M'mafakitale a ng'anjo zowotchera ngalande ndi mapaipi, malo otentha kwambiri amakhala ngati "phiri lamoto" - zida za zida ziyenera kupirira kuwotcha kwanthawi yayitali kuposa 800 ℃, komanso kukana kukokoloka kwa mpweya wotulutsa okosijeni komanso ngakhale mpweya wa acidic. Zida zachitsulo zachikhalidwe zimakhala zosavuta kufewetsa ndi kusinthika m'dera lino, zomwe zimapangitsa kuti moyo ukhale wochepa mwadzidzidzi. Komabe,ndodo yozungulira yozungulira yopangidwa ndi silicon carbide (SiC)zakuthupi zili ngati "womenyera kutentha kwambiri", kudalira jini yake yolimbana ndi kutentha, kukhala "nangula wa kunyanja" kuti azigwira ntchito mokhazikika pamawotchi otentha kwambiri.
Chifukwa chomwe ma silicon carbide square beam rollers amatha kukhala "wosewerera ace" m'munda wotentha kwambiri ndi chifukwa cha zida zawo zapadera:
1. Pangani chotchinga chodzipangira nokha "thermal chotchinga"
Kutentha kukapitilira 1200 ℃, filimu yowuma ya silicon dioxide (SiO ₂) imapangika yokha pamwamba pa silicon carbide. Izi wosanjikiza "zida mandala" sangathe kudzipatula mwachindunji zotsatira za kutentha pamwamba pa gawo lapansi, komanso kukana malowedwe a mpweya acidic, kukwaniritsa "awiri chitetezo dzimbiri kutentha kwambiri".
2. Kutentha kumafika, kumakhala kolimba
Mosiyana ndi zomwe zitsulo zachitsulo zimakhala zofewa zikatenthedwa, silicon carbide sikuti imangokhala ndi mphamvu yopindika pa kutentha kwakukulu kwa 800 ℃ -1350 ℃, komanso imasonyeza kuwonjezereka kwina. Izi "zotsutsana ndi zomwe zikuchitika" zimalola kuti chodzigudubuza chikhalebe cholimba m'malo otentha kwambiri, kupewa kugwa kwapangidwe chifukwa cha kufewetsa.
3. Thermal "teleportation master"
Thermal conductivity ya silicon carbide ndi kuwirikiza kanayi kuposa chitsulo, chomwe chimatha kufalitsa mwachangu komanso mofananamo kutentha kwanuko ngati "msewu waukulu wotentha", kupeŵa kudzikundikira kwa "malo otentha" mung'anjo. Khalidweli osati amateteza wodzigudubuza palokha, komanso amakhala bata la desulfurization anachita kutentha, kuwongolera wonse dzuwa.
Wobadwira m'mafakitale otentha kwambiri
Kutsika kwa kutentha kwa ma silicon carbide square beam rollers kumawapangitsa kukhala opambana kwambiri pazigawo zotentha kwambiri za desulfurization monga ma boiler amagetsi otenthetsera, sintering zitsulo, komanso kusweka kwa mankhwala. Pambuyo potengera chigawo ichi, mabizinesi amatha kuchepetsa kuchuluka kwa kutsekeka kwa kutentha kwambiri ndi kukonza, pomwe akukulitsa moyo wautumiki wa zida mpaka kangapo pazinthu zachikhalidwe, kukwaniritsa "kutentha kwambiri popanda kutseka, kuteteza chilengedwe popanda kuzizira".
Monga bizinesi yatsopano yomwe imagwira ntchito pa kafukufuku ndi chitukuko cha zida za silicon carbide ceramic, tikudziwa bwino za ululu wa zida pansi pamikhalidwe yovuta kwambiri yogwirira ntchito. Chogudubuza chilichonse cha silicon carbide square beam chimaphatikizapo kufufuza kwakukulu kwa sayansi ya zipangizo. M'tsogolomu, tidzapitiriza kuganizira za "kutentha kwakukulu" monga njira yopita patsogolo, ndikugwiritsa ntchito mphamvu zamakono kuteteza mzere wobiriwira wa chitetezo cha mafakitale.
