Kwimveliso yephepha eliphindwe kabini,ifoyile yealuminiyamukuqengqeleka kwahlulahlulwe ngokweenkqubo ezintathu: ukuqengqeleka okurhabaxa, ukuqengqeleka okuphakathi kunye nokugqiba ukuqengqeleka. Ngokwenjongo yokujonga indlela, inokwahlulwa ngokurhabaxa ukusuka kubunzima bokuphuma. ulwahlulo lulonke kukuba ubukhulu bokuphuma bukhulu kune-0.05mm okanye buyakwazi ukuqengqeleka ngokurhabaxa, kwaye ke ngoko ubukhulu bokuphuma buphakathi kwe-0.013 kunye ne-0.05 yokuqengqeleka okuphakathi. Iphepha eligqityiweyo kunye neemveliso eziphindwe kabini ezinobukhulu be-outlet kodwa i-0.013mm igqityiwe ukuqengqeleka. Iimpawu zokuqengqeleka ze-aluminium icwecwe kunye ne-strip ziyafana. Ulawulo lokutyeba luxhomekeke ikakhulu kumandla okuqengqeleka kunye nasemva koxinzelelo. Ubukhulu bezinga lokusetyenzwa ngokurhabaxa lincinci kakhulu.
(1) ipleyiti yealuminiyam kunye nokuqengqeleka komcu. ukudala aluminiyam strip obhityileyo ikakhulu kuxhomekeke amandla rolling, ukuba imo yolawulo oluzenzekelayo ipleyiti ukutyeba ixhomekeke kwindlela yolawulo umsantsa roll rhoqo kuba umzimba ongundoqo AGC. nokuba okanye hayi utshintsho amandla rolling, lungisa umsantsa roll nangaliphi na ixesha ukuze uhlale ixabiso elithile umsantsa roll, umcu kunye ubukhulu efanayo ifunyenwe. Kwifoyile yokuqengqeleka ukuya ekugqityweni, enkosi kubunzima befoyile ebhityileyo, ukuqengqeleka, ukwanda kwamandla okuqengqeleka, ukwenza imiqulu ye-elastic deformation inzima kakhulu kunokuba iqengqeleke izinto eziqengqelekayo ukubonelela ngoguqulo lweplastiki, i-elastic flattening yomqulu ayinakungahoywa, ukuqengqeleka komdlalo wokucaba kumisela ukuqengqeleka kwefoyile, amandla okuqengqeleka aye kodwa njengendima yelitye, i-aluminium foil eqengqelekayo ngaphandle kokuqengqeleka koxinzelelo, ngoko ke i-foil ye-aluminium ihlala iqengqeleka phantsi koxinzelelo lwe-foil. ubukhulu becala kuxhomekeke kuxinzelelo olulungisiweyo kunye nesantya sokuqengqeleka.
(2) ukupakisha ukuqengqeleka. Kubunzima obuyi-0.012mm (ubukhulu bobukhulu kwaye ke ngoko ububanzi bomqulu womsebenzi) wefoyile yetin, ngenxa yokwaluka okulastiki komqulu, ngendlela enye yokuqengqeleka kunzima kakhulu, ke ngoko ukusetyenziswa kwendlela yokuqengqeleka kabini, oko kukuthi, amaqhekeza amabini efoyile eneoyile embindini, emva koko kunye indlela yokuqengqeleka (ekwabizwa ngokuba kukuqengqeleka). Ukuqengqeleka okulaminethiweyo akukwazi ukuqengqeleka kuphela ifoyile ye-aluminium enokuthi ingaveliswa ngokuqengqeleka kwephepha elinye, kodwa iphinde inciphise ubungakanani bebhanti eyaphukileyo, iphucule imveliso yabasebenzi, kusetyenziswa le nkqubo inokuvelisa i-0.006mm ~ 0.03mm yokukhanya okukodwa kwe-aluminium foil.
(3) Isiphumo sesantya. Ngexesha lokuqengqeleka kwefoyile ye-aluminium, isenzeko sokuba ubukhulu be-foil buyancipha ngokunyuka kwenkqubo yokuqengqeleka ibizwa ngokuba yi-velocity effect. Isizathu sendlela yesiphumo sesantya sihlala siza kufundwa ngakumbi. Iingcaciso zesiphumo sesantya zithathwa ngokubanzi ngolu hlobo lulandelayo:
I-1) Isimo sokungqubuzana phakathi komqulu womsebenzi kwaye ngoko ke izinto eziphathekayo zitshintshile. Ngokunyuka kwesantya sokuhamba, inani legrisi liyenyuka, ngoko ke i-lubrication state phakathi kwe-roll kwaye ngoko ke izinto eziguquguqukayo ziguquka. ngenxa yokuba i-friction coefficient iyancipha, ifilimu yeoli iyajiya kwaye nobukhulu befoyile buyancipha.
2) Utshintsho ngaphakathi kwilitye ngokwalo. Kwii-rolling Mills kunye ne-cylindrical bearings, ngenxa yokuba isantya sokunyuka sinyuka, intamo ye-roller iya kudada ngaphakathi kwi-bearing, ngoko ke ii-roller ezi-2 phantsi kwentsebenziswano ziya kuhamba ngendlela esondelene kakhulu.
3) ukuthanjiswa kokulungiswa kwelaphu xa likhubazekile ngokuqengqeleka. Isantya sokuqengqeleka se-high-speed foil Mill siphezulu kakhulu. Ngokunyuka kwesantya sokuhamba, iqondo lokushisa lommandla we-rolling deformation landa. ngokubala, ubushushu bentsimbi ngaphakathi kwendawo yoguqulo bunokunyuka ukuya kuma-200 ℃, nto leyo ekhumbuza ukubuyisela okuphakathi kwe-annealing, ngaloo ndlela kubangele ukuthomalalisa isenzeko sezinto eziqengqelekayo.
