441 Qib Silicon Hlau

Feem ntau ntawm cov silicon recycled yog siv nyob rau hauv zus tau tej cov hlau thiab hlau. Ferrosilicon tuaj yeem muaj cov ntsiab lus silicon li ntawm 15% txog 90%. Los tsim ferrosilicon, hlau thiab silicon yog yaj ua ke. Cov txheej txheem cuam tshuam nrog crushing ore thiab carbon, uas tom qab ntawd muab tso rau hauv lub cub tawg nrog rau seem hlau. Thaum kub tshaj 1900 degree, carbon reacts nrog oxygen nyob rau hauv cov ore, tsim carbon monoxide. Cov hlau thiab silicon sib xyaw ua ke los ua cov kua hu ua ferrosilicon, uas tuaj yeem muab rho tawm los ntawm lub qhov cub hauv qab. Tom qab txias, ferrosilicon npaj txhij rau kev xa khoom thiab tuaj yeem siv rau hauv kev tsim hlau thiab hlau. Cov txheej txheem tib yam no kuj yog ua haujlwm los tsim cov silicon nrog purity ntau dua 99%. Tsis tas li ntawd, silicon yog siv nyob rau hauv steel smelting, aluminium cam khwb cia alloys, thiab silane tshuaj.
