Yuav ua li cas xam cov Coke Ntxiv hauv Smelting Ferrosilicon

Cov teeb meem hauv qab no yuav tsum tau qhia meej ua ntej kev suav:

Cov qib sib txawv ntawm ferrosilicon muaj cov ntsiab lus sib txawv, yog li qhov kev rov qab los ntawm cov pa roj carbon ntau thiab silicon kuj sib txawv hauv kev suav. Lub smelting kub ntawm ferrosilicon yog tsawg, thiab smelting kub ntawm carbon thiab silicon yog siab, yog li qhov poob ntawm carbon thiab silicon yog loj, yog li cov pa roj carbon ntau yog xam raws li 10%, thiab txo tus nqi ntawm silicon yog xam li 92%. .

2. Kev suav ntawm Atomic thiab Molecular Nyhav

Raws li lub sij hawm lub sij hawm ntawm cov tshuaj, lub atomic hnyav ntawm Si yog 28, lub atomic luj ntawm C yog 12, thiab lub atomic hnyav (O) ntawm oxygen yog 16. Yog li ntawd, lub molecular hnyav ntawm SiO2 yog 28+16 × 2=60.

3.

(1) Xam cov coke ntxiv rau smelt 75 ferrosilicon

Rau qhov yooj yim ntawm kev xam, tus nqi ntawm coke ntxiv yog xam raws li 100 kg ntawm silica.

SiO2 cov ntsiab lus ntawm 100 kg ntawm silica yog: 100 × 98% =98 kg

Silicon ferroalloy cov tshuaj tiv thaiv mis: SiO2+2C=Si+2CO

Molecular Luj ntawm SiO2 thiab 2C: 28+2 × 16=60 2 × 12=24

Cov ntsiab lus ntshiab carbon ntawm 90 kg ntawm SiO2 yog: 24/60 × 98=39.2 kg

Peb siv coke uas muaj 84% carbon. Yog tias peb hloov 39.2 kg ntawm ntshiab carbon rau hauv coke, nws yuav yog: 100/84 × 39.2=46.6 kg.

Thaum smelting 75% ntawm ferrosilicon, qhov poob ntawm coke yog li 10%, yog li tus nqi ntawm coke noj yog:

46.6 × 100 / 90=51.7 kg≡52 kg.

Kev paub qhia tau hais tias rau txhua 1% nce hauv cov ntsiab lus coke, 0.6 kg ntawm coke yuav tsum tau ntxiv. Yog tias cov ntsiab lus coke raug suav ua 5%, ces qhov tseeb ntawm coke ntxiv yuav yog: 52+52 × 5% × 0.6≈54 kg.

Yog tias peb ua kom yooj yim cov qauv kev suav saum toj no, ces thaum smelting 75 ferrosilicon, tus nqi ntawm coke ntxiv rau 100 kg ntawm pob zeb yuav yog:

100 × SiO2 × 24/60 × C% × 0.90=coke (kg).

Hauv cov qauv, SiO2 yog cov ntsiab lus carbon dioxide hauv silicon% C

% yog cov ntsiab lus ntawm cov pa roj carbon monoxide hauv coke%0 9-carbon

kev siv yam khoom (vim cov pa roj carbon burnup los ntawm 10%);

24 thiab 60 molecular luj ntawm 2 carbon thiab silica, feem.

Tus nqi ntawm coke ntxiv xam raws li cov qauv yooj yim tsis yog qhov tsim nyog, tab sis yuav tsum tau nce ntxiv raws li cov ntsiab lus coke.

. (2) Xam cov coke ntxiv rau smelt 45 ferrosilicon.

Qhov kev suav no tsis txawv ntau los ntawm kev suav cov nyiaj coke ntxiv rau smelt 75 ferrosilicon. Qhov sib txawv tsuas yog qhov kub ntawm lub cub tawg yog qhov qis thiab qhov poob ntawm coke tsawg dua, yog li nws raug xam raws li 7%. Siv cov qauv yooj yim uas tau muab los saum toj no, kev suav ntawm cov nyiaj ntxiv ntawm coke yog raws li hauv qab no:

Tus nqi ntawm cov coke ntxiv {{0}} × SiO2% × 24/60 × C% × 0.93

Qhov twg 0.93 yog tus nqi siv coke (vim qhov poob hauv casting 45 ferrosilicon coke yog 7%), hloov cov khoom siv raw hauv koj cov

tus nqi ntxiv ntawm coke {{{0}}} × 0.98 × 24/60 × 0.84 × 0.93=50 kg.

Piv txwv li: cov dej ntsiab lus ntawm coke yog xam raws li 5%, qhov tseeb tus nqi ntawm cov coke ntxiv yog:

{{0}} × 5% × 0.6=52 kg.
