Umcu we-aluminiyam ubhekisa kwiphepha okanye umcu owenziwe nge-aluminiyam njengeyona nto iphambili ekrwada kwaye ixutywe nezinye izinto zealloyi. Iphepha leAluminiyam okanye umcu yinto ebalulekileyo esisiseko kuphuhliso loqoqosho kwaye isetyenziswa ngokubanzi kwinqwelomoya, i-aerospace, ulwakhiwo, ukushicilela, uthutho, i-elektroniki, ishishini lemichiza, ukutya, amayeza kunye namanye amashishini.
Aluminiyam ingxubevange amaBanga
Uchungechunge 1: 99.00% okanye ngaphezulu kwe-aluminium ecocekileyo yeshishini, i-conductivity elungileyo, ukuchasana nomhlwa, ukusebenza kwe-welding, amandla aphantsi

Inkqubo ebandayo yokuqengqeleka kweAluminiyam
I-Aluminiyam ebandayo yokuqengqeleka ihlukaniswe ngokubanzi ibe ngamacandelo amane: ukunyibilika - ukuqengqeleka okushushu - ukuqengqeleka okubandayo - ukugqiba.
Ukunyibilika kunye nenkqubo yokuvelisa kunye nokuqaliswa kwayo
Injongo yokunyibilika kunye nokuphosa kukuvelisa i-alloy kunye nokwakheka okuhlangabezana neemfuno kunye neqondo eliphezulu lokuhlanjululwa kwe-melted, ngaloo ndlela kudala iimeko ezifanelekileyo zokuphosa i-alloys yeemilo ezahlukeneyo.
Amanyathelo enkqubo yokunyibilika kunye nokuphosa: ukuxubha - ukutya - ukunyibilika - ukuvuselela kunye nokususwa kwe-slag emva kokunyibilika - isampuli yangaphambili yohlalutyo - ukongeza i-alloy ukulungelelanisa ukubunjwa, ukuvuselela - ukucocwa - ukuma - ukuphosa isithando somlilo.
Iiparamitha ezininzi eziphambili zenkqubo yokunyibilika kunye nokuphosa
Ngexesha lokunyibilikisa, ubushushu beziko ngokuqhelekileyo bubekwe kwi-1050°C. Ngethuba lenkqubo, ubushushu bezinto eziphathekayo kufuneka bubekwe esweni ukulawula ubushushu bentsimbi ukuba bungabi ngaphezu kwe-770 ° C.
Umsebenzi wokususwa kwe-slag wenziwa malunga ne-735 ℃, ehambelana nokuhlukana kwe-slag kunye nolwelo.
Ukucokisa ngokubanzi kusebenzisa indlela yesibini yokusulungekisa, eyokuqala yongeza i-ejenti yokucoca eqinileyo, kwaye ukucokisa okwesibini kusebenzisa indlela yokusulungekisa igesi.
Ngokuqhelekileyo, kufuneka iphoswe ngexesha le-30min ~ 1h emva kokuba isithando somlilo sishiywe ukuba sime, ngaphandle koko kufuneka sihlanjululwe kwakhona.
Ngethuba lenkqubo yokuphosa, ucingo lwe-AI-Ti-B kufuneka ludityaniswe ngokuqhubekayo ukuze lucokise iinkozo.
Inkqubo yokuvelisa eshushu kunye nokuqaliswa kwayo
1. Ukuqengqeleka okushushu ngokuqhelekileyo kubhekisa ekuqengqelekeni ngaphezulu kobushushu bentsimbi.
2. Ngethuba lokutshisa okutshisayo, isinyithi siqhuba zombini iinkqubo zokuqina kunye nokuthambisa. Ngenxa yempembelelo yezinga lokuguqulwa, nje ukuba iinkqubo zokubuyisela kunye ne-recrystallization zingenziwanga ngexesha, kuya kuba neqondo elithile lomsebenzi wokuqina.
3. I-recrystallization yensimbi emva kokutshisa okutshisayo ayiphelelanga, oko kukuthi, isakhiwo esihlaziyiweyo kunye nesakhiwo esikhubazekileyo sihlala kunye.
4. I-Hot rolling inokuphucula ukusebenza kwesinyithi kunye ne-alloys kunye nokunciphisa okanye ukuphelisa iziphene zokuphosa.
Ukuhamba kwenkqubo yekhoyili eqengqelekayo
Ukuhamba kwenkqubo ye-coil edibeneyo eshushu ngokuqhelekileyo: i-ingot casting - i-milling surface, i-milling edge - ukufudumeza - i-hot rolling (i-opening rolling) - i-hot finishing rolling (i-coil rolling) - i-coil yokukhulula.
Umphezulu wokugaya kukuququzelela ukusetyenzwa okushushu. Ngenxa yesikali se-oxide kunye nokuphosa isakhiwo esihle kumphezulu, ukuqhubekeka okulandelayo kudla ngokuba neziphene ezinje ngeendawo eziqhekekileyo kunye nomgangatho ombi womphezulu.
Injongo yokufudumeza kukuququzelela inkqubo yokugoqa eshushu elandelayo kunye nokubonelela ngesakhiwo esithambileyo. Ubushushu bobushushu buphakathi kwe-470℃ kunye ne-520℃, kwaye ixesha lokufudumeza yi-10 ~ 15h, hayi ngaphezulu kwe-35h, kungenjalo inokutshiswa ngokugqithisileyo kunye nesakhiwo esirhabaxa siya kuvela.
Imiba yemveliso eqengqelekayo eshushu efuna ukuhoywa
Iipasile zokuqengqeleka ze-alloy eqinile zahlukile kwezo ze-alloy ethambileyo. Iipasile zokuqengqeleka ze-alloy eqinile zingaphezulu kwezo ze-alloy ethambileyo, ukusuka kwi-15 ukuya kwi-20 yokupasa.
Ubushushu bokugqibela bokuqengqeleka bufuna ukulawulwa ngokungqongqo, njengoko kuchaphazela ngokuthe ngqo ukusetyenzwa okulandelayo kunye neempawu ezibonakalayo kunye neekhemikhali zemveliso egqityiweyo.
I-alloy ngokubanzi ifuna i-rolling edge ngexesha lenkqubo yemveliso.
Amasango entloko kunye nomsila kufuneka anqunyulwe.
I-emulsion yinkqubo yamanzi kwi-oyile, apho amanzi adlala indima yokupholisa kwaye ioli idlala indima yokuthambisa. Kufuneka igcinwe kwindawo emalunga nama-65°C unyaka wonke.
Isantya sokuqengqeleka esishushu sijikeleze i-200m/min.
Inkqubo yokuphosa kunye nokuqengqeleka
Ubushushu bokuphosa kunye nokuqengqeleka buphakathi kwe-680℃-700℃, kokukhona kusezantsi kungcono. Umgca wokusa kunye nowokuqengqeleka ozinzileyo uya kumisa kanye ngenyanga okanye ngaphezulu ukumisa kwakhona ipleyiti. Ngethuba lenkqubo yokuvelisa, inqanaba le-liquid kwibhokisi elingaphambili lifuna ukulawulwa ngokungqongqo ukukhusela inqanaba eliphantsi lolwelo.
I-Lubrication iqhutyelwa ngokusebenzisa i-C powder ukusuka ekutshisweni okungaphelelanga kwerhasi yamalahle, ekwasinye sezizathu zokuba umphezulu we-cast and rolled material umdaka.
Isantya sokuvelisa ngokubanzi siphakathi kwe-1.5m/min-2.5m/min.
Umgangatho womphezulu weemveliso eziveliswa ngokusaswa kunye nokuqengqeleka uphantsi ngokubanzi kwaye awunakukwazi ukuhlangabezana neemfuno zeemveliso ezinomzimba okhethekileyo kunye neekhemikhali.
Imveliso eqengqelekayo ebandayo
1. I-Cold rolling ibhekisela kwindlela yokuvelisa i-rolling ngaphantsi kweqondo lokushisa lokuphinda lihlanjululwe.
2. I-Dynamic recrystallization ayenzeki ngexesha lenkqubo yokuqengqeleka, iqondo lokushisa liphakama kwiqondo lokushisa lokubuyisela kakhulu, kwaye ukugoqa okubandayo kubonakala kwimeko yobunzima bomsebenzi kunye nesantya esiphezulu sobunzima bomsebenzi.
3. I-cold-rolled strip ine-high dimensional ichanekile, umgangatho omhle womphezulu, intlangano efanayo kunye nokusebenza, kwaye inokuveliswa kumazwe ahlukeneyo ngonyango lokushisa.
4. I-Cold rolling inokuvelisa imichilo emincinci, kodwa nayo ineengxaki zokusebenzisa amandla okuguqula amandla kunye nokupasa okuninzi.
Intshayelelo emfutshane kwiNkqubo ePhambili yeeParameters zeCold Rolling Mill

Intshayelelo yokugqiba inkqubo yokuvelisa
1. Ukugqiba kuyindlela yokucubungula ukwenza iphepha elipholileyo lihlangabezane neemfuno zomthengi, okanye ukuququzelela ukuqhutyelwa kwemveliso elandelayo.
2. Izixhobo zokugqiba zingalungisa iziphene eziveliswe ngexesha lokutshisa okutshisa kunye nenkqubo yokuvelisa ebandayo, njengamaphethelo aqhekekileyo, umxholo we-oyile, i-plate shape embi, uxinzelelo oluseleyo, njl njl. Kuyimfuneko ukuba kuqinisekiswe ukuba akukho ziphene zingeniswa ngexesha lenkqubo yokuvelisa.
3. Kukho izixhobo ezahlukeneyo zokugqiba, ngokukodwa kubandakanywa ukunqumla, ukucheba i-longitudinal, ukulungiswa kokwelula kunye nokugoba, isithando somlilo, umatshini wokuqhawula, njl.
