Kungani Usebenzisana Nathi?

Uma usikhetha, uthola okungaphezu komkhiqizo—uthola uzakwethu.

• Ubuchwepheshe: Amashumi eminyaka yesipiliyoni embonini yokusungula.
• Ukwenza ngokwezifiso: Izixazululo ezenzelwe ukuhlangabezana nezidingo zakho ezithile.
• Ukusekela: Kusukela ekukhethweni kuya ekufakweni, sinawe kuzo zonke izinyathelo zendlela.

I-Carbon Crucible amaqhawe angaqanjwanga wokulingisa insimbi. Eqinisweni, badlala indima ebalulekile ekusingatheni ezinye zezinselele zokuncibilika ezinzima kuma-foundries nasezindaweni ezinezinga lokushisa eliphezulu. Ubuwazi yini ukuthi lezi zinsimbi zikwazi ukumelana namazinga okushisa angaphezu kuka-1600°C? Akuyona into encane leyo! Ukuqina kwazo, kuhlanganiswe ne-thermal conductivity ehlukile, kuzenza zibaluleke kakhulu emhlabeni wensimbi.

1. Izici ezibalulekile zeUkuncibilika kwe-Metal Crucibles

• Ukumelana Nokushisa Okuphezulu: Idizayinelwe ukumelana namazinga okushisa aphakeme, izinsimbi ezincibilikayo zensimbi zenzelwe ukusingatha izidingo zezinsimbi ezihlukahlukene, ukuqinisekisa ukuphepha nokusebenza kahle.
• I-Thermal Conductivity Enhle Kakhulu: Izinto ezisetshenziswayo zikhuthaza ukusatshalaliswa kokushisa okusheshayo nokufana okufanayo, ukunciphisa izikhathi zokuncibilika nokusetshenziswa kwamandla.
• Ukumelana Nokugqwala: Ngezinto ezisetshenziswayo ezimelana ne-oxidation nokuhlaselwa kwamakhemikhali, lezi zinhlayiya zinwebe izimpilo zesevisi, okusho ukuthi ukonga izindleko ngokuhamba kwesikhathi.
• I-Coefficient Ephansi Yokunwetshwa Kwe-Thermal: Lesi sici sinciphisa ingozi yokuqhekeka phakathi nokuhamba ngebhayisikili okushisayo, iqinisekisa ukwethembeka kwinqubo yokuncibilika.
• I-Smooth Inner Wall: Lesi sici somklamo sivimbela insimbi ekubambeleleni endaweni ebhobokayo, yenze kube lula ukuthululwa nokuhlanza.2. Izinketho Zezinto Zokuncibilikisa Izinsimbi Zensimbi
  Lapho ukhetha i-crucible yensimbi encibilikayo, cabanga ngezinto ezilandelayo:
  • I-Silicon Carbide Graphite: Le nto inikezela nge-thermal conductivity ehlukile futhi imelana kakhulu nokushaqeka okushisayo, ikwenze ilungele ukusetshenziswa okunokushisa okuphezulu. Isebenza kahle kakhulu ezindaweni zokuncibilika kokungeniswa.
  • I-Clay Graphite: Eyaziwa ngokuhlala kwayo nokusebenza kahle kwezindleko, izinsimbi ze-clay graphite zifanele ukuncibilika kwenhloso evamile. Bahlinzeka nge-conductivity enhle yokushisa futhi bavame ukusetshenziswa emisebenzini yendabuko yesisekelo.
  • I-Graphite Ehlanzekile: Idume ngokusebenza kwayo okuhle kakhulu kwe-thermal kanye nogesi, ama-graphite crucibles ahlanzekile alungele izinhlelo zokusebenza ezidinga ukunemba okuphezulu kanye nokungcoliswa okuncane. Zihamba phambili ezindaweni ezinezinga eliphezulu lokushisa futhi ziwusizo ikakhulukazi ezinsimbi eziyigugu.

  3. Ukuhambisana Nezinhlobo Zesithando
  Izinsimbi zensimbi ezincibilikayo zinemisebenzi eminingi futhi zingasetshenziswa ezinhlotsheni ezahlukahlukene zesithando somlilo, okuhlanganisa:

  • Ama-Induction Furnaces: Alungele ukulawula okunembile kwamazinga okushisa ancibilikayo, awenze afanelekele ukusakazwa kwensimbi kwekhwalithi ephezulu.
  • Amafurnace Okumelana: Lezi ziko zinikeza izindawo ezizinzile, ezibalulekile ekuncibilikeni okungaguquki.
  • Ama-vacuum Furnaces: Ibalulekile ezintweni ezibucayi, lezi ziko zinciphisa ubungozi be-oxidation kanye nokungcola.
