Navigating the chemical space: Sustainable metallurgy through materials informatics

/ Alloy and Material Design, ChemApp, ChemAppPy, Equilib Module, Process Metallurgy, Process Metallurgy, Uncategorized /

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 III

/ Phase Diagram Module, Process Metallurgy /

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

A SimuSage Process Model for the Oxidative Stage of the TSL Process

/ Process Metallurgy /

In recent years, there has been a continuous societal and industrial effort to promote the so-called „circular economy“. According to this paradigm, for producing engineering materials in general, and metals and alloys in particular, the chemical elements which are presently necessary in our economy should not be extracted from the so-called primary ores but instead

A Simusage Process Model for the Iron Blast Furnace

/ Process Metallurgy /

Harvey and Gheribi[1] developed a thermochemistry-based model for the iron blast furnace. In their work, the corresponding process model was developed with a flowsheeting approach based on the connected local equilibrium reactors method, which was implemented using SimuSage, one of the very successful members the GTT’s product family. The model was constructed based on the

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

/ FactSage, phase diagram module, Process Metallurgy /

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
