Abstract
Description
Claims (5)
- 금속판의 냉간 탠덤 압연에 있어서 압연 윤활을, 압연유와 물을 혼합한 소정의 일종의 에멀젼 윤활유를 각 압연 스탠드 입구 측에서 노즐로부터 공급하여 실시하는 냉간 압연에 있어서의 윤활유 공급 방법에 있어서, 윤활 노즐 압력을 측정 또는 추정하고, 적어도 상기 소정의 에멀젼 윤활유에서는 윤활 과다가 일어나기 쉬운 압연 스탠드의 윤활 노즐 압력을 0.5 MPa 이상이 되도록 압력 제어하면서, 해당 스탠드의 롤 바이트 입구에 상기 윤활유를 직접 분사하여 공급하는 것을 특징으로 하는 냉간 압연에 있어서의 윤활유 공급 방법. 다만, 윤활 노즐 압력이란 윤활 노즐 배관 중에서의 압력이다.
- 제1항에 있어서, 각 압연 스탠드마다 저압력용 노즐과 고압력용 노즐을 한 쌍으로 한 윤활 노즐을 복수 대 배치하는 동시에 각 압연 스탠드의 압연 속도에 따라서 필요한 윤활 조건을 상기 소정의 에멀젼 윤활유를 사용한 경우에 달성할 수 있도록, 각 압연 스탠드마다 저압력용 노즐 또는 고압력용 노즐 중 어느 하나 또는 쌍방을 사용하는 것을 특징으로 하는 냉간 압연에 있어서의 윤활유 공급 방법.
- 제1항 또는 제2항에 있어서, 상기 윤활 노즐 압력의 제어에 따른 윤활유 공급량의 증감을 상쇄하도록, 상기 스탠드에서 사용하는 윤활 노즐 개수를 조정하는 것을 특징으로 하는 냉간 압연에 있어서의 윤활유 공급 방법.
- 제1항 또는 제2항에 있어서, 상기 윤활 노즐 압력의 제어를 실시하더라도, 윤활유의 공급량을 일정하게 제어하는 것이 가능한 윤활 노즐을 사용하는 것을 특징으로 하는 냉간 압연에 있어서의 윤활유 공급 방법
- 제1항 내지 제4항 중 어느 한 항에 있어서, 상기 윤활 노즐 압력을 피압연재인 상기 금속판 스트립의 상하면에서 따로따로 제어하는 것을 특징으로 하는 냉간 압연에 있어서의 윤활유 공급 방법.
