Dub silicon carbideyog ib hom silicon carbide, feem ntau yog ua los ntawm roj av coke thiab siab -silica zoo. Nws feem ntau yog siv los ua abrasive thiab hauv qee yam khoom tsis yog- hlau.
Cov yam ntxwv ntawm dub silicon carbide:
Vim nws cov khoom ruaj khov, thermal conductivity, qis coefficient ntawm thermal expansion, thiab zoo hnav tsis kam, dub silicon carbide muaj ntau daim ntawv thov dua li siv los ua abrasive.
Piv txwv li, txheej sab hauv phab ntsa ntawm turbine impellers los yog lub tog raj kheej blocks nrog silicon carbide hmoov siv cov txheej txheem tshwj xeeb tuaj yeem txhim kho lawv cov hnav tsis kam thiab ua kom ntev lawv lub neej kev pab los ntawm 1 mus rau 2 zaug; Cov ntaub ntawv refractory ua los ntawm nws yog thermally shock resistant, me me, hnyav, siab zog, thiab muaj zog zoo - txuag cov teebmeem.
Tsawg- qib silicon carbide (muaj kwv yees li 85% SiC) yog cov deoxidizer zoo heev. Nws tuaj yeem nrawm steelmaking thiab pab tswj cov tshuaj muaj pes tsawg leeg, txhim kho steel zoo. Tsis tas li ntawd, silicon carbide yog dav siv nyob rau hauv kev tsim cov silicon carbide cua sov ntsiab lus.
Dub silicon carbide muaj qhov nyuaj heev, nrog Mohs hardness ntawm 9.5, thib ob tsuas yog pob zeb diamond (10). Nws muaj cov thermal conductivity zoo heev, yog semiconductor, thiab tiv taus oxidation ntawm qhov kub thiab txias.
Tus kheej -sharpening zog ntawm dub silicon carbide
1. Dub silicon carbide yog ib qho abrasive uas muaj ntau tshaj 99% silicon carbide. Nws lub hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, thiab nws lub zog txhua yam yog siab dua corundum, yog li nws yog siv los sib tsoo cemented carbide cov cuab yeej.
2. Black silicon carbide muaj tus kheej zoo -sharpening zog thiab feem ntau yog siv rau machining cemented carbide, titanium alloys, thiab optical iav. Nws kuj yog siv rau honing lub tog raj kheej liner thiab precision sib tsoo siab - ceev steel cov cuab yeej. Dub silicon carbide sib tsoo lub log, tsim GC lub log, yog tsim rau machining cemented carbide, iav, ceramics, thiab tsis yog -cov ntaub ntawv hlau, nrog rau cov ntaub ntawv semiconductor, siab - kub silicon carbide cua sov ntsiab lus, thiab deb -infrared qhov chaw substrates.
Vim tias nws tus kheej zoo heev -nplaum zog, dub silicon carbide yog dav siv nyob rau hauv machining daim ntaub ntawv. Nws kuj muaj cov rwb thaiv tsev zoo, tiv thaiv tshav kub, hnav tsis kam, thiab cov khoom siv tshuaj lom neeg ruaj khov heev.
