1. Kuyini ukulingisa.
Imvamisa isho indlela yokwenza imikhiqizo ngezinto ezincibilikisiwe ze-alloy, ukujova ama-alloys angama-liquid kuma-cast enziwe ngaphambilini, ukupholisa, ukuqinisa, nokuthola izikhala nezingxenye zomumo nesisindo esidingekayo.
2. Ukubunjwa kwesikhunta sensimbi.
I-Metal casting, eyaziwa nangokuthi i-hard casting, iyindlela yokuphonsa lapho insimbi ewuketshezi ithululelwa ekubunjweni kwensimbi ukuze kutholwe ukubunjwa.Izibunjwa zokubunjwa zenziwe ngensimbi futhi zingasetshenziswa kabusha izikhathi eziningi (izikhathi ezingamakhulu kuya ezinkulungwaneni).Ukubunjwa kwensimbi manje kungakhiqiza ukubunjwa okulinganiselwe ngesisindo nokuma.Isibonelo, izinsimbi ezisansimbi zingaba kuphela ukubunjwa okunezimo ezilula, isisindo se-castings asikwazi ukuba sikhulu kakhulu, futhi ukushuba kodonga nakho kulinganiselwe, futhi ukushuba kodonga lwama-castings amancane angeke kuphonswe.
3. Ukubunjwa kwesihlabathi.
Ukubunjwa kwesihlabathi kuwubuchwepheshe bokudala bendabuko obusebenzisa isihlabathi njengento eyinhloko yokubumba.Izinto zokubumba ezisetshenziswa ekubunjweni kwesihlabathi zishibhile, zilula ukuphonswa, futhi zingashintshwa ukuze kukhiqizwe ucezu olulodwa, ukukhiqizwa ngobuningi kanye nokukhiqizwa okukhulu kwe-castings.Sekuyisikhathi eside ubuchwepheshe obuyisisekelo bokukhiqiza ukukhiqiza.
4. Amandla adonsela phansi.
Kubhekisela kubuchwepheshe bokuphonsa insimbi encibilikisiwe (ingxubevange yethusi) ngaphansi kwamandla adonsela phansi omhlaba, okwaziwa nangokuthi ukuphonsa kwensimbi.Kuyinqubo yesimanje yokwenza isikhunta esingenalutho ngensimbi ye-alloy ekwazi ukumelana nokushisa.
5. Faka ingxube yethusi.
Impahla eluhlaza esetshenziselwa imikhiqizo yompompi ingxube yethusi ephonsiwe, enezakhiwo ezinhle zokuphonsa, izakhiwo zemishini, ukumelana nokugqwala, kanye nokusakazwa kunokuhleleka okuhle kanye nesakhiwo esihlangene.Ibanga le-alloy yi-ZCuZn40P62 (ZHPb59-1) ngokuya nge-GB/T1176-1987 izimo zenqubo ye-copper alloy, futhi okuqukethwe kwethusi (58.0~63.0)%, okuyindlela ehamba phambili ehamba phambili yokuphonsa.
6. Incazelo emfushane yenqubo yokufaka umpompi.
Okokuqala, emshinini wokudubula ozenzakalelayo we-hot core core, i-sand core ikhiqizwa ukuze ibekwe eceleni, futhi i-alloy yethusi iyancibilika (isithando somlilo sokumelana nemishini yokuncibilikisa).Ngemuva kokuqinisekisa ukuthi ukwakheka kwamakhemikhali we-alloy yethusi kuhlangabezana nezidingo, uthele (imishini yokuthululela ingumshini wokudonsa amandla adonsela phansi ensimbi).Ngemuva kokupholisa nokuqinisa, vula ukukhishwa kwesikhunta bese uhlanza i-outlet.Ngemuva kokuthi wonke amanzi ethusi esithandweni sokumelana athululelwe, zihlole ngokwakho ukuphonsa okupholile.Ithumele esigubhini se-shakeout ukuze sihlanzwe.Isinyathelo esilandelayo ukwelashwa kokushisa kokusakazwa (ukukhipha ukucindezeleka kwe-annealing), inhloso ukuqeda ukucindezeleka kwangaphakathi okukhiqizwa ukusakaza.Faka i-billet emshinini oqhumayo ukuze uthole i-billet ekahle kakhudlwana, futhi uqinisekise ukuthi imbobo yangaphakathi ayixhunywanga nesihlabathi esibumbayo, ama-chips ensimbi noma okunye ukungcola.I-casting billet yayivalwe ngokugcwele, futhi ukuqina komoya kwebhokisi kanye nokuqina komoya kwe-partition kwahlolwa emanzini.Ekugcineni, ukuhlukaniswa nokugcinwa kuhlolwa ngokuhlaziywa kokuhlolwa kwekhwalithi.
