Tam sim no cov xwm txheej ntawm txhuas alloy cov ntawv rau tsheb lub cev
Aluminium alloy cov ntawv txheeb uas tuaj yeem siv rau lub cev tsheb feem ntau suav nrog 2000 series, 5000 series, 5000 series thiab 6000 series alloys. Cov kev tshawb fawb ntawm aluminium alloys rau cov ntawv txheeb lub cev yog qhia los ntawm ob lub cev, kev siv cua sov ntawm txhuas alloy rau lub cev tsheb.
Txhuas alloys tau siv nyob rau hauv cov tsheb feem ntau suav nrog kev tuag castings, zam txim, extrusions thiab cov nplooj ntawv. Ntawm no cov khoom lag luam, deformed txhuas alloy cov ntawv siv siv rau stamping muaj cov kev xav tau siab tshaj plaws ntawm aluminium alloy. Deformed txhuas alloy cov ntawv muaj peev xwm txo qhov hnyav ntawm cov tsheb thaum hloov cov hlau tsoos. Piv txwv li, piv nrog cov steel seem, qhov hnyav ntawm txhuas alloy cav npog tuaj yeem raug txo los ntawm ntau dua 40%. Nyob rau tib lub sijhawm, vim qhov zoo thermal conductivity ntawm txhuas alloy, qhov kub ntawm lub cav tuaj yeem txo qis. Ib qho ntxiv, cov khoom tshwj xeeb ntawm txhuas alloy tuaj yeem txo cov kev puas tsuaj rau cov neeg taug kev thaum sib tsoo, uas yog qhov ua kom muaj kev sib tsoo ntawm cov neeg taug kev kev tiv thaiv. Tam sim no, cov ntawv txheeb aluminium aluminium siv rau cov thawv tsheb feem ntau suav nrog 5000 series thiab 616, 6016, 6016, 6016, 6016, 6016, 6016, 6016, 6016, 6016, 6016, 516, 6016, 516, 6016, 6016, 6016, 5182, thiab 6181. Cov kev xav tau kev ua tau zoo ntawm aluminium alloys rau cov tsheb npog tsheb tsis tshua muaj siab, yog qhov txuas tseem ceeb yuav tsum tau tswj hwm thaum lub sijhawm cov txheej txheem ntau lawm. Nyob rau hauv cov khoom siv raw ntau lawm theem, cov ntaub ntawv yuav tsum tau tsim, smelted thiab nrum. Tom qab homogenization kev kho cua sov, cov ntaub ntawv tau npaj rau hauv cov ntawv txheeb ntawm cov txheej txheem tuab thiab kub dov cov txheej txheem. Thaum kawg, lub koom haum thiab theem ob yog tswj los ntawm kev kho cua sov kom ua tiav cov khoom uas xav tau ntau lawm. Hauv tag nrho cov txheej txheem ntau lawm, tsim nyog tsim qauv thiab cov txheej txheem kev kho cua sov yog qhov tsim nyog ua ntej los xyuas cov ntawv zoo. Txawm li cas los xij, piv nrog cov khoom me me, aluminium alloy cov ntawv qhia tseem muaj qhov tsis zoo nyob hauv cov txheej txheem tsim, xws li rov ua dua tshiab thiab tawg yooj yim. Cov kev tsis zoo no yuav tsum tau ua kom zoo thiab raug them nyiaj rau pwm thiab cov txheej txheem. Yog li ntawd, txhawm rau daws cov teeb meem ntawm kev tawg thiab rov qab, cov qauv kev tshawb fawb feem ntau yog siv los ua kev tshawb fawb ntawm kev sib sau ua ke ntawm kev tsim cov thev naus laus zis lossis txheej txheem.
Ntxiv cov kab tseem ua rau alloys alloys tuaj yeem txhim kho lawv cov khoom siv neeg kho mob ua haujlwm. Piv txwv li, ntxiv lub ntiaj teb tsis tshua muaj zog rau aluminium alloys tuaj yeem txhim kho thiab ua kom tsis txhob muaj cov txheej txheem aluminium, thiab tshem tawm cov neeg siv cov khoom siv ntawm aluminium alloys, thiab tshem tawm cov khoom siv cais thiab tshem tawm cov impurities nyob rau hauv alloy. Tom qab qee cov txheej txheem kho cua sov, lub phaj txhuas phaj tuaj yeem txhim kho nws cov qauv thiab cov kws kho mob thiab muaj cov formability zoo dua.
