Work Roll Material Selection. The work rolls of rolling mill roll before rough rolling (R1): Work rolls before rough rolling must have toughness, wear resistance and thermal crack resistance. The hardness Mitsubishi Steel Corporation has developed a new type of high-chromium forged steel cold roll material. The test results show that the wear resistance of the cold roll with a Cr content of 10% is twice as high as that of a cold roll with a Cr content of 3%. When the Cr element content is further increased to 18%, the wear resistance of the coldCold rolling work rolls performance, material selection

Classification and material selection of metallurgical rolling mill rolls
The four-high reversing mill is the most widely used medium and heavy plate mill in modern times. It combines the advantages of the two-high and three-high Lauter mills, which not only reduces the rolling pressure, but also greatly enhances the rigidity of the rolling mill. The selection of rolls in this rolling mill has changed several times.Roll wear is a multiplex process where mechanical and thermal fatigue combines with impact, abrasion, adhesion and corrosion, which all depend on system interactions rather than material characteristics only. The situation is more complicated in section rolling because of the intricacy of roll geometry.Wear of hot rolling mill rolls: an overview ScienceDirect

Everything you need to know about rolling process
Rolling in metalworking is a metal forming process that helps to reduce the thickness of metal and make the thickness uniform. The metal stock is passed through one or more pairs of rolls to reduce the material. Rolling is classified according to the temperature of the metal rolled, it is a hot rolling if the temperature of the metal is aboveNowadays, the enabling technologies of smart manufacturing allow mitigating those problems [].They help in reducing mill vibration and material friction, to make higher the product quality, control the state of lubricant and temperature, and even save energy in terms of heat, vibration, and water flow control when it is used to keep the Applied Sciences Free Full-Text Smart Manufacturing in Rolling

Big Data as a Tool for Building a Predictive Model of Mill Roll
The predictive model of mill roll wear will allow rational use of rolls in terms of minimizing overall roll wear. Thus, the proposed model will make it possible to redistribute the existing workAbstract. The quality of cold-rolled aluminum products is dependent on a low surface roughness and a high surface finish. Accordingly, the present study develops a mixed lubrication model to examine the effects of the main rolling parameters. Cold rolling experiments are then performed on laboratory-scale high-speed cold mill system to Effects of operation parameters of cold rolling on surface
