Cov hlau ntshiab nrog cov sulfur thiab phosphorus cov ntsiab lus hauv qab no 0.002% yog cov khoom siv purity siab uas muaj cov khoom tshwj xeeb thiab kev siv. Hauv qab no yog cov ncauj lus kom ntxaws txog hom hlau ntshiab no:
Kev sib xyaw thiab cov yam ntxwv
Cov ntsiab lus sulfur: Hauv qab no 0.002%
Cov ntsiab lus phosphorus: Hauv qab no 0.002%
Cov qib impurity qis no ua rau cov hlau ntshiab uas muaj cov khoom siv kho tshuab zoo heev, muaj kev tiv thaiv corrosion siab, thiab kev ua haujlwm ruaj khov. Cov ntsiab lus tsis tshua muaj leej faj thiab phosphorus tseem ua rau nws siv hauv kev lag luam tshwj xeeb thiab kev siv.
Daim ntawv thov
Vim nws cov purity siab thiab ruaj khov, cov hlau ntshiab nrog cov sulfur thiab phosphorus cov ntsiab lus hauv qab no 0.002% yog dav siv nyob rau hauv ntau yam teb:
Kev lag luam hluav taws xob:
Nws yog siv los tsim cov khoom siv hluav taws xob thiab cov khoom siv, xws li transformers, inductors, thiab magnetic cores, vim nws cov khoom siv hluav taws xob zoo thiab sib nqus.
Aerospace Kev Lag Luam:
Nws yog siv nyob rau hauv kev tsim cov aircraft thiab spacecraft Cheebtsam, qhov twg siab zog, lub teeb yuag, thiab corrosion kuj tseem ceeb heev.
Kev lag luam tshuaj:
Nws yog siv rau hauv cov khoom siv thiab cov kav dej uas siv cov tshuaj corrosive, ua tsaug rau nws zoo heev corrosion kuj.
Kev lag luam kho mob:
Nws yog siv rau hauv kev tsim cov khoom siv kho mob thiab cog, qhov twg biocompatibility thiab corrosion kuj yog qhov tseem ceeb.
Precision Machinery:
Nws yog siv nyob rau hauv zus tau tej cov precision machinery thiab cov cuab yeej, qhov twg siab precision thiab ruaj khov kev kawm yuav tsum tau.
Kev tsim khoom thiab kev ua haujlwm
Kev tsim cov hlau ntshiab nrog leej faj thiab phosphorus cov ntsiab lus hauv qab no 0.002% suav nrog ntau cov kauj ruam, suav nrog kev xaiv raw khoom, smelting, refining, thiab shaping. Thaum lub sij hawm tsim cov txheej txheem, kev tswj xyuas nruj nruj yog coj los xyuas kom meej tias cov qib impurity tau khaws cia nyob rau hauv qhov kev teev tseg.
Tsis tas li ntawd, cov txheej txheem tshwj xeeb yuav tsum tau ua kom zoo ntxiv rau cov khoom ntawm cov hlau ntshiab, xws li annealing, quenching, thiab tempering. Cov txheej txheem kev ua haujlwm no tuaj yeem txhim kho cov khoom siv kho tshuab, tiv thaiv corrosion, thiab hnav tsis kam ntawm cov khoom.
