Ukuphonononga iibhloko zeSilicon Carbide ezikwaziyo ukumelana nobushushu: Ngasemva kweSigcawu seQhawe loShishino loBubushushu obuphezulu

Kwiimeko ezininzi zemveliso yamashishini, iindawo zokushisa eziphezulu ziqhelekileyo kodwa zinzima kakhulu. Ingaba ngamadangatye avuthayo ngexesha lokunyibilika kwentsimbi, iziko lobushushu obuphezulu kwimveliso yeglasi, okanye i-reactors yobushushu obuphezulu kwimveliso yeekhemikhali, iimfuno ezingqongqo zibekwe ekuxhathiseni ubushushu obuphezulu bezinto. Kukho imathiriyeli edlala indima ebalulekileyo kula mimandla yobushushu obuphezulu kwaye ayinakungahoywa,iibhloko zesilicon carbide ukumelana nobushushu.
I-Silicon carbide, ukusuka kumbono wokwakheka kweekhemikhali, i-compound eyenziwe ngezinto ezimbini: i-silicon (Si) kunye ne-carbon (C). Ngaphandle kwegama elithi 'silicon' egameni layo, ukubonakala kwayo kwahluke kakhulu kwizinto ze-silicon esizibona kubomi bethu bemihla ngemihla. I-silicon carbide ngokuqhelekileyo ibonakala njengeekristale ezimnyama okanye eziluhlaza, ezinobunzima obunzima kunye nobunzima obuphezulu. Xa isetyenziselwa ukukrwela iglasi, iya kushiya ngokulula amanqaku kwiglasi, njengokusika ibhotolo ngemela encinci.
Isizathu sokuba iibhloko ze-silicon carbide ezikwazi ukumelana nobushushu zinokugqama kwiindawo eziphakamileyo zobushushu kungenxa yothotho lweempawu ezigqwesileyo. Okokuqala, inokumelana nobushushu obuphezulu kakhulu, enendawo yokunyibilika ephezulu kakhulu, nto leyo ethetha ukuba inokuhlala izinzile kwindawo yeshishini elinobushushu obuphezulu kwaye ayizukuthamba lula, ikhubazeke, okanye inyibilike. Xa iqondo lobushushu ngaphakathi kwisithando somlilo esinyibilikisayo sinyuka, ezinye izinto zisenokuba sele ziqalisile “ukuthwala umthwalo”, kodwa iibhloko ze-silicon carbide ezimelana nobushushu zinokuthi “zihlale” kwaye ngokuthe ngcembe zithwale uxanduva lokukhusela umzimba wesithando somlilo nokugcina imveliso.
Ukuzinza kweekhemikhali ze-silicon carbide-resistant block blocks nako kuhle kakhulu. Inokumelana kakuhle nezixhobo ezahlukeneyo zemichiza, kwaye kunzima ukuba iiasidi ezomeleleyo ezonakalisayo okanye izinto zealkali zibangele umonakalo kuyo. Kwimveliso yeekhemikhali, iikhemikhali ezahlukeneyo ezonakalisayo zihlala zidibana nazo. Ukusebenzisa iibhloko ze-silicon carbide ezimelana nobushushu njengoko umgca wesixhobo sokusabela kunokuthintela ngokufanelekileyo isixhobo ekubeni sidleke, sandise ubomi benkonzo yezixhobo, kunye nokunciphisa iindleko zemveliso.

Ukongeza kwezi zakhiwo zingasentla, iibhloko ze-silicon carbide ezimelana nobushushu nazo zinokuxhathisa okulungileyo kokunxiba kunye namandla aphezulu. Kwezinye iindawo ezinobushushu obuphezulu obunokhukuliseko lwezinto eziphathekayo, ezifana nezahluli zesaqhwithi kunye neziko lokubala kwizityalo zesamente, iibhloko ze-silicon carbide ezikwazi ukumelana nobushushu zinokunciphisa ilahleko ebangelwa kukungqubana kwezinto ngenxa yeempawu zazo zokunxiba, ziqinisekisa ukusebenza okuqhelekileyo kwezixhobo. Amandla ayo aphezulu enza ukuba ikwazi ukumelana noxinzelelo oluthile kunye nefuthe leempembelelo, ukugcina ingqibelelo yesakhiwo kwiindawo ezinzima zoshishino.
Iibhloko ze-silicon carbide ezichasene nobushushu zisetyenziswa ngokubanzi kwintsimi yezoshishino. Kwishishini lensimbi, lisetyenziswa kakhulu kwizixhobo ezifana nezitofu eziqhumayo kunye nezitofu ezitshisayo. Ngaphakathi kwesithando somlilo, i-iron enyibilikisiweyo ephezulu yobushushu kunye ne-slag ineemfuno eziphezulu kakhulu zemathiriyeli ye-lining. Iibhloko ze-silicon carbide ezichasene nokushisa, kunye nokumelana nokushisa okuphezulu kunye nokuchasana nokukhukuliseka, ziye zaba yinto efanelekileyo yokukhetha izinto ze-lining, ukwandisa ngokufanelekileyo ubomi benkonzo yesithando somlilo kunye nokuphucula ukusebenza kakuhle kunye nomgangatho wemveliso yensimbi. Kwisithando somlilo esitshisayo, iibhloko ze-silicon carbide ezimelana nobushushu zisebenza njengemizimba yokugcina ubushushu, enokugcina ngokufanelekileyo kwaye ikhulule ubushushu, inike umoya oshushu ophezulu wobushushu bomlilo kunye nokuphucula ukusebenza kakuhle kokusetyenziswa kwamandla.
Kwishishini lokunyibilikisa isinyithi esingeyontsimbi, elifana nenkqubo yokunyibilikisa ialuminiyam, ubhedu kunye nezinye iintsimbi, iibhloko zesilicon carbide ukumelana nobushushu nazo ziyimfuneko. Ubushushu bokunyibilika kwezi zinyithi buphezulu kakhulu, kwaye iigesi ezonakalisayo ezahlukeneyo kunye ne-slag ziveliswa ngexesha lenkqubo yokunyibilika. Iibhloko zeSilicon carbide ezikwazi ukumelana nobushushu ziyakwazi ukuziqhelanisa kakuhle nemekobume enjalo, zikhusele izixhobo zesithando somlilo, kwaye ziqinisekise ukunyibilika okugudileyo kwezinyithi ezingenayo intsimbi.
Iibhloko ze-silicon carbide ezichasene nobushushu nazo zinezicelo ezibalulekileyo kumashishini e-ceramic kunye neglasi. Ukudubula kweCeramic kufuneka kuqhutyelwe kwiikhilni zobushushu obuphezulu. I-Kilns ezenziwe ngeebhloko ze-silicon carbide ezinganyangekiyo ukushisa, ezifana neebhodi zokuphalaza, iibhokisi, njl., azikwazi nje ukumelana nokushisa okuphezulu, kodwa ziqinisekisa ukuzinza kunye nokufana kweemveliso ze-ceramic ngexesha lokudubula, okunceda ukuphucula umgangatho weemveliso ze-ceramic. Kwiziko zokunyibilika kweglasi, iibhloko ze-silicon carbide ezikwaziyo ukumelana nobushushu zisetyenziselwa uphahla kunye namagumbi okugcina ubushushu, anokumelana nokhukuliseko lobushushu obuphezulu kunye nokukhukuliswa kolwelo lweglasi, ngelixa iphucula ukusebenza kakuhle kwesithando somlilo kunye nokunciphisa ukusetyenziswa kwamandla.
Ngenkqubela phambili eqhubekayo yetekhnoloji kunye nophuhliso oluzinzileyo lweshishini, amathuba okusetyenziswa kwe-silicon carbide-resistant block blocks aya kuba banzi ngakumbi. Ngakolunye uhlangothi, abaphandi bahlala behlola iinkqubo ezintsha zokulungiselela kunye nobuchwepheshe bokuphucula ngakumbi ukusebenza kweebhloko ze-silicon carbide ezichasene nobushushu kunye nokunciphisa iindleko zokuvelisa. Ngokomzekelo, ngokwamkela inkqubo entsha ye-sintering, ubuninzi kunye nesakhiwo se-silicon carbide-resistant block blocks sinokunyuswa, ngaloo ndlela kuphuculwe ukusebenza kwabo ngokubanzi. Kwelinye icala, ngokunyuka okukhawulezileyo kwamashishini asakhulayo anje ngamandla amatsha kunye ne-aerospace, imfuno yezinto ezixhathisa ubushushu obuphezulu nayo iyanda, kwaye iibhloko ze-silicon carbide ezimelana nobushushu kulindeleke ukuba zidlale indima enkulu kula mabala.
