1. Khetha ubushushu obuchanekileyo bokuphosa
Ubushushu obuchanekileyo bokuphosa buyinto ebalulekileyo ukuvelisa umgangatho ophezuluimivalo aluminiyam. Iziphene zokubumba ezinje ngeenkozo ezirhabaxa kunye nekristale yentsiba kulula ukwenzeka xa ubushushu buphezulu.
Emva kokucocwa okuziinkozo, iqondo lobushushu lokubunjwa kolwelo lwe-6063 aluminiyam ialloy linokonyuka ngokufanelekileyo, ngokwesiqhelo phakathi kwe-720-740 ℃, kuba:
(1) I-aluminiyam elulwelo iyancangathi emva kokucocwa kweenkozo kunye nokuqiniswa ngokulula kwekristale. (2) Kukho ulwelo-oluqilima kwisigaba esbini kakhulu kwindawo yecrystallization phambi kwebar yealuminiyam ekwenzeni. Ubushushu obuphezulu bokubumba bunommandla omxinwa kakhulu, onceda ekuphunyukeni kwerhasi engabandakanyiyo kumphambili wecrystallization. Kakade ke, iqondo lobushushu alinakuba phezulu kakhulu, iqondo lobushushu eliphezulu kakhulu lokuganga liyakunciphisa ixesha eliluncedo lomcoci wengqolowa kwaye lenze iinkozo zibe nkulu.
2. Xa iimeko zikhona, tshisa ngokugqibeleleyo, yomise inkqubo yokuphosa njengetanki yokuhamba kunye ne-shunt plate ukukhusela ukuphendula kwamanzi kunye ne-aluminium engamanzi ukwenza i-hydrogen absorption.
3. Kwi-aluminium bar forging, zama ukuthintela ukuphazamiseka kunye nokuqengqeleka kwe-aluminium engamanzi, ungasebenzisi nje izixhobo zokuvuselela i-aluminium engamanzi kwi-tank yokuhamba kunye ne-shunt plate, ukwenzela ukuba i-aluminium engamanzi ebusweni befilimu ye-oxide phantsi kokhuseleko lokuhamba okuzinzileyo kwi-crystallization crystallization.
Oku kungenxa yokuba isixhobo solwelo lwe-aluminiyam kunye nokuqengqeleka kolwelo kuya kwenza umphezulu we-aluminiyam oxide ifilimu yahlukane, yenze i-oxidation entsha, kwangaxeshanye, ifilimu ye-oxide ebandakanyekayo kwi-aluminium engamanzi.
Uphando lubonisa ukuba ifilimu ye-oxide inamandla amakhulu e-adsorption, iqulethe i-2% yamanzi, xa ifilimu ye-oxide ibandakanyeka kwi-aluminium engamanzi, amanzi kwifilimu ye-oxide kunye ne-aluminiyam reaction, eyenza i-hydrogen absorption kunye ne-slag.
4. I-aluminium bar ye-aluminium yolwelo lwe-filtration, i-filtration yindlela eluncedo yokususa i-slag ye-nonmetal kulwelo lwe-aluminium, kwi-forging ye-6063 ye-aluminium alloy, ngokuqhelekileyo kunye ne-multi-layer glass fiber cloth filtration okanye i-ceramic filter plate filtration, kungakhathaliseki ukuba luhlobo luni lwendlela yokucoca esetyenziswayo.
Ukuze kuqinisekiswe ukuhluzwa okuqhelekileyo kwe-aluminiyam yolwelo, i-aluminium yolwelo kufuneka isuswe kumphezulu wolwelo phambi kokuhluzwa, kuba umphezulu we-scum kulula ukutyhutyha umnatha wokucoca wento ekrwada, ukuze ukuhluzwa kungaqhutywa ngokuqhelekileyo, indlela elula yokususa umphezulu we-aluminium yolwelo kukuqwalasela ipleyiti ye-slag kwi-tank yolwelo kwi-aluminum.
