Hauv cov xwm txheej kev lag luam kub siab, kev ua tau zoo ntawm cov khoom siv hauv tsev txiav txim siab ncaj qha rau kev ua haujlwm zoo ntawm kev tsim khoom, kev nyab xeeb thiab kev tswj tus nqi.Cov hlau nplaum silicon carbide (SiC)tau tshwm sim los ua ib qho kev hloov pauv loj, hloov cov khoom siv ib txwm muaj xws li hlau thiab alumina ceramics nrog lawv qhov kev tiv taus kub siab, kev tiv taus corrosion thiab kev ruaj khov ntawm cov qauv. Tsim los rau kev ruaj khov thiab kev hloov pauv tau, peb cov kab hlau SiC kev cai ua rau muaj kev xav tau ntau yam kev lag luam, xa cov kev ua tau zoo hauv qhov chaw nyuaj tshaj plaws.
Cov kab teeb silicon carbide siv tau rau ntau yam lag luam kub siab, ua rau lawv tseem ceeb heev. Feem ntau, lawv siv dav ua cov qauv thauj khoom thiab cov rooj tog zaum hauv qhov cub hauv cov qhov cub, suav nrog qhov cub tunnel, shuttle kilns, roller kilns thiab bell kilns. Cov kab teeb no dais qhov hnyav ntawm cov khoom ntawm lub tsheb kilns thiab txhawb nqa cov qauv refractory ntawm lub ru tsev ntawm lub cub tawg, ua kom muaj kev ua haujlwm ruaj khov txawm tias nyob rau hauv kev ci ntev ntawm qhov kub txog li 1380 ℃. Lawv yog qhov tsim nyog tshwj xeeb rau cov txheej txheem sintering hauv cov khoom siv ceramic, hmoov ceramic hluav taws xob, cov khoom siv huv, cov khoom siv roj teeb lithium positive thiab negative, thiab cov khoom siv refractory.
Ntxiv rau kev siv rau hauv qhov cub, SiC beams zoo heev rau lwm yam xwm txheej uas xav tau ntau. Lawv txoj kev tiv thaiv oxidation zoo heev thiab kev ruaj khov tshuaj lom neeg ua rau lawv zoo tagnrho rau kev siv hauv cov boilers fais fab thermal, steel sintering thiab cov txheej txheem tawg tshuaj, qhov twg lawv tiv taus kev yaig los ntawm oxidizing thiab acidic gases. Tsis tas li ntawd, lawv qhov kev ntshiab siab thiab lub zog ntawm cov qauv ua rau lawv siv tau rau hauv cov cuab yeej kub siab hauv aerospace thiab semiconductor manufacturing, txhawb kev txhim kho ntawm cov lag luam tshiab. Piv rau cov ntaub ntawv ib txwm muaj, SiC beams muaj lub neej ua haujlwm ntev dua 5-6 npaug, txo qhov zaus txij nkawm thiab cov nqi hloov pauv.
Peb nkag siab tias txhua qhov project kev lag luam muaj cov kev xav tau tshwj xeeb, yog vim li cas peb thiaj muab cov kev daws teeb meem silicon carbide square beam uas tau hloov kho tag nrho. Peb qhov kev pabcuam hloov kho kom haum rau txhua yam tseem ceeb kom phim koj cov kev xav tau tshwj xeeb. Ua ntej, kev hloov kho qhov ntev: peb tsim cov beams nrog qhov loj me ntawm 30 × 30mm txog 120 × 120mm thiab dhau ntawd, nrog rau phab ntsa tuab tuaj yeem hloov kho raws li koj qhov kev xav tau thauj khoom. Peb kuj muab cov tshuab tshwj xeeb, xws li qhov drilling, qhov ntev lossis qhov, kom ntseeg tau tias muaj kev sib koom ua ke zoo meej nrog koj cov khoom siv uas twb muaj lawm.
Qhov thib ob, kev kho cov khoom siv: peb muaj kev xaiv sintered (SiSiC/RSiC) thiab recrystallized (RC-SiC), nrog rau cov ntsiab lus SiC txij li 85% txog 99%, kom sib npaug kev ua tau zoo thiab tus nqi. Txhua lub beam customized raug kuaj xyuas zoo nruj, suav nrog kev ncaj (≤1‰) thiab kev sim lub zog khoov (txog li 280MPa ntawm 1200 ℃), kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb. Peb kuj muab cov ntim khoom thiab kev xa khoom thoob ntiaj teb kom ntseeg tau tias koj cov khoom tuaj txog zoo thiab raws sijhawm.
Ua ib lub chaw tsim khoom SiC tshaj lij, peb muab cov thev naus laus zis sintering siab heev nrog ntau xyoo ntawm kev paub hauv kev lag luam los xa cov kev daws teeb meem zoo. Peb cov silicon carbide square beams tsis yog tsuas yog ua tau raws li koj cov kev xav tau kev ua haujlwm xwb tab sis kuj pab txo kev siv hluav taws xob thiab txhim kho kev ua haujlwm zoo. Txawm hais tias koj xav tau qhov loj me, cov qauv tsim tshwj xeeb, lossis cov lus qhia txog kev siv tshuab uas haum rau koj txoj kev lag luam, hu rau peb hnub no kom tau txais kev hais nqe dawb, tsis muaj kev lav phib xaub thiab kev sab laj tshaj lij. Cia peb cov SiC square beams ua haujlwm tau zoo, ua kom koj cov haujlwm kub siab—txhawb kev ruaj khov, txiav cov nqi, thiab tsa koj cov peev xwm tsim khoom.
