As the energy consumption problem of an electric arc furnace (EAF) is becoming more and prominent, improving charge resistivity becomes key to reducing metallurgical-grade silicon smelting. This study systematically examines impact mechanism particle size raw materials on electrical burden. The results show that in range 700–1300 °C, consisting coal silica ore decreases from 6–9 mm 0.25–0.3 mm, increases 0.9–1366.7 Ω·m 2.5–2060.5 Ω·m. effects are clarified by investigating how influences ore, along with analysis performed within context modeling. Research shows plays a crucial role affecting charge. largely due alterations graphitization-like degree changes contact resistance between particles. Together, these factors significantly influence overall During this process, increased dramatically mm.
