Silicon carbon hlauyog ib hom tshiab ntawm high-tech alloy tsim los ntawm silicon, carbon thiab hlau alloy. Vim nws cov kev ua tau zoo heev thiab tus nqi qis, nws yog dav siv hauv steelmaking thiab foundry kev lag luam. Piv nrog ferrosilicon, silicon-carbon alloys muaj ntau yam zoo, xws li qis coefficient ntawm thermal expansion, thermal conductivity, siab corrosion kuj, thiab zoo deoxidation thiab desulfurization muaj peev xwm.
Hlau casting
Silicon carbon alloys tuaj yeem hloov pauv ferrosilicon hauv cov hlau cam khwb cia. Ua ntej, silicon carbon alloys tuaj yeem txo tus nqi ntawm npua hlau siv rau casting, yog li txo cov nqi tsim khoom. Thib ob, piv nrog ferrosilicon, silicon carbon alloy tuaj yeem txo qhov loj ntawm graphite npas hauv cam khwb cia hlau thiab ua rau kev faib cov pob graphite ntau dua. Nws tuaj yeem txhim kho cov cuab yeej cuab tam ntawm castings. Thirdly, silicon carbon alloy muaj cov khoom zoo los tiv thaiv kev laus thiab tiv thaiv oxidation, uas tuaj yeem ua kom ntev kev pab cuam lub neej ntawm casting.
Kev ua hlau
Thaum silicon carbon alloy siv hauv steelmaking, nws tuaj yeem hloov pauv ferrosilicon hauv cov txheej txheem smelting. Nws muaj tus nqi deoxidation siab thiab muaj zog desulfurization muaj peev xwm. Silicon-carbon alloy tuaj yeem tshem tawm cov pa oxygen thiab sulfur hauv cov hlau thiab txhim kho cov hlau zoo. Tsis tas li ntawd, cov ntsiab lus ntawm cov pa roj carbon thiab silicon hauv silicon carbide alloy tuaj yeem hloov kho raws li qhov xav tau ntawm cov txheej txheem tsim khoom, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau thiab txo cov kev siv hluav taws xob hauv cov txheej txheem smelting.
Kev tsim khoom ntawm silicon carbide
Silicon-carbon alloys kuj tseem siv tau los ua cov khoom siv raw rau kev tsim cov silicon carbide, cov khoom siv refractory siab. Silicon carbide muaj qhov kub thiab txias tsis kam, siab thermal conductivity thiab zoo txhua yam khoom. Nws yog dav siv nyob rau hauv ntau yam kev lag luam, xws li metallurgy, machinery thiab electronics. Nrog rau kev txhim kho tas mus li ntawm silicon-carbon alloy kev ua tau zoo, nws yuav tsum tau hloov ib feem loj ntawm cov khoom siv raw khoom siv hauv kev tsim cov silicon carbide, thiab txuas ntxiv nthuav nws cov ntawv thov.
