Yuav ua li cas cov haujlwm nqa tawm thaum lub sijhawm melting ntawm Niobium - Hafnium Alloy thiab kev ua tau zoo ntawm cov alloy?

Niobium hafniumAlloy tej zaum yuav ntsib Impurity Element, Nitrogen, cov pa hluav taws xob, raws li cov tshuab impurities yog qhov kev lag luam smrelting yog qhov kev lag luam kom tswj tau los tswj cov neeg impurity?
1.} tswj hwm cov kev coj dawb huv thiab pretreatment ntawm cov khoom raw
Xaiv Cov Khoom Noj Ntau Tshaj Plaws-Purity Niobium (NB) thiab HF) Cov Khoom Uas Tsis Txaus Ntseeg, xws li cov pa hluav taws xob, thiab cov pa hluav taws xob, thiab cov qauv hlau) yog hauv qab cov txheej txheem kev cai {}}
2.} smelting ib puag ncig tswj
Smelting nyob rau hauv ib puag ncig lub nqus tsev, siv nqus plua plav arc melting (var) los tiv thaiv oxygen nyob rau hauv cov huab cua thiab paug, thiab zam kom tsis txhob muaj oxygen nyob rau hauv cov huab cua thiab tsis huv} Siv all }oy}} oxidation .
3. Xaiv cov khoom tsim nyog melting tsim nyog
Kev siv cov khoom siv nqus tsev siab me me melting xws li lub tshuab nqus tsev nyob hauv lub tshuab hluav taws xob (EBM), lossis ntshav hluav taws xob ua kom zoo nkauj (EBM) ua kom muaj kev cuam tshuam rau cov khoom siv hluav taws xob sab nraud sab nraud.
4. tswj lub suab kub yaj thiab sijhawm
Tsim nyog tswj lub suab kub yaj kom tsis txhob muaj cov khoom tawg thiab tshem tawm cov khoom tawg los yog tshem tawm impurities .
5.} smelting txheej txheem optimization
Thaum lub sij hawm yaj melting, ua kom cov neeg tsis huv (xws li chlorassing tshuab yog siv los txhawb kev siv tshuaj tsis huv (thiab cov neeg loj hauv cov neeg loj hlob los txhim kho cov tshuaj lom neeg los txhim kho cov Alloy .
6. tswj qhov chaw smelting
Xyuas kom muaj kev huv huv ntawm sab hauv phab ntsa ntawm lub cub tawg, thiab ntxuav cov khoom siv tsis tu ncua, thiab tiv thaiv kev ua kom tsis huv thiab tus kheej .
{{07. Txos Igrity Nrhiav thiab Kev Saib Xyuas
Siv GDMS (GLW Kev Tso Tawm Ntau Yam Khoom Siv Hluav Taws Xob txheej txheem .
{{08. Recing Melting Kho thiab Purification
Kub Isostatic Pressing kev kho yog thov kom txo qis hauv cov kab mob uas tsis muaj kev sib tw ntawm cov qauv tshuaj lom neeg thiab cov tshuaj ntsuam xyuas ntawm kev ntsuas tshuaj lom neeg thiab ntsuas lub cev.
