Mundima yemaindasitiri maitiro,graphitegraphite silicon carbide crucible tamba basa rakakosha mukushandisa kwakasiyana siyana senge metallurgy, foundry uye makemikari marabhoritari. Kuti uve nechokwadi chekushanda kwakakwana uye hupenyu hurefu hwezvishandiso izvi zvakakosha, chirongwa chakazara chekuchengetedza chinofanira kuteverwa.
Chokutanga uye chakakosha, kuchengetwa kwegraphitegraphite silicon carbide crucible zvinoda kunyatsotarisirwa. Izvigraphite silicon carbide crucible inofanira kuchengetedzwa munzvimbo yakaoma uye yakadzivirirwa kubva pakunyorova nguva dzose. Inokurudzirwa kuti uzvichengete muhuni yakaoma kana yehuni kuti upe humwe hutete hwekudzivirira. Fragility inotsanangura hunhu hwegraphitegraphite silicon carbide crucible uye saka inofanira kubatwa nekuchenjerera kwakanyanya panguva yekufambisa. Chero chimiro chekukanganisa kana kuzununguka kunofanirwa kudzivirirwa zvakanyanya kudzivirira kukanganisa.
Iyo crucible inofanira kunge ichipisa zvishoma nezvishoma kusvika ku500°C usati washandisa. Paunenge uchiwedzera kupisa zvinhu, zvakakosha kufunga nezvekugona kweiyo crucible uye kuve nechokwadi kuti mari yakawedzerwa iri pakati pechetatu nezvikamu zviviri kubva muzvitatu zvehuwandu hwayo. Pamusoro pezvo, maturusi uye mabhanhire anoshandiswa kuburitsa anofanirwa kuve akagadziridzwa zvinoenderana nechimiro checrucible uye ave neakakodzera clamping simba kudzivirira chero kukuvara.
Munguva yekuwedzera zvinhu, zvakakosha kudzora huwandu hwezvinhu zvakanyungudutswa mucrucible uye kudzivirira kuwedzeredza kana kuwedzera-kusimbisa kudzivirira kuwedzera. Paunenge uchibvisa slag uye coke kubva mukati uye kunze kwemadziro e-crucible, zvinokurudzirwa kurova zvishoma kudzivirira kukanganisa. Kuiswa kwakakodzera mukati mechoto kunokosha zvakare, ne crucible inochengetwa panzvimbo yakakodzera kubva pamadziro echoto uye yakaiswa pakati kuti iite zvakakwana.
Kuenderera mberi nekushandisa kunobatsira crucible kuratidza kuita kwayo kwepamusoro. Nekudaro, huwandu hwakawandisa hwekupisa accelerator uye zvinowedzera zvinofanirwa kudzivirirwa sezvo zvichigona kuderedza zvakanyanya hupenyu hwesevhisi yecrucible. Kuti uwedzere hupenyu hwebasa re crucible, zvinokurudzirwa kutenderera kamwechete pavhiki panguva yekushandiswa.
Pamusoro pezvo, zvakakosha kuti udzivise jekiseni rakananga remwoto wakasimba weoxidizing pamativi uye pazasi pe crucible sezvo izvi zvichigona kukuvadza. Nekuomerera kune aya ekugadzirisa nhungamiro, zvivakwa zveindasitiri zvinogona kuve nechokwadi chekugara kwenguva refu uye kugona kwegraphite yavographite silicon carbide crucible, pakupedzisira inobatsira mukushanda kwakanaka kwemaitiro akasiyana-siyana uye kushandiswa.
