Online roller shape detection device and method

Abstract

The invention provides an online roller shape detection device and method. The device comprises a sensor array and a calculation module connected with the sensor array. The detection face of the sensor array points to and is parallel to a hot roller. Multiple detection stations are evenly arranged on the sensor detection face along the straight line. Distance sensors are arranged at the detectionstations. The calculation module stores position coordinates of the detection stations on the detection face and further stores the initial detection distance L0 between the surface of the roller andthe detection stations when the roller does not work, and the calculation module further stores the included angle theta between the detection signal direction of the distance sensors and the horizontal plane. When the roller shape of the roller in the operating state is detected, the distance sensors detect the real-time distance Lx between the surface of the roller and the detection station according to the preset frequency, the calculation module calculates the current roller diameter corresponding to each detection station according to L0 and Lx, and the roller diameter data measured by the detection stations and the position coordinates of the detection stations on the detection face are associated so as to solve a roller shape curve. By means of the online roller shape detection device and method, the roller shape can be detected in real time.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an online roll shape detection device and a method thereof. Background technique [0002] At present, there are no patents at home and abroad related to the related devices and technologies of how to detect the roll shape of hot rolling rolls online, which can only be detected offline before or after the use of the rolls. [0003] But in fact, the roll shape of hot rolling is extremely important to the production control process of hot rolling. The roll shape during rolling determines the transverse thickness distribution, thickness difference, and crown of the aluminum alloy strip during rolling. For example, if the roll shape during rolling is a convex roll type, then, correspondingly, the plate shape is convex and concave; if the roll shape during rolling is concave roll type, correspondingly, the plate shape is convex degree is convex. Generally speaking, in ...

Problems solved by technology

Because in the actual rolling process, the change of the roll shape caused by the above factors cannot be measured and monitored in real time, and the general theoretical calculation cannot completely match the change of the actual roll shape
