Low-carbon ferrochrome (generally referring to C ≤ 0.10%, micro-carbon grade C ≤ 0.06%, ultra-micro-carbon grade C ≤ 0.03%) is mainly produced by the two-step refining process via electro-silicothermic method. The complete plant is a closed continuous/semi-continuous refining system, consisting of raw material pretreatment, silicon-chromium smelting, thermal mixing refining, flue gas treatment, automatic control and other systems.
As the core upstream equipment for refining, it is used to produce high-silicon silicon-chromium alloy to provide reducing agent for subsequent decarburization.
Mainly tilting refining furnace, divided into fixed type and rotary type, which is the key equipment determining the final carbon content.
Working Principle
Under alkaline slag environment, Si in silicon-chromium alloy is used to reduce Cr₂O₃, and realize deep decarburization, dephosphorization and desulfurization, finally obtaining micro-carbon ferrochrome with C ≤ 0.03%~0.06%.
