Preventive Measures for Fatigue Cracking of Rollers -- Management, Maintenance and Use of Rollers

(1) It is practically impossible to completely eliminate the residual stress on the surface of the roller after grinding. It is necessary to measure the hardness value of each pair of rollers before and after grinding to conduct long-term tracking and master the performance status of the roller. This is conducive to timely revision of reasonable grinding processes. In addition, when the normally rolled roll is unloaded from the rolling mill,

Application of Simulation Technology in Roll Development

The purpose of simulation application is to improve process technology methods, improve product quality, master the process of cold bending molding, reduce roll repair and modification design, and save production debugging costs. The simulation of cold bending forming process cannot be separated from the experience of roller designers and the installation and debugging process of forming equipment. The simulation without experience and process knowledge of cold bending forming process is meaningless and can have serious consequences in practical applications.
