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 tiv thaiv cov khoom kub kub, uas tuaj yeem tiv thaiv cov flake graphite los ntawm oxidation ntawm qhov kub thiab txias. Yuav kom nrhiav tau hom graphite los 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 editor ntawm Furuite Graphite qhia cov txheej txheem ntawm kev tiv thaiv flake graphite los ntawm oxidized ntawm kub:
1. Cov khoom siv nrog lub zog siab tsawg dua 0.1333MPa (1650 ℃) thiab cov khoom siv zoo tau txais yuav.
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 ua cov khoom tawg sealing hauv qhov kub thiab txias.
3. Raws li kev hloov pauv ntawm cov qauv dawb lub zog ntawm cov tshuaj tiv thaiv nrog oxygen nrog qhov kub thiab txias, ntawm qhov kub ntawm steelmaking (1650-1750 ℃), xaiv cov khoom uas muaj kev sib raug zoo nrog cov pa oxygen ntau dua li carbon-oxygen, tuav cov pa ua ntej, thiab oxidize lawv tus kheej los tiv thaiv. flake graphite. Lub ntim ntawm cov theem tshiab tsim tom qab oxidation yog loj dua li ntawm cov thawj theem, uas yuav pab tau los thaiv cov inward diffusion channel ntawm oxygen thiab tsim oxidation barrier.
4. Thaum ua hauj lwm kub, nws muaj peev xwm nqus tau ib tug loj tus naj npawb ntawm inclusions xws li AL2O3, SiO2, Fe2O3 nyob rau hauv molten steel, thiab react nrog nws tus kheej mus rau sinter, kom ntau inclusions los ntawm molten steel maj nkag mus rau lub txheej.
Furuite Graphite Xiaobian ceeb toom tias oxidation kub ntawm flake graphite nyob rau hauv Tuam Tshoj lub ntsiab tsim cov cheeb tsam yog 560,815 ℃ thaum cov ntsiab lus carbon yog 88% 96% thiab particle loj yog siab tshaj -400 mesh. Ntawm lawv, thaum qhov me me ntawm graphite yog 0.0970.105mm, oxidation kub ntawm graphite nrog ntau tshaj 90% cov ntsiab lus carbon yog 600,815 ℃, thiab cov graphite nrog tsawg dua 90% cov ntsiab lus carbon yog 6200 ℃. Qhov zoo dua cov crystalline flake graphite, qhov siab dua qhov oxidation ncov kub thiab qhov tsawg dua qhov oxidation poob ntawm qhov kub thiab txias.
