압연롤의 편심 측정장치 및 측정방법

Apparatus and method for measuring roll eccentricity in rolling roll

Abstract

PURPOSE: An apparatus and a method for measuring eccentricity of a rolling roll are provided to measure the eccentricity of the rolling roll using an image of a measured object instead of the shape of the rolling roll. CONSTITUTION: An apparatus for measuring eccentricity of a rolling roll includes a measured object(5), a camera(6), and a calculator(7). The measured object is fixed to the center of a work side section of a rolling roll(1). The camera is set opposite to the measured object and acquires an image of the measured object. The calculator measures eccentricity of the rolling roll by comparing images of the measured object, respectively acquired from the camera when the rolling roll is stopped and rotated. The camera acquires a blurring image of the measured object according to low-speed shuttering when the rolling roll is rotated.
압연롤의 비정상적인 편심을 측정하기 위한 압연롤의 편심 측정장치와 측정방법이 개시된다. 압연롤의 편심 측정장치와 측정방법은 압연롤의 워크사이드 단면 중앙에 고정되는 피측정체와 마주보도록 카메라를 설치하고, 카메라로부터 획득되는 피측정체의 정지 및 회전 영상을 연산장치에서 비교하여 압연롤의 편심을 측정한다. 따라서 압연롤 자체의 형상이 아닌 압연롤에 고정되는 피측정체로부터 압연롤의 편심을 간편하게 측정할 수 있다. 압연롤, 편심, 피측정체, 카메라, 연산장치
