Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
Rolling mill computer systems calculate setpoints for rolling using extremely complex mathematical models and send signals to engage the descale sprays and to bring the mill roll stands to speed and set the roll gaps. The rolling mill has six stands, numbered F1 F6 from south to north. Before rolling, the slabs are 55mm or 65mm thick.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
between the rolls and comparing the depth of the crease to determine whether the rolls are parallel or not. Check roll tram by visually sighting across the tops (or bottoms) of the rolls and compare how they line up with each other. On some machines it is possible to use a "tramming plate" to lay across the rolls .
