High Purity Chromium Hlau yog ua tiav los ntawm electrolytic refining thiab siab - nqus degassing kom ua tiav qhov purity yam tsawg kawg nkaus ntawm 99.9%. Engineered rau siab -kub superalloys, advanced stainless steels, thiab functional txheej deposition, nws muab nruj tswj nyob rau hauv cov kab lus interstitial ntsiab kom tshem tawm cov inclusion defects nyob rau hauv lub nqus tsev vacuum- melting furnaces.
Ntsiab nta
Tswj Interstitials
Txo cov pa oxygen, nitrogen, thiab cov pa roj carbon tsawg los tiv thaiv embrittlement thiab gas porosity hauv nickel{0}} thiab cobalt-raws li superalloys.
Batch Traceability
Txhua qhov ntau lawm yog taug qab los ntawm cov khoom siv raw khoom los ntawm kev sib tsoo zaum kawg, nrog rau kev ua tiav spectrographic pov thawj.
Optimized Morphology
Muaj nyob rau hauv cov flakes tsis tu ncua, lub tshuab nqus tsev -cov khoom melted, los yog kev cai- tshuaj ntsuam granules los tswj kev sib cais kinetics thiab txo cov yaj poob.

FAQ
Q: Koj puas tuaj yeem kho qhov loj me me rau qhov tshwj xeeb nqus induction melting (VIM)?
A: Yog. Crushed flakes tuaj yeem ua tau mechanically sieved rau cov kev cai feem ntau (piv txwv li, 10 - 30 hli los yog nplua granules) kom optimize lub cub tawg them ceev.
Q: Yuav ua li cas yog interstitial gas ntsiab lus (O, N, H) txo thaum lub sij hawm tsim khoom?
A: Cov qib roj tau txo qis siv siab - qhov kub ntawm lub tshuab nqus tsev degassing qhov cub ua haujlwm qis dua 10^-3 Pa, ua raws li kev ntim tshuaj hermetic nyob rau hauv ib qho chaw inert argon.
Q: Koj puas ua raws li thib peb - tog ua ntej - kev tshuaj xyuas khoom xa tuaj?
A: Yog. Kev tshuaj xyuas los ntawm cov koom haum ywj pheej xws li SGS lossis Bureau Veritas tuaj yeem sib koom ua ntej xa tawm raws li daim ntawv cog lus tshwj xeeb.
