Chidule cha Aluminium Ingot Casting Process

I. Chiyambi

Ubwino wa aluminiyumu yoyambirira yopangidwa m'maselo a aluminiyamu electrolytic umasiyana kwambiri, ndipo imakhala ndi zonyansa zosiyanasiyana zachitsulo, mpweya, ndi zosakanikirana zopanda zitsulo. Ntchito ya aluminium ingot casting ndikuwongolera kagwiritsidwe ntchito kamadzimadzi otsika kwambiri a aluminiyamu ndikuchotsa zonyansa momwe zingathere.

II. Gulu la Aluminium Ingots

Ingots za aluminiyamu zimagawidwa m'mitundu itatu kutengera kapangidwe kake: ma ingots osungunuka, ma aluminiyamu oyeretsedwa kwambiri, ndi aluminum alloy ingots. Athanso kugawidwa molingana ndi mawonekedwe ndi kukula kwake, monga ma slab ingots, ingots yozungulira, ingots ya mbale, ndi ingots zooneka ngati T. Pansipa pali mitundu ingapo yodziwika bwino yazitsulo za aluminiyamu:

Ingots zosungunula: 15kg, 20kg (≤99.80% Al)

Ingots zooneka ngati T: 500kg, 1000kg (≤99.80% Al)

Zida za aluminiyamu zoyera kwambiri: 10kg, 15kg (99.90% ~ 99.999% Al)

Aluminiyamu aloyi ingots: 10kg, 15kg (Al-Si, Al-Cu, Al-Mg)

Zingwe za mbale: 500 ~ 1000kg (zopanga mbale)

Zingwe zozungulira: 30 ~ 60kg (zojambula waya)

III. Njira ya Aluminium Ingot Casting

Kupopa kwa aluminiyamu—Kuchotsa zinyalala—Kuyendera kulemera—Kusakaniza kwa zinthu—Kuthira ng’anjo—Kuyenga—Kuponya—Nyingi zosungunula—Kuyendera komaliza—Kuyendera kulemera komaliza—Kusungirako

Kupopa kwa aluminiyamu—Kuchotsa zinyalala—Kuyendera kulemera—Kusakaniza zinthu—Kuthira ng’anjo—Kuyenga—Kuponyera—Kuponyera—Nyingi za aloyi—Kuponyera nsonga za aloyi—Kuyendera komaliza—Kuyendera kulemera komaliza—Kusungirako

IV. Kuponya Njira

Njira yopangira aluminium ingot yomwe ilipo masiku ano imagwiritsa ntchito njira yothira, pomwe madzi a aluminiyamu amathiridwa mu nkhungu ndikuloledwa kuzizirira asanatulutsidwe. Ubwino wa mankhwalawa umatsimikiziridwa makamaka pa sitepe iyi, ndipo njira yonse yoponyera ikuzungulira gawo ili. Kuponya ndi njira yoziziritsira aluminiyamu yamadzimadzi ndikuyiyika muzitsulo zolimba za aluminiyamu.

1. Kuponya Mopitiriza

Kuponyera kosalekeza kumaphatikizapo njira ziwiri: kuponyera ng'anjo yosakanikirana ndi kuponyera kunja, zonse pogwiritsa ntchito makina oponyera mosalekeza. Kuponyera ng'anjo yosakanizidwa kumaphatikizapo kuthira madzi a aluminiyamu mu ng'anjo yosakanizidwa kuti aponyedwe ndipo amagwiritsidwa ntchito makamaka popanga ma ingots osungunuka ndi aloyi. Kuponyera kunja mwachindunji kumathira kuchokera ku crucible kupita ku makina oponyera ndipo kumagwiritsidwa ntchito pamene zida zoponyera sizingakwaniritse zofunikira zopanga kapena pamene zinthu zomwe zikubwera sizili bwino.

2. Oyima Semi-Kupitilira Kuponya

Kuponyera kopitilira muyeso kumagwiritsidwa ntchito makamaka popanga ma waya a aluminiyamu, ma ingots a mbale, ndi ma aloyi osiyanasiyana opindika pokonza. Pambuyo posakaniza zinthu, madzi a aluminiyumu amatsanuliridwa mu ng'anjo yosakanikirana. Pazitsulo zamawaya, chimbale chapadera cha Al-B chimawonjezedwa kuti chichotse titaniyamu ndi vanadium kumadzi a aluminiyamu musanaponye. Mawonekedwe apamwamba a waya wa aluminiyamu ayenera kukhala osalala popanda slag, ming'alu, kapena pores mpweya. Kuphulika kwa pamwamba sikuyenera kukhala kotalika kuposa 1.5mm, makwinya a slag ndi m'mphepete mwake sayenera kupitirira 2mm mozama, ndipo gawolo liyenera kukhala lopanda ming'alu, ma pores a gasi, ndipo osapitirira 5 slag inclusions yaying'ono kuposa 1mm. Kwa ingots ya mbale, alloy Al-Ti-B (Ti5% B1%) amawonjezeredwa kuti ayeretsedwe. Kenako zokhomedwazo zimaziziritsidwa, kuchotsedwa, kuchekedwa molingana ndi miyeso yofunikira, ndi kukonzekera kuti zidzachitikenso kaye.
