Hauv ntau qhov xwm txheej tsim khoom lag luam, qhov kub thiab txias ib puag ncig muaj ntau tab sis nyuaj heev. Txawm hais tias nws yog cov nplaim taws kub hnyiab thaum lub sij hawm steel smelting, high-temperature furnaces nyob rau hauv iav manufacturing, los yog high-temperature reactors nyob rau hauv tshuaj ntau lawm, nruj yuav tsum tau muab tso rau hauv high-temperature kuj ntawm cov ntaub ntawv. Muaj cov khoom siv uas ua lub luag haujlwm tseem ceeb hauv cov teb kub kub thiab tsis tuaj yeem tsis quav ntsej, uas yogsilicon carbide tshav kub-resistant blocks.
Silicon carbide, los ntawm cov tshuaj muaj pes tsawg leeg foundations, yog ib tug compound ntawm ob lub ntsiab: silicon (Si) thiab carbon (C). Txawm hais tias muaj lo lus 'silicon' nyob rau hauv nws lub npe, nws cov tsos txawv heev ntawm cov ntaub ntawv silicon peb pom hauv peb lub neej niaj hnub. Silicon carbide feem ntau tshwm li cov xim dub lossis ntsuab, nrog rau kev ntxhib los mos thiab siab hardness. Thaum siv los khawb iav, nws yuav yooj yim tawm cov cim ntawm lub khob, ib yam li txiav butter nrog rab riam me me.
Yog vim li cas vim li cas silicon carbide tshav kub-resistant blocks tuaj yeem sawv tawm hauv qhov chaw kub kub yog vim lawv cov khoom zoo heev. Ua ntej, nws muaj ultra-siab kub tsis kam, nrog lub siab melting point, uas txhais tau hais tias nws muaj peev xwm nyob ruaj khov nyob rau hauv lub high-temperature industrial cheeb tsam thiab yuav tsis yooj yim soften, deform, los yog yaj. Thaum qhov kub thiab txias nyob rau hauv cov hlau smelting rauv skyrockets, lwm yam ntaub ntawv tej zaum yuav twb tau pib "txiav lub nra", tab sis silicon carbide tshav kub-resistant blocks yuav "nyob twj ywm" thiab tsis tu ncua lub xub pwg lub luag hauj lwm ntawm kev tiv thaiv lub cub tawg lub cev thiab tswj kev tsim khoom.
Cov tshuaj stability ntawm silicon carbide tshav kub-resistant blocks kuj zoo heev. Nws muaj kev tiv thaiv zoo rau ntau yam tshuaj lom neeg, thiab nws yog ib qho nyuaj rau muaj zog corrosive acids los yog alkaline tshuaj ua rau nws puas tsuaj. Hauv kev tsim tshuaj, ntau yam tshuaj corrosive feem ntau ntsib. Siv silicon carbide tshav kub-resistant blocks raws li hauv ob sab phlu ntawm cov khoom siv tshuaj tiv thaiv tuaj yeem tiv thaiv cov cuab yeej los ntawm corroded, txuas cov cuab yeej siv lub neej, thiab txo cov nqi tsim khoom.
Ntxiv nrog rau cov khoom saum toj no, silicon carbide tshav kub-resistant blocks kuj muaj qhov hnav tsis kam thiab siab zog. Hauv qee qhov chaw kub kub nrog cov khoom siv yaig, xws li cyclone separators thiab calcination furnaces hauv cov cement nroj tsuag, silicon carbide tshav kub-resistant blocks tuaj yeem txo qhov poob los ntawm cov khoom sib txhuam vim lawv cov khoom hnav-tiv taus, ua kom cov khoom siv ua haujlwm ib txwm muaj. Nws lub zog siab ua rau nws tuaj yeem tiv taus qee qhov siab thiab kev cuam tshuam lub zog, tswj kev ncaj ncees hauv cov chaw ua haujlwm nyuaj.
Silicon carbide tshav kub-resistant blocks yog dav siv nyob rau hauv industrial teb. Hauv kev lag luam steel, nws tau siv dav hauv cov khoom siv xws li blast furnaces thiab kub blast qhov cub. Nyob rau hauv qhov cub tawg, kub-kub molten hlau thiab slag muaj qhov xav tau siab heev rau cov ntaub ntawv hauv ob sab phlu. Silicon carbide tshav kub-resistant blocks, nrog lawv cov kub tsis kam thiab yaig tsis kam, tau dhau los ua ib qho kev xaiv zoo tshaj plaws rau cov ntaub ntawv hauv ob sab phlu, ua kom ntev lub neej kev pab cuam ntawm lub qhov cub tawg thiab txhim kho kev ua haujlwm thiab kev tsim cov hlau. Nyob rau hauv lub qhov cub kub kub, silicon carbide tshav kub-resistant blocks ua hauj lwm nyob rau hauv lub tshav kub cia lub cev, uas muaj peev xwm ua tau zoo khaws thiab tso cua sov, muab cov cua kub kub rau lub qhov cub tawg thiab txhim kho kev siv hluav taws xob.
Hauv kev lag luam uas tsis yog-ferrous hlau smelting, xws li cov txheej txheem smelting ntawm txhuas, tooj liab thiab lwm yam hlau, silicon carbide tshav kub-resistant blocks kuj tseem indispensable. Lub melting kub ntawm cov hlau no kuj siab, thiab ntau yam corrosive gases thiab slag yog generated thaum lub melting txheej txheem. Silicon carbide tshav kub-resistant blocks tuaj yeem hloov tau zoo rau qhov chaw hnyav, tiv thaiv cov cuab yeej siv hluav taws xob, thiab ua kom cov smelting du ntawm cov hlau tsis muaj hlau.
Silicon carbide tshav kub-resistant blocks kuj muaj cov ntawv thov tseem ceeb hauv kev lag luam ceramic thiab iav. Ceramic firing yuav tsum tau ua nyob rau hauv high-temperature kilns. Kilns ua los ntawm cov cua sov-resistant silicon carbide blocks, xws li cov laug cam, cov thawv, thiab lwm yam, tuaj yeem tsis tsuas yog tiv taus qhov kub thiab txias, tab sis kuj ua kom muaj kev ruaj ntseg thiab sib xws ntawm cov khoom siv ceramic thaum lub sij hawm tua hluav taws, uas yuav pab txhim kho cov khoom siv ceramic. Hauv cov iav melting furnaces, silicon carbide tshav kub-resistant blocks yog siv rau hauv ob sab phlu thiab tshav kub cia chambers, uas muaj peev xwm tiv taus kub kub yaig thiab scouring iav kua, thaum txhim kho lub thermal efficiency ntawm lub cub tawg thiab txo lub zog noj.
Nrog kev nce qib ntawm thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm kev lag luam, daim ntawv thov kev cia siab ntawm silicon carbide tshav kub-resistant blocks yuav dav dua. Ntawm ib sab, cov kws tshawb fawb tau tshawb nrhiav cov txheej txheem npaj tshiab thiab thev naus laus zis los txhim kho kev ua tau zoo ntawm silicon carbide tshav kub-resistant blocks thiab txo cov nqi tsim khoom. Piv txwv li, los ntawm kev siv cov txheej txheem sintering tshiab, qhov ceev thiab cov qauv ntawm silicon carbide tshav kub-resistant blocks tuaj yeem nce ntxiv, yog li txhim kho lawv cov kev ua tau zoo tag nrho. Ntawm qhov tod tes, nrog kev nce sai ntawm cov kev lag luam tawm tshiab xws li lub zog tshiab thiab aerospace, qhov kev thov rau cov ntaub ntawv kub-resistant kuj tseem nce ntxiv, thiab cov silicon carbide kub-resistant blocks yuav tsum ua lub luag haujlwm ntau dua hauv cov teb no.
