AI Technical Summary
Technical Problem
The lack of standard data reference in the existing technology of roll grinding process leads to repeated adjustment of grinding parameters, which affects grinding efficiency and is prone to defects such as tool marks, vibration marks, and oblique marks.
Method used
By statistically analyzing daily grinding parameters using big data, and combining different grinding wheel diameter ranges and roll materials, precise grinding parameters and process sequences are set, including adjusting transverse speed, grinding wheel dressing, grinding pressure, and constant current gain, to avoid defects.
Benefits of technology
This technology improves grinding efficiency and precisely controls roll roughness without introducing defects, thus ensuring grinding quality.

Abstract
This invention discloses a method, system, and apparatus for controlling the roughness of a rolling mill roll. The apparatus includes rough grinding, intermediate grinding, a first fine grinding, a second fine grinding, a third fine grinding, and measurements of roll shape and roundness. Based on preset grinding parameters, when the roughness of the ground roll exceeds a target roughness, the apparatus performs intermediate grinding for a first preset number of passes. After performing one fine grinding pass, it returns to the intermediate grinding stage to perform the remaining passes. During the third fine grinding step, when performing a second preset number of passes, the number of fine grinding passes is adjusted based on the measured roughness and a preset strategy. By establishing reference grinding parameters and making adjustments based on these parameters, grinding efficiency is improved without inducing defects.
