Ferrosilicon Production

Ferrosilicon yog tsim los ntawm kev txo silica (SiO2) nrog coke los yog thee nyob rau hauv ib tug hluav taws xob arc rauv. Cov txheej txheem suav nrog cov kauj ruam hauv qab no:

Kev npaj cov ntaub ntawv raw: Cov khoom siv raw, suav nrog silica, coke, thiab hlau, raug xaiv thiab ua tiav kom tau raws li cov kev cai tshwj xeeb ntawm qib ferrosilicon.

Lub tshuab hluav taws xob them hluav taws xob: Cov ntaub ntawv npaj tau raug thauj mus rau hauv hluav taws xob arc rauv thiab yaj los ntawm cov cua sov uas tsim los ntawm hluav taws xob arc.

Kev txo qis: Cov pa roj carbon los ntawm coke lossis thee reacts nrog oxygen hauv silica los tsim cov pa roj carbon monoxide thiab carbon dioxide gases. Cov pa roj carbon monoxide tom qab ntawd ua rau cov hlau ua kua hlau thiab cov pa roj carbon dioxide. Cov tshuaj tiv thaiv yog exothermic thiab tsim ib qho tseem ceeb ntawm tshav kub.

Alloying: Cov kua hlau reacts nrog cov silica seem los tsim ferrosilicon. Cov ntsiab lus ntawm silicon ntawm ferrosilicon nyob ntawm seb cov silica ntxiv rau qhov cub.

Tapping: Lub molten ferrosilicon yog tapping los ntawm lub cub tawg thiab cam khwb cia rau hauv pwm los tsim cov khoom blocks los yog crushed rau hauv hmoov.

Tom qab kev kho mob: Lub ferrosilicon txias thiab ua tiav kom tshem tawm cov impurities thiab kho nws cov muaj pes tsawg leeg raws li xav tau.

Qhov zoo thiab cov khoom ntawm ferrosilicon nyob ntawm ntau yam, suav nrog cov khoom siv raw, qhov kub thiab txias ntawm cov txheej txheem txo, thiab tom qab kev kho mob.
