1, P {-20 Ua ntej Hardened Hlau thiab 45 Carbon Steel: Cov ntaub so mos pwm
Hauv kev txhaj tshuaj pwm, cov ntaub ntawv mos muag tau siv rau kev tsim cov khoom lag luam nrog cov khoom me me thiab tsis yog qhov tseem ceeb rau lub neej muaj pwm. P -20} Ua ntej Hardened hlau thiab 45 carbon steel yog ob qho ntawm cov hom ntau.
P -20 Ua ntej tawv hlau ua ntej
P {-20 Ua ntej tawv hlau ua ntej siv cov hlau sib xyaw Nws muaj cov khoom zoo thiab hnav tsis kam, thiab tuaj yeem tiv taus qee qhov kev sib txhuam thiab kev sib txhuam. P -20} Ua ntej tawv hlau tau siv cov khoom me me, tshwj xeeb hauv kev tsim cov khoom me me, cov khoom siv hluav taws xob me me xws li cov xov tooj thiab lub mloog pob ntseg. Nws qhov tsis zoo yog tias nws lub thermal stability yog ib me ntsis txom nyem thiab nws yog ib qho rau deformation ntawm qhov kub.
45 carbon hlau
45 Pa roj carbon steel yog cov hlau roj carbon steel uas muaj lub zog siab thiab hardness, tab sis kuj tsis muaj zog. Nws yog tsuas yog siv nyob rau hauv kev txhaj tshuaj pwm los tsim cov khoom lag luam nrog cov khoom lag luam tsawg rau lub neej ntawm lub neej. 45 carbon steel muaj tus nqi qis dua thiab ua tau zoo dua qub, tab sis nws yog ib qho yuav ua kom qaug zog ntawm cov pwm kub, uas cuam tshuam rau lub neej ntawm pwm. Yog li ntawd, nyob rau hauv qee cov khoom siv hluav taws xob uas tas lub neej muaj zog, rau ntawm 45 carbon hlau yog qhov tsawg.
2, h {{{1} chromium steel thiab 420 stainless hlau thiab 420 stainless hlau: Cov ntaub ntawv tawv tawv
Cov ntaub ntawv tawv me me yog tsuas yog siv rau kev tsim cov khoom lag luam nrog cov khoom loj thiab qhov kev ua haujlwm siab rau lub neej. H {-13 chromium steel thiab 420 stainless hlau yog ob qho ntawm cov hom ntau.
H -13 chromium steel
H -13 chromium steel yog ib hom kev ua haujlwm kub tuag steel nrog cov khoom siv hluav taws xob zoo heev thiab hnav tsis kam. Nws tuaj yeem tswj lub siab tawv thiab tawv ntawm qhov kub thiab txias, thiab tsis muaj feem rau deformation thiab tawg. H {{1} chromium steel yog dav siv nyob rau hauv kev txhaj tshuaj pwm rau kev tsim cov khoom loj thiab cov teeb meem yog kev ua haujlwm siab thiab tus nqi siab.
420 stainless hlau
420 Stainless hlau yog martensitic stainless hlau nrog lub siab tawv thiab hnav tsis kam, tab sis kuj yog qhov nruj. Nws yog tsuas yog siv los txhaj tshuaj pwm los tsim cov khoom lag luam nrog cov kev xav tau siab rau lub neej ntawm lub neej thiab hnav tsis kam. 420 Stainless hlau muaj zoo corrosion tsis kam thiab tuaj yeem tswj tau ruaj khov ua tau zoo nyob rau hauv qee qhov chaw nruab nrab. Txawm li cas los xij, nws txoj kev ua tau zoo yog neeg pluag thiab yuav tsum tau cov txheej txheem tshwj xeeb thiab cov cuab yeej.
3, cov khoom tshwj xeeb alloy: kev ua haujlwm siab pwm cov khoom
Ntxiv rau cov hlau uas tau hais los saum toj no, tseem muaj qee cov ntaub ntawv tshwj xeeb uas tau siv dav hauv kev txhaj tshuaj pwm. Cov ntaub ntawv no feem ntau muaj hardness siab dua, hnav tsis kam, thiab thermal stability, uas tuaj yeem ua tau raws li cov khoom lag luam uas xav tau ntawm qee cov khoom tshwj xeeb.
Kev Kub Ceev Hlau (HSS)
Cov khoom siv ceev ceev yog ib cov khoom siv alloy nrog lub hardness siab, hnav tsis kam, thiab siab thermal ruaj khov. Nws yog tsuas yog siv los txhaj tshuaj pwm los tsim cov khoom uas muaj qhov yuav tsum tau ua rau pwm lub neej thiab hnav tsis kam. Kev kub ceev cov hlau muaj kev ua tau zoo thiab ua tau zoo, tab sis nws cov nqi yog tus nqi siab, ua kom haum rau qee cov khoom hluav taws xob siab.
Hmoov metallurgy cov ntaub ntawv
Cov khoom me me me yog cov khoom siv alloy ua tau zoo npaj los ntawm cov txheej txheem xim hlau. Nws muaj qhov nyuaj heev, hnav tsis kam, thiab thermal ruaj khov, uas tuaj yeem ua tau kom tau raws li cov khoom lag luam uas xav tau ntawm qee cov khoom tshwj xeeb. Cov khoom me me me yog siv los txhaj tshuaj pwm los tsim cov khoom siv ua kom haum rau lub neej muaj txiaj ntsig zoo nkauj hauv lub xov tooj txawb.
4, cov ntsiab cai thiab kev ceev faj rau cov khoom xaiv
Thaum xaiv txhaj tshuaj pwm, ntau yam uas tau txiav txim siab, kom ntau lawm ntawm cov khoom lag luam, cov khoom siv ntawm lub neej, thiab ib puag ncig kev ua tau zoo. Nov yog qee cov ntsiab cai thiab cov kev ceev faj rau cov khoom xaiv:
Xaiv cov ntaub ntawv raws cov khoom lag luam cov khoom lag luam: Rau cov khoom siv hluav taws xob me me thiab cov khoom siv muag muag xws li p -20} Ua ntej tawv hlau tuaj yeem xaiv; Rau cov khoom loj thiab cov khoom siv hluav taws xob nyuaj, cov khoom siv tawv me me xws li h {1}} chromium steel tuaj yeem xaiv.
Txiav txim siab pwm lifespes: rau cov pwm uas yuav tsum tau xaiv, xws li kev siv hluav taws xob tsis kam, thiab hluav taws xob ceev, thiab lwm yam.
Them sai sai rau cov khoom siv nqi thiab ua kev ua tau zoo: nyob rau hauv lub rooj sib tham cov khoom yuav tsum tau xaiv ntau li ntau tau los txo cov nqi tsim khoom thiab txhim kho ntau dua.
Xav txog kev siv cov kev pab: rau pwm uas yuav tsum tau siv rau hauv cov khoom lag luam kom huv, xws li 420 stainless hlau, yuav tsum tau xaiv.
Them sai sai rau lub thermal stability thiab kev nruj ntawm cov khoom siv: pwm uas ua haujlwm ntawm qhov kub yuav tsum xaiv cov ntaub ntawv nrog siab thermal ruaj khov; Rau cov pwm uas xav tau kev cuam tshuam tseem ceeb quab yuam, cov ntaub ntawv nrog cov tawv nruj yuav tsum tau xaiv.
