izinga lokushisa eliphezulu le-tungsten alloy pot crucible for laboratory

izinga lokushisa eliphezulu le-tungsten alloy encibilikayo ibhodwe crucible for laboratory Isithombe esifakiwe

Incazelo emfushane:

Ukushisa okuphezulu kwe-tungsten alloy furnace crucible kuyisitsha esikhethekile esisetshenziselwa ukuncibilika futhi siqukethe izinto emazingeni okushisa aphakeme kakhulu.Ama-alloys e-Tungsten avame ukukhethwa ama-crucibles ngenxa yephuzu lawo eliphakeme lokuncibilika, ukuqhutshwa kokushisa okuhle kakhulu kanye nokumelana nokuhlaselwa kwamakhemikhali.

Ingakanani izinga lokushisa eliphezulu le-tungsten crucible?

Ukushisa okuphezulu kwe-tungsten crucible kuncike ezintweni ezithile ze-tungsten alloy kanye nenqubo yokukhiqiza.Ngokuvamile, ama-tungsten crucibles angakwazi ukumelana namazinga okushisa angaphezu kuka-3000°C (5432°F), okuwenza afanelekele ukucubungula izinto ezidinga izinga lokushisa eliphezulu kakhulu, njengokuncibilika nokujikijelwa kwezinsimbi, izitsha zobumba, nezinye izinga lokushisa eliphezulu. izinto zokwakha.Kodwa-ke, ukwakheka kwengxubevange ethile kanye nokusebenzisana okungase kube khona nokokusebenza okucutshungulwayo kudinga ukucatshangelwa ukuze kuqinisekiswe ukusebenza okuqinile ngaphezu kwebanga lokushisa elilindelekile.

Ungakwazi yini ukusebenzisa i-crucible efanayo ezinsimbi ezahlukene?

Yebo, ama-tungsten crucibles angasetshenziswa ngezinsimbi ezahlukene, kodwa kubalulekile ukucabangela ukuhambisana kwe-crucible material nensimbi ethize ecutshungulwayo.Ama-Tungsten crucibles avame ukukhethwa ngenxa yokumelana kwawo namazinga okushisa aphezulu kanye nokugqwala kwamakhemikhali, okuwenza afanelekele ukuncibilika kwensimbi okuhlukahlukene nokucubungula izinhlelo zokusebenza.Kodwa-ke, izinsimbi ezithile noma ama-alloys ensimbi angase abe nokusebenzisana okuthile nokokusebenza okuphehlayo, njengokusabela okungaba khona noma ukungcola, okungase kuthinte ikhwalithi yezinto ezicutshunguliwe.Ngakho-ke, izinto ezisetshenziswayo kufanele zihlolwe ukuhambisana nezinsimbi ezithile kanye nama-alloys asetshenziselwa ukuqinisekisa ubuqotho bokuncibilika nokusebenza kokucubungula.Ukwengeza, ukuhlanzwa okufanele nokugcinwa kwezinsimbi phakathi kokusebenza kwensimbi okuhlukile kubalulekile ukugwema ukungcoliswa okuphambene nokuqinisekisa ukusebenza okungaguquki.

Imaphi ama-alloys anephuzu eliphezulu lokuncibilika?

Ama-alloys aphezulu ancibilika afaka:

1. Ingxubevange esekwe ku-Tungsten: I-Tungsten inezindawo ezincibilika eziphakeme kakhulu kuzo zonke izinsimbi, futhi ama-alloys ayo njenge-tungsten-rhenium, i-tungsten-molybdenum, njll. iphinde ibonise amaphuzu aphezulu ancibilikayo.

2. Ama-alloys asekelwe ku-molybdenum: I-Molybdenum nama-alloys ayo, njenge-molybdenum titanium zirconium (TZM) ne-molybdenum lanthanum oxide (ML), anamaphuzu aphezulu okuncibilika futhi asetshenziswa ekufakweni kwezinga lokushisa eliphezulu.

3. Ama-alloys ensimbi aphikisayo: Ama-alloys aqukethe izinsimbi eziphikisayo njenge-niobium, i-tantalum, ne-rhenium aziwa ngamaphoyinti awo aphezulu ancibilika futhi asetshenziswa ezindaweni ezinezinga lokushisa eliphezulu.

Lawa ma-alloys avame ukusetshenziswa ku-aerospace, ukuzivikela kanye nezicelo zezimboni ezisezingeni eliphezulu ezidinga izinto ezinokumelana nokushisa okuhle kakhulu.
