Hom ncej no muaj kev ua haujlwm zoo.Hauv kev siv tswv yim, nws tsis muaj qhov porosity lossis lwm yam tsis xws luag, yog li nws tsis tsuas yog muaj kev ruaj ntseg zoo, tab sis kuj muaj kev ua tau zoo heev.
Muaj ntau hom iav ncej forgings.Feem ntau siv iav forging cov ntaub ntawv suav nrog 40Cr, 42CrMo, 20CrMnMo, thiab 20CrMnTi.42CrMo thiab 40Cr forged iav yog feem ntau loj iav forgings hauv kev lag luam nqa, thaum 20CrMn molybdenum thiab 20CrMnTi feem ntau yog siv rau forging iav hauv kev sib kis tshuab.Feem ntau cov iav yuav tsum tau nqa cov iav.Hauv 38-42HRC, kev kho cua sov hardness ntawm lub zog ua tiav kev ua haujlwm zoo.Vim qhov zoo tshaj plaws kev kho cua sov hardenability ntawm lub qub, lub toughness ntawm 42CrMo yog zoo dua li ntawm 40Cr, uas yog ze ze rau nws cov khoom.Ib yam li ntawd, ntawm tib lub hardness, lub zog yog ze heev.Lub zog tensile ntawm 40Cr yog 6 ~;Lub zog tensile ntawm 42CrMo yog 110kg / mm2, thiab lub zog tawm los yog 95kg / mm2.Qhov kev ua tau zoo tshaj 40Cr.
40Cr cov khoom muaj zoo hardenability.
Cov dej quenching tuaj yeem ua rau ib txoj kab uas hla ntawm 28-60 millimeters, thaum cov roj quenching tuaj yeem ua rau ib txoj kab uas hla ntawm 15-40 millimeters.Tom qab quenching thiab tempering, cov ntaub ntawv pov thawj zoo heev txhua yam khoom, tsis tshua muaj siab rhiab heev, thiab tsis tshua muaj kub cuam tshuam toughness.40Cr iav forgings yog feem ntau raug rau saum npoo high-frequency quenching los yog nitriding kev kho mob tom qab quenching thiab tempering.Thaum lub hardness yog 174-229HBS, nws muaj zoo machinability, nrog ib tug txheeb ze machinability ntawm 60%.Cov ntsiab lus carbon ntawm 40Cr cov ntaub ntawv forgings yog khaws cia nyob ib ncig ntawm 0.40%, yog li ua kom muaj kev sib xyaw zoo ntawm lub zog thiab tawv ntawm cov hlau.Ntxiv Cr element.(Cr, Fe) 3C.Thawj forging kub ntawm 40Cr iav forgings yog 1100 ~ 1150 ℃, thiab forging kub yog 800 ℃.Tom qab forging, qhov ntev tshaj 60 millimeters yuav tsum tau txias qeeb.
Gear shaft chaw tsim tshuaj paus ceeb toom hais tias cov khoom ntawm iav ncej forgings yuav tsum xub ua raws li cov kev cai ntawm kev ua hauj lwm tej yam kev mob.Thaum xaiv iav forging cov ntaub ntawv, thawj qhov yuav tsum tau xav txog yog cov kev cai ntawm kev ua haujlwm.Alloy steel feem ntau yog siv rau kev tsim cov iav forgings uas ua haujlwm nyob rau hauv high-speed, hnyav-duty, thiab cuam tshuam loads.Kev ntseeg siab yog yuav tsum tau, thiab nws yog ib qho tseem ceeb uas yuav tsum xaiv cov hlau alloy nrog cov khoom siv tshuab siab.Yog hais tias lub iav loj yuav tsum tau me me li sai tau, high-strength alloy steel nrog deg hardening kho yuav tsum tau siv.Cov iav kis tau tus mob hauv cov tshuab mining feem ntau muaj lub zog siab, kev ua haujlwm qis, thiab cov plua plav siab hauv ib puag ncig.Yog li ntawd, cov ntaub ntawv xws li cam khwb cia hlau los yog cam khwb cia hlau yog feem ntau xaiv, tab sis lub suab nrov kis tau tus mob me me, thiab cov zaus ua hauj lwm ntawm lub chaw ua hauj lwm machinery kuj tsawg.Hom ncej no muaj kev ua haujlwm zoo.Hauv kev siv tswv yim, nws tsis muaj qhov porosity lossis lwm yam tsis xws luag, yog li nws tsis tsuas yog muaj kev ruaj ntseg zoo, tab sis kuj muaj kev ua tau zoo heev.
