I-Silicon Carbide Castable: Isixazululo Esiphelele Sezicelo Ezinokushisa Okuphezulu Nokumelana Nokuguguleka

Ekukhiqizweni kwezimboni, amazinga okushisa aphezulu, ukuguguleka kwemishini, kanye nokuguguleka kwamakhemikhali kuyizitha ezinkulu zesikhathi senkonzo yemishini kanye nokusebenza kahle kokukhiqiza. Kungakhathaliseki ukuthi isithando sensimbi, isitofu esijikelezayo sikasimende, noma isitsha sokusabela kwamakhemikhali, ukusebenza kwezinto eziphikisayo kunquma ngqo ukuzinza komugqa wokukhiqiza. Phakathi kwezinto eziningi eziphikisayo,i-silicon carbide ephoswayoIvelele ngokumelana kwayo okumangalisayo nokushisa okuphezulu, ukumelana nokuguguleka, kanye nokumelana nokugqwala, okuba yinto ebalulekile ebaluleke kakhulu emikhakheni ehlukahlukene yezimboni edingeka kakhulu emhlabeni jikelele.

I-silicon carbide castable uhlobo lwezinto ezingabunjiwe ezingaphili kahle ezenziwe nge-silicon carbide (SiC) emsulwa kakhulu njenge-aggregate eyinhloko, ehlanganiswe nezihlanganisi zekhwalithi ephezulu, izithasiselo, namanzi. Inezici zokwakha okulula (ingathululwa, idonswe nge-trowele, noma idlidlizwe ibe yisimo), ikwazi ukuzivumelanisa kahle nezakhiwo eziyinkimbinkimbi, futhi ingakha ulwelwesi oluhlanganisiwe oluqinile nolulinganayo ngemva kokulungiswa nokushiswa. Uma kuqhathaniswa nezitini zendabuko ezingaphili kahle nezinye izinto eziphothiwe, inezinzuzo ezisobala zokusebenza, ezingaxazulula ngempumelelo izinkinga zokuphila isikhathi esifushane kanye nokugcinwa njalo kwezintambo zemishini ezindaweni ezinzima.

Izinkambu Eziyinhloko Zokusetshenziswa Kwe-Silicon Carbide Castable

1. Imboni Yensimbi: Itshe Lesisekelo Lokuncibilikisa Izinga Lokushisa Eliphezulu

Imboni yensimbi ingenye yezimakethe ezinkulu kakhulu zesicelo se-silicon carbide castable. Ezitsheni zomlilo, eziguquliwe, ezitsheni zikagesi ze-arc, nasezitsheni zokuncibilikisa insimbi ezingenayo i-ferrous (ezifana ne-aluminium, ithusi, kanye ne-zinc smelting), izingqimba zibhekana nezimo ezimbi kakhulu njengokushisa okuphezulu (kufika ku-1600℃), ukuguguleka kwensimbi encibilikisiwe, kanye nokukhuhla i-slag yesithando. I-Silicon carbide castable, enezinga layo eliphezulu lokuncibilika (ngaphezu kuka-2700℃) kanye nokumelana okuhle kakhulu nokuguguleka, isetshenziswa kabanzi ezingqimbeni zemilomo yesithando, ama-tapholes, izindawo zokukhipha i-slag, nezinye izingxenye ezibalulekile. Ingamelana ngempumelelo nokuguguleka kwensimbi encibilikisiwe, insimbi, kanye nezinsimbi ezingenayo i-ferrous, inciphise imvamisa yokufakwa esikhundleni kwe-lining, futhi ithuthukise isikhathi sokusebenza esiqhubekayo sesithando. Isibonelo, ezitsheni zokuncibilikisa i-aluminium, i-silicon carbide castable isetshenziselwa ungqimba lwechibi lokuncibilikisa, elingamelana nokugqwala kwe-aluminium encibilikisiwe futhi landise impilo yesevisi yesithando ngaphezu kuka-50% uma kuqhathaniswa nezinto zendabuko.

2. Imboni Yezinto Zokwakha: Ukukhulisa Ukusebenza Kahle Kokukhiqizwa Kwesimende Nobumba

Embonini yezinto zokwakha, ama-oven ajikelezayo esimende, ama-oven ajikelezayo e-ceramic, kanye nama-oven ancibilikisa ingilazi anezidingo eziqinile ezintweni ezivimbela ukugqwala. I-preheater, i-cyclone separator, kanye ne-tertiary air duct yama-oven ajikelezayo esimende zisendaweni eshisa kakhulu, enothuli, kanye nokuguguleka kwegesi isikhathi eside. Ukusetshenziswa kwe-silicon carbide castable njenge-lining akugcini nje ngokumelana nokuguquguquka kokushisa okuphezulu kodwa futhi kuvimbela ngempumelelo ukukhuhla nokuklwebheka kwe-clinker kanye nothuli lwe-cement. Lokhu kunciphisa izindleko zokugcinwa kwesistimu ye-oven futhi kuthuthukisa ukusebenza kahle kwe-cement. Kuma-oven ajikelezayo e-ceramic, i-silicon carbide castable isetshenziselwa i-lining yesigaba sokushisa okuphezulu, esingazivumelanisa nokushintsha okusheshayo kokushisa ngesikhathi senqubo yokudubula kwe-ceramic futhi siqinisekise ukuzinza kokushisa kwe-oven, ngaleyo ndlela kuthuthukiswe ikhwalithi yemikhiqizo ye-ceramic.

3. Imboni Yamakhemikhali: Ukumelana Nokugqwala Ezindaweni Ezinzima

Imboni yamakhemikhali ihilela izinhlobo ezahlukene zezinto ezigqwalisayo (ezifana nama-asidi, ama-alkali, nosawoti) kanye nezinqubo zokusabela ezishisa kakhulu. Imishini efana nama-kettle okusabela ashisa kakhulu, izinto zokushisa zamakhemikhali, kanye nezinhlelo zokususa i-flue gas desulfurization inezidingo eziphezulu kakhulu ekumelaneni nokugqwala kwezinto eziphikisayo. I-Silicon carbide castable inokuqina okuhle kwamakhemikhali futhi ingamelana nokuguguleka kwama-asidi amaningi aqinile, ama-alkali, kanye nezinyibilikisi eziphilayo. Isetshenziswa kabanzi elangeni lemikhumbi yokusabela kwamakhemikhali, amapayipi okuhambisa uketshezi, kanye nama-chimney linings. Isibonelo, ezitshalweni zamandla okushisa udoti, igesi yokuhambisa uketshezi iqukethe izinhlobo ezahlukene zamagesi agqwalisayo kanye nezinhlayiya. Ukusetshenziswa kwe-silicon carbide castable elangeni lokuhambisa uketshezi kungavimbela ngempumelelo ukugqwala nokuguguleka, kuqinisekiswe ukusebenza okuphephile nokuzinzile kohlelo lokwelapha igesi yokuhambisa uketshezi.

4. Imboni Yamandla: Ukusekela Ukusebenza Kahle Kwemishini Yamandla

Embonini yamandla, izitshalo zamandla ezishisayo, izitshalo zamandla ezisebenzisa i-biomass, kanye nezitshalo zamandla ezishisa imfucuza zonke zidinga izinto ezisebenza kahle ukuqinisekisa ukusebenza kahle kwemishini. Udonga lwamanzi ebhoyila, i-superheater, kanye ne-economizer yezitshalo zamandla ezishisayo zihlushwa yigesi yokushisa ephezulu kanye nokuhuzuka komlotha. I-Silicon carbide castable isetshenziselwa ulwelwesi oluvimbela ukuguguleka kwalezi zingxenye, okunganciphisa ukuguguleka kodonga lweshubhu lebhoyila futhi kwandise impilo yesevisi yebhoyila. Ezitshalweni zamandla ezisebenzisa i-biomass, ngenxa yokuqukethwe okuphezulu kwezinsimbi ze-alkali kumafutha e-biomass, ulwelwesi lwesithando luyaguguleka kalula. I-Silicon carbide castable ingamelana ngempumelelo nokugqwala kwensimbi ye-alkali, iqinisekise ukusebenza okuzinzile kwesikhathi eside kwesithando.
