Kungani sidinga i-graphite ensimini yokushisa yesithando sekristalu esisodwa

Uhlelo lokushisa lwesithando sekristalu elilodwa eliqondile lubizwa nangokuthi insimu yokushisa. Umsebenzi wohlelo lwensimu yokushisa ye-graphite ubhekisela ohlelweni lonke lokuncibilikisa izinto ze-silicon nokugcina ukukhula kwekristalu elilodwa ekushiseni okuthile. Kalula nje, lupheleleuhlelo lokushisa lwe-graphiteyokudonsa i-silicon eyodwa yekristalu.

Insimu yokushisa ye-graphite ngokuvamile ihlanganisa(izinto zegrafiti) indandatho yokucindezela, isembozo sokuvikela ukushisa, isembozo sokuvikela ukushisa esiphezulu, esiphakathi nesingaphansi,isitsha sokubethela se-graphite(i-crucible enamapetali amathathu), induku yokusekela i-crucible, ithreyi ye-crucible, i-electrode, i-heater,ithubhu lokuqondisa, i-graphite bolt, futhi ukuze kuvinjelwe ukuvuza kwe-silicon, iphansi lesithando, i-electrode yensimbi, induku yokusekela, konke kufakwe amapuleti okuvikela kanye nezembozo zokuvikela.

Kunezizathu eziningana eziyinhloko zokusebenzisa ama-electrode e-graphite ensimini yokushisa:

Ukuqhuba kahle kakhulu

I-Graphite inomoya omuhle kagesi futhi ingaqhuba kahle ugesi ensimini yokushisa. Lapho insimu yokushisa isebenza, ugesi onamandla udinga ukungeniswa nge-electrode ukuze kukhiqizwe ukushisa. I-electrode ye-graphite ingaqinisekisa ukuthi ugesi udlula kahle, inciphise ukulahleka kwamandla, futhi yenze insimu yokushisa ishise ngokushesha futhi ifinyelele izinga lokushisa lokusebenza elidingekayo. Ungacabanga ukuthi, njengokusebenzisa izintambo zekhwalithi ephezulu kusekethe, ama-electrode e-graphite anganikeza isiteshi samandla esingavimbelwe sensimu yokushisa ukuqinisekisa ukusebenza okuvamile kwensimu yokushisa.

Ukumelana nokushisa okuphezulu

Insimu yokushisa ivame ukusebenza endaweni enokushisa okuphezulu, futhi i-graphite electrode ingamelana namazinga okushisa aphezulu kakhulu. Indawo yokuncibilika kwe-graphite iphakeme kakhulu, ngokuvamile ingaphezu kuka-3000℃, okwenza ikwazi ukugcina isakhiwo esizinzile kanye nokusebenza kahle ensimini yokushisa ephezulu, futhi ngeke ithambise, ishintshe noma incibilike ngenxa yokushisa okuphezulu. Ngisho nangaphansi kwezimo zokusebenza zesikhathi eside ezinokushisa okuphezulu, i-graphite electrode ingasebenza ngokuthembekile futhi ihlinzeke ngokushisa okuqhubekayo kwensimu yokushisa.

Ukuqina kwamakhemikhali

I-Graphite inamandla amahle okuqina kwamakhemikhali emazingeni okushisa aphezulu futhi akulula ukusabela ngamakhemikhali nezinye izinto ensimini yokushisa. Ensimini yokushisa, kungase kube namagesi ahlukahlukene, izinsimbi ezincibilikisiwe noma amanye amakhemikhali, futhi i-electrode ye-graphite ingamelana nokuguguleka kwalezi zinto futhi igcine ubuqotho bayo nokusebenza kwayo. Lokhu kuzinza kwamakhemikhali kuqinisekisa ukusetshenziswa kwesikhathi eside kwama-electrode e-graphite ensimini yokushisa futhi kunciphisa umonakalo kanye nemvamisa yokufakwa esikhundleni kwama-electrode okubangelwa ukusabela kwamakhemikhali.

Amandla omshini

Ama-electrode e-graphite anamandla athile okusebenza futhi angamelana nokucindezeleka okuhlukahlukene ensimini yokushisa. Ngesikhathi sokufakwa, ukusetshenziswa nokugcinwa kwensimu yokushisa, ama-electrode angase abhekane namandla angaphandle, njengamandla okubopha ngesikhathi sokufakwa, ukucindezeleka okubangelwa ukwanda kokushisa, njll. Amandla okusebenza e-electrode ye-graphite ayenza ikwazi ukuhlala izinzile ngaphansi kwalezi zingcindezi futhi akulula ukuphula noma ukulimaza.

Ukusebenza kahle kwezindleko

Ngokombono wezindleko, ama-electrode e-graphite ayonga kakhulu. I-Graphite iyinsiza yemvelo eningi enezindleko zokumba nokucubungula eziphansi. Ngesikhathi esifanayo, ama-electrode e-graphite anempilo ende yesevisi kanye nokusebenza okuthembekile, okunciphisa izindleko zokushintsha ama-electrode njalo. Ngakho-ke, ukusetshenziswa kwama-electrode e-graphite ezindaweni zokushisa kunganciphisa izindleko zokukhiqiza ngenkathi kuqinisekiswa ukusebenza kahle.
