1. Inyathelo Lokuqala: Ukunyibilikisa
I-aluminium yenziwa kusetyenziswa i-electrolysis kwizinga lemizi-mveliso kwaye abanyibilikisi be-aluminium bafuna amandla amaninzi ukuze basebenze ngokufanelekileyo. Abanyibilikisi bahlala bekufutshane nezikhulu zamandla ngenxa yesidingo sabo samandla. Nakuphi na ukunyuka kwexabiso lamandla, okanye ubungakanani bamandla afunekayo ukuze kucocwe i-aluminium ibe kumgangatho ophezulu, kunyusa iindleko zeekhoyili ze-aluminium. Ukongeza, i-aluminium enyibilikisiweyo iyahlukana kwaye iye kwindawo yokuqokelelwa. Le ndlela ikwaneemfuno zamandla ezinkulu, ezichaphazela namaxabiso emarike ye-aluminium.
2. Inyathelo lesiBini: Ukuqengqeleka Okushushu
Ukuqengqeleka okushushu yenye yezona ndlela zisetyenziswa kakhulu ukucutha i-aluminium slab. Kwi-hot rolling, isinyithi sitshiswa ngaphezu kwendawo yokuphinda sisetyenziswe ukuze siguqulwe size sibunjwe ngakumbi. Emva koko, esi sitokhwe sesinyithi sidlula kwisibini esinye okanye ngaphezulu see-rolls. Oku kwenziwa ukunciphisa ubukhulu, ukwenza ubukhulu bufane, kunye nokufezekisa umgangatho ofunekayo woomatshini. I-aluminium coil yenziwa ngokucubungula iphepha kwi-1700 degrees Fahrenheit.
Le ndlela inokuvelisa iimilo ezineeparamitha zejiyometri ezifanelekileyo kunye neempawu zezinto ezibonakalayo ngelixa igcina umthamo wesinyithi ungaguquguquki. Le misebenzi ibalulekile ekuveliseni izinto ezigqityiweyo nezigqityiweyo, ezifana neepleyiti kunye namaphepha. Nangona kunjalo, iimveliso ezigqityiweyo eziqengqiweyo zahlukile kwiikhoyili eziqengqiweyo ezibandayo, eziza kuchazwa ngezantsi, kuba azinabukhulu bufanayo ngenxa yenkunkuma encinci phezu komhlaba.
3. Inyathelo Lesithathu: Ukuqengqeleka Okubandayo
Ukuqengqeleka okubandayo kwemigca yesinyithi yindawo eyahlukileyo kwicandelo lokusebenza ngesinyithi. Inkqubo "yokuqengqeleka okubandayo" ibandakanya ukufaka i-aluminium kwiirola kubushushu obuphantsi kunobushushu bayo bokuphinda iguqulwe. Ukucinezela nokucinezela isinyithi kwandisa amandla ayo okuvelisa kunye nobunzima. Ukuqengqeleka okubandayo kwenzeka kubushushu bokuphinda iguqulwe (ubushushu obungaphantsi kobushushu bokuphinda iguqulwe bezinto), kwaye ukuqengqeleka okushushu kwenzeka ngaphezu kobushushu bokuphinda iguqulwe- lo ngumahluko phakathi kokuqengqeleka okushushu kunye nokuqengqeleka okubandayo.
Amashishini amaninzi asebenzisa inkqubo yonyango lwesinyithi eyaziwa ngokuba yi-cold rolling ukuvelisa i-strip kunye ne-sheet metal ene-final gauge efunekayo. Ii-rolls zihlala zifudunyezwa ukunceda i-aluminium isebenze ngakumbi, kwaye i-lubricant isetyenziselwa ukuthintela i-aluminium strip ukuba inamathele kwi-rolls. Ukuze kulungiswe kakuhle ukusebenza, intshukumo ye-rolls kunye nobushushu zinokutshintshwa. I-aluminium strip, esele idlule kwi-hot rolling, kunye nezinye iinkqubo, kubandakanya ukucoca kunye nokunyanga, ipholiswa kubushushu begumbi ngaphambi kokuba ifakwe kumgca we-cold mill rolling kushishino lwe-aluminium. I-aluminium icocwa ngokuyihlamba ngesepha kwaye olu nyango lwenza i-aluminium coil ibe nzima ngokwaneleyo ukumelana ne-cold rolling.
Emva kokuba la manyathelo okulungiselela elungisiwe, imicu idlula ngokuphindaphindiweyo kwiirola, ilahlekelwa bubukhulu ngokuthe ngcembe. Iiplani zelathisi zesinyithi ziyaphazamiseka kwaye zingasebenzi kuyo yonke le nkqubo, nto leyo ephumela kwimveliso yokugqibela eqinileyo neyomeleleyo. Ukuqengqeleka okubandayo kuphakathi kweendlela ezidumileyo zokuqinisa i-aluminiyam kuba kunciphisa ubukhulu be-aluminiyam njengoko icoliwe kwaye ityhalelwa kwiirola. Indlela yokuqengqeleka okubandayo inokunciphisa ubukhulu be-coil ye-aluminiyam ukuya kuthi ga kwi-0.15 mm.
4. Inyathelo Lesine: Ukuncamathisela
Inkqubo yokufunxa lunyango lobushushu olusetyenziswa ikakhulu ukwenza izinto zibe lula kwaye zingabi lukhuni. Ukuncipha kokusasazeka kwesakhiwo sekristale sezinto ezifunxayo kubangela olu tshintsho kubulukhuni kunye nokuguquguquka. Ukuze kuthintelwe ukusilela kokuqhekeka okanye ukwenza izinto zisebenze ngakumbi kwimisebenzi elandelayo, ukufunxa kwenziwa rhoqo emva kokuba izinto ziqiniswe okanye zibanda.
Ngokubuyisela ngokufanelekileyo isakhiwo se-crystalline grain, i-annealing ibuyisela iiplani zokutyibilika kwaye ivumela ukumila ngakumbi kwenxalenye ngaphandle kwamandla agqithisileyo. I-alloy ye-aluminium eqinisiweyo kufuneka ifudunyezwe kubushushu obuthile obuphakathi kwe-570°F kunye ne-770°F kangangexesha elimiselweyo, ukusuka kwimizuzu engamashumi amathathu ukuya kwiiyure ezintathu. Ubungakanani benxalenye e-anneal kunye ne-alloy eyenziwe ngayo zimisela ubushushu kunye neemfuno zexesha, ngokulandelelana.
I-Annealing ikwaqinisa ubukhulu benxalenye, isusa iingxaki ezibangelwa ziingxaki zangaphakathi, kwaye inciphisa uxinzelelo lwangaphakathi olunokuvela, ngokuyinxenye, ngexesha leenkqubo ezifana nokufakelwa okubandayo okanye ukugaywa. Ukongeza, ii-alloys ze-aluminium ezinganyangekiyo ngobushushu nazo zinokugaywa ngempumelelo. Ke ngoko, isetyenziswa rhoqo kwiindawo ze-aluminium ezigayiweyo, ezikhutshiweyo, okanye ezibunjiweyo.
Amandla okwenziwa kwento ethile aphuculwa ngokuyitshixa. Ukucinezela okanye ukugoba izinto eziqinileyo neziqhekekileyo kunokuba nzima ngaphandle kokubangela ukwaphuka. Ukuyitshixa kunceda ekususeni lo mngcipheko. Ukongeza, ukuyitshixa kunokunyusa amandla okusebenza. Ukubhitya kakhulu kwento kunokubangela ukubhitya kakhulu kwesixhobo. Ngokuyitshixa, ubunzima bento bunokuncipha, nto leyo enokunciphisa ukubhitya kwesixhobo. Naziphi na iingcinezelo eziseleyo ziyasuswa ngokuyitshixa. Kudla ngokuba ngcono ukunciphisa iingcinezelo eziseleyo naphi na apho kunokwenzeka kuba zinokukhokelela kwiintanda nakwezinye iingxaki zoomatshini.
5. Inyathelo lesihlanu: Ukunqumla nokusika
Iikhoyili ze-aluminium zinokwenziwa kwiroli enye ende kakhulu eqhubekayo. Nangona kunjalo, ukuze kupakishwe i-coil kwimiqolo emincinci, kufuneka zisikwe. Ukuze kwenziwe lo msebenzi, imiqolo ye-aluminium iqhutywa kwizixhobo zokunqumla apho iiblade ezibukhali kakhulu zenza ukusika okuchanekileyo. Kufuneka amandla amaninzi ukwenza lo msebenzi. Ii-slitters zahlula i-roll ibe ziingceba ezincinci xa amandla asetyenzisiweyo edlula amandla okuxinana kwe-aluminium.
Ukuqala inkqubo yokuqhawula, i-aluminiyam ifakwa kwi-uncoiler. Emva koko, idlula kwiimela ezijikelezayo. Iiblade zibekwe ukuze kufunyanwe umphetho ongcono wokuqhawula, kuthathelwa ingqalelo ububanzi kunye nokususwa okufunekayo. Ukuze izinto eziqhekekileyo zisiwe kwi-recoiler, izinto ezo emva koko zifakwa kwii-separators. Emva koko i-aluminiyam iyahlanganiswa ize isongwe kwi-coil ukulungiselela ukuthunyelwa.
