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 …
