Silicon carbide esithandweni somliloinamandla amakhulu, ukuqina okuphezulu, ukumelana nokugqokwa okuhle, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nokushisa okuhle nokumelana nokushaqeka, ukuguquguquka okukhulu kwe-thermal, ukumelana okuhle kwe-oxidation neminye imisebenzi emihle kakhulu, ikakhulukazi esetshenziswa ekubunjweni kwamafrikhwensi aphakathi, isithando somlilo esihlukahlukene sokushisa, i-metallurgy. , imboni yamakhemikhali, ukuzivocavoca kwensimbi okungeyona insimbi neminye imisebenzi.
Izici zeamashubhu omlilo we-silicon carbide
Silicon carbide esithandweni somliloI-silicon carbide njengento eluhlaza eyinhloko, enhle kakhuluimikhiqizo ye-silicon carbideokwenziwe ukushisa okuphezulu kokushisa, ukumelana nokushisa okuphezulu, ukuguquguquka kwe-thermal okusheshayo, amandla aphezulu, ubulukhuni obukhulu, ukumelana nokugqoka okuhle, ukumelana nokushisa okuhle nokumelana nokuzamazama komhlaba, ukuguquguquka okuhle kokushisa, ukumelana okuhle kwe-oxidation neminye imisebenzi emihle kakhulu emikhawulweni yomibili yokufakwa Isembozo esikhethekile sokushisa okuphezulu. Ingakwazi ukugwema ngokuphumelelayo ukugqwala kwesisombululo sensimbi ezintweni zokushisa zikagesi (okuhlanganisa izinduku ze-silicon, izintambo zikagesi zokufudumeza isithando somlilo, njll.), kanye nokusetshenziswa okuyinhloko kwamashubhu okuvikela e-silicon carbide anezinkomba ezihlukahlukene ezingcono kunemikhiqizo ehlukahlukene ye-graphite ine-conductivity eshisayo, ukumelana ne-oxidation, ukumelana nokushaqeka kokushisa, nokumelana nokushisa okuphezulu
Ubuchwepheshe bokukhiqiza be-silicon carbide furnace tube
Umkhiqizo uyi-silicon carbide njengento eyinhloko eluhlaza, ngenqubo ekhethekile yokushisa okuphezulu okugazingiwa kwemikhiqizo emihle kakhulu ye-silicon carbide, izinga lobude lingenziwa ngokwezifiso ngokuvumelana nezidingo zangempela zamakhasimende.
Ukusetshenziswa kokuqala kweamashubhu omlilo we-silicon carbide
Isetshenziswa kakhulu ekuqeqesheni insimbi engeyona ayoni, imikhiqizo ye-aluminium ye-degassing system, imishini yokunyathelisa nokudaya, ukuqeqeshwa kwe-zinc ne-aluminium kanye nokucubungula umkhiqizo kanye neminye imisebenzi.
Ukuthuthukiswa kwezimboni ze-silicon carbide furnace tube
Ishubhu ye-silicon carbide furnace inezici zokungaphumeleli okokufaka okuphezulu, umsindo ophansi, ukuhleleka okuhle, njll. Ingenye yamadivayisi athuthuka ngokushesha e-silicon carbide njengamanje, futhi isithengiselwe kuqala. Uma kuqhathaniswa nezingxenye ze-MOSFET, izingxenye ze-JFET azinazo izinkinga zokwethenjelwa ezibangelwa ukukhubazeka kwengqimba ye-oksijini yesango kanye nomkhawulo wokuhamba kwenkampani yenethiwekhi ephansi, futhi zigcina amandla okusebenza okuhle kwemvamisa ephezulu ngenxa yezimpawu zokusebenza kwe-unipolar. Ngaphezu kwalokho, amadivayisi we-JFET anokuqina okuhle kokusebenza nokuthembeka emazingeni okushisa aphezulu. Ngenxa yesakhiwo se-electrode yesango le-silicon carbide JFET device, i-threshold voltage ye-JFET ivamise ukuba yi-negative, okungukuthi, kukhona amadivaysi avamile, angalungile kakhulu ekusetshenzisweni kwawo emkhakheni we-electronics yamandla, futhi akuhambisani nomjikelezo wamanje we-universal drive. Ngokwethula ubuchwepheshe bedivayisi bomjovo we-groove noma isakhiwo se-mesa groove, idivayisi ethuthukisiwe enesimo esivamile sokusebenza iyathuthukiswa. Kodwa-ke, njengoba amadivaysi athuthukisiwe akhiwa kakhulu ngezindleko zezimpawu ezithile zokumelana ne-front-end, kulula ukufeza ukuminyana kwamandla aphezulu kanye nomthamo wamanje we-JFET-break-break (uhlobo lokuncipha) kanye nendlela yokuxhuma ukuncipha. thayipha amadivayisi we-JFET ochungechungeni olungaphezulu lwe-cascade kufinyelelwa ngokuxhuma ama-MOSFET ekilasi le-Si ane-voltage ephansi ochungechungeni. Umjikelezo wedrayivu wedivayisi ye-JFET ye-cascade iyahambisana ngokwemvelo nesekethe yedrayivu yedivayisi ye-silicon yenhloso evamile. Isakhiwo se-cascade sifaneleka kakhulu ku-voltage ephezulu kanye nezimo zokukhipha okuphezulu, kunokuba kusetshenziswe amadivayisi we-silicon ye-IGBT yendabuko, ukugwema ngokuqondile inkinga yokuhambisana yesekethe yedrayivu.
Izinzuzo ze-silicon carbide zimi kanje.
I-1, umsebenzi wokudlulisa ukushisa muhle, udonga lwe-tube luncane (amamilimitha ambalwa kuphela), impendulo yokushintsha izinga lokushisa lomkhiqizo ifudumele kakhulu;
2, akuthintwa ukugqwala
3, izinga lokushisa eliphezulu alincibiliki, i-metal liquid pollution-free;
4, ingasetshenziswa ukuncibilikisa ingxubevange ye-sodium ne-strontium ecebile;
5, ukubukeka komkhiqizo akunamathiselwe ku-slag, ukuvikela kulula kakhulu;
6, izinga lokushisa eliphezulu ukumelana 1600;
7. Ukumelana nokushaqeka okushisayo okunamandla
8, ubulukhuni obukhulu, akulula ukuphuka
9 Ibiza kakhulu, impilo esikhathini esingaphezu kwesigamu sonyaka.
Okungenhla yizici zokusebenza ze-silicon carbide furnace tube, uma udinga ukwazi okwengeziwe, ungazizwa ukhululekile ukuxhumana nathi!
