Fig. 1.7.1: Rolling mill control From the above curves, we could understand the control of rolling mill. The solid curve, called plastic curve, represents the variation of rolling load with rolled thickness. As thickness reduces, roll force increases. This was shown earlier. The solid line represents the elastic deformation of the roll.

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

performed on Light section rolling mill SKET φ370mm from 34,8mm to 4,3mm of thickness (8 passes), and Laboratory light section rolling mill φ250mm from 4,3mm to 2,3mm of thickness (3 passes). The relative total height reduction for the first eight passes is 87,7%, the relative total height reduction for the last three passes is 46,5%.

Shape rolling is a continuous high productive metal- forming process, which enables the manufacturing of long workpieces with uniform cross-sections by applying plastic forces exerted through a set of grooved rolls [1, 2].As both the rolling energy consumption and the quality of rolled work-piece are heavily dependent on the section …

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 …
