The material properties of the strip play a vital role in the power consumption and the damage evolution in a tandem cold rolling mill. Therefore, the strip tearing or power consumption level of importance is not the same for different materials. Besides, various reduction schedules can be proposed for the specified total reduction and initial strip …

Bar rolling is a semi-continuous rolling process involving a series of rollers, where a cast billet is shaped into the final TMT bar. In these mills, low-thickness bar rolling (< 20 mm) is prone to cobbles, due to several operational reasons, which affects productivity. One major contributor is blockage of slitters and no-twist mill grooves due to …
Since the seventies, six-high mill technology has been introduced in several hot and cold rolling plants. Its main advantage in comparison to the classical four-high mill is its large range of mechanical shape control. Thus, the effective roll gap is significantly influenced by work and intermediate roll bending and intermediate roll shifting.
