Tsis zoo siv: Cov kev soj ntsuam siab thiab qis thiab qis dua metallographic kev soj ntsuam tau nqa tawm ntawm cov txiv hmab nrog cov khoom muaj zog hauv zos, thiab cov khoom siv roller yog tau txheeb xyuas. Cov txiaj ntsig tau pom tias qhov muaj nuj nqis qis hauv zos tau tshwm sim los ntawm cov pa roj carbon nyob ntawm cov pa roj carbon nyob ntau dhau ntawm cov khoom siv raw.
Lo lus tseem ceeb: tsawg lub hardness tus nqi; Cov tsheb thauj khoom Freight Tsheb Coj Bwb Cov Ntaub Ntawv; Carbon-pluag
Lub hardness ntawm cov kabmob ntawm cov khoom sib xyaw muaj qhov cuam tshuam loj ntawm lub neej nkees thiab hnav tsis kam, thiab lub hardness tus nqi yog qhov taw qhia tseem ceeb rau kev ntsuas cov kabmob zoo. Yog li ntawd, hauv kev tsim khoom thiab kev ua cov kabmob, muaj cov txheej txheem txhim khu kev ntsuas thiab cov khoom siv raw kom zoo rau cov txheej txheem kev kho cua sov. Tshwj xeeb tshaj yog rau cov tsheb thauj khoom tsheb cov kabmob tom qab kev kho mob TB \/ T2235 uas ua raws cov kabmob tsheb ciav hlau yog {1}} hrc.
Ib pob ntawm GCR15 tus hlau railway freight tsheb nrog tapered rau cov menyuam yaus lub ntsej muag muaj ib sab ntawm lub ntsej muag kawg (saib daim duab 1 rau morphology). Tom qab quenching thiab tempering nyob rau hauv kev kho cua sov cov menyuam cov dej ntxuav ua kom zoo nkauj thiab cov kua txob ntawm muaj cov xim txawv txav ntawm cov menyuam. Lub zog hardness ntawm cov menyuam dov npoo tau pom tias tsawg ntawm 57hrc, 57.5hrc, thiab 57hrc. Tom qab, tus neeg cov menyuam yob cov npoo uas muaj tsawg dua los ntawm lwm cov pob tw, thiab cov kua qaub ntxuav tawm piv yog 1\/50. Txhawm rau kom muaj cov khoom lag luam zoo ntawm cov chais, ua rau cov hauv paus pom kev tshawb xyuas tau ua rau lawv cov qauv thiab kev tshawb fawb tau nqa tawm ntawm cov txheej txheem ua tiav.
Daim duab 1 Cov Khoom Siv Rhais
1. Kev tshuaj xyuas cov qauv tsis xws luag
(1) kev kuaj xyuas hardness ntawm cov qauv tsis xws luag
Siv hra -150 rockwell hardness tester, lub hardness ntawm cov kab ke ntawm cov kab tsuag tau yog 61hrc, 61hrc; 61.5hrc; Lub ntsej muag tawv ntawm cov ntsej muag seem yog 61hrc, 61.5hrc, thiab 62hrc, uas tau raws li cov cai ntawm TB \/ T2235 txheem. Siv V-puab cov plaub ntug, lub hardness ntawm lub rolling saum npoo nrog cov xim zoo li qub tau pom tias yog 61hrc, 61.5hrc, thiab 62hrc. Nws yog pov thawj tias cov qauv tsis xws muaj qhov chaw nyob hauv zos qis ntawm cov qaws dov.
(2) metallographic kev soj ntsuam ntawm thaj chaw uas muaj xim tsis zoo
Grind Metallographic cov qauv qhia raws cov kev taw qhia axial ze ntawm thaj chaw ntawm cov xim tsis muaj xim. Tom qab etching nrog 4% nitric acid dej cawv, daim hlau metallographic qauv ntawm thaj chaw corroded tob tau raug pom ntawm qis thiab 500 zaug magnification. Piv nrog cov qauv duab hauv Daim Ntawv Ntxiv JB \/ t 7362-2007 "}" pom tias muaj cov kabmob carbon decicicon (saib daim duab 2). Thaum cov ntaub ntawv hlau muaj rhaub thiab insulated, cov pa roj carbon nyob rau lawv cov nplaim yog oxidized, uas ua rau tiav lossis ib feem poob ntawm carbon. Qhov tshwm sim no hu ua Decarburization, thiab cov ntug uas cov pa roj carbon tau ploj yog hu ua txheej txheej decarburization. Thaum tsis muaj ntau cov pa roj carbon thiab tsis muaj qhov pom tseeb ntawm cov txheej txheem decarburization tuaj yeem pom, tab sis cov tawv nqaij dhau los yog txo qis thiab lub hardness yog tsawg, nws yog hu ua cov tshuaj carbon tsis txaus.
Daim duab 2: Qhov tob ntawm cov pa roj carbon depletion hauv chais
Tom qab kev sib sib zog nqus corrosion, lub moalallographic qauv ntawm thaj chaw tau pom tias muaj cov pa roj carbon tsis muaj zog, nrog ib tug tob ntawm 0. 28}}. 28}}. 28}}. 28}}. 28}}. 28}}. 28}}. 28}}. 28mm. Hauv qab Olympus GX51 lub tshuab tsom iav GX51 lub ntsej muag me me, lub ntsej muag me me ntawm cov menyuam tau pom ntawm cov menyuam yaus tau pom ntawm qis thiab siab magiciency pom. Txawm li cas los xij, cov pa roj carbon tsis pom muaj nyob ntawm Chamfer ntawm lub ntsej muag loj kawg ntawm cov menyuam. Kev sib sib zog nqus ntawm 500 zaug tuaj yeem saib lub microstructure ntawm thaj chaw no (saib daim duab ntawm lub chaw nyob rau hauv qhov chaw muaj ib qho loj dua ntawm carbide hais (saib Daim Duab 4). Rau cov pa roj carbon tsis zoo, tom qab cov kab mob corrosion, lub lath zoo li qauv morphology ntawm lub npoo kuj tseem tuaj yeem pom tau 500 zaug.
Daim duab 3: Cov pa roj morphology tsis zoo ntawm ntug ntawm cov menyuam
Daim duab 4: Tsis muaj Carbon Tsis Zoo Morphology ntawm qhov tseem ceeb ntawm cov menyuam
(3) Soj ntsuam cov ntaub so ntswg ntawm cov txee ntawm thaj chaw
Firstly, ib cov qauv me me yog coj mus rau ntawm qhov chaw ntawm cov ntaub nyias nyias lub ntsej muag, thiab metallograph cov piv txwv yog av raws cov ntu ntev. Kev saib cov ntaub so ntswg ntawm lub ntsej muag kawg ntawm qhov qauv nrog lub qhov, tsis muaj cov penbon deficitic pereemenon tau pom nyob rau hauv ob qho siab thiab kev soj ntsuam siab magnification. Saib xyuas microstructure ntawm tsis muaj kab noj hniav ntawm cov menyuam, tsis muaj kev txawv txav tau pom.
Raws li kev txheeb xyuas saum toj no, cov hauv zos qis hardness ntawm cov menyuam yog vim cov carbon tsis muaj zog ntawm cov menyuam.
2. Kev Ntsuam Xyuas ntawm Kev Kho Mob Cua Sov
Cov chais ntawm cov tsheb thauj khoom thauj tsheb bearings yog tsim thiab quenched thiab tempered siv batch tswj. Cov khoom siv cua sov ua kom sov yog cov menyuam hauv qab cub ntsev quenching ntau lawm kab nrog kev tiv thaiv kev tiv thaiv rau quenching thiab tempering ua. Nws tau pom tias cov chais ntawm cov qauv no tau ua tiav siv cov raw cov ntaub ntawv los ntawm ob cov tuam ntxhab, A thiab B, rau ntau qhov sib law liag. Tsuas yog cov chais los ntawm cov chaw tsim tshuaj paus uas muaj peev xwm tiv thaiv cov pa roj carbon, thiab cov feem ua feem tsis yog qhov loj heev; Thaum lub sij hawm tshuaj kuaj xyuas ntawm ntau qhov kev hloov pauv ntawm lwm cov khoom lag luam khoom lag luam, tsis muaj cov chais ua haujlwm tsis zoo tau pom. Tsis muaj cov cuab yeej txawv txav tau pom nyob hauv cov ntaub ntawv cua sov. 100% acid ntxuav thiab xaiv tau nqa tawm ntawm cov chais nrog cov teeb meem tsis zoo. Los ntawm cov chais khaws, nws tuaj yeem pom tau tias lawv kuj yog tus neeg nqa khoom. Yog tias cov pa roj carbon tsis txaus hauv cov txheej txheem kev kho cua sov yog tshwm sim los ntawm cov huab cua tsis zoo, nws yuav tsum yog nyob rau ntawm lub batch. Thaum lub sij hawm acid tshuaj ntxuav tes, qib sib txawv ntawm cov chaw ua kom muaj pa roj carbon thiaj yuav tsum tau pom nyob hauv ib feem ntawm cov menyuam.
Cov Menyuam Cov Menyuam Raug Flow: Cov Khoom Siv Khoom Siv Raw → So Dej Kub → DRINE DRUGRING SECRESS SMECTS. Los ntawm qhov kev pom ntawm tag nrho cov txheej txheem, tsuas muaj ob yam uas ua rau muaj kev txom nyem rau cov pa roj carbon monome: cov khoom siv kub. Raws li kev txheeb xyuas saum toj no, nws yog pom tseeb tias qhov tshwm sim ntawm cov carbon depletion tsis cuam tshuam nrog kev kho cua sov.
3. Raw Khoom Taw Qhia
Tshawb nrhiav cov ntaub ntawv raw ntawm cov pob uas cov menyuam ntawm cov qauv no nyob. Nws yog ib qho tsis Decarburized cov khoom siv tau muab los ntawm qee cov hlua hlau, nrog txoj kab uas hla ntawm 23.2mm, qhov hnyav ntawm 46, thiab tau txais txiaj ntsig tag nrho. Muaj tag nrho ntawm 7 tus lej sub ua kom sov. Txhawm rau kom ntseeg tau qhov zoo ntawm cov chais rau cov khoom siv no, 100% acid ntxuav thiab xaiv tau nqa tawm. Raws li kev ua thiab tag nrho zoo tshuaj xyuas ntawm cov txheej txheem kho cua sov, qhov no yog qhov teeb meem zoo ntsig txog qhov zoo ntawm cov ntaub ntawv raw. Txawm hais tias cov menyuam cov ntaub ntawv raw muaj cov khoom siv tshwj xeeb uas tuaj txog ntawm lub Hoobkas, lawv txhua tus koom nrog tshuaj xyuas cov khoom siv bar. Raws li cov kev xav tau ntawm cov kev txiav txim, cov khoom siv hlau yuav tsum muab cov khoom lag luam Decarburization, tab sis qhov tseeb, lawv tsis tau ntsib cov kev xav tau ntawm cov kabmob kev sib tw. Cov hlau mills yuav tsum muab cov ntaub ntawv tshaj tawm POXTBROZENY. Txawm hais tias lawv kuj tau thim rov qab, tev, thiab polishing, hauv qee qhov kev lom zem, qhov kev txiav txim siab kub tshaj tus qauv lossis teeb meem tswj hwm. Raws li qhov tshwm sim, lub decarburization thiab cov roj carbon txheej rau saum npoo tsis tshem tawm tag nrho, tawm ntawm lawv ntawm cov kabmob chaw tsim tshuaj.
