Hot-rolling •The first hot-working operation for most steel products is done on the primary roughing mill •These mills are normally two-high reversing mills with 0.6-1.4 m diameter rolls (designated by size). •The objective is to breakdown the cast ingot into blooms or slabs for subsequent finishing into bars, plate or sheet.

Rolling is a common metalworking process used during the production of steel. It involves passing a sheet of steel through multiple rollers. Some rolling processes use two rollers, whereas others use four …

3.1 Key Feature of Process Control: Detection of Periodic Defects Rolls and rollers are the most heavily used parts of a rolling mill. Due to wear from contacting hot material with great force, their lifetime is limited. Although rolls are refurbished in the roll shop regularly, they occasionally crack before the end of the usual production cycle.

Rolling is the most important metal forming process. More than 95% of ferrous and non-ferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. 1.1 and Fig. 1.2.
