1. Danho Rokutanga: Kunyunguduka
Aluminium inogadzirwa pachishandiswa electrolysis pachiyero cheindasitiri uye maaruminiyamu anonyungudutsa anoda simba rakawanda kuti afambe nemazvo. Zvinyungudutsa zvinowanzowanikwa padhuze nemagetsi makuru nekuda kwekuda kwavo simba. Chero kuwedzera kwemutengo wesimba, kana huwandu hwesimba rinodiwa kukwenenzvera aruminiyamu kusvika kugiredhi repamusoro, rinowedzera mutengo wemakoiri ealuminium. Mukuwedzera, aluminium yakanyungudutswa inoparadzanisa uye inoenda kunzvimbo yekuunganidza. Iyi tekinoroji ine zvakare yakawandisa simba rinodiwa, iro rinokanganisa mitengo yemusika wealuminium zvakare.
2. Nhanho Yechipiri: Kupisa Kuputika
Kupisa kunopisa ndiyo imwe yenzira dzinowanzo shandiswa kuonda aluminium slab. Mukupisa kukungurutswa, simbi inopisa pamusoro peiyo poindi yerecrystallization kuti iparadze uye kuwedzera kuiumba. Zvadaro, iyi simbi yesimbi inopfuudzwa kuburikidza imwe kana kupfuura peya yemapumburu. Izvi zvinoitirwa kudzikisira ukobvu, kugadzira ukobvu yunifomu, uye kuwana inodiwa michina mhando. Iyo aluminium coil inogadzirwa nekugadzirisa pepa pa1700 degrees Fahrenheit.
Iyi nzira inogona kugadzira maumbirwo ane akakodzera geometrical paramita uye hunhu hwezvinhu uku uchichengeta vhoriyamu yesimbi isingachinji. Aya ma operation akakosha mukugadzira semi-akapedza uye apedzwa zvinhu, senge mahwendefa nemashiti. Nekudaro, zvigadzirwa zvakapedzwa zvakapedzwa zvakasiyana kubva kuchando akakungurutswa coils, izvo zvichatsanangurwa pazasi, pakuti ivo vane kushoma yunifomu ukobvu nekuda kwemarara madiki ari pamusoro.
3. Danho rechitatu: Cold Rolling
Cold rolling yesimbi mitsetse inzvimbo yakasarudzika yesimbi yesimbi. Maitiro e "cold rolling" anosanganisira kuisa aluminiyamu kuburikidza nema rollers pane tembiricha yakaderera pane yayo recrystallization tembiricha. Kudzvanya nekudzvanya simbi kunowedzera simba regoho nekuoma kwayo. Cold rolling inoitika pakushanda-kuoma tembiricha (tembiricha iri pazasi recrystallization tembiricha), uye inopisa kukungurutswa kunoitika pamusoro pebasa rinoomesa tembiricha- uyu ndiwo mutsauko uripo pakati pekukunguruka uye kutonhora kukunguruka.
Maindasitiri mazhinji anoshandisa nzira yekurapa simbi inozivikanwa sechando rolling kugadzira tambo uye sheet simbi ine inodiwa geji yekupedzisira. Mipumburu yacho inowanzodziyirwa kubatsira aluminium kuti ishande zvakanyanya, uye mafuta ekuzora anoshandiswa kudzivirira tambo yealuminium kuti isanamatira kumapumburu. Kuti ushande zvakanaka-tuning, kufamba kwemaroll uye kupisa kunogona kuchinjwa. Aluminium strip, iyo yakatoitwa kupisa inopisa, uye mamwe maitiro, anosanganisira kuchenesa nekurapa, inotonhodzwa kusvika mukamuri tembiricha isati yaiswa mumutsara unotonhora weguyo muindasitiri yealuminium. Aluminium inocheneswa nekuisukurudza nedetergent uye kurapwa uku kunoita kuti coil yealuminum inyanye kushingirira kutenderedzwa nechando.
Mushure mekunge matanho ekugadzirira aya agadziriswa, mitsetse inodzokororwa nzira kuburikidza nema rollers, zvishoma nezvishoma ichirasikirwa nekukora. Ndege dzemarata dzesimbi dzinovhiringwa uye dzakamiswa-munguva yese, izvo zvinoguma nekuoma, kusimba kwekupedzisira chigadzirwa. Cold rolling ndeimwe yenzira dzinonyanya kufarirwa dzekuomesa aruminiyamu nekuti inoderedza ukobvu hwearuminiyamu ichipwanywa nekusundirwa nemuma roller. Nzira inotonhora yekukungurusa inogona kuderedza ukobvu hwealuminium coil nekusvika 0.15 mm.
4. Danho rechina: Annealing
An annealing process mushonga wekupisa unoshandiswa kunyanya kuita kuti chinhu chinyanye kuumbika uye kusaomarara. Kudzikira kwekutsemuka muchimiro chekristaro chechinhu chiri kunyungudutswa chinokonzera shanduko iyi mukuoma uye kuchinjika. Kuti udzivise kutadza kutadza kana kuita kuti chinhu chishande zvakanyanya pakutevera maoparesheni, annealing inowanzoitwa mushure mekunge chinhu chaomeswa kana kutonhora kushanda.
Nekunyatsogadzirisa chimiro chekristaro chezviyo, annealing inodzoreredza ndege dzinotsvedza uye inogonesa kuwedzera kuumbwa kwechikamu pasina simba rakawandisa. A aluminium alloy yekushanda-yakaomeswa inofanira kupiswa kune imwe tembiricha iri pakati pe570°F ne770°F kwenguva yakafanotemerwa, kubva pamaminitsi angangoita makumi matatu kusvika kumaawa matatu. Saizi yechikamu chiri kuvharwa uye alloy iyo inogadzirwa nekuona tembiricha uye nguva zvinodiwa, zvichiteerana.
Annealing zvakare inodzikamisa mativi echikamu, inobvisa matambudziko anounzwa nemukati madhindindi, uye inoderedza kushushikana kwemukati kunogona kumuka, muchidimbu, panguva yemaitiro senge kutonhora kwekugadzira kana kukanda. Pamusoro pezvo, aruminiyamu alloys asingabatike kupisa anogona zvakare kubudirira kuvharwa. Naizvozvo, inowanzo shandiswa kukanda, extruded, kana forged aruminiyamu zvikamu.
Kugona kwechinhu kuumbwa kunowedzerwa nekunamira. Kudzvanya kana kukotama zvakaoma, zvinhu zvinoputika zvinogona kunetsa pasina kukonzera kutyoka. Annealing inobatsira kubvisa njodzi iyi. Uyezve, kuvharidzira kunogona kuwedzera machinability. Kunyanya brittleness yechinhu kunogona kukonzera kupfeka kwakanyanya kwemidziyo. Kuburikidza neannealing, kuoma kwechinhu kunogona kudzikiswa, izvo zvinogona kuderedza kupfeka kwemidziyo. Chero kusawirirana kwasara kunopedzwa neannealing. Zvinowanzoita zvakanaka kuderedza kusawirirana kwasara pese pazvinogoneka nekuti zvinogona kutungamira mukutsemuka uye dzimwe nyaya dzemuchina.
5. Nhanho yechishanu: Kucheka uye Kucheka
Aluminium coils inogona kugadzirwa mune imwe yakareba kwazvo inoenderera roll roll. Kuti utakure coil mumapumburu madiki, zvisinei, anoda kuchekwa. Kuti uite basa iri, maaruminiyamu rolls anofambiswa kuburikidza nekutsemura midziyo uko mashizha akapinza zvinoshamisa anoita kucheka chaiko. Simba rakawanda rinodiwa kuita oparesheni iyi. Slitters inotsemura mupumburu kuita zvidimbu zvidiki kana simba rinoshandiswa richipfuura simba realuminium.
Kuti utange kutsemura, iyo aluminium inoiswa muuncoiler. Pashure pacho, inopfuudzwa nepakati peseti yemapanga anotenderera. Iwo mablades akamisikidzwa kuti awane yakanakisa slit mupendero, tichifunga nezvehupamhi hunodiwa uye clearance. Kutungamira iyo slit zvinhu kune recoiler, izvo zvinhu zvinozodyiswa kuburikidza nevanoparadzanisa. Iyo aluminiyamu inobva yaunganidzwa uye yakaputirwa mucoil kugadzirira kutumirwa.
Jindalai Steel Group ndiyo Inotungamira Aluminium Kambani uye Mutengesi wealuminium coil/sheet/plate/strip/pipe/foil. Tine mutengi kubva kuPhilippines, Thane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar, India etc. Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
