Development of technology for the smelting of new complex aluminum-chromium-silicon alloy (AChS)(Zh. Abishev ChMI)

The proposed flow diagram is simple and allows considered poor chrome ore not only as an integrated metallurgical raw materials, but also use as a reducer of the high-in-ash low-phosphorus coals.
