Iron ore reducibility

  • A single furnace for testing to one of the following standards or
  • A furnace which can combine up to three of the following ISO standards ISO 4695:2007 - Iron ore reducibility
ISO 4695:2007 - Iron ore reducibility
  • Reducibility may be defined as a measure of the ease with which oxygen combined with iron can be removed from natural or processed iron ores by a reducing gas, which is expressed as the rate of reduction at an atomic ration O/Fe = 0.9, relative to the iron (III) state.
  • Test consists of isothermal reduction of a test portion at a specified size range in a fixed bed at a temperature of 950ºC using a reducing gas consisting of CO and N2.
ISO 4696-1:1996 Low temperature disintegration test
  • Evaluating the disintegration behaviour of iron ores reduced in a fixed bed under specific conditions relevant to the low temperature zone in the blast furnace for iron making. This method is a measure of the breakdown of blast furnace burden materials under conditions resembling those in upper part of the blast furnace.
ISO 4696-2:2007 - Static low temperature reduction
  • Evaluating the reduction behaviour of iron ores reduced in a fixed bed under specific conditions relevant to the low temperature zone in the blast furnace for iron making.
ISO 4698:2007 - Determination of relative free-swelling index
  • Determination of swelling of fired iron ore pellets of a specified size range under isothermal reduction.
ISO 7215:2007- Determination of reducibility of iron ores
  • Reducibility may be defined as a measure of the ease with which oxygen combined with iron can be removed from natural or processed iron ores by a reducing gas, which is expressed as the rate of reduction at an atomic ration O/Fe = 0.9, relative to the iron (III) state.
ISO7992:2007 - Iron ores : Determination of reduction properties under load.
  • Method for testing the physical stability of iron ores by measuring the change in the differential gas pressure across a bed of the test portion and the change in the height of the bed during reduction under static load.
