Txhawm rau tiv thaiv kev puas tsuaj los ntawm oxidation ntawm flake graphite ntawm qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum nrhiav cov khoom siv los muab lub tsho rau cov khoom siv kub, uas tuaj yeem tiv thaiv cov flake graphite los ntawm oxidation ntawm qhov kub thiab txias. Yuav kom nrhiav tau hom flake graphite tiv thaiv oxidation lub tsho tiv no, peb yuav tsum xub muaj qee yam ntxwv xws li kub tsis kam, zoo compactness, zoo anti-corrosion kev ua tau zoo, muaj zog tiv thaiv oxidation muaj peev xwm thiab siab hardness. Cov nram qab no Furuite graphite editors qhia cov txheej txheem los tiv thaivflake graphitelos ntawm kev oxidized ntawm qhov kub thiab txias:
1. Siv cov khoom siv nrog vapor siab tsawg dua 0.1333MPa (1650 ℃) thiab cov khoom zoo.
2. Xaiv cov khoom siv iav theem uas ua tau raws li qhov yuav tsum tau ua raws li cov khoom siv sealing tus kheej, thiab ua kom nws dhau los ua cov khoom sib khi ntawm qhov kub thiab txias.
3. Raws li kev ua haujlwm ntawm tus qauv dawb lub zog ntawm cov tshuaj tiv thaiv nrog oxygen nrog qhov kub thiab txias, ntawm steelmaking kub (1650-1750 ℃), cov ntaub ntawv uas muaj affinity ntau dua rau cov pa roj carbon-oxygen yog xaiv los coj oxygen ua ntej, yog li ntawd oxidize lawv tus kheej thiab tiv thaiv covflake graphite. Lub ntim ntawm cov theem tshiab tsim tom qab oxidation yog loj dua li ntawm cov thawj theem, uas yog pab los thaiv cov inward diffusion channel ntawm oxygen thiab tsim ib tug oxidation barrier.
4. Thaum ua haujlwm kub, muaj ntau qhov sib xyaw xws li Al2O3, SiO2 thiab Fe2O3 hauv molten steel tuaj yeem adsorbed, uas cuam tshuam nrog lawv tus kheej rau sinter, kom ntau yam kev suav nrog cov hlau molten maj mam nkag mus rau txheej.
Furuite graphite ceeb toom peb tias oxidation kub ntawm flake graphite nyob rau hauv Tuam Tshoj lub ntsiab ua qhov chaw yog 560815 ℃ thaum cov ntsiab lus carbon yog 88% 96% thiab particle loj yog siab tshaj -400 mesh. Ntawm lawv, thaum qhov loj me ntawm graphite yog 0.0970.105mm, oxidation kub ntawm graphite nrog ntau tshaj 90% cov ntsiab lus carbon yog 600815 ℃ thiab cov graphite nrog tsawg dua 90% cov ntsiab lus carbon yog 62075 ℃. Qhov ntau crystallineflake graphiteyog, qhov siab dua qhov oxidation ncov kub yog, thiab qhov tsawg dua qhov oxidation poob ntawm qhov kub siab yog.
