2007-11-23.1 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.
2019-12-21The 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.
The number of back- up rolls high as 20 or more depends upon the support heeded for the working roll. It cluster mill is used for cold rolling process. Application of rolling process Hot rolled product such as concrete reinforcing bars, plates, wire rods, sheet and strip, rails, structural.
