Kwishishini lokwenziwa kwe-aluminium, ukusetyenziswa kwe-aluminium ceramic launder ukuhambisa i-aluminium enyibilikisiweyo kubalulekile ukuqinisekisa inkqubo yemveliso egudileyo nesebenzayo. I-ceramic launder eyilwe kakuhle nesebenza kakuhle inokuphucula kakhulu umgangatho we-metallurgical we-casting kwaye inegalelo ekongeni amandla.
An i-aluminium ceramic launder ngumjelo osetyenziselwa ukuhambisa i-aluminium enyibilikisiweyo ukusuka esithandweni ukuya kwi-casting mold. Idlala indima ebalulekileyo ekugcineni ukuthembeka kwe-aluminium engamanzi kunye nokuqinisekisa ukuba ifikelela kwi-mold. Uyilo kunye nokwakhiwa kwe-ceramic launder kubalulekile ekufezekiseni ezi njongo.
Enye yezona nzuzo ziphambili zokusebenzisa i-aluminiyam ceramic launder kwinkqubo yokubumba, kukuba iyakwazi ukwehlisa ubushushu be-aluminiyam enyibilikisiweyo. Ngokulawula ulwelo ngokusebenzisa ii-launder ezifakwe i-insulation kakuhle nezifakwe kakuhle, ubushushu bungalawulwa ngcono, kuthintelwe ubushushu obugqithisileyo. Oku kubaluleke kakhulu ekuveliseni ii-castings ezikumgangatho ophezulu ezineempawu ezifunekayo.
Ngaphandle kwezi misebenzi zisisiseko, izixhobo zokuhlamba iimpahla ze-aluminium ceramic ziza ngeendidi ezahlukeneyo ukuze zilungele useto kunye neemfuno ezahlukeneyo ze-foundry. Nokuba i-flow groove ineendidi ezahlukeneyo ezifana ne-DC groove, i-elbow, i-tee, i-cross njalo njalo, imo yesixhobo sokuhlamba iimpahla ze-ceramic inokuba yi-cu.
i-stomized ukuhlangabezana neemfuno ezithile zenkqubo yokubumba. Ukongeza, ulwelo lwe-launder luyilelwe ukuba lube nomphezulu ogudileyo, ongapheleli nje ekuncedeni ukuhamba kakuhle kwe-aluminium enyibilikisiweyo, kodwa unegalelo ekuxhathiseni kwayo ubushushu. Oku kubaluleke kakhulu njengoko ubushushu obungazinzanga bunokubangela imifantu kunye nomonakalo kwi-launder.
Enye into ebalulekileyo ye-aluminium ceramic launder kukuphila kwayo ixesha elide. Izinto ezisetyenzisiweyo zikhethwa ngenxa yokuqina kwayo kunye nokukwazi kwayo ukumelana neemeko ezinzima zendalo ye-foundry. Oku kuqinisekisa ukusebenza kakuhle kwexesha elide kwe-launder, ukunciphisa ixesha lokungasebenzi kunye neendleko zokulungisa.
Ukongeza, izinto zokwambathisa ze-aluminium ceramic launder zenziwe ngokukodwa ukuze zinganamatheli kwi-aluminium. Oku kuthetha ukuba i-aluminium enyibilikisiweyo ayinamatheli kwi-liner, le propati yokunganamatheli ikwanceda ekuphuculeni umgangatho wokubumba.inkqubo yokuphosa ephezulu eshushu,
umaleko obhityileyo weumgubo we-talcum kufuneka isasazwe kwindawo yokuhlamba impahla ngaphambi kokuba iphoswe, akufuneki kubekho ziqwenga zesinyithi eziveziweyo kwaye umjelo apho i-aluminium enyibilikisiweyo idlula khona kufuneka ugcinwe ucocekile kwaye womile, okuvumela ukuhamba okuthe tye nokuqhubekayo.
Ngamafutshane, ukusetyenziswa kwesixhobo sokuhlamba i-aluminium ceramic kwinkqubo yokubumba i-aluminium kubalulekile ekuthuthweni kwe-aluminium enyibilikisiweyo. Ayiphuculi nje kuphela umgangatho we-metallurgical we-castings, kodwa ikwanceda ekongeni amandla. Amandla okunciphisa ubushushu be-aluminium enyibilikisiweyo, ukukhusela izinto ezixutyiweyo zezona zibonelelo ziphambili zokusebenzisa isixhobo sokuhlamba i-aluminium ceramic. Ngokusebenzisa izixhobo eziphambili ezinamandla aphezulu, ukumelana nokugqwala kunye nokumelana nokutshayiswa kobushushu, isixhobo sokuhlamba i-ceramic siqinisekisa ubomi benkonzo ende kwaye sinciphisa ixesha lokungasebenzi. Ngeempawu zaso zokunganamatheli, isixhobo sokuhlamba i-ceramic sikwanceda ekuthinteleni ungcoliseko kwaye siqinisekisa ukuveliswa kwezixhobo zokuhlamba ezikumgangatho ophezulu.
