Cov txheej txheem ntau lawm ntawm rebar tsuas yog muaj 6 tus kauj ruam loj

Cov txheej txheem ntau lawm ntawm rebar tsuas yog muaj 6 tus kauj ruam loj:

1. Hlau Ore Tsuas thiab Kev Ua:
Muaj ob hom hematite thiab magnetite uas tau zoo dua smelting kev ua haujlwm thiab siv tus nqi.

2. Coale tsuas thiab Cuming:

Tam sim no, ntau dua 95% ntawm lub ntiaj teb cov hlau tsim tseem siv cov Coke Iron-ua txoj kev tsim los ntawm British Darby 300 xyoo dhau los. Yog li ntawd, Coke yog xav tau rau kev tsim cov hlau-ua, uas yog siv roj. Nyob rau tib lub sijhawm, Coke tseem yog tus neeg sawv cev txo. Dispplap hlau los ntawm hlau oxide.

Coke tsis yog ib qho ntxhia, tab sis yuav tsum yog "ua kom zoo" los ntawm kev sib xyaw ntawm cov thee. Cov feem dav dav yog 25-30% ntawm cov rog rog thiab 30-35% ntawm coking thee, thiab tom qab ntawd muab tso rau hauv lub cub coke thiab carbonized rau 12-24 teev. , tsim cov tawv tawv thiab ntxig ntxig.

3. Lub tshuab hluav taws xob cua tshuab Ironmaking:

Moj ua hluav taws xob hluav taws xob Ironmaking yog rau yaj hlau ore thiab roj (ib leeg yog cov roj tawg, thiab lwm yam raws li cov tshuaj tiv thaiv kom tsawg ntawm qhov kub thiab yog txo los ntawm cov hlau oxide. Cov zis yog qhov tseeb "npua hlau" mas tsim ntawm cov hlau thiab muaj qee cov pa roj carbon, uas yog, Molten hlau.

4. Ua Hlau Rau Hauv Hlau:

Qhov tseem ceeb ntawm cov khoom ntawm cov hlau thiab hlau yog cov ntsiab lus carbon, thiab cov pa roj carbon ntau dua 2% yog qhov tseeb "hlau". Dab tsi yog ib txwm hu ua "steelmaking" yog tus decarburization ntawm npua hlau thaum lub siab-ntsuas hluav taws xob smelting, tig hlau ua hlau. Cov khoom siv steelmaking feem ntau yog lub converter lossis lub cub hluav taws xob.

5. Muab cov nyiaj hli (Casting Billet:

Tam sim no, ntxiv rau kev tsim cov hlau tshwj xeeb thiab cov hlau loj me me, ib qho me me ntawm cov hlau cam khwb cia kev cuam tshuam yog qhov yuav tsum tau ua. Kev tsim cov hlau loj hauv tsev thiab txawv teb chaws tau tso tseg cov txheej txheem qub ntawm Casting Cov.

If you do not wait for the steel billet to cool down, do not land on the way, and directly send it to the rolling mill, you can make the required steel products “in one fire”. Yog tias lub billet yog txias ib nrab thiab khaws cia rau hauv av, lub billet tuaj yeem dhau los ua cov khoom lag luam muag hauv khw.

6. Billet Rolled rau hauv cov khoom:

Nyob rau hauv lub yob ntawm Rolling zeb, lub billet hloov los ntawm coarse kom zoo, tau txais los ze zog ntawm cov khoom, thiab xa mus rau lub txaj cua txias rau cua txias. Feem ntau ntawm cov tuav tau siv rau kev ua cov txheej txheem tshuab thiab yog li ntawd.

Yog tias cov qauv qaws tau siv rau ntawm lub xeem ntawm cov neeg Rebar, nws yog qhov ua tau los tsim cov rebar, cov khoom siv qauv hu ua "rebar".

Cov lus qhia saum toj no hais txog cov txheej txheem ntau lawm ntawm rebar, Kuv vam tias nws yuav pab tau txhua tus.
