ISO 7215:2015 specifies a method to provide a relative measure for evaluating the extent to which oxygen can be removed from iron ores when reduced under conditions resembling those prevailing in the reduction zone of a blast furnace. ISO 7215:2015 is applicable to lump ore, sinters, and hot-bonded pellets.
Abstract
Overview
ISO 7215:2015 - Iron ores for blast furnace feedstocks - Determination of the reducibility by the final degree of reduction index - specifies a laboratory test method to provide a relative measure of how readily oxygen can be removed from iron ores under conditions resembling the reduction zone of a blast furnace. The method yields the after isothermal reduction at and is applicable to . Results are intended for quality control, contract specification and research.
