Isicelo kanye nezici ze-graphite sagger crucible

I-Crucible ingasetshenziselwa ukushisa okukhulu kwenani elikhulu lamakristalu. I-Crucible ingahlukaniswa ibei-graphite cruciblefuthii-quartz crucible. I-graphite crucible ine-conductivity enhle yokushisa kanye nokumelana nokushisa okuphezulu; Ekusetshenzisweni kwezinga lokushisa eliphezulu, i-coefficient yokwandisa okushisayo incane kakhulu. Inokumelana okuqinile nokushisa okukhulu nokubanda. Iyakwazi ukumelana ne-asidi eqinile ne-alkali. Ifanele ukushisisa izinhlobonhlobo zoketshezi; Ngaphandle kwamakhemikhali, ama-graphite crucibles asetshenziswa kabanzi kwezensimbi, ukuphonsa, imishini, imboni yamakhemikhali neminye iminyango; I-graphite crucible yenziwe ngezinto ze-graphite zemvelo, ezigcina ukushisa okukhethekile komlilo okukhethekile kwe-graphite. I-graphite crucible isetshenziselwa ikakhulukazi ukuncibilikisa izinsimbi ezingenayo insimbi njengethusi, i-aluminium ne-alloy. Kunezici ezingenakubalwa ze-graphite crucible ngokwayo. Lapha sizokuklelela kafushane eyodwa noma ezimbili.
1. Ukungcola okuncane, ngoba amandla ahlanzekile njengegesi yemvelo noma igesi eliwuketshezi angasetshenziswa njengophethiloli kanye nokungcola okuncane.
2. Ukusetshenziswa kwamandla okuphansi, ngoba i-graphite crucible inokuhlela okunengqondo, isakhiwo esithuthukisiwe kanye nezinto ezintsha. Ngemuva kokuhlolwa, ukusetshenziswa kwamandla kuphansi kunohlobo olufanayo lwesithando somlilo.
I-Resistance furnace high purity graphite crucible isetshenziselwa ikakhulukazi ukuncibilikisa igolide, isiliva nezinsimbi ezingavamile.Izinsimbi ze-Ceramiczisetshenziswa kakhulu kumalabhorethri kanye nokuncibilikiswa kweplatinamu, igolide nezinsimbi ezingavamile. Ingabe i-graphite crucible ingasebenza ezingeni lokushisa eliphezulu lika-2000 ℃ ngaphansi kwesimo somoya? Ingabe izobola futhi i-oxidize ngobudlova? Ingabe izongcwaba insimbi encibilikisiwe? Okubaluleke kakhulu ukuthi i-carburizing iyabulala. Ngaphansi kwezimo ezijwayelekile, ingafinyelela kuma-degree angu-2000 emoyeni, kodwa izokhipha i-oxidize ngokushesha. Inkinga ye-metal carburization kufanele ibe khona. Manje kukhona i-anti carburizing coating ekhethekile emakethe, okuthiwa inomthelela omuhle.
