Cov txheej txheem tshiab ntawm high-purity ferrosilicon overcomes cov shortcomings ntawm cov tsoos txoj kev, xaiv raw cov ntaub ntawv tsim nyog thiab txheej txheem txheej txheem, thiab tsim high-purity ferrosilicon rau smelting high-qib silicon steel thiab lwm yam kev siv. High-purity ferrosilicon ntau lawm siv xaiv quartzite + roj av coke (los yog roj av coke ntxiv rau ib qho me me ntawm lwm cov pa roj carbon) + silicon steel chips, nyob rau hauv cov ntxhia tshav kub rauv txo, roj av coke particle loj ntawm 0-10 hli, qhov loj tshaj plaws ntawm 0-5mm. rauv tus nqi piv ntawm quartzite: roj av coke: silicon steel chips=100:40-55:5-55, qhov piv ntawm qhov piv no rau cov ntsiab lus ntawm cov pa roj carbon monoxide raws li tus nqi hauv paus.

Quartzite chemical composition (weight) requirements for SiO2>98.0%, Al2O3<0.03%, CaO <0.01%, and other impurities in addition to iron oxide less than 0.02% of the total. The impurity content of the resulting high-purity ferrosilicon products can be controlled in the following ranges; Si and Fe elements for the effective elements, according to the requirements of the use of the adjusted ratio. If necessary, according to the changes in the number of requirements for individual elements, can be in the liquid products out of the furnace into the chlorine gas for 20-40 minutes, 20 kg, or oxygen for 30-40 minutes, 5 kg, or water gas (H2 + H2O) 20-40 minutes, 5 kg, respectively.
