Ntxiv rau kev ua kom ntseeg tau tias muaj cov tshuaj lom neeg thiab cov khoom siv kho tshuab, kev ntsuam xyuas hydrostatic raug ua ib qho los ntawm ib qho, thiab kev ntsuam xyuas flaring thiab flattening raug ua. . Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, qhov loj me ntawm cov noob, thiab txheej decarburization ntawm cov yeeb nkab hlau tiav.
Kev Ntsuas Tensile:
1. Rau cov khoom siv hlau, cov chaw tsim khoom yuav tsum ua qhov kev sim tensile. Rau cov yeeb nkab hluav taws xob welded, nyob ntawm seb cov chaw tsim khoom xaiv, kev sim tensile tuaj yeem ua rau ntawm cov hlau phaj uas siv los ua yeeb nkab lossis perfomred ncaj qha rau ntawm cov yeeb nkab hlau. Kev sim ua rau cov khoom kuj tseem siv tau ua qhov kev sim khoom.
2. Cov raj kuaj yuav tsum raug xaiv yam tsis xaiv. Thaum xav tau ntau qhov kev kuaj, txoj kev kuaj yuav tsum xyuas kom meej tias cov qauv uas tau coj los sawv cev rau qhov pib thiab qhov kawg ntawm lub voj voog kho cua sov (yog tias siv tau) thiab ob qho kawg ntawm lub raj. Thaum xav tau ntau qhov kev kuaj, tus qauv yuav tsum tau coj los ntawm ntau lub raj sib txawv tsuas yog tias cov qauv raj tuab tuaj yeem coj los ntawm ob qho kawg ntawm lub raj.
3. Cov qauv yeeb nkab tsis sib txuas tuaj yeem coj mus rau txhua qhov chaw ntawm qhov ncig ntawm cov yeeb nkab; cov qauv yeeb nkab vuam yuav tsum tau coj mus rau ntawm kwv yees li 90 ° rau ntawm qhov vuam seam, lossis ntawm qhov kev xaiv ntawm tus neeg tsim khoom. Cov qauv raug coj mus rau ntawm kwv yees li ib feem plaub ntawm qhov dav ntawm daim kab xev.
4. Txawm ua ntej thiab tom qab qhov kev sim, yog tias pom tias qhov kev npaj qauv tsis zoo lossis tsis muaj cov ntaub ntawv tsis muaj feem cuam tshuam rau lub hom phiaj ntawm qhov kev sim, cov qauv yuav raug pov tseg thiab hloov nrog lwm cov qauv ua los ntawm tib lub raj.
5. Yog tias qhov kev sim tensile uas sawv cev rau ib pawg khoom tsis ua tau raws li qhov yuav tsum tau ua, tus neeg tsim khoom tuaj yeem coj lwm 3 lub raj los ntawm tib pawg raj rau kev tshuaj xyuas dua.
Yog tias tag nrho cov kev kuaj dua ntawm cov qauv ua tau raws li qhov yuav tsum tau ua, cov pawg ntawm cov raj tau tsim nyog tshwj tsis yog cov raj tsis tsim nyog uas tau kuaj thawj zaug.
Yog tias muaj ntau tshaj ib qho qauv kuaj thawj zaug lossis ib lossis ntau qhov qauv kuaj rov qab tsis ua raws li qhov yuav tsum tau ua, tus neeg tsim khoom tuaj yeem tshuaj xyuas cov raj ib qho zuj zus.
Cov khoom uas raug tsis lees txais tuaj yeem rov ua kom sov thiab rov ua dua tshiab.
Kev Ntsuas Flattening:
1. Cov qauv kuaj yuav tsum yog lub nplhaib kuaj lossis qhov kawg txiav tsis tsawg dua 63.5 hli (2-1 / 2in).
2. Cov qauv yuav raug txiav ua ntej kho cua sov, tab sis yuav tsum tau kho cua sov tib yam li cov yeeb nkab uas sawv cev. Yog tias siv kev sim ua pawg, yuav tsum muaj kev ntsuas los txheeb xyuas qhov kev sib raug zoo ntawm cov qauv thiab lub raj kuaj. Txhua lub cub tawg hauv txhua pawg yuav tsum raug tsoo.
3. Cov qauv yuav tsum tau tiaj tiaj ntawm ob lub phaj sib luag. Hauv txhua pawg ntawm cov qauv sim tiaj tiaj, ib qho vuam tau tiaj tiaj ntawm 90 ° thiab lwm qhov tiaj tiaj ntawm 0 °. Cov qauv yuav tsum tau tiaj tiaj kom txog thaum cov phab ntsa raj sib cuag. Ua ntej qhov deb ntawm cov phaj sib luag tsawg dua tus nqi teev tseg, yuav tsum tsis muaj kab nrib pleb lossis tawg tshwm sim hauv ib feem ntawm tus qauv. Thaum lub sijhawm tag nrho cov txheej txheem tiaj tiaj, yuav tsum tsis muaj cov qauv tsis zoo, cov vuam tsis sib xyaw, delamination, hlau overburning, lossis hlau extrusion.
4. Txawm ua ntej thiab tom qab qhov kev sim, yog tias pom tias qhov kev npaj qauv tsis zoo lossis tsis muaj cov ntaub ntawv tsis muaj feem cuam tshuam rau lub hom phiaj ntawm qhov kev sim, cov qauv yuav raug pov tseg thiab hloov nrog lwm cov qauv ua los ntawm tib lub raj.
5. Yog tias muaj cov qauv uas sawv cev rau ib lub raj tsis ua raws li cov kev cai tshwj xeeb, tus neeg tsim khoom tuaj yeem coj ib qho qauv los ntawm tib qhov kawg ntawm lub raj rau kev kuaj ntxiv kom txog thaum ua tiav cov kev cai. Txawm li cas los xij, qhov ntev ntawm lub raj tiav tom qab kuaj yuav tsum tsis pub tsawg dua 80% ntawm qhov ntev thawj. Yog tias muaj cov qauv ntawm lub raj uas sawv cev rau ib pawg khoom tsis ua raws li cov kev cai tshwj xeeb, tus neeg tsim khoom tuaj yeem coj ob lub raj ntxiv los ntawm pawg khoom thiab txiav cov qauv rau kev kuaj dua. Yog tias cov txiaj ntsig ntawm cov kev xeem rov ua dua no txhua yam ua tau raws li cov kev cai, pawg ntawm cov raj tau tsim nyog tshwj tsis yog lub raj uas tau xaiv thawj zaug ua cov qauv. Yog tias muaj cov qauv rov ua dua tsis ua raws li cov kev cai tshwj xeeb, tus neeg tsim khoom tuaj yeem coj cov raj seem ntawm pawg ib qho dhau ib qho. Ntawm qhov kev xaiv ntawm tus neeg tsim khoom, txhua pawg ntawm cov raj tuaj yeem rov ua kom sov thiab rov kuaj dua ua pawg ntawm cov raj tshiab.
Kev Ntsuas Kev Cuam Tshuam:
1. Rau cov raj, yuav tsum tau muab ib pawg qauv los ntawm txhua pawg (tshwj tsis yog tias cov txheej txheem sau tseg tau pom tias ua tau raws li cov cai tswjfwm). Yog tias qhov kev txiav txim raug teem rau ntawm A10 (SR16), qhov kev sim yog qhov yuav tsum tau ua.
2. Rau lub casing, 3 lub yeeb nkab hlau yuav tsum tau coj los ntawm txhua pawg rau kev sim. Cov raj kuaj yuav tsum raug xaiv random, thiab txoj kev kuaj yuav tsum xyuas kom meej tias cov qauv muab tuaj yeem sawv cev rau qhov pib thiab qhov kawg ntawm lub voj voog kho cua sov thiab sab pem hauv ntej thiab sab nraub qaum ntawm lub tes tsho thaum lub sijhawm kho cua sov.
3. Kev sim cuam tshuam Charpy V-notch
4. Txawm ua ntej thiab tom qab qhov kev sim, yog tias pom tias cov qauv npaj tsis zoo lossis tsis muaj cov ntaub ntawv tsis muaj feem cuam tshuam rau lub hom phiaj ntawm qhov kev sim, cov qauv yuav raug pov tseg thiab hloov nrog lwm cov qauv ua los ntawm tib lub raj. Cov qauv yuav tsum tsis txhob raug txiav txim siab tias tsis zoo tsuas yog vim lawv tsis ua tau raws li qhov yuav tsum tau muaj zog tsawg kawg nkaus.
5. Yog tias qhov tshwm sim ntawm ntau tshaj ib qho qauv qis dua qhov yuav tsum tau muaj zog tsawg kawg nkaus uas nqus tau, lossis qhov tshwm sim ntawm ib qho qauv qis dua 2/3 ntawm qhov yuav tsum tau muaj zog tsawg kawg nkaus uas nqus tau, yuav tsum muab peb qho qauv ntxiv los ntawm tib daim thiab rov kuaj dua. Lub zog cuam tshuam ntawm txhua qhov qauv uas rov kuaj dua yuav tsum ntau dua lossis sib npaug rau qhov yuav tsum tau muaj zog tsawg kawg nkaus uas nqus tau.
6. Yog tias cov txiaj ntsig ntawm ib qho kev sim tsis ua raws li qhov yuav tsum tau ua thiab cov xwm txheej rau qhov kev sim tshiab tsis ua raws li, ces yuav muab peb daim qauv ntxiv los ntawm txhua daim ntawm peb daim ntawm pawg. Yog tias tag nrho cov xwm txheej ntxiv ua tau raws li qhov yuav tsum tau ua, pawg ntawd tau tsim nyog tshwj tsis yog qhov uas tsis ua tiav thaum xub thawj. Yog tias muaj ntau dua ib daim ntxiv uas tsis ua raws li qhov yuav tsum tau ua, tus neeg tsim khoom tuaj yeem xaiv los tshuaj xyuas cov seem ntawm pawg ib qho zuj zus, lossis rov ua kom sov pawg thiab tshuaj xyuas nws hauv pawg tshiab.
7. Yog tias ntau tshaj ib qho ntawm peb yam khoom uas yuav tsum tau ua pov thawj tias ib pawg ntawm cov raj tau tsim nyog raug tsis lees txais, kev rov kuaj xyuas dua tsis raug tso cai los ua pov thawj tias pawg ntawm cov raj tau tsim nyog. Lub chaw tsim khoom tuaj yeem xaiv los kuaj xyuas cov pawg seem ib daim zuj zus, lossis rov ua kom sov dua thiab kuaj xyuas nws hauv pawg tshiab.
Kev Ntsuas Hydrostatic:
1. Txhua lub yeeb nkab yuav tsum raug kuaj xyuas qhov siab hydrostatic ntawm tag nrho cov yeeb nkab tom qab ua kom tuab (yog tias tsim nyog) thiab kho cua sov kawg (yog tias tsim nyog), thiab yuav tsum mus txog qhov siab hydrostatic uas tau teev tseg yam tsis muaj qhov xau. Lub sijhawm tuav qhov siab sim tau ua tsawg dua 5 vib nas this. Rau cov yeeb nkab vuam, qhov vuam ntawm cov yeeb nkab yuav tsum tau kuaj xyuas seb puas muaj qhov xau nyob rau hauv qhov siab sim. Tshwj tsis yog tias qhov kev sim tag nrho cov yeeb nkab tau ua tiav tsawg kawg ua ntej ntawm qhov siab xav tau rau qhov kawg ntawm cov yeeb nkab, lub Hoobkas ua xov yuav tsum ua qhov kev sim hydrostatic (lossis npaj qhov kev sim zoo li no) ntawm tag nrho cov yeeb nkab.
2. Cov kav dej uas yuav tsum tau kho cua sov yuav tsum raug kuaj hydrostatic tom qab kev kho cua sov zaum kawg. Lub siab sim ntawm txhua cov kav dej uas muaj cov xov yuav tsum tsawg kawg yog lub siab sim ntawm cov xov thiab cov txuas.
3. Tom qab ua tiav qhov loj ntawm cov yeeb nkab tiaj tiaj thiab txhua qhov sib txuas luv luv uas tau kho cua sov, qhov kev sim hydrostatic yuav tsum tau ua tom qab qhov kawg tiaj tiaj lossis cov xov.
