Kev lag luam refractory graphite crucible rau txhuas thiab tooj liab smelting yog siab - kub- resistant thawv ua los ntawm siab - purity flake graphite ua cov khoom tseem ceeb, ntxiv nrog rau cov khoom siv ntxiv xws li silicon carbide thiab av nplaum refractory. Nws yog tsim los ntawm siab -kub sintering thiab ua tiav. Nws yog tsim tshwj xeeb rau cov txheej txheem smelting ntawm txhuas, tooj liab thiab lawv cov alloys thiab yog dav siv nyob rau hauv foundries, hlau ua cov nroj tsuag, alloy cov ntaub ntawv chaw soj nstuam, thiab lwm yam.
Qhov sib txawv tseem ceeb ntawm hom crucible no thiab zoo tib yam graphite crucibles nyob rau hauv qhov tseeb hais tias nws tau undergone formula optimization thiab structural tsim los hais txog lub siab reactivity thiab corrosiveness ntawm molten txhuas thiab tooj liab. Nws muaj kev tiv thaiv zoo rau txhuas cov kua dej nkag, tooj liab kua yaig, thiab thermal shock stability, uas tuaj yeem ua kom ntev kev pab cuam lub neej thiab txo qhov kev pheej hmoo ntawm cov hlau paug.Qhov txawv ntawm hom crucible thiab zoo tib yam graphite crucibles nyob rau hauv qhov tseeb tias nws tau undergone formula optimization thiab structural tsim los hais txog lub siab reactivity thiab corrosive thiab molper copper ntawm txhuas. Nws muaj kev tiv thaiv zoo rau txhuas cov kua dej nkag, tooj liab kua yaig, thiab thermal shock stability, uas tuaj yeem ua kom ntev kev pab cuam lub neej thiab txo qhov kev pheej hmoo ntawm cov hlau paug. Raws li cov txheej txheem yuav tsum tau, nws tuaj yeem muab faib ua ntau hom xws li silicon carbide reinforced hom, siab -purity graphite hom, thiab av nplaum graphite composite hom, muaj peev xwm xws li 1kg rau qhov chaw kuaj specifications mus rau ntau tshaj 500kg rau industrial loj furnaces.
Cov khoom muaj pes tsawg leeg thiab txheej txheem ntau lawm
Cov ntaub ntawv tseem ceeb: Siv siab -purity flake graphite nrog cov ntsiab lus ntawm cov pa roj carbon monoxide ntau dua lossis sib npaug li 99.5%, ua ke nrog cov khoom siv silicon carbide raws li theem txhawb zog nrog SiC cov ntsiab lus ntawm 30% - 60%. Lub binder yog siab -kub resistant resin los yog asphalt. Qee cov khoom siab- kawg kuj ntxiv cov tshuaj tiv thaiv antioxidant xws li ZrB₂.
Qhov tseem ceeb technical parameter
Ua haujlwm kub ntau: 1200℃- 1800 degree, tuaj yeem tiv taus qhov kub siab tshaj 2000℃rau lub sijhawm luv
Thermal conductivity: 80 - 220W/(m・K), 2-3 npaug ntawm cov av nplaum zoo tib yam
Thermal shock resistance: ΔT Ntau dua los yog sib npaug rau 800 degree, tsis tawg sai sai thiab cua sov
Aluminium erosion tsis kam: Qhov tob tob tsawg dua los yog sib npaug rau 0.5mm, kev pabcuam lub neej yog 3-5 npaug ntawm cov crucibles zoo tib yam
Txoj kev tsim
Cold isostatic pressing forming: Ensures uniform density of the crucible (>=1.85g/cm³), excellent thermal shock resistance, suitable for large industrial furnaces
Pwm pressing forming: High efficiency efficiency, haum rau standardized khoom ntawm nruab nrab thiab me me qhov ntau thiab tsawg
Isostatic pressing + machining composite txheej txheem: Txaus siab rau cov kev xav tau ntawm cov duab nyuaj, nrog rau sab hauv roughness ncav cuag Ra Tsawg dua lossis sib npaug rau 0.8μm
Sintering txheej txheem: Nws mus txog peb theem: 1000℃qis-kub preheating, 1800℃nruab nrab-kub carbonization, thiab 2200℃siab-kub graphitization. Eventually, a finished product with dense structure and excellent thermal conductivity is formed.
Kev kho saum npoo: Rau siab- cov khoom kawg, nano- nplai SiC txheej lossis oxidation- tiv thaiv impregnation kho tau raug saws. Cov hlau residue tus nqi tuaj yeem tswj tau qis dua 0.3%, txo qhov kev pheej hmoo ntawm kev kis kab mob los ntawm txhuas- tooj liab molten hlau.
