I-graphite crucible, eyaziwa nangokuthi i-copper ladle encibilikisiwe, ithusi elincibilikisiwe, njll., ibhekisela ohlotsheni lwe-crucible eyenziwe ngokudubula i-graphite, ubumba, i-silica kanye ne-wax njengezinto zokusetshenziswa. I-graphite crucibles isetshenziselwa ikakhulukazi ukuncibilikisa ithusi, ithusi, igolide, isiliva, i-zinc nomthofu nezinye izinsimbi ezingenayo insimbi nama-alloys azo.
I-graphite crucible yenziwe nge-graphite ye-flake yemvelo njengento eluhlaza eyinhloko kanye nobumba lwe-plastic refractory noma ikhabhoni njengesibophezelo. Inezici zokumelana nokushisa okuphezulu, ukuguquguquka okuqinile kwe-thermal, ukumelana nokugqwala okuhle nempilo ende yesevisi. Enkambweni yokusetshenziswa kokushisa okuphezulu, i-coefficient yokwanda okushisayo incane, futhi inokumelana nokucindezeleka okuthile ekushiseni okubandayo nokushisa okusheshayo. Inokumelana nokugqwala okuqinile ezixazululweni ezine-asidi ne-alkaline, inokuqina okuhle kwamakhemikhali, futhi ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali phakathi nenqubo yokuncibilikisa. Udonga lwangaphakathi lwe-graphite crucible lubushelelezi, futhi uketshezi lwensimbi oluncibilikisiwe akulula ukuvuza nokunamathela odongeni lwangaphakathi lwe-crucible, ukuze insimbi ye-liquid ibe ne-fluidity enhle ne-castability, futhi ifanele ukuphonswa ezibunjeni ezihlukahlukene. . Ngenxa yezici ezinhle kakhulu ezibalulwe ngenhla ze-graphite crucible, isetshenziswa kakhulu ekuncibilikiseni insimbi yensimbi eyingxubevange nokuncibilikisa izinsimbi ezingenayo insimbi nama-alloys azo.
