Yuav ua li cas Hlau: Cov txheej txheem txheej txheem rau kev tsim khoom ntawm ib qho ntawm cov khoom siv ntau yam hauv ntiaj teb

Hlau yog cov khoom siv tseem ceeb hauv peb lub neej niaj hnub, muaj nyob hauv ntau yam khoom thiab cov qauv uas peb siv txhua hnub. Los ntawm cov tsheb uas peb tsav mus rau cov tsev uas peb nyob, hlau yog ib feem tseem ceeb ntawm peb lub neej. Tab sis koj puas tau xav paub tias cov khoom siv ntau yam no tsim tau li cas? Hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem kev ua haujlwm tom qab kev tsim steel, los ntawm cov pob zeb hauv av kom tau txais cov khoom kawg.

Extraction thiab npaj cov khoom siv hwm

Cov txheej txheem tsim steel pib nrog kev rho tawm ntawm cov hlau ore, feem ntau yog hematite thiab magnetite, los ntawm qhib qhov av lossis hauv av mines. Cov zaub mov no tau dhau los ua cov txheej txheem los tshem tawm impurities thiab tau txais hlau ore. zoo tsim nyog rau kev tsim cov hlau. Thaum cov pob zeb no tau txais, nws dhau los ua cov txheej txheem sib tsoo thiab sib tsoo los hloov nws mus rau hauv cov hmoov zoo hu ua "hlau ore concentrate."

Lub Blast Rauv: Qhov Chaw Khawv koob ntawm Hlau Pib

Hauv cov kauj ruam tom ntej ntawm cov txheej txheem, cov hlau ore concentrate yog nkag mus rau hauv lub cub tawg nrog rau coke thiab limestone. Lub tshuab hluav taws xob tawg yog cov qauv loj uas muaj cov tshuaj tiv thaiv tshuaj hu ua txo qis. Thaum lub sij hawm no cov tshuaj tiv thaiv, hlau yog sib cais los ntawm oxygen thiab ib tug kua hu ua "npua hlau" yog tau, uas muaj kwv yees li 4% carbon. Qhov kub hauv qhov cub tawg tuaj yeem tshaj 1500 degrees Celsius, uas tso cai rau cov ore melted thiab kua npua hlau tau.

Pig Refining: Tau Txais Hlau

Thaum cov kua npua hlau tau txais, cov txheej txheem refining yog nqa tawm kom tau txais cov hlau xav tau. Cov npua hlau tau dhau los ua cov txheej txheem oxidation hauv lub converter. Cov txheej txheem no Nws siv cov pa oxygen los tshem tawm ib feem ntawm cov pa roj carbon monoxide thiab lwm yam impurities tam sim no nyob rau hauv npua hlau, ua rau cov hlau ua kua. Cov kua hlau no tau ua kom zoo dua ntxiv los ntawm kev ntxiv cov alloys sib txawv thiab kho nws cov tshuaj muaj pes tsawg leeg kom ua tau raws li cov qauv thiab cov kev xav tau ntawm kev siv hlau sib txawv.

Xaus lus

Nyob rau hauv luv luv, cov txheej txheem kev tsim steel yog complex tab sis fascinating. Los ntawm kev rho tawm thiab npaj cov ntaub ntawv zoo tshaj plaws kom tau txais cov hlau kawg, txhua kauj ruam yog qhov tseem ceeb kom tau txais cov khoom siv ntau yam thiab zoo. Raws li peb txuas ntxiv tshawb nrhiav lub ntiaj teb ntawm cov hlau, peb tuaj yeem txaus siab rau nws qhov cuam tshuam rau peb lub neej thiab yuav ua li cas nws txoj kev tsim khoom yuav tsum muaj kev paub txog kev paub thiab precision.

- Cov yam ntxwv thiab muaj pes tsawg leeg ntawm cov hlau

Hlau yog cov khoom siv dav siv hauv ntau qhov kev lag luam vim nws cov yam ntxwv thiab nws muaj pes tsawg leeg. Kev nkag siab txog kev tsim cov hlau li cas yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig hauv peb lub neej. Hlau yog ib qho alloy ntawm hlau thiab carbon, qhov twg cov ntsiab lus carbon txiav txim nws cov khoom thiab kev siv tshwj xeeb. Txhawm rau tsim cov hlau, yuav tsum muaj ntau cov kauj ruam uas koom nrog ntau txoj hauv kev thiab thev naus laus zis.

Cov txheej txheem tsim steel pib nrog kev tshem tawm cov hlau ore. Cov ntxhia no muaj nyob rau hauv ntau qhov ntau thiab muab rho tawm los ntawm qhov qhib qhib lossis hauv av mining. Thaum cov hlau ore tau muab rho tawm, nws dhau los ua cov txheej txheem crushing thiab sib tsoo kom tau txais qhov loj me me. Sib nqus sib cais yog ces ua kom tshem tawm impurities.

Tom qab sib nqus sib nqus, hlau ore raug txo qis hauv qhov cub tawg. Nyob rau hauv cov txheej txheem no, nws yog tov nrog coke (ib tug roj muab tau los ntawm thee) thiab limestone. Kev sib xyaw ua ke yog rhuab mus rau qhov kub siab nyob rau hauv lub xub ntiag ntawm huab cua kub, ua rau lub melting ntawm cov hlau ore thiab tsim cov kua hlau.
