Igraphite silicon carbide crucible UBomi bonke: IiFactors and Best Practices

I-graphite ye-silicon carbide crucibles zisetyenziswa ngokubanzi kwiilebhu zobushushu obuphezulu kunye novavanyo lokubola ngenxa yokwakheka kwezinto kunye nokusebenza okuphezulu. Ezi crucibles ubukhulu becala zenziwe ngegraphite, enokumelana nobushushu obuphezulu, ukumelana nokugqwala, amandla oxinzelelo oluhle kunye ne-coefficient ephantsi yokwandiswa kwe-thermal. Nangona kunjalo, ubomi benkonzo ye-Graphite silicon carbide crucibles buchatshazelwa yizinto ezininzi, kubandakanywa indawo yokusebenza, uhlobo lwesampula kunye nobushushu benkonzo. Ngaphantsi kweemeko eziqhelekileyo, ubomi benkonzo ye-graphite silicon carbide crucibleukusuka kwiinyanga ezimbalwa ukuya malunga nonyaka. Ukuthobela iindlela ezichanekileyo zokusebenza kunye nokugcina indawo efanelekileyo kunokwandisa ubomi benkonzo kwaye kuthintele umonakalo ongeyomfuneko.

Ukuze uqinisekise ubomi benkonzo ye-graphite silicon carbide crucible, ukusetyenziswa okuchanekileyo kufuneka kulandelwe. Ngaphambi kokusetyenziswa, jonga i-crucible nawuphi na umonakalo, njengokuqhekeka okanye utshintsho lombala. Iqondo lobushushu utshintsho olukhawulezileyo kufuneka luphetshwe ngexesha lokusetyenziswa ukukhusela uxinzelelo lwe-thermal kunye nokuqhekeka. Ukugqithiswa kwesampulu kwi-crucible kufuneka kugwenywe ukukhusela ukuchithwa kwendawo ngexesha lokwandiswa kwe-thermal. Kwakhona, musa ukusebenzisa izinto ezibukhali okanye izixhobo zesampulu ukunciphisa ukuguga kunye nokwandisa iintanda. Emva kokusetyenziswa, coca i-crucible ngexesha lokususa i-debris kunye ne-relesi dues yeekhemikhali, kwaye ugweme ukupholisa ngokukhawuleza kwiqondo lokushisa.

Isishwankathelo, nangona i-Graphite silicon carbide crucibles inokumelana nokushisa okuphezulu okuphezulu, ubomi babo benkonzo buchatshazelwa yizinto ezininzi, kubandakanywa izinto eziphathekayo, uhlobo lwesampula, indawo engqongileyo kunye neendlela zokusebenza. Ke ngoko, ukusetyenziswa kwezesayensi kunye nokugcinwa kwe-graphite silicon carbide crucibles kubalulekile ekwandiseni ubomi benkonzo ye-graphite silicon carbide crucibles kunye nokuphucula iziphumo zovavanyo.
