Constructing a Blast Furnace Diagram with FactSage – Part IV

In order to reduce the CO2 emissions caused by the iron & steel industry, there have been initiatives in the last decades to substitute reductants based on carbon by the use of H2 as a reducing agent. These initiatives go from the direct injection of H2 at the tuyeres of the blast furnace [1, 2] […]

Constructing a Blast Furnace Diagram with FactSage 8.2

The so-called blast-furnace diagram describes which phases are stable in the different regions of the blast furnace, depending on the conditions of temperature and of the atmosphere inside the furnace[1]. It is basically a phase diagram, where the volume fraction of CO is represented on the X-axis and the temperature is represented on the Y-axis,
