AI Technical Summary

Technical Problem

Vibrations during the rolling process cause striped patterns on the rolled material and rolling rolls, leading to reduced surface quality and increased roll grinding frequency, particularly in high-strength and thin materials under high loads, necessitating effective vibration suppression and measurement.

Method used

A roll unit with sensors located on the surface of chocks outside the bearing, easily replaceable and equipped with a storage device, allowing for efficient data acquisition and analysis to detect and mitigate vibrations.

Benefits of technology

Facilitates easier sensor replacement, improves work efficiency, reduces sensor failure probability, and enhances productivity by enabling early detection of abnormalities and optimizing roll replacement cycles.

Abstract

This roll unit comprises: a roll 100 configured to be capable of spinning about an axis of rotation; chocks 110, 110A and 110B respectively provided outward of both end portions, in an axial direction, of the roll 100; and sensors 120, 120A, 120B provided respectively on surfaces of the chocks 110, 110A and 110B, for acquiring information relating to the chocks 110, 110A and 110B. As a result, the present invention provides a roll unit equipped with a sensor that is easier to replace than in the past, roll equipment, a data measuring method, and a product manufacturing method.
