Abstract

제철소의 열간압연공정에서 압연시 슬라브소재가 사행 또는 캠버발생으로 각종 불량발생의 원인이 되고 있다.In the hot rolling process of steel mills, slab materials are meandering or cambers, causing various defects.

본 발명은 압연기에 슬라브소재의 폭 계측기(11)을 설치하고 사이드가이드부에 광센서를 설치하여 이들로부터 공급된 데이터신호를 마이크로프로세서(50)에서 연산후 슬라브소재가 중앙에 정확히 배열토록 사이드가이드를 유압서보시스템으로 강제 조정하였다. 그리고 안정조업을 위해 기존 사용중인 전동기와 감속기에 의한 시스템을 게속 사용하기 위하여 클러치를 매개로 전동기의 동력전달이 가능토록 하여 유압서보시스템의 이상이 있다하여도 조업중단없이 작업이 계속될 수 있도록 2원화 시스템을 구성하였다.In the present invention, the width measuring device 11 of the slab material is installed in the rolling mill, and the optical sensor is installed in the side guide part. Was forced to a hydraulic servo system. In order to continue to use the system by the existing motor and reducer for stable operation, the power transmission of the motor is possible through the clutch, so that the work can be continued without any interruption of the hydraulic servo system. The original system was configured.

따라서 압연시 발생되는 각종 문제를 연속자동제어하여 생산품의 고품질화를 꾀할 수 있게 되었다.Therefore, it is possible to achieve high quality of the product by continuously controlling various problems generated during rolling.
