-U-Roll crown adjustment and lst. intermediate roll shifting. However, in comparison with 4-high or 6-high mills, it is noteasy to get good strip or excellent flatness because Z-mill has small diameter of work rolls which are easily deformed by load. A new mathematical model based on the method of dividing roll and strip into multo-portions was used to develop strip profile prediction software. Using the developed software, several influencing factors related to rolled strip profile for Z-Mill were tested analytically and characterized for the effective shape control. The effects of adjusting shape control actuators of Z-Mill on strip profile were also examined and discussed in detail.
본 연구에서는 Z-Mill의 압연판 형상 예측을 위한 이론 및 컴퓨터 시뮬레이션 에 관한 사항과 설비조건, 압연조건, 소재조건이 판형상에 미치는 영향에 대해 논하고 자 한다.
