izinga lokushisa eliphezulu elincibilika i-molybdenum crucible yesithando somlilo

Incazelo emfushane:

Izinga lokushisa eliphakeme elincibilika i-molybdenum crucible iyisitsha esisetshenziselwa ngokukhethekile izicelo zokushisa okuphezulu, ikakhulukazi ezithandweni nakwezinye izinto zokushisa ukushisa.I-Molybdenum yakhethwa ngenxa yezinga layo eliphezulu lokuncibilika kanye nokumelana nokugqwala, okuyenza ifaneleke ukuphatha izinsimbi ezincibilikisiwe nezinye izinto ezisezingeni eliphezulu.Lawa ma-crucibles avame ukusetshenziswa ezimbonini ezifana ne-metallurgy, yokwenza ingilazi kanye nocwaningo lwezinto ezisezingeni lokushisa eliphezulu.

Iyini i-crucible yokuncibilika kwezinga lokushisa eliphezulu?

I-high-temperature melting crucible iyisitsha esikhethekile esiklanyelwe ukumelana nokushisa okukhulu futhi siqukethe izinto ezisesimweni esincibilikisiwe emazingeni okushisa aphezulu.Lezi zinhlayiya ngokuvamile zenziwe ngezinto ezinamaphoyinti aphezulu okuncibilika kanye nokuzinza okuhle kakhulu kokushisa, njengezinsimbi eziphikisayo ezifana ne-molybdenum ne-tungsten noma izitsha zobumba ezifana ne-alumina noma i-zirconia.Zivame ukusetshenziswa ezinqubweni zezimboni ezifana nokuphonswa kwensimbi, ukukhiqizwa kwengilazi kanye nokucwaninga kwezinto ezisezingeni eliphezulu ezidinga ukuqukathwa kwezinto ezincibilikisiwe emazingeni okushisa aphezulu.Lawa ma-crucibles ayingxenye ebalulekile yezithando zokushisa eziphezulu nezinye izinto zokushisa ukushisa.

Lithini izinga lokushisa lesithando somlilo?

Amazinga okushisa esithando somlilo angahluka kuye ngohlelo oluthile nezinto ezicutshungulwayo.Izithando zomlilo eziphakelayo zenzelwe ukufinyelela emazingeni okushisa aphezulu ukuze zincibilike futhi zicubungule izinto ezingaphakathi kwe-crucible.Izinga lokushisa elibanzi lesithando somlilo eliphehlayo linganwebeka lisuka kumakhulu ambalwa amadigri Celsius liye ngaphezu kuka-1000 degrees Celsius, kuye ngomklamo kanye nokusetshenziswa okuhlosiwe kwesithando somlilo.

Yiziphi izitsha ezinezinga eliphezulu lokuncibilika?

Ama-crucibles ezenziwe ngezinto ezithile anamaphuzu aphezulu okuncibilika futhi afanele ukusetshenziswa ekusetshenzisweni kokushisa okuphezulu.Ezinye izinto ezisetshenziselwa ama-high melting point crucibles zihlanganisa:

1. I-Tungsten: I-Tungsten crucibles inezindawo zokuncibilika eziphakeme kakhulu, ezizenza zifaneleke ukucubungula izinto emazingeni okushisa aphakeme kakhulu, njengasekukhiqizweni kwamakristalu esafire nezinye izinqubo zokushisa okuphezulu.

2. I-Molybdenum: I-Molybdenum crucibles nayo inephoyinti eliphezulu lokuncibilika futhi ivame ukusetshenziswa ekusetshenzisweni okubandakanya izinsimbi ezincibilikisiwe, ukuncibilika kwengilazi, kanye nokucwaninga kwezinto ezisezingeni eliphezulu.

3. I-Alumina (i-aluminium oxide): Ama-alumina crucibles ayaziwa ngokumelana namazinga okushisa aphezulu futhi avame ukusetshenziswa ezindaweni zokusebenza zaselabhorethri nezimboni ezibandakanya izinto ezisezingeni eliphezulu.

4. I-Zirconia: I-Zirconia crucibles ingakwazi ukumelana namazinga okushisa aphezulu futhi isetshenziselwa izinhlelo zokusebenza ezifana nokusakazwa kwensimbi nokucutshungulwa kwezinto ezisezingeni eliphezulu.

Lezi zinto zikhethelwe ukwakhiwa kwe-crucible ngenxa yokukwazi ukumelana nokushisa okukhulu nokugcina ubuqotho besakhiwo emazingeni okushisa aphezulu.
