自动轧管机轧管时的壁厚控制方法 Title:WallThicknessControlMethodsinAutomatedPipeRollingMachines 1.Introduction Automatedpiperollingmachinesarewidelyusedinvariousindustriesformassproductionofpipeswithconsistentwallthickness.Thecontrolofwallthicknessduringtherollingprocessiscrucialtoensurethequalityandperformanceofthepipes.Thispaperexploresthedifferentmethodsemployedinautomatedpiperollingmachinestocontrolthewallthicknessofpipes. 2.Background Thewallthicknessofapipeisacriticalparameterthataffectsitsstrength,durability,andfunctionality.Inautomatedpiperollingmachines,controllingthewallthicknessduringtherollingprocessisessentialtomeetthespecifiedrequirements.Theprimaryobjectiveofthesemachinesistoproducepipeswithauniformwallthicknessthroughouttheirlength. 3.MethodsofWallThicknessControl 3.1.RollGapControl Oneofthemostcommonmethodsusedinautomatedpiperollingmachinesisrollgapcontrol.Rollgapreferstothedistancebetweentherolls,whichdeterminesthefinaldimensionsofthepipe.Byadjustingtherollgap,theoperatorcancontrolthewallthicknessofthepipe.Thismethodiseffectiveinachievingconsistentwallthickness,especiallyforpipeswithauniformcross-section. 3.2.YieldStrengthControl Insomecases,thewallthicknesscontrolisachievedbyadjustingtheyieldstrengthofthematerial.Byalteringthematerialcompositionortemperature,theyieldstrengthofthematerialcanbemodified.This,inturn,affectsthedeformationbehaviorduringtherollingprocess,leadingtocontrolledwallthickness.However,thismethodrequirescarefulmaterialselectionandtestingtoensurethedesiredresults. 3.3.FeedRateControl Controllingthefeedrateofthepipematerialintotherollingmachineisanotherapproachtoachievingwallthicknesscontrol.Byadjustingthespeedatwhichthematerialisfed,theamountofmaterialthatenterstherollscanbecontrolled,therebycontrollingthewallthickness.Thismethodisparticularlyusefulforpipeswithvaryingcross-sections. 3.4.RollDesignOptimization Thedesignoftherollsalsoplaysacrucialroleinwallthicknesscontrol.Byoptimizingtherolldesign,itispossibletoachievebettercontroloverthewallthic
