Deoxidizer suroviny ferrosilicon

Produkce Ferrosiliconu je intenzivní proces multi -kroku a energie, který vyžaduje pečlivou kontrolu různých parametrů . Suroviny zahrnují hlavně oxid křemičitý (obvykle ve formě křemene nebo písku), koks jako redukční činidlo a zdroj železa, jako je šrot nebo mlýn {.

Počáteční krok zahrnuje nabíjení těchto surovin do pece . pro Ferrosilicon s nižším obsahem křemíku (až přibližně 15%), vysoká pec lemovaná cihelmi s kyselým ohněm je používána . v této peci, typicky kolem 1500 - 1800 {4} {4}1500 - 18001500 - 18001500 - 18001500 - 1800 Coke reacts with the oxygen in silica, reducing it to silicon. The iron source then combines with the newly formed silicon to create ferrosilicon. When it comes to producing ferrosilicon with higher silicon content, an electric arc furnace is used. The intense heat generated by the electric arcs provides the energy necessary for the reduction reactions. During the production process, it is crucial to control the ratio of raw materials accurately. An overabundance of silica is maintained to avoid the formation of silicon carbide, which can affect the quality of the final product. Additionally, the process also yields microsilica as a valuable by - product, which has applications in areas like the construction industry for Zlepšení síly a trvanlivosti betonu .
