Cov khoom siv graphiteyog ib qho cuab yeej tseem ceeb uas siv dav hauv kev lag luam metallurgy. Nws yog ua los ntawm cov khoom siv graphite purity siab nrog kev tiv taus kub zoo heev thiab kev ruaj khov tshuaj lom neeg, yog li nws ua lub luag haujlwm tseem ceeb hauv cov txheej txheem metallurgy.
Ua ntej tshaj plaws, graphite crucible ua lub luag haujlwm tseem ceeb hauv kev smelting metallurgical. Lub graphite crucible muaj peev xwm tiv taus qhov kub siab heev, txog li ntau txhiab degrees Celsius, ua rau nws yog lub thawv zoo tagnrho rau kev yaj cov hlau thiab cov hlau sib xyaw. Lub graphite crucible muaj kev ua haujlwm zoo ntawm kev coj cua sov thiab tuaj yeem faib cua sov kom sib npaug kom ntseeg tau tias qhov kub ruaj khov thaum lub sijhawm yaj. Tsis tas li ntawd, lub graphite crucible kuj muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv taus qhov corrosion ntawm cov hlau thiab cov hlau sib xyaw kom ntseeg tau tias qhov huv thiab zoo ntawm cov txheej txheem yaj.
Qhov thib ob,graphite cruciblekuj ua lub luag haujlwm tseem ceeb hauv kev ua hlau casting. Lub graphite crucible siv tau ua ib feem ntawm lub pwm casting los ntim thiab nchuav cov hlau molten. Vim tias lub graphite crucible muaj cov thermal conductivity zoo thiab nws tus kheej lubrication, nws tuaj yeem pab cov hlau ntws thiab khov, thiab txo qhov tsis zoo thiab deformation ntawm lub casting. Tsis tas li ntawd, lub graphite crucible kuj tseem tuaj yeem tiv taus qhov kub siab erosion thiab oxidation ntawm cov hlau kom ntseeg tau tias qhov zoo thiab qhov tiav ntawm qhov casting.
Tsis tas li ntawd xwb, graphite crucible kuj siv tau rau lwm yam kev siv hlau. Lub graphite crucible siv tau ua tus catalyst carrier rau catalytic reactions thiab cov txheej txheem purification roj. Lub graphite crucible muaj thaj chaw siab thiab kev ruaj khov tshuaj lom neeg, uas tuaj yeem muab cov catalytic activity loj thiab pab ua kom cov tshuaj lom neeg sai dua. Tsis tas li ntawd, lubgraphite cruciblekuj tseem siv tau rau kev ua cov qauv thiab kev tshuaj xyuas hauv cov chaw soj nstuam metallurgical, muab kev txhawb nqa rau kev tshawb fawb thiab kev txhim kho cov ntaub ntawv tshiab.
Hauv ntej, graphite crucible ua lub luag haujlwm tseem ceeb hauv kev lag luam metallurgy. Nws tiv taus kub siab, corrosion thiab cua sov conduction ua rau nws yog ib qho cuab yeej zoo tshaj plaws rau kev yaj thiab casting. Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis metallurgical, kev siv graphite crucible yuav dav dua, thiab ua rau muaj kev pab tseem ceeb rau kev nce qib thiab kev txhim kho ntawm kev lag luam metallurgical.
