Inkcazelo emfutshane:

Ubushushu obuphezulu be-tungsten alloy furnace crucible sisitya esikhethekileyo esisetyenziselwa ukunyibilika kwaye siqulethe izinto kumaqondo obushushu aphezulu kakhulu. Ii-alloys ze-Tungsten zihlala zikhethwa kwii-crucibles ngenxa yendawo yazo ephezulu yokunyibilika, i-thermal conductivity egqwesileyo kunye nokuchasana nokuhlaselwa kweekhemikhali.

Bubuphi obona bushushu bobushushu be-tungsten crucible?

Ukushisa okuphezulu kwe-tungsten crucible kuxhomekeke kwizinto ezithile ze-tungsten alloy kunye nenkqubo yokuvelisa. Ngokubanzi, ii-tungsten crucibles ziyakwazi ukumelana namaqondo obushushu angaphezu kwe-3000 ° C (5432 ° F), nto leyo ezenza zilungele ukusetyenzwa kwemathiriyeli ezifuna amaqondo obushushu aphezulu kakhulu, njengokunyibilika kunye nokujulwa kwesinyithi, iiseramikhi, kunye nobunye ubushushu obuphezulu. izixhobo. Nangona kunjalo, ukubunjwa kwe-alloy ethile kunye nokusebenzisana okunokwenzeka kunye nezinto ezicutshungulwayo kufuneka ziqwalaselwe ukuqinisekisa ukusebenza kwe-crucible phezu komgangatho wokushisa okulindelekileyo.

Ngaba ungasebenzisa icrucible efanayo kwiintsimbi ezahlukeneyo?

Ewe, i-tungsten crucibles ingasetyenziswa ngeentsimbi ezahlukeneyo, kodwa kubalulekile ukuqwalasela ukuhambelana kwezinto ezixutywayo kunye nentsimbi ethile ecutshungulwayo. I-Tungsten crucibles ivame ukukhethwa ngenxa yokuchasana nokushisa okuphezulu kunye nokubola kweekhemikhali, okwenza ukuba zifaneleke kwiindidi ezahlukeneyo zokunyibilika kwesinyithi kunye nokucubungula izicelo. Nangona kunjalo, iintsimbi ezithile okanye i-alloys zetsimbi zinokuba nokusebenzisana okuthe ngqo kunye ne-crucible material, njengokuphendula okunokwenzeka okanye ukungcola, okunokuchaphazela umgangatho wezinto ezicutshungulwayo. Ngoko ke, izinto ezinqamlekileyo kufuneka zihlolwe ukuhambelana nezinyithi ezithile kunye ne-alloys ezisetyenziselwa ukuqinisekisa ukunyaniseka kwemisebenzi yokunyibilika kunye nokucubungula. Ukongezelela, ukucocwa okufanelekileyo kunye nokugcinwa kwee-crucibles phakathi kwee-metalworking runs ezahlukeneyo kubalulekile ukuphepha ukungcola kunye nokuqinisekisa ukusebenza okuhambelanayo.

Zeziphi iingxubevange ezinendawo ephezulu yokunyibilika?

Iindawo ezinyibilikayo eziphezulu zibandakanya:

1. I-alloy esekelwe kwi-Tungsten: I-Tungsten ineyona ndawo iphakamileyo yokunyibilika phakathi kwazo zonke iintsimbi, kunye ne-alloys zayo ezifana ne-tungsten-rhenium, i-tungsten-molybdenum, njl.

2. I-alloys esekelwe kwi-Molybdenum: I-Molybdenum kunye ne-alloys yayo, njenge-molybdenum titanium zirconium (TZM) kunye ne-molybdenum lanthanum oxide (ML), zineendawo eziphezulu zokunyibilika kwaye zisetyenziselwa ukusetyenziswa kweqondo lokushisa eliphezulu.

3. I-alloys yensimbi ephikisayo: I-alloys equkethe i-metals refractory efana ne-niobium, i-tantalum, kunye ne-rhenium ziyaziwa ngeendawo eziphezulu zokunyibilika kwazo kwaye zisetyenziselwa kwiindawo eziphezulu zokushisa.

Ezi alloys ziqhele ukusetyenziswa kwi-aerospace, ukukhusela kunye nokushisa okuphezulu kwezicelo zemizi-mveliso ezifuna izinto ezinokumelana nokushisa okukhulu.
