Introduction
Coldrollingtechnologyiswidelyusedinvariousindustries,includingautomotive,aerospace,construction,andpackaging,amongothers.However,theperformanceofcoldrollingmillsislimitedbyvariousfactors,suchaslowspeed,highmaintenance,andlowefficiency.Toaddressthesechallenges,manyresearchersandmanufacturershavefocusedonimprovingthedesignandperformanceofcoldrollingmills,includingfour-highreversiblecoldrollingmills.Inthispaper,wewilldiscussthemodificationandupgradeofa300mmfour-highreversiblecoldrollingmill.
