Izindaba

Njengoba izimoto zikagesi (EVs) zithola ukuduma emhlabeni wonke, isidingo sezinto ezingasindi neziqinile ekukhiqizeni kwazo siyakhula. Ama-alloys e-Aluminium extrusion avele njengoshintsho kumdlaloimboni yezimoto,njengoba zinikeza izinzuzo eziningi ezifana namandla esakhiwo athuthukisiwe, ukunciphisa isisindo, kanye nokusebenza kahle kwamandla. Kulesi sihloko, sizohlola okunye ukusetshenziswa okusha kwama-alloy e-aluminium extrusion kuma-EVs, ikakhulukazi kumathreyi ebhethri, ama-guardrails, namathreyi epuleti lokupholisa.

Ithreyi yebhethri kanye ne-Guardrail

Inkinga eyinhloko yeithreyi yebhethriimpahla, okufanele ibe nokusebenza okuhle kakhulu okuphelele kanye nenani elamukelekayo nelizwakalayo. Ngaphansi kwezimo zamanje, i-aluminiyamu iyona efiseleka kakhulu, iphakeme kunezinhlanganisela ze-plastic matrix (CFRP) zensimbi ne-carbon fibre reinforced plastic matrix (CFRP).

Cishe zonke izinkampani zangempela ezikhiqiza imishini yezimoto zisebenzisa izinsimbi ze-aluminium ukuze zenze amathreyi ebhethri, njenge-BMW, ​​i-Audi Group, i-Volvo, njll. Ngesikhathi esifanayo, ezinye izinkampani zinesithakazelo esikhulu kuthreyi yebhethri ye-skateboard ye-aluminium yonke ye-Tesla eyenziwe nge-aluminium extruded, futhi balandele okufanayo, njengethreyi lemoto yakwaBMW i-i20 EVs, ithreyi lemoto kagesi ye-Audi ye-e-tron, Amaphalethi e I-Daimler's EQ uhla lwezimoto zikagesi nokunye. Amathreyi okuqala akwa-Audi enziwe ngezingxenye ze-aluminium e-die-cast, kodwa manje asethathelwe indawo nge-aluminium ekhishwe. Amathreyi ebhethri ayo ama-BEV nama-PHEV nawo enziwe nge-aluminium extruded.

Kuyaphawuleka ukuthi ezinye izinkampani ezazivame ukwenza ama-pallets ngensimbi manje sezishintshela ku-aluminium. Isibonelo, imoto kagesi ye-Leaf EV ye-Nissan Motor Company yayivame ukusebenzisa insimbi ukwenza amathreyi ebhethri, kodwa yashintshela ku-aluminium ekhishwe ngo-2018; I-Volkswagen ibilokhu inendawo ethambile yamathreyi ebhethri yensimbi, kodwa amathreyi ayo ebhethri yemoto kagesi entsha ye-BEV nawo ahambisana Nalokhu Lo mkhuba uholele ekusetshenzisweni kwe-aluminium extruded; U-AkelMittal wayenqume ukusebenzisa insimbi ephakeme kakhulu yesakhiwo somzimba wemoto ye-Tesla Model 3, kodwa kamuva wathola ukuthi umzimba wesakhiwo sensimbi awuhambisani nokuxhumeka kwethreyi yebhethri ye-aluminium , ngakho-ke yashintshwa yaba umzimba we-aluminium alloy.

Ithreyi ye-slab yokupholisa ye-aluminium emisha

Ngo-2018, i-Constellium's Brunel Advanced Solidification Technology Center yasungula idizayini entsha yethreyi ebizwa ngokuthi “i-aluminium ebandayo”, enamandla okupholisa amaphakethe ebhethri. Ngalo mklamo, asikho isidingo sokuxhunywa kwe-welding ye-friction. Ukuhlolwa kubonise ukuthi ipuleti yokupholisa ixhunywe ngokuqinile futhi ngeke ivuze, futhi ngesikhathi esifanayo, ukuxhumana kulula futhi kuyashesha. Lapho kuhlolwa indlela yokupholisa exubile, kutholwe umphumela wokupholisa owanelisa kakhulu, futhi ukuchezuka kwezinga lokushisa kube ngu-±2 °C kuphela. Ngakho-ke, impilo yesevisi yephakethe yebhethri iyanwetshwa, nokusebenza kokuphepha kuyathuthukiswa. Ezinye izingxenye zethreyi zenziwe nge-aluminium extruded negobile, ngaphandle kokubhoboza noma ukushiselwa, futhi isisindo somklamo omusha wehle ngo-15%.
