Analysis of Chip Generation During Bar Rolling | SpringerLink
· Bar rolling is a semicontinuous rolling process involving a series of rollers, where a cast billet is shaped into the final TMT bar. In these mills, lowthickness bar rolling (< 20 mm) is prone to cobbles, due to several operational reasons, which affects productivity. One major contributor is blockage of slitters and notwist mill grooves due to excessive chip formation .
