Fluxing Additives
Materials containing SiO2, Al2O3, CaO, MgO, and other components forming the most stable chemical bonds with oxides (the reduction reaction products). These materials introduced into the charge to lower (raise) the slag melting temperature, reduce slag viscosity, and diminish the impurities concentration in the ferroalloy. That in turn results in more complete base element extraction and ferroalloy quality improvement.
