Ukusetshenziswa kanye nezici ze-graphite sagger crucible

I-Crucible ingasetshenziswa ekufudumaleni okukhulu kwenani elikhulu lamakristalu. I-Crucible ingahlukaniswa ibeisitsha sokubethela se-graphitefuthii-quartz crucible. I-Graphite crucible inomoya omuhle wokushisa kanye nokumelana nokushisa okuphezulu; Ekusetshenzisweni kokushisa okuphezulu, i-coefficient yokwanda kokushisa incane kakhulu. Inokumelana okunamandla kokushisa nokubanda okukhulu. Imelana ne-asidi enamandla kanye ne-alkali. Ifanelekela ukufudumeza izinhlobo ezahlukene zoketshezi; Ngaphezu kwe-chemistry, i-graphite crucibles isetshenziswa kabanzi ekusetshenzisweni kwensimbi, ekubunjweni, emishinini, embonini yamakhemikhali nakweminye iminyango; I-graphite crucible yenziwe ngezinto zemvelo ze-graphite, ezigcina ukushisa okukhethekile komlilo kwe-graphite. I-graphite crucible isetshenziswa kakhulu ekuncibilikiseni izinsimbi ezingezona i-ferrous njengethusi, i-aluminium kanye ne-alloy. Kunezici ezingenakubalwa ze-graphite crucible ngokwayo. Lapha sizobala kafushane eyodwa noma ezimbili zakho.
1. Ukungcola okuncane, ngoba amandla ahlanzekile njengegesi yemvelo noma igesi encibilikisiwe angasetshenziswa njengophethiloli kanye nokungcola okuncane.
2. Ukusetshenziswa kwamandla aphansi, ngoba i-graphite crucible inohlelo olufanele, isakhiwo esithuthukisiwe kanye nezinto ezintsha. Ngemva kokuhlola, ukusetshenziswa kwamandla kuphansi kunokwesithando sohlobo olufanayo.
I-graphite crucible evikelayo enesithando somlilo esihlanzekile kakhulu isetshenziswa kakhulu ekuncibilikiseni igolide, isiliva kanye nezinsimbi ezingavamile.Izitsha zobumbaZisetshenziswa kakhulu emalabhorethri nasekuncibilikiseni iplatinum, igolide kanye nezinsimbi ezingavamile. Ingabe i-graphite crucible ingasetshenziswa ekushiseni okuphezulu okungu-2000 ℃ ngaphansi kwesimo somoya? Ingabe izobola futhi i-oxidize ngamandla? Ingabe izoyi-carburize insimbi encibilikisiwe? Into ebaluleke kakhulu ukuthi i-carburize iyabulala. Ngaphansi kwezimo ezijwayelekile, ingafinyelela kuma-degree angu-2000 emoyeni, kodwa izoyi-oxidize ngokushesha. Inkinga ye-carburize yensimbi kumele ibe khona. Manje kukhona i-anti carburize ekhethekile emakethe, okukhulunywa ngayo ukuthi inomphumela omuhle.
