J.T.S法对改善二辊楔横轧轧件心部质量的研究
Title:AStudyontheApplicationofJ.T.SMethodtoImprovetheInternalQualityofTwo-rollWedgeCross-rollingRollingStock
Abstract:
Inrecentyears,thedemandforhigh-qualityrollingstockhasbeenincreasing,bothintermsofperformanceandinternalquality.Thetwo-rollwedgecross-rollingprocessisanimportantmethodforproducingseamlesspipeproducts.However,defectssuchascracksandinternalvoidsarepronetooccurduringthemanufacturingprocess,leadingtoadeclineinthequalityofthefinalproduct.ThisstudyaimstoexploretheapplicationoftheJ.T.Smethodtoenhancetheinternalqualityoftwo-rollwedgecross-rollingrollingstock.

1.Introduction
Thetwo-rollwedgecross-rollingprocessiswidelyusedtoproduceseamlesspipesduetoitsadvantagesofhighproductivity,lowcost,andgoodmechanicalproperties.However,theinternalqualityoftherollingstockcanbecompromisedduetotheoccurrenceofdefectssuchascracks,internalvoids,andnon-uniformmicrostructures.Thesedefectsnotonlyaffecttheoverallperformanceoftheproductbutalsoposesafetyconcernsincriticalapplicationssuchaspressurevesselsandpipelines.
2.J.T.SMethod-PrincipleandMechanism
J.T.S,whichstandsforJetTargetSpraying,isamethodproveneffectiveinimprovingtheinternalqualityofrolledproducts.Itisbasedontheprincipleofcontrollingthecoolingrateandcontrollingthemicrostructureformationduringtherollingprocess.Byemployingwaterspraycoolingatspecificintervals,theJ.T.Smethodcansignificantlyreducetheoccurrenceofdefectsandenhancetheinternalqualityoftherollingstock.
3.ExperimentalProcedure
ToinvestigatetheeffectivenessoftheJ.T.Smethod,aseriesofexperimentswereconducted.Sampleswerepreparedusingthetwo-rollwedgecross-rollingprocessunderdifferentcoolingconditions:withoutJ.T.Streatment,withintermittentJ.T.Streatmentatspecificintervals,andcontinuousJ.T.Ssprayingduringtheentirerollingprocess.Theinternalqualityandmechanicalpropertiesofthesampleswereanalyzedusingtechniquessuchasnon-destructivetesting,metallographicexamination,andmechanicalt
