Okubalulekile:

EyethuI-Cylindrical Crucibleyakhiwe nge-silicon carbide graphite ecindezelwe ngokwe-isostatically, into enikeza ukumelana nezinga lokushisa okuphezulu okukhethekile kanye nokuhamba kahle kokushisa, okuyenza ibe ithuluzi elibalulekile lezinhlelo zokusebenza zokuncibilika kwezimboni.

1. I-Silicon Carbide (SiC): I-Silicon carbide yaziwa ngobulukhuni bayo obukhulu kanye nokumelana okuhle kakhulu nokugqoka nokugqwala. Ingakwazi ukumelana namakhemikhali okushisa aphezulu, inikeza ukuzinza okuphakeme ngisho nangaphansi kokucindezeleka okushisayo, okunciphisa ingozi yokuqhekeka ngesikhathi sokushintsha kwezinga lokushisa okungazelelwe.
2. I-Natural Graphite: I-graphite yemvelo iletha ukusebenza kahle okushisayo, iqinisekisa ukusatshalaliswa kokushisa okusheshayo nokufanayo kulo lonke i-crucible. Ngokungafani nezinsimbi ze-graphite ezisekelwe kubumba zendabuko, i-cylindrical crucible yethu isebenzisa i-graphite yemvelo ehlanzekile, ethuthukisa ukusebenza kahle kokudlulisa ukushisa futhi inciphise ukusetshenziswa kwamandla.
3. I-Isostatic Pressing Technology: I-crucible yakhiwa kusetshenziswa ukucindezela kwe-isostatic okuthuthukisiwe, iqinisekisa ukuminyana okufanayo ngaphandle kwamaphutha angaphakathi noma angaphandle. Lobu buchwepheshe buthuthukisa amandla nokumelana nokuqhekeka kwe-crucible, kunwebe ukuqina kwayo ezindaweni ezishisa kakhulu.

Ukusebenza:

Ukumelana Nokugqwala Okuhle Kakhulu: I-silicon carbide graphite crucibles yethu imelana kakhulu nemiphumela yokugqwala yezinsimbi ezincibilikisiwe namakhemikhali, iqinisekisa ukuzinza nokuphila isikhathi eside kwe-crucible ngesikhathi sokusetshenziswa isikhathi eside. Lokhu kubenza balungele ukuncibilikisa i-aluminium, ithusi, nama-alloys ensimbi ahlukahlukene, kunciphisa ukugcinwa nokushintshwa kwemvamisa.
3. Ukuphila Kwesevisi Eyandisiwe: Ngesakhiwo sayo esiminingi namandla aphezulu, ubude besikhathi se-cylindrical crucible yethu bubude ngokuphindwe izikhathi ezingu-2 kuya kwezingu-5 kunezinsimbi zobumba ze-graphite crucibles. Ukumelana okuphakeme kokuqhekeka nokugqoka kwandisa impilo yokusebenza, kwehlisa isikhathi sokuphumula kanye nezindleko zokushintshwa.
4. I-High Oxidation Resistance: Ukwakheka kwezinto eziklanywe ngokukhethekile kuvimbela ngempumelelo i-oxidation ye-graphite, kunciphisa ukuwohloka kumazinga okushisa aphezulu futhi kunwebe nakakhulu impilo ye-crucible.
5. Amandla Omshini Aphakeme: Ngenxa yenqubo yokucindezela ye-isostatic, i-crucible iqhosha ngamandla emishini akhethekile, igcina ukwakheka kwayo nokuqina ezindaweni ezinezinga lokushisa eliphezulu. Lokhu kuyenza ilungele izinqubo zokuncibilikisa ezidinga umfutho ophezulu kanye nokuzinza kwemishini.

Izinzuzo Zomkhiqizo:

• Izinzuzo Zezinto ezibonakalayo: Ukusetshenziswa kwe-graphite yemvelo kanye ne-silicon carbide kuqinisekisa ukuqhutshwa kokushisa okuphezulu nokumelana nokugqwala, kuhlinzeka ngokusebenza okuhlala njalo ezindaweni ezinokhahlo, ezisezingeni eliphezulu.
• Isakhiwo Sokuminyana Okuphezulu: Ubuchwepheshe bokucindezela be-Isostatic buqeda izikhala zangaphakathi nokuqhekeka, kuthuthukisa kakhulu ukuqina namandla kwe-crucible ngesikhathi sokusetshenziswa okunwetshiwe.
• Ukuzinza Kwezinga Lokushisa Okuphezulu: Iyakwazi ukumelana namazinga okushisa afika ku-1700°C, le crucible ilungele izinqubo ezihlukahlukene zokuncibilikisa nokuphonsa ezihlanganisa izinsimbi nama-alloys.
• Ukusebenza Kahle Kwezamandla: Izakhiwo zayo eziphakeme zokudlulisa ukushisa zinciphisa ukusetshenziswa kukaphethiloli, kuyilapho izinto ezivikela imvelo zinciphisa ukungcoliswa kanye nemfucuza.

Ukukhetha ukusebenza okuphezulu kweCylindrical Crucible yethu ngeke nje kuthuthukise ukusebenza kahle kwakho kokuncibilikisa kodwa kuzonciphisa ukusetshenziswa kwamandla, kunwebe ubude besikhathi semishini, kanye nezindleko zokunakekela eziphansi, ekugcineni kuthuthukise ukusebenza kahle kokukhiqiza.
