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 from the rolled bars ...

PDF Failures of Rolling Bearings in Bar and Rod Mill
Bar and rod mills can usually be found in the steelrolling process at a steelmaking plant. Preheated steel billets are rolled into the mill in order to produce channels, bars, rail beams, etc. The rolling stock is then forced into the grip of rolls, rotating in opposite directions. The two rolls, which are supported by rolling bearings, and a ...
