An iron alloy that contains a sufficient amount of one or more chemical elements as alloying or reducing 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 …
A portion of material separated out based on a specific characteristic: particle or grain size (in screen analysis) and density (in gravity concentration).
A furnace’s lowest part where fuel combustion and liquid metal accumulation take place.
