"FERAL", THE SECONDARY ALUMINIUM FERROALLOY FOR THE DEOXIDIZING AND ALLOYING THE CAST IRON AND STEEL

FERAL, the secondary aluminium ferroalloy for deoxidizing and alloying the steel contains main components - iron and aluminium, and also additive elements and non-ferrous metals. Besides, optimal and stable alloy compositions are found at ratios of the main components : Fe:AL = (8-6):1 for 10-20% AL...

Zusammenfassung:FERAL, the secondary aluminium ferroalloy for deoxidizing and alloying the steel contains main components - iron and aluminium, and also additive elements and non-ferrous metals. Besides, optimal and stable alloy compositions are found at ratios of the main components : Fe:AL = (8-6):1 for 10-20% AL, Fe:AL = (4-2): 1 for 20-50% AL and Fe:AL = 1:(1-3) for AL ?50%, which correspond to the range of homogeneity of stoichiometric intermetallides with the congruent melting point.
