Title
(KO) 냉간 압연기의 채터링 검출 방법, 냉간 압연기의 채터링 검출 장치, 냉간 압연 방법, 및 냉간 압연기
Abstract
(KO)
본 발명에 관한 냉간 압연기의 채터링 검출 방법은 냉간 압연기의 진동을 측정하는 측정 스텝과, 측정 스텝에 있어서 측정된 진동의 시간 파형에 대해, 주기적인 진동이 집속되지 않고 계속되는 시간과 동등 이하의 소정 주기에서 주파수 해석을 실행하는 것에 의해, 진동 강도의 시간 파형을 산출하는 산출 스텝과, 산출 스텝에 있어서 산출된 진동 강도의 시간 파형에 포함되는 진동 강도가 소정의 임계값보다 큰 점의 수에 의거하여, 냉간 압연기의 채터링의 전조 진동을 검출하는 전조 진동 판정 스텝을 포함한다.
