ISO 7992:2022 PDF Download

An approach for calculating the reduction under load of iron ores used as blast furnace feedstocks is described in ISO 7992:2022. This standard's objective is to evaluate the structural stability of iron ores under conditions of reduction that are comparable to those in the reduction zone of a blast furnace.

Both lump ores and hot-bonded pellets, which are frequently used as blast furnace feedstocks, are covered by the standard. According to the procedure outlined in ISO 7992, the iron ores are loaded while being reduced, and the amount of reduction that results is then measured.

This standard offers a comparative way to assess the stability and appropriateness of iron ores for blast furnace operations by calculating the reduction under load. The outcomes of this test can be used to evaluate how iron ores perform and behave in the reduction zone, assisting in blast furnace process optimisation and ensuring reliable and effective production of iron and steel.
