Keywords:twin-rollcastingprocess,high-speedsteelstrips,microstructure,post-treatment 1.Introduction Thetwin-rollcastingprocessisacontinuouscastingtechnologythatusesapairofparallelrotatingrollstocastliquidsteelintoflatstrips.Duringthecastingprocess,thesteelstripsundergorapidsolidification,resultinginafineanduniformmicrostructure.Thetwin-rollcastingprocessiswidelyusedintheproductionofhigh-strengthandhigh-performancesteelstrips,aswellasinthecastingofnon-ferrousmetalsandalloys. High-speedsteelisatypicalcuttingtoolmaterialthathashighhardness,highwearresistance,andexcellentprocessingperformance.Thetwin-rollcastingprocesscanproducehigh-speedsteelstripswithexcellentmicrostructureandmechanicalproperties,whichcansignificantlyreducetheproductioncostofhigh-speedsteelproducts.However,themicrostructureandmechanicalpropertiesofhigh-speedsteelstripsdependonvariousfactors,suchasthecastingtemperature,castingspeed,andcoolingrate.
