Raws li ib hom carbon cov ntaub ntawv, cov hmoov graphite tuaj yeem siv tau yuav luag txhua daim teb nrog kev txhim kho txuas ntxiv ntawm kev ua cov thev naus laus zis. Piv txwv li, nws tuaj yeem siv ua cov khoom siv refractory, nrog rau cov hmoov av refractory, cov pob txha caj dab, cov khoom noj kom pleev xim thiab kub siab. Graphite hmoov thiab lwm cov khoom siv hauv nkoj tuaj yeem siv ua cov neeg ua haujlwm carburizing thaum siv hauv kev lag luam steelmaking. Carbonaceous materials used in carburizing are widely used, including artificial graphite, petroleum coke, metallurgical coke and natural graphite. Graphite siv ua tus sawv cev carburizing rau steelmaking tseem yog ib qho ntawm lub ntsiab siv ntawm av gregite hauv ntiaj teb. Cov hauv qab no ua plaub ntsuab editor qhia cov yam ntxwv ntawm high-purity graphite hmoov nyob rau hauv lub roj teeb thov:
Graphite hmoov yog dav siv raws li cov ntaub ntawv kos npe xws li elecodes, txhuam thiab cov pas nrig carbon. Graphite raws li cov khoom siv-resistant thiab lubricating yog feem ntau siv raws li roj nplua nyeem hauv kev lag luam tshuab. Lubricating roj tsis tuaj yeem siv ntawm kev kub ceev, kub siab thiab muaj kev kub siab, thaum muaj kev kub ntxhov tuaj yeem ua haujlwm tsis tau cov roj nplua nuj. Graphite hmoov muaj cov tshuaj ruaj khov zoo. Cov khoom siv yooj yim graphite hmoov muaj cov yam ntxwv ntawm corrosion tsis kam, zoo siv rau kev hloov pauv cua sov, twj tso tsheb hlau luam, twj thiab lwm yam khoom siv.
Graphite tuaj yeem siv los ua pwm rau cov iav vim yog nws cov kev nthuav dav me me thiab cov kev hloov ntawm cov cua txias sai thiab ua kom sov sai. Tom qab siv tas, cov duab nroo tau ua los ntawm cov hlau muaj qhov ntev, du tawm thiab muaj txiaj ntsig zoo, thiab ua tau zoo, yog li txuag tau ntau ntawm cov hlau ntau. Graphite hmoov tuaj yeem tiv thaiv cov rhaub dej los ntawm kev ntsuas. Cov kev sim uas muaj feem xyuam nrog cov kev sim uas muaj ntxiv uas ntxiv qee cov hmoov av uas muaj cov dej phwj tuaj yeem tiv thaiv lub rhaub dej los. Ib qho ntxiv, grapite txheej ntawm hlau cov pa, vov tsev, choj thiab pipelines tuaj yeem tiv thaiv corrosion thiab xeb.
Furuite graphite tshwj xeeb hauv kev tsim cov hmoov tsim graphite, uas yog cov txheej txheem tshwj xeeb los ntawm kev sib txuas cov yam ntxwv ntawm kev sib txhuam cov khoom siv kev lag luam. Nplai tau ua tiav crystallization, lub cev siv tshuaj zoo thiab tshuaj lom neeg, zoo ua tsis kam, kev coj tawm tsam thiab tus kheej.
