of rolling mills

A four high rolling mill is used for the hot rolling of armor and other plates as well as cold rolling of plates sheets and strips 4 Tandem rolling mills It is a set of two or three stands of roll It begins with comprehensive coverage of rolling processes and the mechanics of rolling which is the theoretical content of the subject This is followed by a chapter on 'rolling practices' that highlights plant level procedures and practices employed by the rollers for producing desired products

A BASIC UNDERSTANDING OF THE
MECHANICS OF ROLLING

After a roll change or a mill stop rolls need some time to return to stable thermal conditions every new bar entering the mill creates an impact and sometimes there are really severe rolling accidents due to faults by operators weak rolled materials with internal defects or becauseMay 22 1973FIGS 1 and 1A constitute a composite top plan view partially in section of one form of rolling mill stand together with a roll changing arrangement therefor FIG 2 is a side elevational view partially in section of the equipment shown in FIG 2
