Aluminium alloy yog dav hlub los ntawm tuag-casting factories vim nws cov yam ntxwv uas nws yuav siv tau nyob rau hauv ntau qhov chaw thiab qhia tau hais tias zoo heev siv cov teebmeem. Zoo aluminium alloy tuag-casting qhov chaw muaj lub neej ua haujlwm ntev thiab muaj zog thiab ruaj khov, tab sis tseem, Professional die-casting yuav tsum tau ua raws.
Lub casting ntawm aluminium alloy tuag castings yuav tsum ua raws li cov cai:
- Casting ceev: Lub casting ceev ntawm aluminium alloy tuag castings yog ncaj qha proportional rau cov kua kab noj hniav ntawm lub ingot. Yog hais tias qhov ceev nrooj nce, cov kua kab noj hniav thiab qhov kub thiab txias ntawm cov ingot yuav nce, thiab cov kab noj hniav ntawm cov kua yuav tshwm rau hauv qab ntawm cov kab noj hniav, uas ua rau muaj kev ntxhov siab loj, uas yuav ua rau qhov tshwm sim ntawm kub tawg hauv cov kab noj hniav. ingot, yog li Peb yuav tsum tswj qhov ceev.
- Cov castings yuav tsum ua tau raws li cov kev cai cuam tshuam los yog qhov ntev thiab qhov sib txawv uas yuav tsum tau ua los ntawm kev kos duab lossis qauv muab los ntawm tus neeg yuav khoom.
- Castings tsis tuaj yeem xau los ntawm hammering, ntsaws, lossis dipping.
- Ua kua theem siab: Txoj hauj lwm ntawm cov kua theem kuj tseem ceeb heev. Yog tias nws tsawg dhau, nws yuav ua rau cov thermal tawg ntawm cov khoom siv, thiab yog tias nws hnyav, nws yuav cuam tshuam rau cov txheej txheem casting. Yog hais tias cov kua theem siab dhau lawm, cov degree ntawm segregation ntawm lub ingot yuav nce. Yog li ntawd, yuav tsum muaj cov kua dej tsim nyog, thiab nws yuav tsis ua haujlwm yog tias nws siab dhau lossis qis dhau.
- Castings yuav tsum tsis txhob muaj qhov tsis xws luag xws li tawg, txias kaw, xuab zeb qhov, pores, slag qhov, shrinkage porosity, thiab oxidized slag inclusions.
- Casting kub: Qhov kub thiab txias zoo ntawm aluminium alloy tuag castings yuav ua kom cov hlau ua kua hauv qhov dej zoo, yog li txo cov ntaub so ntswg kev ntxhov siab thiab tiv thaiv cov kab nrib pleb.
- Kev ntsuas kub ntawm qhov ntsuas kub yuav tsum tau txiav txim siab raws li hom khoom thiab cov lus qhia ntawm cov khoom siv. Yog tias qhov ntsuas kub tsis tsim nyog, nws yuav ua rau muaj kev ntxhov siab sab hauv, ua rau tawg lossis tawg hauv qhov casting. Yog tias qhov ntsuas kub qis dhau, nws tsis zoo, vim tias nws yuav ua rau muaj qhov tsis xws luag xws li txias kaw, slag suav nrog, thiab txawm tias tawg ntawm qhov chaw ntawm qhov chaw. Yog tias nws loj heev, nws yuav ua rau cov casting tsis tuaj yeem txuas ntxiv mus.
- Qhov tsis ua tiav ntawm qhov casting yuav tsum du thiab tiaj tus, thiab cov cim casting yuav tsum tau meej. Tom qab ntxuav lub pouring thiab riser, nws yuav tsum tau yaug nrog lub nto ntawm lub casting.
Dab tsi yog qhov cuam tshuam ntawm ntau yam ntawm aluminium alloy tuag castings?
- Hlau: Thaum cov ntsiab lus hlau qis dua 6 feem pua, nws tuaj yeem txo qhov adhesion ntawm pwm.
- Titanium: Nws tuaj yeem kho cov qauv ntawm cov khoom siv lead ua, txhim kho tus cwj pwm, thiab txo cov suab nrov ntawm alloy kub tawg. Rau kev ntim khoom ntawm aluminium alloy tuag-casting khoom, qhov tseem ceeb tshaj plaws yog los tiv thaiv cov khoom sab hauv, tab sis qhov zoo nkauj ntawm lub thawv ntim kuj yog ib yam uas peb yuav tsum xav txog.
- Silicon: Nws yog ib qho tseem ceeb hauv aluminium alloys. Nws tuaj yeem txhim kho cov khoom pov thawj ntawm cov alloys, thiab silicon thiab aluminium tuaj yeem tsim cov kev daws teeb meem.
- Manganese: Manganese tuaj yeem txo cov kev cuam tshuam ntawm cov hlau hauv aluminium alloys, tig hlau flakes rau hauv cov koob zoo li cov khoom zoo li pawg, 5 feem pua yog nruab nrab.
- Magnesium: Peb qhov kev hloov pauv thiab ib qho kev nce ntxiv tuaj yeem ntxiv kom muaj zog thiab kev pom zoo, kev ua haujlwm, thiab ua haujlwm ntev.
- Nickel: Nws tuaj yeem ua kom muaj zog thiab tawv, thiab nws tsis ntshai ntawm corrosion thaum zawv zawg, thiab nws yog tib yam li hlau.
- Zinc: Zinc muaj fluidity, nce tab sis tsis txo qis kub brittleness, thiab stabilizes thiab txo qis tsis ntshai ntawm corrosion.
Kev sib piv ntawm aluminium alloy thiab aluminium
Peb paub tias cov khoom tseem ceeb ntawm aluminium alloy yog txhuas, tooj liab, magnesium, thiab silicon. Txhawm rau txhim kho cov yam ntxwv ntawm aluminium, peb ntxiv cov ntsiab lus no los txhim kho kev siv cov khoom siv. Cia peb saib cov kev hloov pauv tom qab ntxiv cov ntsiab lus aluminium rau aluminium alloy:
- Lub zog thiab hardness: Ntxiv cov khoom tsim nyog alloying tuaj yeem txhim kho lub zog thiab hardness ntawm aluminium alloy tuag castings. Cov ntsiab lus alloying xws li tooj liab, magnesium, thiab zinc tuaj yeem tsim cov tshuaj tiv thaiv kom muaj zog lossis nag lossis daus ntxiv rau theem kom muaj zog tensile thiab hardness ntawm alloy.
- Toughness thiab cuam tshuam tsis kam: Qhov sib ntxiv ntawm qee yam alloying ntsiab tuaj yeem txhim kho toughness thiab cuam tshuam tsis kam ntawm aluminium alloy tuag castings. Piv txwv li, cov ntsiab lus xws li tooj liab thiab magnesium tuaj yeem txhim kho cov tawv tawv ntawm aluminium alloys, ua rau lawv ductile thiab cuam tshuam-resistant thaum muaj kev ntxhov siab.
- Corrosion kuj: Tsim nyog alloying ntsiab tuaj yeem txhim kho corrosion kuj ntawm aluminium alloy tuag castings, ua rau lawv ruaj khov nyob rau hauv ib puag ncig hnyav. Piv txwv li, ntxiv zinc tuaj yeem txhim kho corrosion kuj ntawm aluminium alloy, ua kom nws muaj kev tiv thaiv corrosion zoo dua hauv cov dej noo lossis tshuaj lom neeg.
- Processability: Tsim nyog alloying ntsiab tuaj yeem txhim kho cov txheej txheem ntawm aluminium alloy tuag castings. Piv txwv li, qhov sib ntxiv ntawm silicon tuaj yeem txhim kho lubricity ntawm aluminium alloys thiab txo cov coefficient ntawm kev sib txhuam, ua rau nws yooj yim dua rau txhuas alloys los sau pwm kab noj hniav thiab tau zoo dua nto zoo.
- Kev kho cua sov teb: Cov alloying sib txawv muaj cov lus teb sib txawv rau kev kho cua sov. Qhov sib ntxiv ntawm qee cov ntsiab lus alloying tuaj yeem txhim kho cov txiaj ntsig kev kho cua sov ntawm aluminium alloys, xws li kev txhim kho cov kuab tshuaj thiab nag lossis daus, ntxiv dag zog rau kev ua haujlwm ntawm cov khoom siv.
Cov ntaub ntawv aluminium alloy sib txawv muaj qhov sib txawv ntawm cov khoom sib txawv thiab cov ntsiab lus sib txawv. Cov kev xaiv tshwj xeeb ntawm cov ntsiab lus alloying tsim nyog yuav tsum tau ua kom tiav raws li daim ntawv thov, cov khoom siv kho tshuab, thiab kev ua haujlwm ntawm aluminium alloys. Peb lub tuam txhab MindWell muaj kev paub dhau los thiab kev paub zoo tshaj plaws thiab tuaj yeem muab cov lus qhia sib xws thiab kev daws teeb meem raws li cov neeg siv khoom xav tau.
