Metallurgical Product Description
Dub silicon carbideyog ua los ntawm quartz, roj av, thiab coke li raw cov ntaub ntawv, nrog ib tug me me ntawm cov ntoo chips ntxiv, thiab yog smelted nyob rau hauv ib tug high-kub tiv taus rauv saum toj no 1700 degree. Nws muaj zog ntau dua li ntsuab silicon carbide thiab dav siv hauv cov khoom siv abrasives, thiab cov cuab yeej sib tsoo, thiab tuaj yeem ua rau cov iav kho qhov muag, sib tsoo thiab polishing ntawm cemented carbide, titanium alloy, thiab bearing steel sharpening ntawm high-speed steel cov cuab yeej, thiab lwm yam.

Khoom zoo
Dub silicon carbide yog cov khoom siv tshwj xeeb uas tsis muaj tshuaj lom nrog cov tshuaj formula SiC. Nws muaj cov khoom zoo xws li siab hardness, zoo thermal stability, thiab muaj zog corrosion kuj. Nws yog feem ntau siv nyob rau hauv high-temperature structural ceramics, refractory cov ntaub ntawv, abrasives, thiab lwm yam teb.
Kev tsim khoom ntawm dub silicon carbide
Nyob rau hauv cov txheej txheem ntawm kev npaj dub silicon carbide, SiC feem ntau yog tsim los ntawm reacting silicon hmoov thiab carbon hmoov nyob rau hauv high-temperature mob. Txoj kev no yog qhov yooj yim thiab tus nqi qis thiab siv dav hauv kev tsim khoom.
Kev siv cov dub silicon carbide
Cov qauv siv lead ua ntawm cov xim dub silicon carbide tuaj yeem muab faib ua cubic crystal daim ntawv thiab hexagonal siv lead ua daim ntawv, thiab lawv cov khoom thiab kev siv kuj txawv. Cubic siv lead ua dub silicon carbide feem ntau yog siv rau hauv cov ntaub ntawv abrasive, thaum hexagonal dub silicon carbide feem ntau siv rau hauv cov ntaub ntawv kub thiab hluav taws xob.
Dub silicon carbide yog dav siv nyob rau hauv metallurgical kev lag luam. Hauv cov txheej txheem metallurgical, dub silicon carbide tuaj yeem siv los ua cov khoom siv refractory hauv ob sab phlu, hauv qab, thiab thaj ua rau thaj chaw kub kub. Nws muaj cov hluav taws kub zoo thiab thermal poob siab tsis kam thiab tuaj yeem tiv taus qhov kub thiab txias thiab kub hloov pauv, ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv hlau.
Silicon carbide tuaj yeem decompose hauv molten steel thiab hnov mob nrog oxygen thiab hlau oxides hauv cov hlau molten los tsim cov pa roj carbon monoxide thiab silicon-muaj slag. Yog li, nws tuaj yeem siv los ua tus neeg ua haujlwm huv rau smelting steel, uas yog, raws li deoxidizer thiab cam khwb cia hlau qauv txhim kho rau steel ua. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tsim silicon tetrachloride.
