Muaj qhov sib xws ntawm cov hlau ntshiab thiab qee qib lossis cov npe khoom siv hauv Nyij Pooj, txawm hais tias nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov npe thiab cov qauv yuav txawv raws li lub teb chaws thiab cov tuam txhab tsim khoom. Nov yog cov ntsiab lus ntawm yuav ua li cas cov qib hlau ntshiab raug xaiv thiab qee qhov piv txwv uas yuav piv tau:
Purity Standards thiab Qib naming
Ntiaj teb no Standardization:
Cov hlau ntshiab, tsis hais qhov twg nws tau tsim, feem ntau yog tus cwj pwm los ntawm nws cov qib purity siab, nrog cov tsis tshua muaj siab ntawm impurities xws li oxygen, nitrogen, thiab carbon.
Thoob plaws ntiaj teb, tej zaum yuav muaj cov qauv txheej txheem rau kev qhia qhov purity ntawm hlau, feem ntau suav nrog cov lej lej lossis cov npe tshwj xeeb.
Japanese Hom Lub Npe thiab Cov Qauv:
Hauv Nyij Pooj, cov qib steel thiab hlau feem ntau raug xaiv los ntawm kev sib xyaw ntawm cov ntawv thiab cov lej, ua raws li cov qauv kev lag luam Japanese (JIS).
Rau cov hlau ntshiab, cov qib tshwj xeeb yuav raug txheeb xyuas los ntawm lawv cov lej JIS tshwj xeeb lossis cov npe hom.
Qib sib piv
High-Purity Hlau Qib:
Japanese steel mills tuaj yeem tsim cov qib high-purity hlau uas piv rau cov qauv thoob ntiaj teb lees paub.
Piv txwv li, qib zoo li DL4M, tsim los ntawm Kobe Steel hauv Nyij Pooj, paub txog lawv cov kev huv huv thiab tsim nyog rau kev tsim khoom siv hlau nplaum nyuaj.
ARMCO Hlau:
Txawm hais tias muaj keeb kwm los ntawm Tebchaws Meskas (tsim los ntawm ARMCO Steel Company), ARMCO hlau yog cov qib high-purity hlau uas muaj cov khoom zoo sib nqus thiab corrosion kuj.
Nws cov qauv purity thiab daim ntawv thov ua rau nws piv rau qee cov qib high-end ntshiab hlau ua nyob rau hauv Nyiv.
Generic Pure Iron Qib:
Hauv kev nkag siab dav dua, qib zoo li F-1, uas yog cov yam ntxwv los ntawm lawv cov qib impurity tsawg thiab kev ua haujlwm zoo, sib nqus, thiab hluav taws xob, tej zaum yuav muaj cov khoom sib xws hauv Nyij Pooj uas ua tau raws li qhov zoo sib xws thiab kev ua haujlwm zoo.
Xaus
Txawm hais tias tej zaum yuav tsis muaj kev sib txuas lus ncaj qha ntawm cov qib hlau ntshiab uas tsim nyob rau hauv ntau lub teb chaws, cov ntsiab lus tseem ceeb ntawm purity thiab kev ua tau zoo nyob ib puag ncig thoob ntiaj teb. Japanese steel mills, zoo li cov nyob rau hauv lwm lub teb chaws, siv zog los tsim high-purity hlau qib uas ua tau raws li qhov xav tau ntawm ntau yam kev siv hauv kev lag luam. Yog li ntawd, nws muaj peev xwm nrhiav tau Japanese ntshiab hlau qib uas piv rau cov uas tsim nyob rau lwm qhov ntawm purity, kev ua tau zoo, thiab haum rau kev siv tshwj xeeb.
