Ukusetyenziswa kunye neempawu ze-graphite sagger crucible

I-Crucible ingasetyenziselwa ukufudumeza okukhulu kwenani elikhulu leekristale. I-Crucible inokwahlulwa ibei-graphite cruciblekwayei-quartz crucible. I-graphite crucible ine-conductivity efanelekileyo ye-thermal kunye nokumelana nokushisa okuphezulu; Kwisicelo sokushisa okuphezulu, i-coefficient yokwandiswa kwe-thermal incinci kakhulu. Inokumelana noxinzelelo oluqinileyo kubushushu obugqithisileyo kunye nokubanda. Iyakwazi ukumelana ne-asidi eqinile kunye ne-alkali. Kufanelekile ukufudumeza iintlobo ezahlukeneyo zolwelo; Ukongeza kwi-chemistry, i-graphite crucibles isetyenziswa ngokubanzi kwi-metallurgy, ukuphosa, oomatshini, imboni yeekhemikhali kunye namanye amasebe; I-graphite crucible yenziwe ngezinto ze-graphite zendalo, ezigcina i-original egqwesileyo yokufudumala yomlilo ekhethekileyo yegraphite. I-graphite crucible isetyenziselwa ukunyibilikisa iintsimbi ezingenayo i-ferrous ezifana nobhedu, i-aluminiyam kunye ne-alloy. Kukho izinto ezingenakubalwa ze-graphite crucible ngokwayo. Apha siza kudwelisa ngokufutshane enye okanye ezimbini kuwe.
1. Ungcoliseko oluncinci, kuba amandla acocekileyo afana nerhasi yendalo okanye irhasi engamanzi angasetyenziswa njengamafutha kunye nongcoliseko oluncinci.
2. Ukusetyenziswa kwamandla aphantsi, kuba i-graphite crucible inesicwangciso esifanelekileyo, isakhiwo esiphezulu kunye nezinto ezintsha. Emva kokuvavanya, ukusetyenziswa kwamandla kuphantsi kunohlobo olufanayo lwesithando somlilo.
I-resistance furnace yokucoceka okuphezulu kwe-graphite crucible isetyenziselwa ukunyibilikisa igolide, isilivere kunye neentsimbi ezinqabileyo.Izibonda zeCeramiczisetyenziswa ikakhulu kwiilabhoratri kunye nokunyibilikiswa kweplatinam, igolide kunye neentsimbi ezinqabileyo. Ngaba i-crucible yegraphite inokuqhutywa kwiqondo lobushushu eliphezulu le-2000 ℃ phantsi kwemeko yomoya? Ngaba iya kubola kwaye i-oxidize ngamandla? Ngaba iya kutshisa isinyithi esityhidiweyo? Eyona nto ibalulekileyo kukuba i-carburizing iyabulala. Kwiimeko eziqhelekileyo, inokufikelela kwii-degrees ze-2000 emoyeni, kodwa iya ku-oxidize ngokukhawuleza. Ingxaki ye-metal carburization kufuneka ibe khona. Ngoku kukho i-anti carburizing ekhethekileyo yokwaleka kwimarike, ekuthiwa inesiphumo esihle.
