1.Tarisa kuramba kwesilicon carbide kudziyisa chinhu mune imwechete batch usati wavhura kurongedza, isa yepedyo kuramba muchikamu chimwe chete, izvo zvinoita kuti tembiricha tembiricha iwedzere yunifomu, iko kuramba kwatinonyora munzvimbo inotonhora.

2.Nekuti nesilicon carbide yakaoma uye yakapwanyika zvinhu, usayedze kugadzirisa kana iwe uchiisa, ita kuti igone kutakurika sezvinobvira, zvinoreva kuigadzira uye inogona kubuda nyore mushure mekuisa. Iyo silicon carbide yekudziya chinhu inogona kuisa ne dangle kana flat.

3.Iyo silicon carbide yekudziya element controller inoshandisa thyristor kutonga, saka simba rinogadzirika, iro rakatemwa simba remutongi rinofanirwa kunge rakapetwa katatu pane iro rakatarwa simba rechoto, nekudaro ichiwedzera iyo silicon carbide yekupisa yehupenyu hupenyu, ichishandisa nenzira iri nani.

4.Sarudza iyo inonzwisisika wiring nzira inoenderana nesaizi uye kuramba kwesilicon carbide kudziyisa chinhu.

5.Iyo nyowani yesilicon carbide yekudziya chinhu inofanirwa kuwedzera simba zvishoma nezvishoma mukupisa, ita musiyano pakati pesilicon carbide yekudziya element tembiricha uye tembiricha tembiricha ishoma, nokudaro ichiwedzera iyo silicon carbide yekupisa element life. mushure mekuisa iyo silicon carbide yekupisa element, kufambisa kwesimba nenzira inotevera: Chekutanga isa simba ku30% -40% yesimba rekugadzira kuti preheat maminetsi makumi maviri -40 maminetsi, ndokuwedzera kusvika pa60% -70% yesimba rekugadzira kuita incubation20 maminetsi -30 maminetsi, mushure iyo tembiricha yesilicon carbide yekupisa element uye chirahwe zvakaenzana, wobva wawedzera simba zvishoma nezvishoma, yakanyorwa voltage uye yazvino kudzamara tembiricha yasvika kune tembiricha yaunoda, iyi ndiyo yakajairwa kushandisa magetsi uye yazvino yesilicon carbide yekudziya chinhu, Mukati meiyi nharaunda inogona kuiswa kune otomatiki tembiricha kudzora, apo kuramba kwakava kukuru kuwedzera iwo voltage yakakodzera, kugadzira iyo silicon carbide yekupisa element kune maintai n simba rakatsiga

6. Mushure mekuvira kwechoto, apo iyo silicon carbide yekudziya element inotidziisa isu kuisa tafura seinotevera: Kana simba rekutumira rikaiswa kutanga kushandisa 40% simba reyakajairwa simba, kupisa maminetsi makumi maviri, wobva wawedzera tembiricha kune tembiricha yaunoda. kwemaminitsi gumi kusvika pamaminitsi makumi matatu, uye wozoisa nguva yekubata.

7.Do kwete kungo tarisa iyo voltage kana yazvino mukufamba kwekushandisa silicon carbide kudziyisa chinhu, nekuti kana iwe ukashandisa iyo kuramba ichave yakakura zvishoma nezvishoma (iyo voltage ichave yakakura uye yazvino ichave iri diki), kana iyo yekuisa simba ichigara, ipapo tembiricha inogara iripo.

8.Kana iyo silicon carbide yekudziya chinhu ikakuvara mushure mekushandisa mwedzi, usashandure imwe nyowani, shandura yechinhu chakashandiswa chesilicon carbide kudziisa chinhu, ndizvozvo nekuti kuramba kuchakura kana kuchishandiswa, kushorwa kweiyo nyowani kuchaita. ive diki, kana iwe ukashandisa iyo nyowani tembiricha ichave yakasiyana neyakashandiswa yesilicon carbide yekudziya chinhu, kuti iwe ugone kushandura iyo yakashandiswa, izvo zvinoita kuti kuramba kwemidziyo yekudziya kuve pedyo. zvinhu, ndokumbira uchinje zvese zvinopisa zvive zvitsva, ipapo iyo yawakashandisa iwe yaunogona kuchinja kana uchinge waida.

9.Kushora kuchave kwakakura kana uchishandisa chinhu chekudziya, kana tembiricha isingakwanise kugutsikana kana magetsi asvika pakakwirira, ndapota chinja kubatana, kwakadai senge kubatanidza mune dzakateedzana kunogona kuchinja kuenderana, nyeredzi kubatanidza shanduko kune delta yekubatanidza, iwe inofanira kuchinja chinongedzo zvinoenderana nemutongi wako

10.Iyo simbi oxide uye slag nezvimwe zvinhu muvira zvinofanirwa kucheneswa munguva, usazvichengetera muvira, kana zvikabatanidza chinhu chinopisa kuti chikanganise.

11.Kuramba uchishandisa kushandisa kuchave nehupenyu hwakareba kupfuura kupindirana kwekushandisa.

12.Zvaunoda kudziirwa hazvifanirwe kunge zvine hunyoro hwakanyanya, kuitira kudzivirira chinhu chinopisa kupisa, edza kudzivirira kusangana kwakanangana nezvinhu zvine alkaline.

13. Iyo tembiricha yesilicon carbide yekupisa element pamusoro haifanirwe kupfuura 1550 ℃.

SICTECH Silicon carbide yekudziya zvinhu zvinowanzoenderana nekushomeka kweiyo oxidation, kuumbwa kweSilica uye kuwedzera kwemagetsi kuramba, kunodaidzwa kunzi kuora kuri kushandiswa.Iyi oxidation reaction inoratidzwa mune inotevera fomula.

SiC + 2O2 → SiO2 + CO2

Silicon carbide (SiC) inopindirana neoksijeni (O2) mumhepo uye pamusoro pezvinhu zvinopisa zvishoma nezvishoma oxides, ichiumba Silica (SiO2), inova insulator, nepo huwandu hwayo huchiwedzera. Izvi zvinomutsa kuramba kwemagetsi. Oxidation inoitika kana tembiricha ichisvika 800 ° C uye ichikurumidzirwa sezvo tembiricha inowedzera. Rapid oxidation ichaitika mune yekutanga nhanho yekushandisa, asi iwo mwero weiyo oxidation unodzikira zvishoma nezvishoma. muganho wehupenyu hwebasa unofungidzirwa kuve kana kushomeka kwayo kuchikwira kusvika panenge katatu nguva kuramba kwekutanga.
