1. Tshawb xyuas qhov zoo ntawmferrosiliconlos ntawm cov khoom siv raw;
Silica yog cov khoom siv tseem ceeb tshaj plaws rau kev tsim cov ferrosilicon, yog li qhov zoo ntawm silica kuj txiav txim siab qhov zoo ntawm ferrosilicon. Cov ntsiab lus ntawm silicon hauv silica yuav tsum muaj ntau dua 97%, thiab silica feem ntau tsim cov khoom ntawm txhuas oxide thaum smelting. Cov khoom no tsis tsuas yog cuam tshuam cov teeb meem slag tawm thaum lub sij hawm steelmaking, tab sis kuj ua rau cov khoom txhuas hauv ferrosilicon. Zoo heev cuam tshuam qhov zoo ntawm ferrosilicon.
Tsawg carbon ferrosilicon
2. Cov ntsiab lus ntawm calcium oxide thiab magnesium oxide cuam tshuam qhov zoo ntawm ferrosilicon
Feem ntau cov ntsiab lus ntawm calcium oxide thiab magnesium oxide hauv ferrosilicon yuav tsum tsawg dua 1%. Yog tias nws ntau dua li qhov no, tus nqi ntawm smelting slag yuav nce thaum lub sij hawm steelmaking thiab yaig ntawm lub taphole yuav cuam tshuam rau qhov zoo ntawm ferrosilicon.
ultra-low carbon ferrosilicon
3. Qhov luaj li cas ntawm silica kuj yog ib qho tseem ceeb uas cuam tshuam rau qhov zoo ntawm ferrosilicon.
