Ferro Zirconium Alloy
Ferro Zirconium Alloy yog tsim los ntawm lub tshuab nqus tsev melting ntawm daim txhuam cev zirconium thiab cov hlau ntshiab raws li cov ntaub ntawv raw. Nws yog tsuas yog siv hauv kev lag luam metallurgical los ua nws lub luag haujlwm muaj zog ntawm deoxidation, tshem tawm nitrogen thiab sulfur tshem tawm.

1. Khoom taw qhia:
Ferro Zirconium Alloy yog tsim los ntawm lub tshuab nqus tsev melting ntawm daim txhuam cev zirconium thiab cov hlau ntshiab raws li cov ntaub ntawv raw. Nws yog tsuas yog siv hauv kev lag luam metallurgical los ua nws lub luag haujlwm muaj zog ntawm deoxidation, tshem tawm nitrogen thiab sulfur tshem tawm. Cov hlau muaj kev tiv thaiv corrosion zoo, cov khoom siv nruab nrab, thiab qis atomic thermal neutron absorption cross section nyob rau hauv qhov kub thiab txias dej thiab chav ntawm 300-400 ° C.
Tsis tas li ntawd, zirconium muaj corrosion kuj zoo heev rau ntau yam acids, bases thiab ntsev, thiab muaj zog affinity rau gases xws li oxygen thiab nitrogen, yog li zirconium alloys kuj siv nyob rau hauv lub tsim ntawm corrosion resistant qhov chaw thiab kws kho tshuab qhov chaw, thiab yog dav siv los ua cov tsis-evaporative degassing cov neeg ua haujlwm hauv lub tshuab nqus tsev hluav taws xob thiab lub teeb teeb kev lag luam.
Ferro Zirconium Alloy nkag tau hydrogen, nitrogen thiab oxygen; zirconium muaj kev sib raug zoo rau cov pa oxygen, thiab cov pa oxygen yaj hauv zirconium ntawm 1000 ° C tuaj yeem ua rau nws qhov ntim ntau ntxiv. Nws nto yooj yim tsim ib txheej ntawm oxide zaj duab xis thiab muaj luster, yog li nws cov tsos zoo ib yam li hlau. Nws kuj yog corrosion resistant, tab sis yog soluble nyob rau hauv hydrofluoric acid thiab aqua regia. Thaum qhov kub thiab txias, nws tuaj yeem hnov mob nrog cov khoom tsis yog xim hlau thiab ntau cov khoom siv hlau los tsim cov kuab tshuaj.
Cov khoom no muaj cov yas zoo thiab tuaj yeem ua tau yooj yim rau hauv daim hlau, xov hlau, thiab lwm yam. Nws tuaj yeem nqus tau ntau cov pa oxygen, hydrogen, nitrogen thiab lwm yam gases thaum rhuab, thiab tuaj yeem siv los ua cov khoom siv hydrogen. Tsis tas li ntawd, nws muaj kev tiv thaiv corrosion zoo dua li titanium thiab ze rau niobium thiab tantalum.
2. Cov ntsiab lus ntawm cov khoom:
Zirconium melting point 1852 ℃. Kub taw tes ntawm 4400 ℃.

4. Khoom siv:
Zirconium ferroalloy feem ntau yog siv hauv steelmaking, NdFeB cov khoom sib nqus hauv qhov sib ntxiv ntawm zirconium, metallurgy casting, vuam kev lag luam. Txo qhov cuam tshuam ntawm oxygen, nitrogen thiab sulfur hauv cov hlau. Nws tuaj yeem txhim kho qhov kub thiab corrosion tsis kam ntawm cov khoom siv hluav taws xob.Zirconium ua zoo li titanium hauv cam khwb cia hlau. Nws tsim zirconium carbide, uas ua ke nrog sulfur los ua sulfides. Accelerates tsim graphite ntawm txias.
