Minerais de fer pour charges de hauts fourneaux — Détermination de la réductibilité à partir de la vitesse de réduction

This edition has been replaced by ISO 4695:2021.

Abstract / scope

ISO 4695:2015 specifies a method to provide a relative measure for evaluating the extent to and ease with which oxygen can be removed from iron ores, when reduced under conditions resembling those prevailing in the reduction zone of a blast furnace.

ISO 4695:2015 is applicable to lump ores, sinters and hot-bonded pellets.
