Aluminium Copper Alloy Casting

Alloys nrog aluminium thiab tooj liab raws li cov khoom tseem ceeb yog hu ua aluminium-tooj ​​liab alloys. Casting aluminium-tooj ​​liab alloys yog feem ntau ua rau casting defects xws li shrinkage tawg thiab tsis zoo filling; Qhov no yog vim muaj cov ntsiab lus tooj liab siab, tsis muaj fluidity ntawm aluminium yaj, thiab alloys. Muaj ib tug loj mushy solidification tshwm sim nyob rau hauv lub solidification txheej txheem; txoj kev tsim nyog tshaj plaws yuav tsum raug txiav txim raws li cov qauv casting tshwj xeeb, thiab cov txheej txheem tsim nyog rau cov txheej txheem casting sib txawv kuj txawv. Qinhuangdao Zhongwei Precision Machinery Co., Ltd. Tom qab ntau tshaj xyoo ntawm nag los nag, peb muaj kev nplua nuj nyob rau hauv zus tau tej cov txhuas alloy castings, silicon aluminium alloy castings, txhuas tooj liab alloy castings, aluminium magnesium alloy castings, txhuas bronze castings thiab lwm yam castings. . Cov neeg tsim khoom los ntawm ntau lub teb chaws yuav tsum nug txog aluminium tooj liab alloy casting.

Txheej txheem ntau lawm

Cov ntsiab lus tseem ceeb ntawm cov txheej txheem ntawm smelting ZL201 alloy yog: nruj me ntsis tswj cov tshuaj muaj pes tsawg leeg thiab impurity cov ntsiab lus los tiv thaiv titanium segregation thiab hauv qab sinking. Vim li no, aluminium ingots nrog purity siab dua yuav tsum tau siv, thiab cov khoom xa rov qab yuav tsum tsis pub tshaj 60 feem pua. Thaum batching, nws yog ib qho tsim nyog yuav tsum paub qhov tseeb melting tus nqi ntawm txhua lub caij, thiab xyuas cov hlau thiab silicon cov ntsiab lus. Cov kev ntsuas thev naus laus zis los tiv thaiv thiab tshem tawm kev sib cais ntawm titanium yog raws li hauv qab no.

(1) Nws tsis raug tso cai siv cov khoom tsis sib xws thiab cov flakes loj. los yog tsis zoo metallurgical

Master alloy; cov ntsiab lus titanium yog tswj los ntawm {{0}}.15 feem pua ​​​​thiab 0.30 feem pua ​​​​thaum batching.

(2) Ua kom muaj zog nplawm thaum smelting, thiab sim siv qhov cub induction rau smelting.

(3) Sim ua kom luv lub sij hawm tuav los ntawm nplawm mus rau casting, tsis pub ntau tshaj 20 mus rau 30 feeb.

ZL201 alloy yog rhiab heev rau impurities hlau thiab silicon. Nws yog qhov zoo tshaj plaws los siv lub graphite crucible, uas yuav tsum tau ntxuav thiab preheated ua ntej noj.

Copper, manganese thiab titanium feem ntau ntxiv rau hauv daim ntawv ntawm Al-Cu, Al-Mn, Al-Ti master alloys, thiab titanium kuj ntxiv tau. Txhawm rau kom tau txais cov hlau alloy nrog qhov tseeb muaj pes tsawg leeg thiab siab metallurgical zoo, cov txheej txheem thib ob feem ntau yog siv. Ua ntej, lub prefabricated alloy ingot yog melted, thiab lub thib ob yog sai melted. Tom qab kho qhov muaj pes tsawg leeg, nws yog cam khwb cia. Nyob rau hauv cov xwm txheej uas cov txheej txheem smelting yog paub tab, cov alloy muaj pes tsawg leeg yuav raug tswj kom raug, thiab cov alloy zoo yog guaranteed, lub prefabricated ingot yuav raug tshem tawm.

Aluminium-tooj ​​liab binary alloys yog yooj yim los tsim dua lwm yam cam khwb cia txhuas alloys. Cov hlau no tuaj yeem yaj hauv crucibles, nplaim taws reverberatory furnaces thiab hluav taws xob furnaces ntawm ntau yam configurations. Aluminium-tooj ​​liab alloys tsis yooj yim rau nqus pa li aluminium-silicon alloys, thiab lawv tsis yooj yim rau oxidize zoo li alloys nrog siab magnesium ntsiab lus. Aluminium ingots ntawm qib A3 thiab hauv qab no thiab tooj liab ntawm qib 3 (M3) thiab nws 'F tau siv los ua tus nqi rau txhuas-tooj ​​liab alloy. Copper yog ntxiv rau aluminium-tooj ​​liab alloy nyob rau hauv daim ntawv ntawm ib tug txhuas-tooj ​​liab master alloy. Cov txhuas-tooj ​​liab eutectic alloy uas muaj 33 feem pua ​​​​tooj liab muaj tag nrho cov khoom ntawm ib qho zoo heev master alloy: nws tuaj yeem ua rau hauv fusible (melting point 540 degree) thiab nkig alloy nrog cov tshuaj muaj pes tsawg leeg. Txawm li cas los xij, cov alloys uas muaj 50 feem pua ​​​​tooj liab muaj qhov zoo dua. Ntawm qhov qis melting point (575 degree) thiab txaus brittleness, no alloy yog homogeneous.

Muaj peb txoj hauv kev ua cov aluminium-tooj ​​liab master alloy: (1) sib xyaw molten aluminium thiab tooj liab; (2) dissolving tooj liab nyob rau hauv molten aluminium; (3) dissolving aluminium hauv molten tooj liab. Ntawm peb txoj kev no, txoj kev thib peb yog qhov ua tau zoo tshaj plaws vim tias nws yooj yim thiab lav qhov zoo ntawm tus tswv alloy.

Cov txheej txheem ntawm dissolving tooj liab nyob rau hauv molten aluminium thiab cov txheej txheem ntawm kev sib tov molten hlau ua rau tus tswv alloy susceptible mus paug los ntawm non-metallic impurities vim khaus overheating ntawm cov smelt. Qhov sib ntxiv ntawm preheated khoom tooj liab los yog molten tooj liab rau molten aluminium induces ib tug tseem ceeb kub nce vim lub dissipation ntawm tshav kub generated los ntawm cov txhuas-tooj ​​liab alloy. Kev sib xyaw ua ke cais cov hlau melted, ntxiv rau overheating cov hlau, ua rau cov txheej txheem ntau lawm ua rau ob lub cub tawg, crucibles, thiab lwm yam. Txawm li cas los xij, thaum fusing ntau ntawm cov tswv alloys hauv cov foundries loj, txoj kev no ua rau muaj kev nkag siab zoo. Nyob rau hauv txoj kev no, cov tooj liab thiab ib feem ntawm cov txhuas yog melted nyias nyob rau hauv lub charcoal cladding. Cov molten tooj liab tau nchuav rau hauv cov molten aluminium hauv cov kwj deg, thiab cov seem ntawm cov khoom txhuas tau ntxiv rau hauv cov khoom siv txhawm rau txo qhov kub ntawm cov smelt. Thaum cov khoom txhuas yaj hauv cov kua tooj liab, cov cua kub ntawm cov smelt txo qis heev. Qhov no yog vim lub peev xwm kub ntau dua thiab latent cua sov ntawm fusion ntawm tooj liab dua li ntawm tooj liab. Txawm li cas los xij, kev siv txoj kev quab yuam no tsis zam qhov muaj peev xwm ntawm lub zos overheating ntawm cov smelt. Txhawm rau kom tsis txhob muaj cua sov hauv cheeb tsam, aluminium yog ntxiv tob hauv qab ntawm lub pas dej molten thiab yaj hauv cov kua tooj liab.

Cov txheej txheem ntawm dissolving khoom tooj liab nyob rau hauv molten tooj liab los ua Al-Cu master alloy yog cov ntsiab lus raws li nram no: tag nrho cov tooj liab raug them rau hauv lub cub tawg, thiab 10 ~ 15 feem pua ​​​​ntawm tag nrho cov txhuas ntawm tus nqi yog ntxiv los ua kom lub melting ntawm tooj liab. Cov txhuas tau ntxiv me me raws li cov tooj liab yaj, ntxiv cov txhuas rau hauv qhov tob ntawm lub pas dej molten thiab sib tov cov smelt ntawm qhov no. Aluminium ingot yuav tsum tau preheated rau 150 ~ 200 degree. Tom qab tag nrho cov txhuas yog yaj, cov hlau yog smelted mus rau 700 degree thiab refined nrog zinc chloride, lub slag raug tshem tawm, thiab lub resulting master alloy yog cam khwb cia rau hauv preheated ingot pwm ntawm 680-700 degree . Thaum tus tswv alloy yog solidified nyob rau hauv lub ingot pwm, zaj duab xis tsim nyob rau saum npoo yog muab tshem tawm nrog ib tug ladle, thiaj li hais tias cov roj tso tawm los ntawm nws raws li cov hlau solidifies thiab cov non-metallic paug nyob rau saum npoo yuav raug tshem tawm.

Daim ntawv thov

Copper alloys yog aluminium alloys nrog tooj liab ua lub ntsiab alloying, suav nrog txhuas-tooj ​​liab-magnesium alloys, aluminium-tooj ​​liab-magnesium-hlau-nickel alloys, thiab aluminium-tooj-manganese alloys, uas tuaj yeem ua kom muaj zog los ntawm kev kho cua sov. Aluminium tooj liab alloy casting muaj qhov ua haujlwm zoo thaum tshav kub kub thiab kev ua haujlwm, tab sis nws cov corrosion kuj tsis zoo li ntawm lwm cov txhuas alloys. Nyob rau hauv tej yam kev mob, intergranular corrosion yuav tshwm sim. Yog li ntawd, lub phaj feem ntau yuav tsum tau coated nrog ib txheej ntawm ntshiab txhuas los yog 6 series txhuas alloy. Txhim kho corrosion kuj. Ntawm lawv, cov txhuas-tooj ​​liab-magnesium-hlau-nickel alloy muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab theem muaj pes tsawg leeg. Nws muaj lub zog siab ntawm qhov kub thiab txias thiab kev ua haujlwm zoo. Nws yog tsuas yog siv rau qhov kub-resistant qhov chaw uas ua haujlwm hauv qab 150 txog 250 degrees Celsius. Txawm hais tias chav tsev kub lub zog ntawm aluminium-tooj ​​liab-manganese alloy yog qis dua li ntawm aluminium-tooj ​​liab-magnesium alloy, lub zog siab dua li ob ntawm 225 txog 250 degrees Celsius lossis siab dua, thiab cov alloy muaj cov txheej txheem zoo thiab yog ib qho yooj yim rau weld. Nws yog tsuas yog siv nyob rau hauv tshav kub-resistant weldable alloys. Structure qhov chaw thiab forgings.
