Pure aluminum possesses characteristics such as low density, low melting point, and excellent plasticity. Nws qhov ntom yog li ntawm ib -peb ntawm cov hlau, thiab nws lub ntsej muag -centered cubic qauv muab nws zoo formability, ua rau nws yooj yim rau yob rau hauv cov ntawv thiab extrude rau hauv profiles. Nws kuj pom zoo corrosion kuj nyob rau hauv tej yam ntuj tso. Txawm li cas los xij, ntshiab aluminium nws tus kheej muaj lub zog qis, ua rau nws nyuaj rau siv ncaj qha rau hauv cov kev pabcuam aluminium machining. Txhawm rau nthuav dav nws cov ntawv thov, kev lag luam ntxiv dag zog rau nws los ntawm kev ntxiv cov ntsiab lus alloying thiab siv kev kho cua sov, tsim kom muaj cov txheej txheem ntawm aluminium alloys. Thaum tuav nws lub teeb kom zoo dua, aluminium alloys ua tiav lub zog siab, nrog lub zog tshwj xeeb zoo dua rau ntau cov hlau alloy, ua rau lawv cov khoom siv zoo tagnrho rau kev tsim khoom, kev thauj mus los, khoom siv hluav taws xob, thiab aerospace. Aircraft fuselages, tawv nqaij, compressors, thiab lwm yam khoom yog feem ntau ua los ntawm txhuas alloys. Hloov steel vuam nrog aluminium alloys tuaj yeem txo qhov hnyav ntawm cov qauv ntau dua 50%, txhim kho cov cuab yeej ua haujlwm tau zoo.
Nrog txoj kev loj hlob sai ntawm kev lag luam thev naus laus zis thiab kev tsim khoom, qhov kev thov rau aluminium machined qhov chaw tseem loj hlob, tsav lub nruam tob ntawm aluminium alloy ua technology. Kev sib koom ua ke ntawm cov khoom siv thiab kev siv thev naus laus zis tau ua rau aluminium alloy smelting, casting, dov, thiab precision machining cov kev tshawb fawb tseem ceeb hauv kev lag luam, muab qhov chaw txaus rau siab -kawg manufacturing teb xws li txhuas precision machining.
Thawj cov txheej txheem tseem ceeb hauv CNC milling aluminium qhov chaw yog smelting, feem ntau los npaj cov khoom tsim nyog rau kev ua cov yas tom ntej. Gas- raug rho tawm haujlwm lossis roj- cov hluav taws kub nyhiab reverberatory rauv yog feem ntau siv hauv kev tsim khoom, nrog lub peev xwm ntawm 20 txog 40 tons. Cov kab me me kuj tseem siv cov reverberatory furnaces uas muaj peev xwm ntawm kwv yees li 10 tons. Txhawm rau txhim kho melting efficiency thiab txo cov pa roj thiab oxidation inclusions, tilting sab saum toj - nqi hluav taws xob puag yog dav siv. Cov txheej txheem smelting xav tau tiag tiag- lub sij hawm saib xyuas thiab kev hloov kho ntawm qhov muaj pes tsawg leeg siv lub ntsuas ntsuas ceev, thaum lub txheej tiv thaiv yog muab los ntawm cov hmoov flux, feem ntau cov poov tshuaj chloride thiab sodium chloride, ntawm qhov ntau npaum li cas ntawm 0.4% mus rau 2% ntawm lub cub tawg tsub nqi hnyav. Lub smelting kub yog stably tswj ntawm 700-750 degree.
Tom qab melting, lub molten aluminium yuav tsum refining thiab pom kom tshem tawm hydrogen thiab tsis yog -metallic inclusions, txhim kho lub purity ntawm molten aluminium. Refining txoj kev rau txhuas CNC tig yog muab faib ua khoom refining thiab roj refining. Ib txwm siv tshuaj chlorine purification yog siv tau tab sis muaj kuab paug heev; Tam sim no, ib puag ncig tus phooj ywg refining agents xws li nitrogen-chlorine mixes thiab inert gases feem ntau yog siv. Cov pa oxygen thiab noo noo nyob rau hauv cov pa yuav tsum nruj me ntsis tswj hauv qab 0.03% thiab 0.3 g / m³, feem. Lub tshuab nqus tsev dynamic degassing tuaj yeem tshem tawm cov pa roj thiab sodium. Cov txheej txheem lim feem ntau siv cov xov xwm xws li iav mesh, microporous ceramics, thiab alumina hais, thiab tuaj yeem ua ke nrog electrofluids rau kev tshem tawm impurity tob.
Cov txheej txheem casting rau kev cai billet txhuas qhov feem ntau siv cov dej ntsug lossis kab rov tav -cooled semi- nruam casting. Txhawm rau ua kom zoo dua microstructure thiab nto zoo, cov txheej txheem siab heev xws li electromagnetic crystallizers thiab kub-sab saum toj casting tau dhau los ua ntau dua. Dej-cooled semi- nruam nruam siv lub crystallizer kom txias sai thiab shaping; qhov ntsuas kub yog feem ntau 50-110℃saum cov hlau alloy cov kua kab, thiab cov casting thiab txias cov nqi yog maximized. Txij li thaum nws cov kev taw qhia nyob rau hauv nruab nrab-20th caug xyoo, nruam nruam casting thiab dov tshuab rau txhuas ntawv thiab sawb tau dhau los ua ib qho tseem ceeb ntau lawm txoj kev rau nyias nyias thiab txhuas ntawv ci blanks.
Aluminium tig qhov chaw daim ntawv thiab sawb ua tiav yog nyob rau hauv lub tiaj tiaj dov, encompassing kub dov, txias dov, kho cua sov, thiab ua tiav cov txheej txheem. Ua ntej kub dov, hard aluminium alloys yuav tsum tau kev kho mob homogenization ntawm qhov kub me ntsis hauv qab qhov qis -melting- taw tes eutectic kub, tuav rau 12-24 teev, thiab tuaj yeem clad nrog txhuas raws li xav tau, nrog cov cladding txheej thickness kwv yees li 4% ntawm daim ntawv thickness. Kub dov feem ntau ua tiav saum qhov ntsuas kub recrystallization. Cov kab ntau lawm siv ntau- sawv ntsug dov tsis tu ncua, muaj peev xwm ua cov ingots rau hauv 2.5-3.5 hli kub- dov coils nrog tag nrho deformation tus nqi siab tshaj 90%.
Txias dov yog ua nyob rau hauv chav tsev kub, yielding siab -precision, siab- nto- ua kom tiav nyias strips. Ua ke nrog hydraulic nias thiab cov txheej txheem tswj, qhov tseeb qhov tseeb tuaj yeem ncav cuag qib micron. Cov txheej txheem txias dov feem ntau ntiav cov roj lubrication thiab segmented txias kom ntseeg tau tias qhov zoo ntawm qhov chaw thiab strip flatness. Tom qab ua tiav, straightening, thiab theem txheej txheem ntxiv txhim kho qhov seem stability ntawm CNC txhuas qhov chaw. Leveling tom qab quenching yuav tsum tau ua kom tiav nyob rau hauv lub aging incubation lub sij hawm, thiab lub deformation yuav tsum tau tswj nyob rau hauv 2%.
Cov khoom zoo tshaj plaws thiab kev paub tab ua tiav ntawm aluminium alloys ua rau lawv siv dav hauv CNC machined txhuas qhov chaw, cov khoom siv, thiab cov khoom siv ua haujlwm. Los ntawm melting thiab casting mus rau dov thiab sib sau, thiab tom qab ntawd mus rau precision machining, ua tiav cov txheej txheem saw txhawb kev tsim ntau yam ntawm cov khoom siv aluminium alloy thiab tsis tu ncua tsav kev txhim kho ntawm cov qauv sib xyaw ua ke ntawm kev ua haujlwm siab dua thiab kev ua haujlwm siab dua.
