Rolling of steel is normally the first step in the processing of steel after it is made and cast in a steel melting shop. The initial rolling of steel is done in a hot rolling mill where slabs, blooms, and billets are rolled down to different rolled products such as plates, sheets, strips, structures, rails, bars, rods, and merchant products.

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 from the rolled bars ...
