1. Txheej txheem cej luam
Niobium rodyog ib tug high-purity hlau pas nrig nrog zoo heev zog xws li zoo hluav taws xob conductivity, ductility thiab corrosion kuj. Yog li ntawd, nws yog dav siv nyob rau hauv aviation, aerospace, nuclear kev lag luam thiab lwm yam kev lag luam.
2. Raw khoom xaiv
Cov khoom siv raw rau kev tsim cov niobium rods feem ntau yog niobium hmoov thiab qee qhov me me ntawm lwm cov hlau, xws li cobalt thiab hlau. Niobium hmoov yog tsim nrog lub siab tshaj plaws purity, thiaj li hais tias qhov zoo ntawm cov niobium rods txiav yuav zoo dua. Tsis tas li ntawd, cov ntsiab lus ntawm cov hlau doping tseem yuav cuam tshuam qhov zoo ntawm niobium rods. Yog li ntawd, nyob rau hauv cov txheej txheem xaiv raw khoom yuav tsum tau them tshwj xeeb mloog mus rau lub formulation ntawm nruj qauv thiab zoo tswj kom paub tseeb tias qhov zoo ntawm cov khoom tiav.
3. Ua kua
Niobium hmoov yog yaj nyob rau hauv cov cua kub tshwj xeeb thiab hloov mus ua kua niobium. Cov txheej txheem no yuav tsum tau siv cov roj inert feem ntau ua ib qho chaw tiv thaiv kom tsis txhob oxidation thiab purity txo. Qee lwm cov ntaub ntawv hlau tseem yuav raug ntxiv thaum lub sij hawm melting txheej txheem los tsim cov ntsiab lus predetermined. Thaum lub sij hawm tag nrho cov txheej txheem melting, cov neeg ua haujlwm tshwj xeeb kuj yuav tsum tau ua kom ntseeg tau tias kev ua tiav ntawm cov txheej txheem ntau lawm.
4. Cua txias
Tom qab ib lub sij hawm cua sov, cov kua niobium yuav txias thiab solidify ntawm qhov sib thooj kub. Muab cov niobium ingot txias thiab solidified rau hauv lub qhov cub thiab ua kom sov dua kom txog thaum cov kua niobium melts dua. Rov ua qhov haujlwm no ntau zaus los txhim kho qhov purity ntawm niobium pas nrig thiab ua tiav cov khoom ntawm cov khoom siv.
5. Kev txiav
Tom qab txias, niobium ingot yuav hloov mus rau hauv cov khoom loj, thiab tom qab ntawd txiav mus rau hauv cov ntaub ntawv zoo li tus pas nrig ntawm qhov tsim nyog ntev los ntawm cov pliers.
6. Txiav
Tom qab shearing, tus pas nrig niobium tej zaum yuav muaj qee qhov tsis xws luag, xws li nto khawb, npuas, thiab lwm yam, uas yuav cuam tshuam rau qhov zoo ntawm niobium pas nrig. Yog li ntawd, trimming yuav tsum tau tshem tawm cov tsis xws luag, ua rau saum npoo ntawm niobium pas nrig du thiab du, thiab optimize nws cov kev ua tau zoo.
