Ipuleti le-aluminium elingu-5xxx lingelama-alloys asetshenziswa kakhulu. Isici esiyinhloko se-alloying yi-magnesium kanti okuqukethwe kwe-magnesium kuphakathi kuka-3-5%. Ingabuye ibizwe nge-aluminium-magnesium alloy. 5083 cast aluminium plate ingeye-hot rolled aluminium plate. Ukugoqa okushisayo kwenza ishidi le-aluminium engu-5083 libe nokumelana nokugqwala okuphezulu nokumelana nokukhathala.

I-hot rolling izongena ngaphezu kwe-90% ye-thermal deformation. Phakathi nenqubo yokuguqulwa kwepulasitiki enkulu, isakhiwo sangaphakathi siye sathola ukubuyiswa okuningi kanye nokuvuselelwa kabusha, futhi okusanhlamvu okuqinile esimweni sokuphonsa kuphukile futhi ama-micro-cracks ayaphulukiswa, ngakho-ke ukukhubazeka kokuphonsa kungathuthukiswa kakhulu.

Izinhlobo zemikhiqizo egoqiwe eshisayo

1. Amapuleti awugqinsi aginqike ngokushisayo: Kubhekiselwa kumapuleti e-aluminium anogqinsi olungekho ngaphansi kuka-7.0 mm. Izinhlobo eziyinhloko zingamapuleti ashisayo, amapuleti ane-annealed, acinywe noma acinywe amapuleti angaphambi kokwelulelwa. Inqubo yendabuko yile: i-ingot homogenization - indawo yokugaya - ukushisa - ukugoqa okushisayo- ukusika kusayizi- ukuqondisa.

2. Ikhoyili ye-aluminiyamu egoqwe ngokushisayo: Amashidi e-aluminium ne-aluminium alloy nemicu enogqinsi olungaphansi kuka-7.0 ngokuvamile akhiqizwa ngamakhoyili agoqwe ashisayo.

Inqubo yokugoqa eshisayo yepuleti le-aluminium engu-5083

1. Ukulungiselela ngaphambi kokuginqika okushisayo kufaka phakathi ukuhlolwa kwekhwalithi ye-ingot, ukucwiliswa emanzini, ukusaha, ukugaya, ukunamathela kwe-aluminium, nokufudumeza.

2. Ngesikhathi sokukhipha kancane kancane, izinga lokupholisa liphezulu kakhulu, inqubo yokusabalalisa esigabeni esiqinile inzima, futhi ingot ilula inesakhiwo esingalingani, njengokuhlukaniswa kwe-intragranular.

3. Uma kuneziphambeko ezifana nokuhlukaniswa, ukufakwa kwe-slag, ukukhwabanisa, nokuqhekeka ebusweni be-ingot, ukugaya kufanele kwenziwe. Kuyisici esibalulekile ukuqinisekisa ikhwalithi enhle yendawo yomkhiqizo oqediwe.

4. I-hot rolling ye-aluminium alloy ingots iwukunikeza amabhilidi okugoqa okubandayo, noma ukukhiqiza ngokuqondile amapuleti awugqinsi esimweni esishisayo esigoqekayo.
