Navigating the chemical space: Sustainable metallurgy through materials informatics

/ ChemApp, ChemApp for Python, Conference /

How can we accelerate the transformation of the iron and steel industry using materials informatics? Computational thermochemistry is fundamental for the transition to sustainable metallurgy. You need to understand thermodynamics to create process models – or to discover new alloy compositions for advanced engineering applications. We face challenges such as the decarbonization of steel metallurgy […]

Constructing a Blast Furnace Diagram with FactSage – Part IV

/ Equilib Module, FactSage, Phase Diagram Module /

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 – Part III

/ FactSage, Phase Diagram Module /

In the 3rd blog post of this series related to the Blast Furnace Diagram, we at first consider the effect of including the metallic phases as solution phases instead of considering them as pure compounds, like we already did for the oxides. Then, we show how the total pressure will affect the diagram, in special

In the second blog post of this series related to the Blast Furnace Diagram, we explore some variations of the diagram constructed in the first blog post, while sticking to carbon as the only reducing agent in the system. This blog post was written in collaboration with Klaus Hack. The first diagram that we will

Constructing a Blast Furnace Diagram with FactSage 8.2

/ FactSage, Phase Diagram Module /

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,

Minimization of copper losses to the converter slag through a boron oxide addition

/ FactSage /

The loss of copper in the converting process through its incorporation to the converter slag represents a major problem in the copper metallurgy. There are two important mechanisms for this phenomenon: the physicochemical and the mechanical one. The mechanical mechanism, i.e. the mechanical entrapment of matte or of metallic copper inside the slag, is by
