ferro silicon phaj

Ferrosiliconyog tsim los ntawm kev txo silica los yog xuab zeb nrog coke nyob rau hauv muaj hlau. Tej qhov chaw ntawm hlau yog seem hlau los yog nplai. ferrosilicon pob, uas muaj txog li 15% silicon, yog tsim nyob rau hauv blast furnaces lined nrog acid refractory cib.

Ferrosilicon, uas muaj cov ntsiab lus ntau dua silicon, yog tsim nyob rau hauv hluav taws xob arc rauv. Feem ntau cov qauv ntawm kev ua lag luam yog ferrosilicon nrog silicon cov ntsiab lus ntawm 15%, 45%, 75% thiab 90%. Cov seem yog hlau, thiab kwv yees li 2% yog ua los ntawm lwm cov khoom xws li txhuas thiab calcium. Siv cov silica ntau dhau los tiv thaiv kev tsim silicon carbide. Microsilica yog ib qho khoom siv tau zoo.

Pearlite zoo ib yam li ferrosilicon thiab nws muaj pes tsawg leeg yog Fe5Si2. Ferrosilicon yuav maj mam tsim cov roj hydrogen thaum sib cuag nrog dej. Cov tshuaj tiv thaiv no tau nrawm dua nyob rau hauv lub xub ntiag ntawm lub hauv paus thiab yog siv los tsim cov roj hydrogen. Lub melting point thiab ntom ntawm ferrosilicon nyob ntawm seb nws cov ntsiab lus silicon, nrog rau ob thaj tsam ze-eutectic, ib qho ze rau Fe2Si thiab qhov thib ob hla FeSi 2-FeSi3 muaj pes tsawg leeg.

Cov khoom siv raw rau kev tsim cov atomized ferrosilicon

Cov khoom siv raw siv los tsim ferrosilicon granule feem ntau yog hlau ore, coke thiab silica. Hlau ore yog qhov tseem ceeb ntawm cov hlau thiab feem ntau yog mined los ntawm qhib qhov av los yog hauv av mines. Tom qab ntawd cov hlau ore yog ua tiav kom tshem tawm impurities thiab crushed rau hauv me me pieces. Coke muab rho tawm los ntawm thee yog siv los ua cov pa roj carbon monoxide hauv ferrosilicon ntau lawm. Silica, feem ntau nyob rau hauv daim ntawv ntawm quartz lossis quartzite, muab cov ntsiab lus silicon tsim nyog.

milled ferrosilicon ntau lawm txheej txheem

Cov txheej txheem ferrosilicon alloys ntau lawm pib nrog kev npaj cov khoom siv raw. Ua tib zoo ntsuas cov hlau ore, coke thiab silica thiab sib tov rau hauv qhov xav tau proportions. Tom qab ntawd cov sib tov yog rhuab nyob rau hauv ib lub qhov cub rau 1,200 mus rau 1,500 degrees Celsius. Qhov kub siab ua rau cov coke ua rau cov pa oxygen hauv cov hlau ore tsim carbon monoxide thiab carbon dioxide. Cov tshuaj tiv thaiv exothermic no muab cov cua sov xav tau rau kev txo cov hlau thiab silicon.
