1. Khetha izinga lokushisa elilungile lokusakaza
Izinga lokushisa elilungile lokuphonsa liphinde libe yisici esibalulekile sokukhiqiza izinga eliphezuluimigoqo ye-aluminium. Ukukhubazeka kokubumba okufana nokusanhlamvu okuqinile kanye nekristalu yophaphe kulula ukwenzeka lapho izinga lokushisa liphezulu.
Ngemuva kokucwenga okusanhlamvu, izinga lokushisa lokubumba lika-6063 aluminium alloy lingakhuphuka ngokufanele, ngokuvamile phakathi kuka-720-740 ℃, ngoba:
(1) I-aluminium ewuketshezi iyanamathela ngemva kokuhluzwa okusanhlamvu nokucwebezela okulula kokuqina. (2) Kukhona indawo eningi kakhulu yezigaba ezimbili eziwuketshezi endaweni ecwebezelayo ngaphambili kwebha ye-aluminium ekufojini. Izinga lokushisa eliphezulu lokufogela linendawo encane kakhulu, evumela ukuphunyuka kwegesi engabandakanyi ngaphambili kwecrystallization. Yiqiniso, izinga lokushisa alikwazi ukuba phezulu kakhulu, izinga lokushisa eliphezulu kakhulu forging kuzonciphisa isikhathi esiwusizo of okusanhlamvu isicwengisisi futhi wenze okusanhlamvu abe kukhulu.
2. Uma izimo zitholakala, shisa kusengaphambili ngokugcwele, yomisa isistimu yokuphonsa njenge-flow tank ne-shunt plate ukuze uvimbele ukusabela kwamanzi ne-aluminium ewuketshezi ukuze kwakhe ukumuncwa kwe-hydrogen.
3. Ekwenziweni kwebha ye-aluminium, zama ukuvimbela isiphithiphithi nokugingqika kwe-aluminium ewuketshezi, ungamane usebenzise okokusebenza ukunyakazisa i-aluminium ewuketshezi ethangini lokugeleza kanye nepuleti le-shunt, ukuze i-aluminium ewuketshezi ebusweni befilimu ye-oxide ngaphansi kokuvikelwa kokugeleza okuzinzile ku-crystallization ye-crystallization.
Lokhu kungenxa yokuthi umshini wokunyakazisa uketshezi lwe-aluminium nokugeleza koketshezi konke kuzokwenza ubuso befilimu ye-aluminium oxide buhlukane, bakhe i-oxidation entsha, ngesikhathi esifanayo, ifilimu ye-oxide ehilelekile ku-aluminium ewuketshezi.
Ucwaningo lubonisa ukuthi ifilimu ye-oxide inamandla anamandla e-adsorption, iqukethe amanzi angu-2%, lapho ifilimu ye-oxide ihileleke ku-aluminium ye-liquid, amanzi efilimu ye-oxide kanye nokusabela kwe-aluminium liquid, okwenza i-hydrogen absorption kanye ne-slag.
4. I-aluminium bar aluminium liquid filtration, ukuhlunga kuyindlela ewusizo yokususa i-slag engeyona eyensimbi oketshezini lwe-aluminium, ekubunjweni kwe-aluminium alloy engu-6063, ngokuvamile ngokuhlunga kwendwangu yengilazi yengilazi eminingi noma ukuhlunga kwepuleti le-ceramic, kungakhathaliseki ukuthi hlobo luni lwendlela yokuhlunga esetshenziswayo.
Ukuze kuqinisekiswe ukuhlungwa okujwayelekile kwe-aluminium ewuketshezi, i-aluminium ewuketshezi kufanele isuswe ku-scum engaphezulu ngaphambi kokuhlunga, ngoba i-scum yangaphezulu kulula ukuyifaka umshini wokuhlunga wezinto ezingavuthiwe, ukuze ukuhlunga kungenzeki ngokujwayelekile, indlela elula yokususa udoti ongaphezulu we-aluminium ewuketshezi ukulungisa ipuleti le-slag ku-aluminium ethangini lokugeleza ukuze kukhishwe i-filtration filtration.
