I-aluminium billet lukhetho oludumileyo kumashishini ahlukeneyo njengoko edlala indima ebalulekileyo kwiinkalo ezahlukeneyo ezifana neemoto, i-aerospace kunye nokwakhiwa ngenxa yobunzima bazo, amandla aphezulu kunye ne-thermal conductivity egqwesileyo.Nangona kunjalo, inkqubo ye-aluminium billet casting idinga izixhobo ezikhethekileyo kunye nezixhobo zokuqinisekisa umgangatho ophezulu wemveliso.Icandelo elibalulekileyo sisihlamba sokuhambisa.
Iukuhambisa impahlayinxalenye ye-aluminiyam ye-billet yokuphosa inkqubo, esetyenziselwa ukuphosa ipleyiti kwaye yenzelweumatshini wokuphosa phezulu oshushui-aluminiyam kunye ne-alloys ye-aluminium.Ulwelo aluminiyam luphuma kwiezikokwaye udlula kwi-aukuhlamba ngeceramic kwaye emva kwe-aibhokisi yokucocakwindawo yokuhambisa iimpahla.Inoxanduva lokuhamba kakuhle kunye nokusebenza kakuhle kwe-aluminium etyhidiweyo kwi-mold, iqinisekisa ukuchaneka kunye nokunyaniseka kwemveliso yokugqibela.
Ukuze kuhlangatyezwane neemfuno ezifunekayo zenkqubo yokuphosa i-billet ye-aluminium, i-launder yokusabalalisa yenziwe nge-aluminium-silicate fiber kunye ne-ceramic composite.Olu kudibanisa lubonelela ngokugqwesa kwe-thermal insulation, iqinisekisa ukulahleka kobushushu obuncinci ngexesha lenkqubo yokuphosa.Ukufakwa kakuhle kwe-thermal kunceda kwakhona ukugcina ubushushu obuqhubekayo kwi-mold, okuphucula umgangatho wokuphosa kunye nokunciphisa iziphene.Ukongeza, i-launder yokuhambisa inokumelana nobushushu obugqwesileyo, ibenza bakwazi ukumelana nobushushu obuphezulu bolwelo lwe-aluminium.Oku kumelana nokushisa okuphezulu kuqinisekisa ukuhlala kunye nobomi obude be-launder yokusabalalisa, okwenza kube yindleko-esebenzayo yokukhetha abavelisi bokuphosa.
Olunye uphawu olubalulekileyo lokuhambisa impahla yi-aluminiyam engeyiyo intonga.I-aluminium etyhidiweyo ivame ukunamathela kumphezulu wezinto eziphathekayo, ekhokelela ekubunjweni kwe-slag kunye nokunciphisa ukusebenza kakuhle.Ubume obungeyona intonga ye-launder yokusabalalisa kunokuthintela ukwakhiwa kwe-slag, ukuqinisekisa ukuhamba kakuhle kwe-aluminium liquid ngexesha lenkqubo yokuphosa kunye nokwandisa ukonga ixesha.IdistriI-buion launder nayo yomelele kwaye iyamelana nokukhuhla kwaye inokumelana nokuhamba kwe-aluminiyam ngaphandle kokuguqulwa okanye umonakalo.La mandla aphezulu akaqinisekisi kuphela ukuthembeka kwemveliso ephosiweyo, kodwa igcina iindleko zabakhiqizi ngokunciphisa imfuno yokutshintshwa rhoqo.
Ukongeza kwiipropathi ezigqwesileyo zezinto eziphathekayo, i-launder yokuhambisa inika ukuxhathisa okuphezulu kwe-corrosion.Ubume be-aluminiyam etyhidiweyo ebolileyo bunokuthoba ukusebenza kwezixhobo, ukunciphisa umgangatho wemveliso yokugqibela.Nangona kunjalo, ukuxhathisa kwe-corrosion ye-launder yokuhambisa iqinisekisa ukucoceka kunye nokunyaniseka kolwelo lwe-aluminium kuyo yonke inkqubo yokuphosa.
Ukongeza, iimpahla zokuhambisa iimpahla zifumaneka ngobungakanani ukusuka ku-3 ″ ukuya ku-9 ″, 10 ″, 12 ″, 14 ″, 16 ″, 18 ″, 20 ″, kodwa abavelisi banakho ukwenza ngokwesiko ubungakanani bokuhambisa iimpahla ukuqinisekisa ukuba kufanelekile nakuphi na. ukufaka isicelo.Oku kuguquguquka kuvumela abathengi ukuba bahlangabezane neemfuno ezahlukeneyo zemveliso kunye nokwandisa imveliso.
Ukuqinisekisa umgangatho we-launder yokusabalalisa, i-zhelu isebenzisa iindlela eziphuculweyo zokuvelisa ezifana ne-vacuum casting.Oku kuqinisekisa ngcono ukusebenza kwemveliso kunye nokuphucula umgangatho wemveliso yokugqibela.Ukudityaniswa kweendlela eziphambili zokuvelisa kunye nezixhobo ezikumgangatho ophezulu zenza ukuhanjiswa kwezinto zokuhambisa kube yinxalenye yenkqubo yokuphosa i-aluminium.
Isishwankathelo, ukusetyenziswa kwe-launder yokuhambisa kwi-aluminium casting kubalulekile ukuqinisekisa ukuveliswa kwe-billet ephezulu ye-aluminium.Ukugqunywa kwayo kakuhle kwe-thermal, ukumelana nobushushu obuphezulu, iipropathi ze-aluminiyam ezingabambekiyo, amandla aphezulu, ubomi benkonzo ende, ukuxhathisa ukukhuhlwa kunye nokugqwala kolwelo lwe-aluminiyam kuyenza ibe lolona khetho lubalaseleyo kubenzi beziseko.I-launder yokuhambisa iphinda ixhamle kumandla ayo okulungelelaniswa kwiimfuno ezithile, iyenze ibe isisombululo esiguquguqukayo kunye neendleko ezifanelekileyo.Ngobuchwepheshe obuphezulu bokuvelisa kunye neempahla eziphezulu zezinto eziphathekayo, ukuhanjiswa kwempahla kuye kwaba yinxalenye ebalulekileyo yenkqubo yokuphosa i-aluminium billet, ukuqhuba kakuhle kunye nomgangatho wemveliso kwishishini le-aluminium.
