Ferro Silicon Rau Kev Ua Hlau Ntawm Ntau Qhov Loj

Nyob rau hauv luv luv, lubferro silicontxheej txheem yuav piav raws li nram no: Hlau ore (Fe₂O₃), quartz (SiO₂) thiab carbon (C), nyob rau hauv daim ntawv ntawm cov thee, coke thiab biocarbon, yog ntxiv rau saum lub cub tawg. Peb electrodes nyob rau hauv lub cub tawg yog cua sov cov khoom. Thaum kwv yees li 2000˚C cov pa roj carbon reacts nrog cov pa oxygen hauv quartz thiab peb tshuav nrog kua silicon. Cov hlau oxide nyob rau hauv cov hlau ore pellets reacts nrog cov pa roj carbon monoxide los ntawm cov tshuaj tiv thaiv zoo sib xws thiab tsim cov hlau ntshiab. Melted hlau thiab silicon mix thiab ces tapped nyob rau hauv ladles. Covferro siliconhlau yog txias thiab crushed rau hauv daim ntawm qhov sib txawv me me, kom tau raws li cov neeg siv khoom xav tau.

Ferrosilicon yog ib qho alloy ntawm hlau thiab silicon, feem ntau muaj 15% mus rau 90% silicon los ntawm qhov hnyav. Nws yog lub npe hu rau nws lub zog siab, tsis tshua muaj ntom, thiab tsis kam mus corrosion. Cov ntsiab lus ntawm silicon hauv ferrosilicon cuam tshuam nws cov ntsiab lus melting, uas nyob nruab nrab ntawm 1200 degree thiab 1360 degree. Ferrosilicon kuj tsis yog-sib nqus thiab muaj cov thermal conductivity zoo heev, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem ntau lawm. Nws qhov ceev yog li ntawm 2.4 txog 2.8 g / cm³, nyob ntawm seb cov ntsiab lus ntawm silicon, uas tseem cuam tshuam rau nws cov brittleness.
