Abstract

본 발명은 연속식 열간압연기상에서 레벨링 오류에 의한 판파단 사고를 방지하는 방법에 관한 것으로서, 루퍼롤(1)의 양쪽 선단에 설치한 위치센서 및 하중센서로 루퍼롤(1)의 위치편차를 검출하여 한쪽 롤 간격에서 다른쪽 롤간격을 뺀 값(D2)에 비례치(C)를 곱한 값으로 양쪽롤 간격의 조정범위를 정하여 비례제어로 통판량의 폭방향 분포를 제어함으로써 기존의 연속식 열간압연기에서는 통판안정성을 감시하기 위한 별도의 운전자가 필요하나 본 발명을 채용할 경우 이를 자동화하여 운전자의 수를 줄일 수 있고, 운전자의 육안감시에 의해서는 검출될 수 없는 루퍼양쪽의 부하편차로만 나타나는 내재된 사고위험까지도 없앨 수 있는 장점이 있는 유압루퍼를 이용한 롤레벨링시스템의 폭방향 통판량 제어방법이다.The present invention relates to a method of preventing a plate breaking accident due to a leveling error on a continuous hot rolling mill, and detects the positional deviation of the looper roll (1) by a position sensor and a load sensor installed at both ends of the looper roll (1). To adjust the width range of both rolls by proportional control by multiplying the roll distance from one roll interval by the value of (D 2 ) by the proportional value (C). In the hot rolling mill, a separate driver is required for monitoring the mail order stability. However, when the present invention is adopted, the number of drivers can be reduced by automating the present invention. It is a width control method of roll leveling system using a hydraulic looper that has the advantage of eliminating the inherent accident risk.

제2도는 유압루퍼롤의 구조도, 제3도는 본 발명을 채용한 롤레벨링시스템의 개념도이다.2 is a structural diagram of a hydraulic looper roll, and FIG. 3 is a conceptual diagram of a roll leveling system employing the present invention.

Claims (1)

루퍼롤(1)의 양쪽 선단에 설치한 위치센서 및 하중센서로 루퍼롤(1)의 위치편차를 검출하여 한쪽 롤 간격에서 다른쪽 롤간격을 뺀 값(D2)에 비례치(C)를 곱한 값으로 양쪽롤 간격의 조정범위를 정하여 비례제어로 통판량의 폭방향 분포를 제어하는 것을 특징으로 하는 유압루퍼롤을 이용한 롤레벨링시스템의 폭방향 통판량 제어방법.A position sensor and a load sensor installed at both ends of the looper roll (1) detect the positional deviation of the looper roll (1), and the proportional value (C) is added to the value (D 2 ) obtained by subtracting the roll gap from the other roll interval. A method for controlling the width direction of a roll leveling system using a hydraulic looper roll, characterized in that to control the width direction distribution of the plate quantity by proportional control by setting the adjustment range of both roll intervals by the multiplied value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
