Xov xwm - Tus nqi ntawm cov hlau txiav txim siab li cas?

Tus nqi ntawm cov hlau yog txiav txim siab los ntawm kev sib xyaw ua ke, feem ntau suav nrog cov hauv qab no:

### Tus Nqi Qis

- ** Tus nqi raw khoom **: Hlau ore, thee, seem hlau, thiab lwm yam yog cov khoom siv tseem ceeb rau kev tsim steel. Kev hloov pauv ntawm cov nqi hlau ore muaj qhov cuam tshuam loj rau cov nqi hlau. Thaum lub ntiaj teb hlau ore mov yog nruj los yog xav tau nce, nws tus nqi nce yuav ua rau cov nqi hlau nce. Raws li lub zog ntawm cov txheej txheem steelmaking, thee hloov pauv tus nqi kuj tseem cuam tshuam rau tus nqi ntawm cov hlau ntau lawm. Cov nqi hlau khib nyiab kuj tseem yuav cuam tshuam rau tus nqi steel. Hauv cov txheej txheem luv luv steelmaking, cov khoom seem hlau yog cov khoom siv tseem ceeb, thiab qhov hloov pauv ntawm cov nqi hlau yuav raug xa ncaj qha mus rau cov nqi hlau.

- ** Tus nqi hluav taws xob **: Kev siv hluav taws xob xws li hluav taws xob thiab cov pa roj carbon monoxide hauv cov txheej txheem steel hlau kuj suav rau qee tus nqi. Kev nce hauv cov nqi hluav taws xob yuav ua rau tus nqi ntawm cov hlau ntau lawm, yog li tsav cov nqi steel.
- ** Tus nqi thauj mus los **: Tus nqi tsheb thauj mus los ntawm cov hlau los ntawm qhov chaw tsim khoom mus rau qhov chaw noj kuj yog ib feem ntawm tus nqi. Kev thauj mus los deb, hom kev thauj mus los, thiab cov khoom siv thiab kev xav tau hauv kev lag luam tsheb thauj mus los yuav cuam tshuam cov nqi tsheb thauj mus los, thiab yog li cuam tshuam rau cov nqi steel.

### Kev Ua Lag Luam thiab Kev Xav Tau

- ** Kev lag luam xav tau **: Kev tsim kho, tshuab tsim, kev lag luam tsheb, khoom siv hauv tsev thiab lwm yam kev lag luam yog cov khoom siv tseem ceeb ntawm cov hlau. Thaum cov kev lag luam no loj hlob sai thiab qhov kev thov rau steel nce, steel nqi yuav nce. Piv txwv li, thaum lub sij hawm booming kev lag luam vaj tse, ib tug loj tus naj npawb ntawm kev tsim kho tej yaam num yuav tsum tau ib tug loj npaum li cas ntawm steel, uas yuav ua rau kom nce steel nqi.
- ** Kev lag luam khoom muag **: Cov yam ntxwv xws li lub peev xwm, cov khoom tsim tawm thiab cov khoom ntim ntawm cov chaw tsim khoom steel txiav txim siab qhov xwm txheej ntawm cov khoom lag luam. Yog tias cov tuam txhab tsim khoom lag luam nthuav dav lawv lub peev xwm, nce cov khoom tsim tawm, lossis cov khoom lag luam ntshuam nce ntxiv, thiab kev lag luam xav tau tsis nce raws li, cov nqi steel yuav poob.

### Macroeconomic Factors

- ** Txoj Cai Kev Lag Luam **: Tsoom fwv txoj cai nyiaj txiag, txoj cai nyiaj txiag thiab kev lag luam txoj cai yuav muaj kev cuam tshuam rau cov nqi hlau. Cov kev cai nyiaj txiag xoob thiab nyiaj txiag yuav txhawb kev loj hlob ntawm kev lag luam, nce kev thov rau steel, thiab yog li tsav cov nqi steel. Qee cov cai tswj kev lag luam uas txwv kev nthuav dav ntawm cov hlau tsim muaj peev xwm thiab ntxiv dag zog rau kev tiv thaiv ib puag ncig yuav cuam tshuam rau cov khoom siv hlau thiab yog li cuam tshuam rau cov nqi.

- **Txoj kev pauv hloov pauv **: Rau cov tuam txhab uas cia siab rau cov khoom siv raw xws li hlau ore lossis cov hlau xa tawm, kev sib pauv hloov pauv yuav cuam tshuam rau lawv cov nqi thiab cov txiaj ntsig. Kev txaus siab ntawm cov txiaj ntsig hauv tebchaws tuaj yeem txo tus nqi ntawm cov khoom siv raw, tab sis yuav ua rau tus nqi ntawm cov hlau xa tawm kuj siab dua hauv kev lag luam thoob ntiaj teb, cuam tshuam rau kev sib tw export; Kev poob qis ntawm cov txiaj ntsig hauv tebchaws yuav nce tus nqi ntshuam, tab sis yuav muaj txiaj ntsig zoo rau kev xa tawm steel.

### Kev Sib Tw Kev Lag Luam

- ** Kev sib tw ua lag luam **: Kev sib tw ntawm cov tuam txhab hauv kev lag luam steel kuj tseem cuam tshuam rau cov nqi steel. Thaum kev sib tw ua lag luam hnyav, cov tuam txhab lag luam tuaj yeem nce lawv cov kev lag luam los ntawm kev txo nqi; thiab thaum kev lag luam concentration siab, cov tuam txhab yuav muaj zog tus nqi zog thiab muaj peev xwm tswj tau tus nqi siab.
- ** Kev sib tw khoom sib txawv **: Qee lub tuam txhab ua tiav cov kev sib tw sib txawv los ntawm kev tsim cov khoom muaj nqis ntxiv, cov khoom siv hlau ua tau zoo, uas yog kim heev. Piv txwv li, cov tuam txhab uas tsim cov hlau tshwj xeeb xws li lub zog siabhlau alloythiabstainless hlautej zaum yuav muaj tus nqi siab dua hauv kev ua lag luam vim muaj cov ntsiab lus siab ntawm lawv cov khoom.
