Yuav ua li cas cov txheej txheem hlau?

Cov txheej txheem ntawm cov hlau feem ntau suav nrog kev ua hlau, ua hlau thiab steel dov, uas yog luv luv piav qhia raws li nram no:

1. Kev ua hlau: Nws yog cov txheej txheem ntawm kev txo hlau nyob rau hauv sinter thiab pob zeb. Coke, sinter, thiab cov tawv pob zeb, ua ke nrog me me ntawm limestone, raug xa mus rau lub tshuab ua kom tawg rau kev sib tsoo rau cov kua ua kua hlau (dej hlau), uas yog tom qab ntawd xa mus rau hlau zeb ua cov khoom siv raw rau cov hlau ua hlau.

2. Steelmaking: Nws tshem tawm cov pa roj carbon ntau dhau, sulfur, phosphorus thiab lwm cov impurities los ntawm cov ntaub ntawv nyoos (hlau dej thiab cov hlau seem, thiab lwm yam) thiab ntxiv cov alloy tsim nyog.

3. Cov hlau nruam txuas ntxiv: Cov hlau molten yog txuas ntxiv mus rau hauv cov dej-cov khoom txias los ntawm cov dej nruab nrab, thiab tom qab muab cov khoom sib xyaw ua rau lub plhaub lawm, nws tau rub tawm los ntawm cov khoom siv crystallizer ntawm lub nrawm, thiab tom qab ntawd txias los ntawm dej tsuag. Tom qab txhua qhov ua kom tiav, nws yuav raug txiav mus rau Kev Tsim Qhov ntev ntawm kev nruam casting billet.

4. Dov: Cov ntawv txuas ntxiv nrum steel ingots thiab nruam cov ntawv xa khoom vias yog dov rau hauv ntau hom hlau hauv cov tshuab sib txawv yob los ntawm kev kub dov.

Nws muaj peb txoj kev tseem ceeb ntawm smelting: kev ncaj qha steelmaking, ncaj qha steelmaking, thiab smelting txo.

1. Indirect steelmaking txoj kev. Nws muaj ob kauj ruam: tshuab ua cua sov ua kom sov hlau ua thiab hloov ua hlau. Cov hlau ua hlau yog thawj zaug yaj thiab txo kom npua hlau (muaj cov pa roj carbon ntau heev), thiab tom qab ntawd cov hlau hlau yog them rau lub cub hluav taws xob rau hlau oxidation thiab refining rau hauv hlau, uas yog cov qauv loj rau huab hwm coj ntau lawm niaj hnub steel smelting.

2. Txoj kev siv hlau ncaj qha. Ib txoj kev ntawm smelting steel rau hauv hlau los ntawm ib kauj ruam. Hloov chaw ntawm qhov cub tawg thiab cov coke kim, cov qauv siv hlau ore hauv qhov cub hluav taws xob ncaj qha kom txo cov carbonaceous (<1%), semi-molten="" hemite="" muaj="" impurities="" nrog="" lub="" roj="" lossis="" cov="" khoom="" ua="" kom="" txo="">

3. Melting txo txoj kev. Ib txoj hauv kev uas tsis yog tawg ua kom sov ua kom sib xyaw hlau uas ua kom cov hlau tsis zoo yog txo rau cov hlau hlau los ntawm cov pa roj carbon nyob rau hauv lub xeev molten ntawm qhov kub, thiab tom qab ntawd ua kom zoo dua rau hauv cov hlau los ntawm cov pa hloov ua.
