Title:SimulationStudyofInductionHeatinginTwo-RollRollingMillRolls
Abstract:
Thepurposeofthispaperistosimulatetheinductionheatingprocessintherollsofatwo-rollrollingmill.Inductionheatinghasgainedsignificantattentionasamethodforheatingmetallicbodiesduetoitsfastandefficientheatingcapabilities.Inthisstudy,wewillexploretheapplicationofinductionheatingintwo-rollrollingmills,specificallyfocusingontheheatingoftherollsusingelectromagneticinduction.
Introduction:
Thetwo-rollrollingmillisawidelyusedindustrialequipmentinthemetalworkingindustryforreducingthethicknessofmetalsheetsorshapingthemintospecificprofiles.Therollsinthemillplayacriticalroleintherollingprocess.Traditionally,therollsareheatedusinganexternalheatsourcesuchasgasoroilfurnaces.However,theseconventionalheatingmethodshavelimitationsintermsofenergyefficiencyandheatingspeed.
Inductionheating,ontheotherhand,offersamoreenergy-efficientandfasterheatingalternative.Ituseselectromagneticinductiontogenerateheatdirectlywithinthematerialbeingheated,eliminatingtheneedforphysicalcontactwithanexternalheatingmedium.Thetwo-rollrollingmilliswell-suitedforinductionheatingduetoitscompactdesignandabilitytoconfinethemagneticfieldrequiredforinduction.
Methodology:
Tosimulatetheinductionheatingprocessintherollsofatwo-rollrollingmill,wewilluseafiniteelementmethod(FEM)softwaresuchasCOMSOLMultiphysics.Thissoftwareallowsfortheaccuratemodelingandsimulationofelectromagneticandthermalphenomena.
