3003 H18 txhuas muaj peev xwm tsim tau tsawg heev vim nws txoj kev mob siab heev - mob hnyav. Nws cov hardness siab thiab tsis tshua muaj ductility ua rau nws tsis tshua muaj siab tawg thaum khoov, stamping, thiab sib sib zog nqus nqus cov haujlwm. Nws feem ntau tsis pom zoo rau kev tsim. Rau kev tsim cov txheej txheem uas yuav tsum tau deformation, softer tempers xws li 3003 O los yog 3003 H14 yog nruj me ntsis nyiam.
Thaum muas aluminium rau kev khiav haujlwm tshiab, ib qho yuam kev ua los ntawm pawg neeg yuav khoom yog xaiv cov khoom siv nrog lub zog tensile siab tshaj plaws, piv txwv tias nws yuav ua rau cov khoom siv ruaj khov kawg. Rau 3003 alloy, qhov kev xaiv yog H18 temper. Txawm li cas los xij, thaum cov nplooj ntawv 3003 H18 tuaj txog ntawm lub Hoobkas thiab ntaus cov xovxwm nres lossis xovxwm stamping, cov khoom tawg, ua rau cov khoom seem loj heev.
Cov lus qhia dav dav no piav qhia qhov tseeb metallurgical vim li cas tom qab tsim cov kev txwv ntawm 3003 H18 txhuas, tshuaj xyuas cov kev ua haujlwm tsis zoo ntawm lub Hoobkas hauv pem teb, muab piv nrog cov txheej txheem tsim, thiab muab cov lus qhia ua tau zoo rau kev kho koj cov khoom tshwj xeeb kom tshem tawm kev tawg.
3003 H18 Aluminium Sheet yog dab tsi?
3003 aluminium alloy belongs rau 3xxx series, qhia tias nws yog alloyed feem ntau nrog manganese (Al-Mn). Nws tau txais txiaj ntsig zoo rau nws qhov zoo heev corrosion kuj. Critically, 3003 yog ib qho uas tsis yog - tshav kub- kho tau alloy. Nws lub zog txhua yam tsis tuaj yeem siv tau los ntawm kev siv lub tshuab hluav taws xob laus; nws yuav tsum muaj zog mechanically.
H18 lub npe hu ua nruj me ntsis rau nws lub cev npau taws. Nws qhia tias "tag nrho- nyuaj" xeev. Ntawm lub tshuab dov, cov txhuas yog txias- dov nyob rau hauv chav tsev kub rau nws qhov siab tshaj plaws kev lag luam txo thickness. Tsis muaj thermal annealing yog siv rau soften nws. Cov txheej txheem no thawb lub zog tawm los thiab qhov tawv tawv ntawm 3003 alloy rau nws lub cev qhov siab tshaj plaws.
Core Mechanism Qab 3003 H18 Tsim Cov Kev Txwv
Vim li cas lub zog siab sib npaug sib npaug tsis zoo? Cov lus teb yog nyob rau hauv microscopic grain qauv ntawm cov hlau.
Thaum lub caij txias txias- dov txheej txheem siv los tsim H18 temper, cov khoom siv lead ua sab hauv ntawm aluminium yog deformed heev, flattened, thiab compressed. Qhov kev siv tshuab ua haujlwm no ua rau muaj kev nce ntxiv hauv "dislocation ntom" hauv cov iav siv lead ua.
Dislocations yog microscopic defects hauv cov qauv siv lead ua. Raws li cov hlau txias- dov, cov dislocations ntau thiab entangle nrog ib leeg. Vim tias lawv tau ntim nruj heev thiab tangled, cov pob zeb siv lead ua poob lawv lub peev xwm los swb dhau ib leeg.
Thaum koj sim ua los yog khoov ib lub hlau, cov nplej yuav tsum tau swb thiab ncab. Vim tias cov nplej hauv 3003 H18 raug kaw tag nrho los ntawm qhov sib txawv ntawm qhov siab, cov khoom siv yuav luag xoom plasticity (ductility). Es tsis txhob ncab kom haum rau qhov khoov, qhov nro sab hauv kov yeej cov qauv kev ncaj ncees, thiab cov kua muag hlau. Lub zog nyob rau hauv no npau taws yog tiav tag nrho ntawm kev txi ntawm formability.
Thawj Txoj Kev Txwv ntawm 3003 H18 Aluminium Phaj
Qhov tsis muaj ductility no txhais tau ncaj qha mus rau hauv kev txwv hnyav rau hauv pem teb kev tsim khoom thoob plaws txhua qhov kev qhuab qhia loj.
Bending txwv
3003 H18 yog qhov tsis tsim nyog rau tus qauv xovxwm nres dabtsi yog khoov. Nws yuav tsum muaj qhov tshwj xeeb loj qhov qis qis qis, feem ntau 4 mus rau 6 npaug ntawm cov khoom tuab (4T - 6T). Sim ua kom ntse 90-degree khoov yuav ua rau cov fibers sab nraud ntawm cov khoom siv tam sim ntawd.
Stamping txwv
Thaum nws tuaj yeem ua haujlwm siab - nrawm nrawm nrawm (txhaj cov duab tiaj tus tawm ntawm daim ntawv), nws tsis tuaj yeem ua haujlwm stamping uas xav kom cov hlau ncav mus rau hauv qhov tuag. Cov khoom yuav sai sai tsim micro- tawg lossis tawg tag ntawm cov ntsiab lus ntawm kev ntxhov siab ntau tshaj.
Kev txwv kev kos duab sib sib zog nqus
Daim duab sib sib zog nqus yog tsis yooj yim sua nrog 3003 H18. Cov txheej txheem yuav tsum tau elongation loj heev kom rub daim ntawv tiaj tus mus rau hauv ib lub cylindrical sib sib zog nqus los yog lub thawv -zoo li tus tuag. 3003 H18 yuav ua tsis tiav thiab tsim kua muag thaum pib ntawm kev kos duab.
Hom Failure Hom hauv Sheet Hlau Fabrication
Yog tias cov chaw tsim khoom sim yuam 3003 H18 los ntawm kev tsim cov txheej txheem, ntau hom kev ua tsis tiav yuav tshwm sim.
| Hom kev ua tsis tiav | Pom qhov tshwm sim | Engineering Ua |
| Nto Cracking | Pom pom kev sib cais ntawm lub vojvoog sab nraud ntawm qhov khoov. | Cov hlau sab nrauv fiber ntau tshaj lawv qhov siab tshaj plaws elongation (uas tsuas yog 1-4% rau H18) thiab tsim kua muag hauv qhov nro. |
| Ntug Cracking | Cov kua muag pib los ntawm cov npoo txiav thaum lub sij hawm stamping. | Kev ntxhov siab ua kom pom tseeb ntawm microscopic burrs sab laug los ntawm shearing, thiab cov khoom tawg tsis tuaj yeem faib cov khoom thauj. |
| Severe Springback | Cov hlau unbends tseem ceeb tom qab cov xovxwm tso tawm. | Qhov tsis tshua muaj zog tawm los ua rau cov khoom siv los tua cov deformation, ua kom lub kaum ntse ntse tswj yuav luag tsis yooj yim sua. |
| Ua kom tawg | Ib feem snaps rau hauv ob daim ntawm txoj kab khoov. | Tag nrho tsis ua hauj lwm ntawm cov siv lead ua lattice nyob rau hauv lub zos kev nyuaj siab. |
Puas yog koj tab tom ntsib cov khoom seem siab vim yog ntug tearing, tawg, lossis tsis tuaj yeem tswj tau lub caij nplooj ntoo hlav ntawm koj cov xovxwm? Tsis txhob nkim nyiaj kho cov cuab yeej rau lub siab tsis ncaj ncees lawm. Hu rau peb pab neeg ua haujlwm niaj hnub no kom thov cov qauv kuaj dawb ntawm formable 3003 H14 thiab 3003 O txhuas. Ntsuam xyuas cov khoom ntawm koj tus kheej lub tshuab thiab daws koj cov teeb meem tsim tam sim ntawd.
Cov ntsiab lus tseem ceeb cuam tshuam rau 3003 Aluminium Formability
Txawm tias thaum ua haujlwm nrog cov kev txwv tsis pub tshaj ntawm H18, qee yam tseem ceeb ua rau muaj kev pheej hmoo ntawm kev tawg.
| Qhov xwm txheej | Qhov cuam tshuam rau kev tsim Risk |
| Khoom Thickness | Thicker daim hlau xav tau cov fibers sab nrauv kom ncab ntxiv nyob ib ncig ntawm qhov khoov. Thicker 3003 H18 feem ntau yuav tawg dua li cov ntawv nyias nyias. |
| Khoov Radius | Ib lub vojvoog nruj tsom kev ntxhov siab rau hauv ib qho nqaim. Lub vojvoog loj dua faib cov kev ntxhov siab, me ntsis txo qhov kev pheej hmoo ntawm pob txha. |
| Rolling Direction | Aluminium muaj ib qho kev coj ua. Khoov thaum uas tig mus rau cov nplej (nrog cov nplej) cais cov fibers thiab guarantees cracking. Khoov transverse (dhau ntawm cov nplej) muaj kev nyab xeeb me ntsis. |
| Kub | Kev tsim ntawm chav tsev kub maximizes lub brittleness ntawm H18 temper. |
3003 H18 vs 3003 H14 vs 3003 O Aluminium Chev
Yuav kom daws tau cov kev txwv tsim, koj yuav tsum xaiv qhov tseeb temper. Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv hauv kev tsim nyob rau hauv 3003 alloy tsev neeg.
| Kub | Material State | Elongation (%) | Formability Rating | Daim ntawv thov |
| 3003 O | Annealed tag nrho | > 25% | Zoo heev | Sib sib zog nqus daim duab, heev sib sau, complex spinning. |
| 3003 H14 | Ib nrab -Hard | ~ 5% - 10% | Zoo | General ntawv hlau sib sau, 90-degree dabtsi yog khoov, ntiav stamping. |
| 3003 H18 | Puv -Nruab | ~ 1% - 4% | Neeg pluag heev | Cov vaj huam sib luag tiaj tus, nruj kaw, nruj me ntsis tsis- daim ntawv thov. |
