Ukubunjwa kwesihlabathi kuyindlela evame kakhuluithusiama-gaskets asetshenziswa ekukhiqizweni kwesihlabathi, anezinzuzo zokuguquguquka okubanzi kanye nokulungiselela ukukhiqiza okulula.Kodwa-ke, ukunemba kobukhulu, ikhwalithi ephezulu, kanye nekhwalithi yangaphakathi yokulingisa okukhiqizwa yile ndlela kusekude ukuhlangabezana nezidingo zezingxenye eziwumshini, futhi inqubo yokukhiqiza iyinkimbinkimbi kakhulu, futhi ukugcwaliseka kokukhiqizwa kwemishini nokuzenzakalelayo kudinga ukutshalwa kwezimali okukhulu.Ekukhiqizeni izingxenye ezithile ezikhethekile kanye nezidingo ezikhethekile zobuchwepheshe Izinkomba zobuchwepheshe nezomnotho ziphansi kakhulu, ngakho-ke ukusetshenziswa kokukhishwa kwesihlabathi ekukhiqizeni i-Foundry kunqunyelwe ngezinga elithile.Ngokungeziwe ekubunjweni kwesihlabathi, ukubunjwa okukhethekile kuye kwakha izinhlobonhlobo zezinye izindlela zokuphonsa ezihlukile ekubunjweni kwesihlabathi ngokushintsha impahla yokuphonsa, indlela yokuthulula, uhlobo lwengxube ye-liquid egcwalisa isikhunta sokuphonsa, noma izimo zokuqina zokubunjwa.Abasebenzi be-Foundry babhekisela kwezinye izindlela zokuphonsa ezihlukile kunqubo yokukhipha isihlabathi njengokuphonsa okukhethekile.Izindlela zokuphonsa ezikhethekile ezijwayelekile embonini yokukhiqiza imishini yilezi:
1. Ukutshala imali.Kuyindlela yokusakaza ukulingwa okungasikiwe noma okusikiwe kancane ngokunemba okuphezulu kobukhulu kanye namanani aphansi okurhabaxa kusetshenziswa amamodeli afusible namagobolondo asebenza kahle kakhulu;ukubunjwa kwensimbi.Kuyindlela yokusebenzisa isikhunta sensimbi ukuze kwandiswe izinga lokupholisa le-casting, ukufeza uhlobo olulodwa lwe-multi-casting, kanye nokuthola ukukhishwa ngesakhiwo se-crystalline esiminyene.
2. Ukukhipha ingcindezi.Kuyindlela yokuthola ama-castings ngokunemba ngokushintsha izimo zokugcwalisa kanye ne-crystallization kanye nokuqina kwama-alloys e-liquid, ukuze ama-alloys e-liquid agcwalise isikhunta ngaphansi kwengcindezi ephezulu kanye nezimo zejubane eliphezulu, futhi enze futhi acwebeze ngaphansi kwezingcindezi eziphezulu, ngaleyo ndlela athole ukukhishwa okunembile;ukukhishwa kwegwebu elilahlekile.Kuyimodeli yepulasitiki enegwebu efana nosayizi nokuma kokuphonswa, eboshwe futhi ehlanganiswe emndenini oyimodeli, exutshwe nge-refractory coating futhi yomisiwe, igqitshwe esihlabathini se-quartz ukuze imodeli yokudlidliza, bese ithululelwa ngensimbi ewuketshezi ngaphansi kwezimo ezithile ukwenza imodeli Indlela yokuhwamuka nokwenza insimbi encibilikisiwe ithathe isikhundla semodeli encibilikisiwe, bese ibumba insimbi epholisa ngemuva kokupholisa isifiso.
3. Ukukhishwa kwengcindezi ephansi.Kuyindlela yokuphonsa phakathi kwamandla adonsela phansi aphonsa ithusi elingenamthofu, elibhekisela enqubweni yokujova insimbi encibilikisiwe esikhunjeni ngaphansi kokusebenza kwamandla adonsela phansi omhlaba, kanye nokuphonsa umfutho.Ngokushintsha izimo zokugcwalisa nokuqiniswa, i-alloy ye-liquid igcwaliswa kancane kancane kusukela phansi kuya phezulu ngaphansi kwesimo sokucindezela okuphansi kanye nesivinini esiphansi, futhi i-crystallized futhi iqiniswe ngokulandelana ukusuka phezulu kuya phansi ngaphansi kwesenzo sokucindezela okuphansi, ukuze kutholwe i-castings ephezulu enesakhiwo esiminyene.
