Tuag casting yog txheej txheem ntawm hlau smelting thiab ua. Nws yog ib txoj kev casting uas molten alloy kua yog ntim rau hauv kab noj hniav ntawm ib tug steel pwm ntawm kev kub ceev nyob rau hauv qhov kev txiav txim ntawm kev kub siab, thiab cov kua alloy yog solidified nyob rau hauv siab los tsim ib tug casting. Nws zoo ib yam li "Plastic Txhaj Molding". Cov yam ntxwv tseem ceeb uas paub qhov txawv tuag casting los ntawm lwm txoj kev casting yog kev kub siab thiab kev kub ceev.
1. Dab tsi yog cov yam ntxwv ntawm aluminium alloy tuag-casting khoom?
1. Aluminium alloys tuaj yeem muab faib ua
Plaub hom: xeb-pov thawj txhuas (LF), tawv txhuas (LY), super-hard aluminium (LC) thiab forged txhuas (LD)
2. Cast aluminium alloys muab faib ua ntau hom raws li cov ntsiab lus alloying tseem ceeb ntxiv.
Muaj plaub hom txhuas-silicon series (AL-Si), txhuas-tooj liab series (Al-Cu), txhuas-magnesium series (Al-Mg) thiab txhuas-zinc series (Al-Zn).
Feem ntau siv hom xws li ADC12 (A383), ADC10 (A380)
3. Qhov zoo ntawm aluminium alloy tuag casting
Cov khoom zoo: castings muaj qhov siab qhov tseeb, zoo nto tiav, siab zog thiab hardness. Lub zog feem ntau yog 25 ~ 30% siab dua li cov xuab zeb casting, tab sis qhov elongation yog txo los ntawm 70%. Cov castings yog dimensionally ruaj khov thiab muaj zoo interchangeability. Nws tuaj yeem tuag-cam khwb cia aluminium nyias-walled thiab complex castings. Piv txwv li, cov phab ntsa me me tam sim no ntawm zinc alloy tuag-casting tuaj yeem ncav cuag 0.3mm, thiab aluminium alloy tuag-casting tuaj yeem ncav cuag 0.5mm. Kev ua haujlwm siab ntau lawm: Lub tshuab muaj kev tsim khoom siab. Piv txwv li, lub domestic JIII3 kab rov tav txias cua tuag-casting txhuas tshuab tuaj yeem tuag-cam khwb cia txhuas 600 mus rau 700 npaug ntawm qhov nruab nrab hauv yim teev, thiab lub me me kub chamber tuag-casting txhuas tshuab tuaj yeem tuag-cam khwb cia txhuas 3,{{19} } mus rau 7,000 zaug hauv yim teev nyob rau nruab nrab. Cov txiaj ntsig zoo ntawm kev lag luam: Vim qhov loj ntawm qhov tuag-cam khwb cia txhuas qhov chaw, qhov chaw du thiab huv si. Feem ntau, nws tsis yog mechanically tiav lawm tab sis siv ncaj qha, los yog tus nqi ntawm kev ua yog me me, yog li nws tsis tsuas yog txhim kho cov hlau siv tus nqi, tab sis kuj txo cov khoom siv ntau thiab cov txiv neej-teev. Cov castings yog pheej yig, thiab ua ke txhuas tuag-cam khwb cia yuav siv tau nrog lwm yam hlau los yog non-metallic cov ntaub ntawv. , txuag ob lub sijhawm sib dhos thiab hlau.
