Graphite crucible, tseem hu ua molten tooj liab ladle, molten tooj liab, thiab lwm yam, hais txog ib hom crucible ua los ntawm firing graphite, av nplaum, silica thiab ciab li raw cov ntaub ntawv. Graphite crucibles feem ntau yog siv los smelt tooj liab, tooj dag, kub, nyiaj, zinc thiab txhuas thiab lwm yam uas tsis yog-ferrous hlau thiab lawv alloys.
Graphite crucible yog tsim los ntawm ntuj flake graphite ua cov khoom siv tseem ceeb thiab cov yas refractory av nplaum los yog carbon raws li cov ntaub ntawv. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, muaj zog thermal conductivity, zoo corrosion kuj thiab kev pab lub neej ntev. Nyob rau hauv tus txheej txheem ntawm kev siv kub kub, lub coefficient ntawm thermal expansion yog me me, thiab nws muaj ib tug tej yam strain resistance rau ceev ceev txias thiab ceev kub. Nws muaj zog corrosion kuj rau acidic thiab alkaline daws, muaj tshuaj lom neeg ruaj ntseg zoo, thiab tsis koom nrog cov tshuaj tiv thaiv thaum lub sij hawm smelting txheej txheem. Sab hauv phab ntsa ntawm cov graphite crucible yog du, thiab cov kua hlau molten tsis yooj yim rau xau thiab ua raws li cov phab ntsa sab hauv ntawm lub crucible, kom cov kua hlau muaj fluidity zoo thiab castability, thiab nws yog haum rau casting nyob rau hauv ntau yam pwm. . Vim hais tias ntawm cov yam ntxwv zoo tshaj plaws ntawm graphite crucible, nws yog dav siv rau smelting alloy cuab yeej steel thiab smelting non-ferrous hlau thiab lawv cov alloys.
