Description
Summary:The paper describes pilot smelting of low-carbon ferrochrome (LCFC) with new type of reductant – multi-component aluminum-silicon-chrome alloy (FASCh). Provisional calculations confirmed by results of pilot smelting show that use of FASCh alloy helps to stabilize LCFC slag and prevent its decomposition. Due to high Al content in FASCh the phase area of slag shifts from dicalcium silicate (larnite- Са<sub>2</sub>SiO<sub>4</sub>) area into the helenite area (2 CaO ∙ Al<sub>2</sub>O<sub>3</sub> ∙ SiO<sub>2</sub>).
