Yuav ua li cas smelt silicon carbide?

Hauv smelting ntawm silicon carbide, cov ntaub ntawv tseem ceeb yog silica raws li gangue, quartz xuab zeb; carbon-based petroleum coke; Yog tias nws yog smelting qib qis silicon carbide, tuaj yeem ua anthracite li raw khoom; Cov khoom siv pabcuam yog ntoo chips, ntsev. Silicon carbide tuaj yeem muab faib ua dub silicon carbide thiab ntsuab silicon carbide raws li xim. Ntxiv rau qhov pom tseeb qhov sib txawv ntawm cov xim, kuj tseem muaj qhov sib txawv me me ntawm cov khoom siv raw siv hauv cov txheej txheem smelting. Txhawm rau teb koj cov lus tsis txaus siab, kuv lub tuam txhab yuav tsom mus rau qhov teeb meem no rau kev piav qhia yooj yim.

Thaum smelting ntsuab silicon carbide, nws yuav tsum tau hais tias cov ntsiab lus ntawm silicon dioxide nyob rau hauv silicon tawm cov khoom yuav tsum siab npaum li sai tau thiab cov ntsiab lus ntawm impurities yuav tsum tsawg. Tab sis thaum smelting dub silicon carbide, silicon dioxide nyob rau hauv silicon raw cov ntaub ntawv yuav qis me ntsis, cov yuav tsum tau ntawm roj av coke yog siab ruaj carbon cov ntsiab lus, tshauv ntsiab lus yog tsawg dua 1.2%, volatile cov ntsiab lus yog tsawg dua 12.0%, particle loj ntawm roj av. coke tuaj yeem tswj tau hauv 2mm lossis 1.5mm hauv qab no. Thaum smelting silicon carbide, ntxiv ntoo chips tuaj yeem kho qhov permeability ntawm tus nqi. Tus nqi ntawm sawdust ntxiv yog feem ntau tswj ntawm 3% -5%. Raws li rau ntsev, nws tsuas yog siv nyob rau hauv smelting ntawm ntsuab silicon carbide.
