Yuav ua li cas txheeb xyuas qhov teeb meem zoo hauv Silicon Carbide khoom

Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, kuv lub teb chaws kev lag luam cement yog niaj hnub txhim kho nws cov kev txawj ntse, yog li tsa cov kev cai rau cov khoom siv refractory. Cov khoom siv silicon carbide tau siv dav hauv kev lag luam cement vim lawv qhov siab -kub tsis kam. Yog li, yuav ua li cas thiaj paub qhov zoo ntawm cov khoom siv silicon carbide?

Yuav ua li cas txheeb xyuas qhov teeb meem zoo hauv Silicon Carbide khoom

Ib txoj hauv kev yooj yim rau kev kuaj xyuas cov khoom zoo ntawm silicon carbide yog coj mus rhaub rau hauv nruab nrab ntawm cov khoom siv rauj thiab mloog lub suab. Yog hais tias lub suab yog npub, nws qhia tau hais tias cov khoom silicon carbide muaj voids los yog delamination nyob rau hauv qhov chaw, ua rau nws tsis haum rau lub tsev cement kilns. Yog hais tias lub suab yog txawm tab sis muaj ib tug reverberation, nws qhia tau hais tias lub internal qauv ntawm cov khoom silicon carbide yog lawm thiab nws yuav siv tau rau kev ua. Yog hais tias lub suab yog nkig, zoo li lub suab ntawm cov hlau, nws qhia tau hais tias cov khoom silicon carbide muaj ib tug high℃ntawm sab hauv sintering, ua rau nws nyuaj rau txheej txheem.

Cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv silicon carbide kuj txiav txim siab lawv cov khoom tshwj xeeb. Piv txwv li, lawv nyob twj ywm nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias hloov ceev, tuaj yeem tiv taus siab thaum lub sij hawm shearing, thiab tsis yooj yim deformed ntawm qhov kub thiab txias, txhais tau tias lawv muaj zog tiv taus kub.

Cov qauv tseem ceeb ntawm Silicon Carbide khoom

Hauv kuv lub tebchaws, cov khoom lag luam silicon carbide tau muab faib ua dub silicon carbide thiab ntsuab silicon carbide. Yog li, yam twg ntawm silicon carbide yuav tsum tau siv thaum tsim khoom silicon carbide? Hauv qab no, cov chaw tsim khoom lag luam silicon carbide yuav muab cov ncauj lus kom ntxaws txog qhov teeb meem no.

Silicon carbide cov khoom lag luam muaj ob hom matrices: dub silicon carbide thiab ntsuab silicon carbide, ob qho tib si yog cov tsev neeg SiC.

1. Dub silicon carbide muaj kwv yees li 95% SiC thiab muaj zog ntau dua li ntsuab silicon carbide. Nws yog tsuas yog siv rau kev ua cov ntaub ntawv uas tsis muaj zog tensile, xws li iav, ceramics, pob zeb, refractory cov ntaub ntawv, cam khwb cia hlau, thiab tsis yog -ferrous hlau.

2. Ntsuab silicon carbide muaj ntau dua 97% SiC thiab muaj tus kheej zoo - ntse zog. Nws yog tsuas yog siv rau machining cemented carbide, titanium alloys, thiab kho qhov muag iav, nrog rau rau honing lub tog raj kheej liners thiab sib tsoo siab - ceev steel cov cuab yeej. Tsis tas li ntawd, muaj cubic silicon carbide, lub yellowish -ntsuab siv lead ua ua los ntawm cov txheej txheem tshwj xeeb. Abrasives ua los ntawm nws yog haum rau ultra- precision machining ntawm bearings, ua tiav nto roughness ntawm Ra32 ~ 0.16 micrometers mus rau Ra0.04 ~ 0.02 micrometers nyob rau hauv ib zaug xwb.

Hom thiab Kev Siv Cov Khoom Siv Silicon Carbide

1. Cov ntawv thov hauv Non-ferrous Hlau Smelting Kev Lag Luam

Silicon carbide muaj qhov kub thiab txias tsis kam, siab zog, zoo thermal conductivity, thiab kev cuam tshuam tsis kam, ua rau nws haum raws li qhov kub siab - kub tsis ncaj cov khoom siv cua sov, xws li nyob rau hauv ib qho nyuaj - ntim distillation furnaces. Cov ntawv thov suav nrog cov tshuab hluav taws xob distillation, aluminium electrolytic hlwb, tooj liab smelting rauv hauv ob sab phlu, arc daim hlau rau zinc hmoov furnaces, thiab thermocouple tiv thaiv raj.
2. Kev siv hauv kev lag luam hlau

Siv silicon carbide corrosion kuj, thermal poob siab tsis kam, thiab hnav tsis kam, nrog rau nws cov thermal conductivity zoo, nws tuaj yeem siv rau hauv cov kab hluav taws xob loj loj kom ntev lawv lub neej kev pab cuam. Siv nws cov thermal conductivity, siab kub dissipation, thiab siab thermal zog, silicon carbide yog siv los tsim nyias- phaj kiln rooj tog. Qhov no tsis yog tsuas yog txo cov rooj tog zaum ntawm cov rooj tog zaum xwb tab sis kuj ua rau nws nce, txhim kho cov khoom zoo, thiab ua kom lub voj voog ntau lawm. Nws yog ib qho khoom siv zoo tshaj plaws rau kev tua hluav taws thiab sintering ceramic glazes.

3. Cov ntawv thov hauv Metallurgical thiab Mineral Processing Industries

Silicon carbide muaj qhov hardness thib ob rau pob zeb diamond thiab muaj zog hnav tsis kam. Nws yog ib qho khoom siv zoo tshaj plaws rau hnav- cov kav dej tiv taus, impellers, twj tso kua mis, cov tshuab hluav taws xob sib cais, thiab cov hopper hauv ob sab phlu. Nws hnav tsis kam yog 5-20 npaug ntawm cov hlau cam khwb cia thiab roj hmab, ua rau nws yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau cov dav hlau khiav.
