I-Silicon Carbide Castable: Isisombululo Esigqibeleleyo Sezicelo Ezinobushushu Obuphezulu Nezingagugiyo

Kwimveliso yemizi-mveliso, amaqondo obushushu aphezulu, ukuguguleka koomatshini, kunye nokukhukuliseka kweekhemikhali zezona ntshaba zinkulu zobomi benkonzo yezixhobo kunye nokusebenza kakuhle kwemveliso. Nokuba sisithando sesinyithi, isitovu esijikelezayo sesamente, okanye isitya seekhemikhali, ukusebenza kwezinto ezichaseneyo kumisela ngokuthe ngqo uzinzo lomgca wemveliso. Phakathi kwezinto ezininzi ezichaseneyo,i-silicon carbide enokuphoswaIbalasele ngokumelana kwayo nobushushu obuphezulu, ukumelana nokuguguleka, kunye nokumelana nokugqwala, ibe yinto ebalulekileyo efunekayo kwiindawo ezahlukeneyo zoshishino ezifunwa kakhulu kwihlabathi liphela.

I-silicon carbide castable luhlobo lwezinto ezingaguqukiyo ezenziwe nge-silicon carbide (SiC) ecocekileyo kakhulu njengesixhobo esiphambili, idityaniswe nezihlanganisi ezikumgangatho ophezulu, izongezo, kunye namanzi. Ineempawu zokwakha ezilula (zingagalelwa, zixotyulwe, okanye zishukunyiswe zibe yimo), ziyakwazi ukuzivumelanisa nezakhiwo ezintsonkothileyo, kwaye zinokwenza ulwelo oluxineneyo nolulinganayo emva kokucocwa nokucocwa. Xa kuthelekiswa nezitena zemveli eziguquliweyo kunye nezinye izinto eziguquliweyo, ineengenelo ezicacileyo zokusebenza, ezinokusombulula ngempumelelo iingxaki zobomi obufutshane benkonzo kunye nokugcinwa rhoqo kwezixhobo eziguquliweyo kwiindawo ezinzima.

IiNdawo eziphambili zokusetyenziswa kweSilicon Carbide Castable

1. Ishishini leMetallurgical: Ilitye lembombo lokunyibilikisa amaqondo obushushu aphezulu

Ishishini lesinyithi lelinye lawona marhwebo makhulu asetyenziswayo kwi-silicon carbide castable. Kwii-blast furnaces, ii-converters, ii-electric arc furnaces, kunye nee-non-ferrous metal smelting furnaces (ezifana ne-aluminium, i-copper, kunye ne-zinc smelting), ii-linings ziphantsi kweemeko ezinzima ezifana namaqondo obushushu aphezulu (ukuya kuthi ga kwi-1600℃), ukuguguleka kwesinyithi esinyibilikisiweyo, kunye ne-furnace slag scouring. I-Silicon carbide castable, ene-melting point yayo ephezulu (ngaphezulu kwe-2700℃) kunye nokumelana nokuguguleka okuhle, isetyenziswa kakhulu kwi-lining yemilomo ye-furnace, ii-tapholes, ii-slag outlets, kunye nezinye iindawo ezibalulekileyo. Ingamelana ngempumelelo nokuguguleka kwesinyithi esinyibilikisiweyo, intsimbi, kunye neentsimbi ezingezizo ze-ferrous, inciphise ukuphindaphindeka kokutshintshwa kwe-lining, kwaye iphucule ixesha lokusebenza eliqhubekayo le-furnace. Umzekelo, kwii-aluminium smelting furnaces, i-silicon carbide castable isetyenziselwa i-lining yedama lokunyibilika, elinokumelana nokugqwala kwe-aluminium enyibilikisiweyo kwaye landise ubomi benkonzo ye-furnace ngaphezulu kwe-50% xa kuthelekiswa nezixhobo zemveli.

2. Ishishini lezixhobo zokwakha: Ukunyusa ukusebenza kakuhle kwesamente kunye nemveliso yeseramikhi

Kwishishini lezinto zokwakha, ii-oven zesamente ezijikelezayo, ii-oven ze-ceramic roller, kunye nee-oven zeglasi ezinyibilikayo zinemfuneko engqongqo kwizinto ezichaseneyo. I-preheater, i-cyclone separator, kunye ne-tertiary air duct yee-oven zesamente ezijikelezayo zikwimeko yobushushu obuphezulu, enothuli, kunye nokukhukuliseka kwegesi ixesha elide. Ukusetyenziswa kwe-silicon carbide castable njenge-lining akunakumelana nokuguquguquka kobushushu obuphezulu kuphela kodwa kukwathintela ngempumelelo ukukhuhla kunye nokukrala kwe-clinker yesamente kunye nothuli. Oku kunciphisa iindleko zokugcina inkqubo ye-oven kwaye kuphucula ukusebenza kakuhle kwemveliso yesamente. Kwii-oven ze-ceramic roller, i-silicon carbide castable isetyenziselwa i-lining yecandelo lobushushu obuphezulu, elinokumelana notshintsho olukhawulezileyo lobushushu ngexesha lenkqubo yokudubula yesamente kwaye liqinisekise uzinzo lobushushu be-oven, ngaloo ndlela liphucula umgangatho weemveliso zesamente.

3. Ishishini leeKhemikhali: Ukumelana nokugqwala kwiindawo ezinobungozi

Ishishini leekhemikhali libandakanya iintlobo ngeentlobo zezinto ezibangela ukubola (ezifana nee-asidi, ii-alkali, kunye neetyuwa) kunye neenkqubo zokusabela kubushushu obuphezulu. Izixhobo ezifana neekettles zokusabela kubushushu obuphezulu, izixhobo zokutshisa iikhemikhali, kunye neenkqubo zokususa i-flue gas desulfurization zineemfuno eziphezulu kakhulu ekuchaseni ukubola kwezinto ezichasayo. I-Silicon carbide castable inozinzo oluhle kakhulu lweekhemikhali kwaye inokumelana nokubola kwe-asidi ezininzi ezinamandla, ii-alkali, kunye nezinyibilikisi ze-organic. Isetyenziswa kakhulu kwi-lining yemithambo ye-chemical reaction, i-flue ducts, kunye ne-chimney linings. Umzekelo, kwizityalo zamandla zokutshisa inkunkuma, i-flue gas ineentlobo ngeentlobo zeegesi ezibangela ukubola kunye namasuntswana. Ukusetyenziswa kwe-silicon carbide castable kwi-lining ye-flue kunokuthintela ngempumelelo ukubola kunye nokuguguleka, ukuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwenkqubo yonyango lwegesi ye-flue.

4. Ishishini lezaMandla: Ukuxhasa ukuSebenza kakuhle kweZixhobo zoMbane

Kwishishini lamandla, izityalo zamandla ezisebenzisa ubushushu, izityalo zamandla ezisebenzisa i-biomass, kunye nezityalo zamandla ezitshisa inkunkuma zonke zifuna izixhobo ezisebenza kakuhle ukuqinisekisa ukusebenza kakuhle kwezixhobo. Udonga lwamanzi ebhoyila, i-superheater, kunye ne-economizer yezityalo zamandla ezisebenzisa ubushushu zifakwa kwi-flue gas scrub yobushushu obuphezulu kunye nokukrazulwa kothuthu. I-silicon carbide castable isetyenziselwa i-anti-wear lining yala macandelo, enokunciphisa ukukrazuka kodonga lwetyhubhu yebhoyila kwaye yandise ubomi benkonzo yebhoyila. Kwizityalo zamandla ezisebenzisa i-biomass, ngenxa yomxholo ophezulu weentsimbi ze-alkali kwi-biomass fuels, i-furniture lining idla ngokukrazuka ngokulula. I-Silicon carbide castable inokumelana ngempumelelo nokukrazuka kwesinyithi se-alkali, iqinisekisa ukusebenza okuzinzileyo kwexesha elide kwesithando somlilo.
