Ferro Silicon 75 United Elsitives

Ferrosilicon, ib qho tseem ceeb muaj cov tshuaj lom neeg FESI, yog cov khoom siv tseem ceeb hauv kev tsim khoom niaj hnub, tshwj xeeb hauv kev lag luam statmaking, thiab kev lag luam siv tshuaj lom neeg. Tsim los ntawm cov hlau thiab silicon, nrog silicon cov ntsiab lus xws li ntawm 15% mus rau 90%, nws cov khoom ua rau nws tsis tseem ceeb rau cov ntawv thov ntau me me. Feem ntau cov kev coj ua lag luam suav nrog FESI75 (75% silicon), fesi65 (65% silicon qib nyiam FESI45, txhua qhov kev txiav tawm rau cov kev lag luam muaj.

Kev tsim cov ferrosilicon pib nrog cov khoom siv raw high-silica (sitiofe) nyob rau hauv daim ntawv ntawm quartz lossis xuab zeb, cov khoom siv roj av zoo li cov hlau scrap lossis hlau ore. Cov khoom xyaw no tau them rau hauv submerged arc rurnaces kev ua haujlwm ntawm qhov kub tshaj 1,800 degree. Cov txheej txheem smelting cuam tshuam nrog cov tshuaj tiv thaiv carbothermic nyob qhov twg cov pa roj carlica rau cov roj cua silica rau cov hlau los ua cov alloy. Kev tswj nruj ntawm cov khoom siv raw piv thiab ua kom sov cov ntsiab lus uas xav tau cov ntsiab lus silicon zoo li txhuas, calcium, leej faj, thiab phosphorus.

Kev tswj kom zoo yog qhov tseem ceeb hauv cov khoom siv ferrosilicon. Cov kws tsim khoom lag luam ua lag luam kev lag luam nce qib siab xws li X-Tshav Fluorescence (XRF) thiab kev sib txuas ntawm daim phiaj ntshav (ICP) los xyuas cov tshuaj lom neeg. Lub zog lub cev zoo li kev faib tawm qhov loj me (xws li los ntawm Lumps kom muaj hmoov) kuj tau ua kom tau raws li cov neeg siv khoom rau cov ntawv thov sib txawv. Raws li qhov tshwm sim, ferrosilicon muaj cov kev ua tau zoo ib yam hauv deoxidation, kev ua kom zoo, thiab cov txheej txheem inocidic kev ntseeg tau rau cov neeg lag luam thoob ntiaj teb.
