Ukubunjwa kwesihlabathi kuyindlela evamile kakhulu yokuphonsa, okuyindlela yokuphonsa lapho isihlabathi sisetshenziswa njengento eyinhloko yokubumba ukuze kulungiswe isikhunta. Insimbi, insimbi kanye nokusakazwa okuningi kwe-alloy non-ferrous kungatholakala ngokusakazwa kwesihlabathi. Ngenxa yokuthi izinto zokubumba ezisetshenziswa ekubunjweni kwesihlabathi ishibhile futhi kulula ukuzithola, futhi isikhunta sokuphonsa kulula ukwenza, singashintshwa ukuze sikhiqize ucezu olulodwa, ukukhiqizwa kwe-batch kanye nokukhiqizwa okukhulu kwe-castings. Kube yinqubo eyisisekelo ekukhiqizeni ukusakaza isikhathi eside.
Inqubo eyisisekelo yenqubo yokukhipha isihlabathi ngokuyinhloko ihlanganisa izigaba ezilandelayo: ukwenza isikhunta, ukuhlanganisa isihlabathi, ukubumba, ukuncibilika, ukuthululwa, nokuhlanza.
1. Isiteji sokukhiqiza isikhunta: Yenza isikhunta ngokuvumelana nezidingo zemidwebo. Ngokuvamile, isikhunta sokhuni singasetshenziselwa ukukhiqiza ucezu olulodwa, isikhunta sepulasitiki kanye nezibunjwa zensimbi zingenziwa ukuze kukhiqizwe ngobuningi, futhi izifanekiso zingenziwa ukuze kukhishwe izikali ezinkulu.
2. Isiteji sokuxuba isihlabathi: Ngokwezidingo zokwenziwa kwesikhunta sesihlabathi kanye nezinhlobo zokubunjwa, isihlabathi sokubumba esifanelekayo silungiselelwa ukubunjwa/ukwenziwa komgogodla.
3. Isiteji sokumodela/sokwenza ingqikithi: okuhlanganisa ukumodela (ukwenza umgodi wokubunjwa ngesihlabathi esibumbayo), ukwakheka kwengqikithi (ukwenza umumo wangaphakathi wokubunjwa), nokumadanisa isikhunta (ukufaka umgogodla wesihlabathi esikhaleni kanye nokuvala indawo engaphezulu. namabhokisi esihlabathi aphansi) . Ukubumba kuyisixhumanisi esiyinhloko ekulingiseni.
4. Isiteji sokuncibilikisa: Lungiselela ukwakheka kwamakhemikhali ngokuvumelana nokwakheka kwensimbi edingekayo, khetha isithando somlilo esincibilikayo esifanelekayo ukuze uncibilikise ingxubevange, bese wenza uketshezi lwensimbi oluwuketshezi olufanelekile (okuhlanganisa ukwakheka okufanelekayo kanye nezinga lokushisa elifanelekayo).
5. Isiteji sokuthela: jova insimbi encibilikisiwe efanelekayo ebhokisini lesihlabathi elifakwe isikhunta. Naka ijubane lokuthulula lapho uthela, ukuze insimbi encibilikisiwe igcwalise yonke indawo. Isiteji sokuthulula siyingozi kakhulu, ngakho-ke ukunakwa okukhethekile kufanele kukhokhwe ekuphepheni.
6. Isiteji sokuhlanza: Inhloso yokuhlanza ukukhipha isihlabathi, ukugaya kanye nensimbi eyeqile ekubunjweni, kanye nokwenza ngcono ukubukeka kwendawo yokubunjwa. Ngemva kokuba insimbi encibilikisiwe iqiniswe ngemva kokuthululwa, isihlabathi esibunjwayo siyasuswa, i-sprue nezinye izesekeli ziyasuswa, bese kwakhiwa ukubunjwa okudingekayo, futhi ekugcineni amaphutha ayo kanye nekhwalithi iyonke iyahlolwa.
Isihlabathi se-Ceramic sinezinzuzo zokumelana nokushisa okuphezulu, akukho ukuphuka, akukho uthuli, ukuma kwe-spherical, ukuphakama komoya okuphezulu, ukusebenza kahle kokugcwalisa, akukho bungozi bothuli lwe-silica, njll. Kuyisihlabathi sokuphonsa esiluhlaza futhi esivumelana nemvelo. Ifanele ukukhishwa kwesihlabathi (isihlabathi sesikhunta, isihlabathi esiyinhloko), ukukhishwa kwendlela ye-V, ukukhishwa kwegwebu elilahlekile (isihlabathi sokugcwalisa), ukumboza (i-ceramic sand powder) nezinye izinqubo zokuphonsa. Isetshenziswa ezinjinini zezimoto kanye nezingxenye zezimoto, insimbi enkulu ekhonjiwe, insimbi engagqwali, nezinsimbi, ama-non-ferrous alloy castings neminye imikhakha isetshenziswa kabanzi, eyaziwa ngokuthi isihlabathi sokuphonsa esiluhlaza nesihambisana nemvelo.
