Aluminium Casting Product ndi Sand Casting

China mwambo zotayidwa aloyi castings ndikuponya mchengandi njira zopangira zipolopolo za nkhungu.

Mawu akuti Green Sand amatanthauza kukhalapo kwa chinyezi mumchenga wowumba ndipo akuwonetsa kuti nkhunguyo siiphika kapena kuuma. Mchenga waiwisi amakumbidwa ndikuukonzedwa kuti ugawidwe mosalekeza wa kukula kwa mbewu. Akamakonzedwa kuti aumbe, amawonjezera dongo kuti amangirire mbewuzo pamodzi.

Fumbi la malasha (lotchedwa Sea Coal) limawonjezedwa kuti liwongolere kutulutsa kwabwino pakukulitsa mchenga pamene zitsulo zotentha zimatsanuliridwa mu nkhungu. Zowonjezera zina, monga pitch, cellulose ndi ufa wa silika, zimagwiritsidwanso ntchito. Zowonjezera zomwe zimagwiritsidwa ntchito zimadalira chitsulo. Mchenga umaphatikizidwa mu mullor kapena chosakaniza, kumene madzi ndi zowonjezera zimagwirizanitsidwa ndi mchenga.

Kenako mchengawo umakhala wokonzeka kugwiritsidwa ntchito kupanga nkhungu. Pali njira zingapo zomangira koma njira zonse zimafinya kapena kuphatikizira mchenga papatani kuti ziwonekere pagawo loponyedwa. Zitsanzozo zimasiyanitsidwa ndi halves ya nkhungu kapena keke ya nkhungu ndipo nkhunguyo imatsekedwa ndikupanga gawo. Mitundu yowumba imayambira pamakina othamanga kwambiri, kuumba mbale zofananira, kuumba kolimba kwa botolo (kumene kumagwiritsidwa ntchito popanga nkhungu zazikulu) ndi kufinya kwa jolt. Zoumba zazikulu zimapangidwiranso pansi ndikuzimanga ndi manja. Masiku ano, kuumba kumangochitika zokha ndipo zojambulajambulazo zimayikidwa pazida zogwiritsira ntchito nkhungu kuti zitsanulidwe, kuti ma castings akhazikike komanso kuti azizizira. Kukonzekera kwa zida zogwiritsira ntchito nkhungu kumaphatikizapo mizere yolozera, mizere yokhotakhota ndi mizere yamagalimoto a nkhungu. Kuthira kwachitsulo kumatha kuchitika kokha ndi ng'anjo yothira kapena kutumizidwa ku zisankho mu ladles. Mphamvu za ladle zimatha kukula kuchokera pa mapaundi 100 mpaka matani angapo.

Pambuyo pakuti chitsulo mu nkhunguyo chalimba ndi kuzizira, nkhunguyo imatayidwa pa shakeout yomwe imalekanitsa zotayira ndi mchenga. The shakeout ndondomeko akhoza kuchitidwa ndi osiyanasiyana zipangizo. Kuponyedwa kumachotsedwa (kusiyanitsidwa ndi dongosolo lothamanga). Dongosolo lothamanga limagwiritsidwa ntchito kulowetsa zitsulo muzitsulo zoponyera. Makina othamanga amatumizidwa ku dipatimenti yosungunula kuti igwiritsidwenso ntchito ndipo zoponyera zimatumizidwa kukamaliza. Mchengawo umagwiritsidwanso ntchito ukaunika ndi kuuzira. Mchenga watsopano umawonjezeredwanso potengera kuchuluka kwa zitsulo zomwe zatsanuliridwa mumchenga womwe waperekedwa.

Kumaliza kuponya kumayamba ndi kuwomberedwa ndi mfuti kuti muchotse mchenga womwe wamamatira pakuponya. Malo omaliza amatha kukhala opangidwa kwambiri, pogwiritsa ntchito ma robot ndi machitidwe a Vision, kapena akhoza kukhala njira yosavuta yogwiritsira ntchito pamanja. Mitundu yodziwika bwino ya ntchito yomaliza imaphatikizapo kugaya magudumu, kugaya lamba, kudula makina osindikizira, kudula macheka, kudula kwa air arch ndi kugaya pamanja. Njira yogwiritsiridwa ntchito imadalira chitsulo choponyera ndi kukula kwa kuponyera.

Aluminiyamu ndi ma aloyi ake amatha kuponyedwa ndikutsanulidwa ndi kuponyera kwamphamvu kwambiri, kuponyera kufa, kuponyera mphamvu yokoka, kuponya mchenga, kuponyera ndalama ndikutaya thovu. Nthawi zambiri, zotayira za aluminiyamu zimakhala zolemera pang'ono koma zimakhala zovuta komanso zowoneka bwino.

Zomwe Aluminiyamu Aloyi Timaponya ndi Njira Yopangira Mchenga:
• Cast Aluminium Alloy by China Standard: ZL101, ZL102, ZL104
• Cast Aluminium Alloy ndi USA Stardard: ASTM A356, ASTM A413, ASTM A360
• Cast Aluminium Alloy ndi Starndards ena: AC3A, AC4A, AC4C, G-AlSi7Mg, G-Al12

Makhalidwe a Aluminium Alloy Castings:
• Kuponyera kumafanana ndi kuponyedwa kwazitsulo, koma mphamvu zamakina zimachepa kwambiri pamene makulidwe a khoma ukuwonjezeka.
• Makulidwe a khoma la ma castings asakhale aakulu kwambiri, ndipo mawonekedwe ena amafanana ndi zitsulo.
• Kulemera kopepuka koma kapangidwe kake
• Ndalama zoponyera pa kilogalamu ya zotayira za aluminiyamu ndizokwera kuposa zachitsulo ndi zitsulo.
• Ngati atapangidwa ndi njira yopangira ufa, mtengo wa nkhungu ndi chitsanzo udzakhala wapamwamba kwambiri kuposa njira zina zoponyera. Chifukwa chake, ma aluminiyamu oponyera mafelemu atha kukhala oyenera kuponyedwa mochuluka kwambiri.
