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.
Abstract
Overview
ISO 4695:2021 - "Iron ores for blast furnace feedstocks - Determination of the reducibility by the rate of reduction index" defines a laboratory test method to provide a for iron ores used as blast furnace feedstocks. The method simulates conditions in the blast furnace reduction zone and is applicable to . The fifth edition (2021) is a minor revision of the previous edition.
