Ezweni elikhulu lokukhiqiza kwezimboni, izixhumanisi eziningi ezibalulekile azikwazi ukwenza ngaphandle kokusekelwa kwezinto ezisebenza kahle kakhulu. Namuhla, sizokwethula izinto ezidlala indima ebalulekile ezimbonini zendabuko ezifana nama-oven kanye nezinhlelo zokususa i-sulfurization -i-silicon carbide ceramics ephendukile.
Kuyini i-silicon carbide ceramic?
I-silicon carbide ceramic iyinto esezingeni eliphezulu ye-ceramic eyakhiwe nge-silicon ne-carbon. Akuyona i-ceramic evamile, kodwa "i-metamaterial" enezakhiwo eziningi ezinhle kakhulu. Inezici zamandla okushisa aphezulu, ukumelana nokuguguleka okuhle, i-coefficient ephansi yokwanda kokushisa, ubulukhuni obuphezulu, kanye nokumelana nokugqwala kwamakhemikhali, okwenza ivelele phakathi kwezinto eziningi.
Ama-ceramic e-silicon carbide ahlanganisiwe ayindlela ekhethekile yama-ceramic e-silicon carbide, futhi inqubo yawo yokulungiselela ihlukile kakhulu - okokuqala, izinhlayiya ezincane ze-alpha SiC kanye nezithasiselo zicindezelwa emzimbeni oluhlaza, bese zixhunyaniswa ne-silicon ewuketshezi ekushiseni okuphezulu. Kuleli qophelo, ikhabhoni engenalutho idlula ekusabeleni kwamakhemikhali okumangalisayo ne-Si engenile, ikhiqiza i-β – SiC futhi iboshwe ngokuqinile ne-α – SiC. Ngesikhathi esifanayo, i-silicon yamahhala igcwalisa ama-pores, ekugcineni ithole izinto ze-ceramic ezixinene kakhulu.
Itshe legumbi esithandweni somlilo
Ukushiswa kwe-reaction kwe-silicon carbide ceramics kuyindima ebalulekile futhi ebalulekile kuma-oven ahlukahlukene anokushisa okuphezulu. Isibonelo, kuma-oven okukhiqiza i-ceramic afana nama-oven roller, ama-oven tunnel, ama-oven shuttle, njll., kwenziwa izingxenye ezibalulekile njengemikhono ye-nozzle, ama-crossbeam rollers, namapayipi omoya obandayo.
Isivikelo se-flame nozzle singalawula ngempumelelo ibhalansi yokushisa ngaphakathi kwesitofu. Sinezici zamandla okushisa aphezulu, ukumelana nokushiswa kwe-oxidation, ukumelana nokuguguleka, kanye nokumelana nokupholisa nokushisa okusheshayo. Ngeke kuphuke noma kuguquke ngemva kokusetshenziswa kwezinga lokushisa eliphakeme isikhathi eside, okuqinisekisa indawo yokushisa ezinzile esitofu. Kubalulekile ekushiseni imikhiqizo ye-ceramic esezingeni eliphezulu.
Ama-crossbeam rollers kanye nama-cold air ducts ngokulandelana anemithwalo yemfanelo ebalulekile yokusekela kanye nokungenisa umoya. I-crossbeam roller inezici zokuqina okuhle kokushisa, ukumelana nokushiswa kwe-oxidation, kanye nokumelana nokukhukhuleka kwezinga lokushisa eliphezulu. Akulula ukuguquguqula nokugoba ngemva kokusetshenziswa isikhathi eside emazingeni okushisa aphezulu, ukuqinisekisa ukuqina kwesakhiwo sangaphakathi sesithando kanye nokuthuthwa kwezinto ezibushelelezi. I-cold air duct inesibopho sokulawula ukugeleza kwegesi kanye nokusatshalaliswa kwezinga lokushisa ngaphakathi kwesithando, ukuqinisekisa ukusebenza okuvamile kwesithando.
Ngokombono wezingxenye ezenziwe ngokwezifiso, i-reaction sintered silicon carbide inezinzuzo ezisobala ekukhiqizweni kwezingxenye ze-oven. Ngenxa yobukhulu bayo obungashintshi ngaphambi nangemva kokusikwa, ingacutshungulwa ibe yinoma yisiphi isimo nosayizi ngemva kokubumba. Abakhiqizi be-oven bangenza ngokwezifiso izimo ezahlukene kanye nemininingwane yezingxenye ngokuya ngemiklamo ehlukene ye-oven kanye nezidingo zokukhiqiza, bahlangabezane nezidingo zokukhiqiza zemikhiqizo emikhulu neyinkimbinkimbi, okunzima ngezinye izinto ukuyifeza.
Umugqa wokuzivikela oqinile wesistimu yokususa i-sulfurization
Emkhakheni wokuvikelwa kwemvelo njengokususwa kwesibabule ezitshalweni zamandla, izitsha ze-silicon carbide ezisabelayo nazo zidlala indima ebalulekile, ikakhulukazi esicini esiyinhloko sama-nozzles okususwa kwesibabule. Igesi yomoya ekhishwa ezitshalweni zamandla iqukethe inani elikhulu lokungcola njenge-sulfur dioxide, kanti ama-nozzles okususwa kwesibabule angamathuluzi abalulekile okususa lokhu kungcola.
I-nozzle ye-silicon carbide desulfurization yokusabela inezici ezinhle kakhulu njengamandla aphezulu, ubulukhuni obuphezulu, ukumelana nokugqwala okunamandla, ukumelana nokuguguleka, kanye nokumelana nokushisa okuphezulu. Inempilo yenkonzo engavamile ngaphansi kwezimo ezinzima, okungenakuqhathaniswa nezinto ezivamile. Izinhlobo ezivame ukusetshenziswa zama-nozzle e-desulfurization zifaka ama-nozzle ajikelezayo nama-nozzle e-vortex, anemiklamo ehlukene kanye nezimiso zokusebenza, kodwa angenza i-desulfurizer ibe yi-atomu ngempumelelo futhi ayithinte ngokugcwele negesi yomoya, ngaleyo ndlela athole umphumela omuhle we-desulfurization.
Ngomklamo oyingqayizivele wesakhiwo, i-spiral nozzle yenza uketshezi olusengqimbeni engaphandle lushaye ubuso obujikelezayo nge-engeli ethile ku-nozzle, lushintshe indlela yokufafaza bese lushiya i-nozzle, lwakha insimu yenkungu eqinile, enganikeza ama-engeli ahlukahlukene okufafaza, futhi isenamandla aphezulu okumunca ngaphansi kwengcindezi ephansi kakhulu. I-vortex nozzle ivumela i-slurry ukuthi ingene ekamelweni elijikelezayo le-nozzle isuka ohlangothini oluqondile, bese ikhipha kusuka endaweni engezansi ngama-engeli angakwesokudla iye ohlangothini lokungena. I-spray incane futhi iyafana, kanti isiteshi se-vortex sikhulu, okungelula ukuyivimba.
Ezingxenyeni ezenziwe ngokwezifiso zezinhlelo zokususa i-sulfurization, i-silicon carbide e-reaction sintered ingenza ngokwezifiso ukuma kwe-nozzle, usayizi, kanye nezici zokufafaza ezifanele kakhulu ngokuya ngezinqubo ezahlukene zokususa i-sulfurization, amazinga okugeleza kwegesi yomoya, amazinga okugxila, kanye neminye imingcele, ukuqinisekisa ukusebenza okuphumelelayo nokuzinzile kohlelo lokususa i-sulfurization kanye nokuhlangabezana nezidingo zemvelo eziqinile.
Izitsha zobumba ze-silicon carbide ezisebenza ngokusabela zidlala indima engenakuphikwa emikhakheni yezimboni yendabuko efana nama-oven kanye nezinhlelo zokususa i-sulfurization ngenxa yezakhiwo zazo ezihlukile kanye nezinzuzo ezingenziwa ngokwezifiso. Zinikeza isiqinisekiso esiqinile sokusebenza kahle, okuzinzile, nokunobungani nemvelo komkhiqizo wezimboni futhi zifaka ugqozi oluqinile ekuthuthukisweni kwezobuchwepheshe kanye nentuthuko yezimboni zendabuko.
