Cov teeb meem hauv qab no yuav tsum tau qhia meej ua ntej xam:
Cov qib sib txawv ntawm ferrosilicon vim qhov sib txawv smelting kub, yog li kev suav ntawm cov pa roj carbon ntau thiab silicon rov qab kuj txawv. Ferrosilicon smelting kub yog qis dua, carbon thiab silicon hauv av ferrosilicon smelting kub yog siab dua, qhov poob ntawm carbon thiab silicon ntau dua, yog li cov pa roj carbon ntau yog xam ntawm 10%, tus nqi rov qab ntawm silicon yog xam ntawm 92%.
2. Atomic hnyav, molecular hnyav xam
Raws li daim ntawv teev cov tshuaj lom neeg tuaj yeem paub tias yog lub cev hnyav ntawm silicon 28, atomic hnyav ntawm carbon yog 12, atomic hnyav ntawm oxygen yog 16, yog li qhov hnyav molecular ntawm SiO2 yog 28 + 16 × {{ 5}} ib.
100 kilograms ntawm silica muaj SiO2: 100 × 98%=98 kilograms.
Ferrosilicon smelting cov tshuaj tiv thaiv mis: SiO2 + 2C=Si + 2CO
SiO2 thiab 2C molecular hnyav: 28 + 2 × 16=60 2 × 12=24
90 kg ntawm SiO2 ntshiab carbon ntau yog: 24/60 × 98=39.2 kilograms
Peb siv coke uas muaj 84% carbon, 39.2 kilograms ntawm ntshiab carbon hloov mus rau coke, nws yog: 100 / 84 × 39.2=46.6 kilograms
Smelting 75 ferrosilicon, lub coke burnout yog li 10%, yog li cov coke kom tsawg yog:
46.6 × 100 / 90=51.7 kg ≡ 52 kg
Cov ntsiab lus dej hauv coke yog li 5% mus rau 15%. Kev paub ua pov thawj tias txhua 1% nce hauv cov ntsiab lus coke, 0.6 kg ntawm coke yuav tsum tau ntxiv raws li. Yog tias cov ntsiab lus coke raug suav ua 5%, qhov tseeb ntawm coke ntxiv yuav yog: 52+52 × 5% × 0.6≈54kg
Simplifying cov saum toj no thiab cov mis laij lej, tus nqi ntawm coke ntxiv rau smelting 75 ferrosilicon rau 100 kilograms ntawm pob zeb yuav:
100 × SiO2 × 24/60 × C% × 0.90=Coke ntxiv (kg)
Qhov twg SiO2- carbon dioxide cov ntsiab lus ntawm silicon hauv %
C% -% taag carbon cov ntsiab lus hauv coke
0.9-Kev siv cov pa roj carbon (10% vim yog carbon burnout).
24 thiab 60- molecular luj ntawm 2 carbon thiab carbon dioxide silicon, feem.
Tus nqi ntawm coke ntxiv, suav nrog cov qauv yooj yim, tsis yog qhov xav tau tiag tiag, tab sis yog nce raws li cov ntsiab lus coke.
(2) Kev suav ntawm cov coke ntxiv rau coke rau smelting 45 ferrosilicon
Qhov no yog tib yam li smelting ntawm 75 ferrosilicon coke ntxiv suav, tsis muaj qhov sib txawv loj, tsuas yog vim qhov kub ntawm qhov cub, coke hlawv poob tsawg dua, raws li kev suav ntawm 7%. Siv cov qauv yooj yim saum toj no, coke ntxiv yog xam raws li:
Coke ntxiv {{0}} × SiO2% × 24/60 × C% × 0.93
Qhov twg 0.93 yog qhov kev siv ntawm coke (vim 45 ferrosilicon coke casting poob ntawm 7%) Hloov cov khoom siv raw rau hauv cov qauv saum toj no.
Coke ntxiv {{0}} x 0.98 x 24/60 x 0.84 x 0.93=50 kg
Piv txwv li: cov dej ntsiab lus hauv coke yog xam ntawm 5%, qhov tseeb ntawm coke ntxiv yog.
{{0}} × 5% × 0.6=52 kg
