Sechishandiso chakakosha mumaindasitiri akadai sekunyungudutsa simbi uye kumwe kupisa kwakanyanya-tembiricha, magirafu crucibles anoita basa rakakosha mukuve nekupisa simbi dzakasiyana-siyana uye alloys. Nekudaro, hupenyu hwavo hwesevhisi hwaive hushoma, izvo zvinogona kunetsa uye zvichikonzera kuwedzera mari yevashandisi. Muchikamu chino, tichaongorora nzira dzakafanana dzekuwedzera hupenyu hwema graphite crucibles uye kuwedzera kusimba kwavo.
Graphite crucibles anoshandiswa zvakanyanya kunyungudusa uye kukanda maitiro, nekuda kweakanyanya kupisa conductivity, corrosion resistance uye refractory properties. Nekudaro, hupenyu hwavo hurefu hunoenderana nezvinhu zvakati wandei, senge mhando yezvigadzirwa, maitiro ekugadzira, mamiriro ekushanda, uye maitiro ekugadzirisa. Naizvozvo, zvakakosha kuti usarudze emhando yepamusoro crucibles kubva kune vanovimbika vatengesi uye uteedzere nhungamiro inokurudzirwa yekushandiswa kwavo uye kutarisira.
Chimwe chinhu chakakosha chinokanganisa hupenyu hwema graphite crucibles kudziya uye kutonhora maitiro. Kungoerekana kwachinja tembiricha, inozivikanwawo seyekuvhundutsa kwemafuta, inogona kutungamira mukutsemuka, spalling, kana deformation yemacrucibles, pakupedzisira ichidzikisa hupenyu hwavo hurefu uye kushanda. Kuti udzivise nyaya idzi, zvinokurudzirwa kuti zvishoma nezvishoma uye zvakafanana preheat macrucibles usati wawedzera simbi kana alloys uye wozozvitonhodza zvishoma nezvishoma mushure mekunge maitiro apera.
Chimwe chinhu chakakosha kufunga, inova mhando yesimbi kana alloy iri kugadziriswa. Mamwe masimbi, akadai sesimbi, nickel uye cobalt, anogona kubatwa negraphite pakupisa kwakanyanya uye kuumba carbides, iyo inogona kukurumidza kupera uye kubvaruka kweiyo crucibles. Kuti udzivise izvi, zvinokurudzirwa kushandisa mabhanhire ekudzivirira kana liner pama crucibles kana kusarudza akasarudzika magirafu mamakisi anopokana nekuita kwakadaro.
Uye zvakare, kuchengetedza kwakaringana uye kucheneswa kwema crucibles kwakakosha zvakare mukuwedzera hupenyu hwavo uye kudzivirira kusvibiswa kwesimbi kana alloys. Inokurudzirwa kubvisa, kutonhora, uye kuchenesa crucibles mushure mekushandisa kwega kwega uchishandisa maturusi akakodzera uye makemikari kubvisa chero zvakasara kana tsvina. Kuchengetedzwa kwakaringana kwema crucibles munzvimbo yakaoma uye yakachengetedzeka kwakakoshawo kudzivirira kukuvadzwa kwemuviri kana kunwa hunyoro.
Kupfupisa, kuwedzera hupenyu hwemagraphite crucibles kunoda kuomerera kune kwakaringana maitiro uye kudzivirira. Izvi zvinosanganisira kusarudza macrucibles emhando yepamusoro, kuabata nehanya, kudzora kupisa nekutonhodza maitiro, kuadzivirira kubva kusimbi dzinoshanda, uye kugara achizvichengeta. Nekuita kudaro, vashandisi vanogona kuchengetedza nguva, mari, uye zviwanikwa uku vachiona kunoenderana uye kwakavimbika crucible kuita.
