Iron ores for blast furnace feedstocks — Determination of the reducibility by the rate of reduction index

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

Abstract / scope

This document 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.

This document is applicable to lump ores, sinters and hot-bonded pellets.
