1. Gawo Loyamba: Kusungunula
Aluminiyamu imapangidwa pogwiritsa ntchito magetsi oyeretsera pamlingo wa mafakitale ndipo zosungunulira aluminiyamu zimafunikira mphamvu zambiri kuti zigwire ntchito bwino. Zosungunulira nthawi zambiri zimakhala pafupi ndi malo akuluakulu opangira magetsi chifukwa cha kufunikira kwawo mphamvu. Kukwera kulikonse kwa mtengo wamagetsi, kapena kuchuluka kwa mphamvu komwe kumafunika kuti aluminiyamu ikonzedwe bwino, kumawonjezera mtengo wa ma coil a aluminiyamu. Kuphatikiza apo, aluminiyamu yomwe yasungunuka imapatukana ndikupita kumalo osonkhanitsira. Njirayi imakhalanso ndi zofunikira zazikulu zamphamvu, zomwe zimakhudzanso mitengo yamsika wa aluminiyamu.
2. Gawo Lachiwiri: Kugubuduza Kotentha
Kugubuduza kotentha ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri pochepetsa slab ya aluminiyamu. Pogubuduza kotentha, chitsulo chimatenthedwa pamwamba pa malo obwezeretsanso kuti chisinthe ndikuchipanganso. Kenako, chitsulochi chimadutsa mu ma roll awiriawiri. Izi zimachitika kuti zichepetse makulidwe, zimapangitsa makulidwe kukhala ofanana, komanso kuti makina azikhala abwino. Chophimba cha aluminiyamu chimapangidwa pokonza pepalalo pa madigiri 1700 Fahrenheit.
Njirayi imatha kupanga mawonekedwe okhala ndi magawo oyenera a geometrical ndi mawonekedwe azinthu pomwe ikusunga kuchuluka kwa chitsulo kukhala kofanana. Ntchito izi ndizofunikira kwambiri popanga zinthu zomalizidwa pang'ono komanso zomalizidwa, monga mbale ndi mapepala. Komabe, zinthu zomalizidwa zolimbidwa zimasiyana ndi zolizira zozizira, zomwe zidzafotokozedwa pansipa, chifukwa zimakhala ndi makulidwe ochepa chifukwa cha zinyalala zazing'ono pamwamba.
3. Gawo Lachitatu: Kuzungulira Kozizira
Kuzungulira zitsulo mozizira ndi gawo lapadera la gawo lopanga zitsulo. Njira ya "kuzungulira mozizira" imaphatikizapo kuyika aluminiyamu kudzera m'ma rollers pa kutentha kotsika kuposa kutentha kwake kobwezeretsanso. Kukanikiza ndi kukanikiza chitsulo kumawonjezera mphamvu ndi kuuma kwake. Kuzungulira mozizira kumachitika pa kutentha kowonjezera ntchito (kutentha komwe kuli pansi pa kutentha kwa recrystallization ya chinthu), ndipo kuzunguliza kotentha kumachitika pamwamba pa kutentha kowonjezera ntchito - uku ndiye kusiyana pakati pa kuzunguliza kotentha ndi kuzunguliza kozizira.
Makampani ambiri amagwiritsa ntchito njira yochizira chitsulo yotchedwa cold rolling kuti apange strip ndi sheet metal yokhala ndi final gauge yomwe mukufuna. Mipukutuyi nthawi zambiri imatenthedwa kuti athandize aluminiyamu kugwira ntchito bwino, ndipo mafuta amagwiritsidwa ntchito kuti strip ya aluminiyamu isamamatire ku mipukutuyo. Kuti igwire bwino ntchito, kayendedwe ka mipukutuyo ndi kutentha kwake zimatha kusinthidwa. Mzere wa aluminiyamu, womwe wadutsa kale kutentha, ndi njira zina, kuphatikizapo kuyeretsa ndi kukonza, umaziziritsidwa kutentha kwa chipinda usanayikidwe mu mzere wozizira wa mill mumakampani opanga aluminiyamu. Aluminiyamu imatsukidwa poitsuka ndi sopo ndipo chithandizochi chimapangitsa kuti coil ya aluminiyamu ikhale yolimba mokwanira kuti ipirire kuzizira.
Pambuyo pokonzekera njira izi, mipiringidzo imadutsa mobwerezabwereza kudzera m'ma rollers, zomwe zimataya makulidwe pang'onopang'ono. Ma lattice planes a chitsulocho amasokonekera ndipo amachoka panthawi yonseyi, zomwe zimapangitsa kuti chinthu chomaliza chikhale cholimba komanso cholimba. Kuzungulira mozizira ndi njira imodzi yotchuka kwambiri yolimbitsira aluminiyamu chifukwa imachepetsa makulidwe a aluminiyamu ikaphwanyidwa ndikukankhidwa m'ma rollers. Njira yozizira yozungulira imatha kuchepetsa makulidwe a coil ya aluminiyamu ndi 0.15 mm.
4. Gawo Lachinayi: Kuyika
Njira yothira madzi ndi njira yotenthetsera yomwe imagwiritsidwa ntchito makamaka kuti chinthucho chikhale chofewa komanso cholimba. Kuchepa kwa kusokonekera kwa kapangidwe ka kristalo ka chinthu chomwe chikuthira madzi kumayambitsa kusintha kwa kuuma ndi kusinthasintha kumeneku. Pofuna kupewa kulephera kwa kusweka kapena kuti chinthucho chikhale chogwira ntchito bwino pambuyo pake, kuthira madzi nthawi zambiri kumachitika chinthucho chikauma kapena kuzizira.
Mwa kukonzanso bwino kapangidwe ka kristalo, kulowetsa madzi kumabwezeretsa mapulaneti otsetsereka ndipo kumathandiza kuti gawolo lipangidwenso popanda mphamvu zambiri. Chopangira aluminiyamu cholimba chomwe chimagwiritsidwa ntchito chiyenera kutenthedwa kutentha kwapakati pa 570°F ndi 770°F kwa nthawi yoikidwiratu, kuyambira mphindi makumi atatu mpaka maola atatu. Kukula kwa gawo lomwe likulowetsedwa ndi chopangira chomwe chapangidwacho kumatsimikizira kutentha ndi nthawi zomwe zimafunikira, motsatana.
Kuyikanso zinthu kumalimbitsanso kukula kwa gawo, kumachotsa mavuto omwe amabwera chifukwa cha kupsinjika kwa mkati, komanso kumachepetsa kupsinjika kwa mkati komwe kungabuke, pang'ono, panthawi ya njira monga kupangira zinthu mozizira kapena kuponya. Kuphatikiza apo, zitsulo zotayidwa zomwe sizingathe kuchiritsidwa ndi kutentha zimathanso kuchotsedwa bwino. Chifukwa chake, nthawi zambiri zimagwiritsidwa ntchito pazinthu zotayidwa, zotulutsidwa, kapena zopangidwa ndi aluminiyamu.
Mphamvu ya chinthu kupangidwa imakulitsidwa ndi kutsekereza. Kukanikiza kapena kupindika zinthu zolimba komanso zosweka kungakhale kovuta popanda kusweka. Kutsekereza kumathandiza kuchotsa chiopsezochi. Kuphatikiza apo, kutsekereza kumatha kuwonjezera kulimba kwa makina. Kusweka kwakukulu kwa chinthu kungayambitse kuwonongeka kwakukulu kwa zida. Pogwiritsa ntchito kutsekereza, kuuma kwa chinthu kumatha kuchepa, zomwe zingachepetse kuwonongeka kwa chida. Kutsekereza kulikonse kotsala kumachotsedwa ndi kutsekereza. Nthawi zambiri ndibwino kuchepetsa kupsinjika kotsala kulikonse komwe kungatheke chifukwa kungayambitse ming'alu ndi mavuto ena amakina.
5. Gawo Lachisanu: Kudula ndi Kudula
Ma coil a aluminiyamu angapangidwe mu mpukutu umodzi wautali kwambiri wopitilira. Komabe, kuti aike coil m'mipukutu yaying'ono, amafunika kudulidwa. Kuti agwire ntchito imeneyi, mipukutu ya aluminiyamu imayendetsedwa ndi zida zodulira pomwe masamba akuthwa kwambiri amadula molondola. Mphamvu zambiri zimafunika kuti ntchitoyi ichitike. Ma slitters amagawa mpukutuwo m'zidutswa zazing'ono pamene mphamvu yogwiritsidwa ntchitoyo yapitirira mphamvu yokoka ya aluminiyamu.
Kuti ayambe kudula, aluminiyamu imayikidwa mu chowumitsira. Pambuyo pake, imadutsa mu mipeni yozungulira. Masamba amayikidwa kuti apeze m'mphepete mwa kudula bwino, poganizira m'lifupi ndi malo omwe mukufuna. Kuti atsogolere zinthu zodulazo ku chowumitsira, zinthuzo zimatumizidwa kudzera mu zolekanitsa. Kenako aluminiyamu imakulungidwa ndikukulungidwa mu coil kuti ikonzekere kutumizidwa.
Jindalai Steel Group ndi kampani yotsogola ya aluminiyamu komanso yogulitsa aluminiyamu coil/sheet/plate/strip/pipe/foil. Tili ndi makasitomala ochokera ku Philippines, Thane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar, India ndi zina zotero. Tumizani funso lanu ndipo tidzakhala okondwa kukufunsani mwaukadaulo.
