T4, T5, thiab T6 ntawm 6000 series txhuas khoom yog dab tsi?
Ob qho tib si architectural thiab industrial aluminium profiles yog tsim los ntawm 6000 series, uas yog aluminium magnesium silicon alloy. Lub 6063 txhuas profile muaj qhov zoo heev formability, muaj zog corrosion kuj, thiab weldability. Tom qab kev laus, lub hardness tuaj yeem ua tau raws li qhov yuav tsum tau siv. Yog li 6063 aluminium profile nrov heev.
Muaj peb lub xeev ntawm 6063 txhuas profiles: T4, T5, thiab T6. Lub xeev T4 muaj qhov nyuaj tshaj plaws, thaum lub xeev T6 muaj qhov nyuaj tshaj plaws.
T txhais tau tias kev kho mob, thiab cov nram qab no 4, 5, 6 sawv cev rau txoj kev kho cua sov. Hauv cov ntsiab lus kev tshaj lij,
T4 lub xeev yog cov khoom siv kho mob ntxiv rau kev laus laus;
T5 lub xeev yog cov khoom siv kho mob ntxiv rau kev laus tsis tiav;
T6 lub xeev yog cov khoom siv kho mob ntxiv rau kev ua kom tiav kev laus.
Qhov txawv ntawm T4, T5, thiab T6 yog dab tsi?
Lub xeev 6063-T4 yog tias cov txhuas profile yog extruded los ntawm extruder thiab txias, tab sis tsis muab tso rau hauv lub cub tawg rau kev laus. Aluminium profiles uas tsis dhau kev laus muaj qis hardness thiab zoo deformability, ua rau lawv haum rau tom qab deformation ua xws li khoov.
6063-T5 yog peb hom uas tsim tawm ntau tshaj plaws, uas yog extruded, cua txias, quenched, thiab tom qab ntawd hloov mus rau hauv lub qhov cub laus rau li 200 degrees Celsius rau 2-3 teev. Lub xeev ntawm aluminium profile tom qab tsim tuaj yeem ncav cuag T5. Aluminium profiles nyob rau hauv lub xeev no muaj kuj hardness thiab tej yam deformability.Yog li feem ntau lub tsev aluminium profiles thiab industrial aluminium profiles nyob rau hauv lub xeev no.
Lub 6063-T6 lub xeev yog quenched los ntawm dej txias, thiab cov khoom siv hluav taws xob kub tom qab quenching yuav siab dua, thiab lub sij hawm tuav yuav ntev dua kom ua tiav lub xeev hardness dua.
Lub T5 lub xeev txhuas profile tau txais cov khoom siv nrog lub zog nruab nrab thiab qee yam yas, thaum lub xeev T6 tau txais cov tawv tawv dua thiab qis dua. Lub xeev T4 ua tiav qhov qis tshaj plaws hardness tab sis siab plasticity.
The different heat treatment methods result in different physical and mechanical strength obtained. The order should be T6>T5>T4, yog li T4 yog tsim rau deformation ua, xws li dabtsi yog khoov. T5 feem ntau yog siv rau lub tsev aluminium profiles thiab muaj txhuas profiles. Yog tias muaj qhov xav tau ntau dua rau kev ua kom tawv tawv, T6 cov ntaub ntawv tuaj yeem siv tau.
Dab tsi ntsuas yog siv los ntsuas qhov hardness ntawm aluminium profiles
Hardness yog ib qho ntawm cov khoom siv feem ntau siv los ntsuas cov khoom siv hluav taws xob ntawm cov hlau, thiab nws cov ntsiab lus yog lub peev xwm ntawm cov hlau nws tus kheej los tiv thaiv lub siab ntawm lwm yam khoom nyuaj dua li nws. Lub hardness ntawm cov hlau sib txawv, thiab qhov sib txawv ntawm cov khoom ntawm aluminium alloys kuj tuaj yeem ua rau qhov sib txawv ntawm hardness.
Ua ntej ntawm tag nrho cov, cia peb qhia cov hlau hardness testers. Cov uas nquag siv hauv ntiaj teb no yog Brinell hardness testers, Rockwell hardness testers, Vickers hardness testers, Knoop hardness testers, Vickers hardness testers, thiab Babbitt hardness testers. Cov hardness testers ntsuas hlau hardness statically. Txhua txoj kev ntsuas hardness muaj nws tus kheej zoo. Txoj kev siv feem ntau los ntsuas kev lag luam aluminium profiles yog Vickers hardness tester.
Vickers hardness tester yog me me, hnyav, thiab tuaj yeem ua haujlwm nrog ib txhais tes. Nws tuaj yeem ntsuas qhov tawv tawv txhua lub sijhawm thiab nyob qhov twg thaum lub sijhawm tsim cov khoom lag luam aluminium profiles. Kev ntsuas lub hauv paus ntsiab lus ntawm Webster hardness tester yog siv qee yam ntawm cov tawv steel siab rab koob los nias rau hauv qhov chaw ntawm aluminium profiles nyob rau hauv qhov kev txiav txim ntawm tus qauv caij nplooj ntoos hlav test force, thiab txiav txim siab hardness ntawm txhuas profiles raws li qhov tob ntawm lub siab. koob nias. Ntxiv mus, muaj aluminium profiles yog cov khoom siv nrog ob lub ntsej muag sib luag, ua rau lawv tsim nyog rau kev ntsuas nrog Vickers hardness tester.
Muaj aluminium profiles yog tsim nyob rau hauv ntau thiab yuav tsum tau soj ntsuam hauv paus. Lub compact thiab saj zawg zog Vickers hardness tester yog heev haum rau hom no ntau lawm site.
