Abstract

본 발명은 냉간압연에서의 제어량과 판두께 편차를 줄이고자 발명한 판두께 편찰를 줄일 수 있는 냉간압연 방법에 관한 것으로 냉간압연시 연간압연실적 데이타를 직접이용하는 대신 산세탱크(2)에서 산세공정을 거친 후 냉각압연직전의 냉각압연판(6) 두께를 산세출측두께 측정기(5)에서 측정하여 이 측정데이타를 A/D변환기(3)을 통해 주 전산기(4)에 입력하고 이와같이 입력받은 주 전산기(4)는 상기 측정데이타를 연속냉간 압연기(8)에 전달하여 최종제품의 두께 편차를 줄일 수 있도록 한 것이다.The present invention relates to a cold rolling method that can reduce the plate thickness deviation invented to reduce the control amount and plate thickness variation in cold rolling, and the pickling process in the pickling tank (2) instead of directly using annual rolling performance data during cold rolling. After roughing, the thickness of the cold rolled plate 6 immediately before cold rolling is measured by the acid-extraction-side thickness meter (5), and the measured data is inputted to the main computer (4) through the A / D converter (3). Computer 4 is to transmit the measurement data to the continuous cold rolling mill 8 to reduce the thickness variation of the final product.
