Book Synopsis Thermodynamic Modeling of MgO-P2O5, MnO-P2O5 and CaO-MgO-P2O5 Systems by : Gabriel Garcia Curiel

Download or read book Thermodynamic Modeling of MgO-P2O5, MnO-P2O5 and CaO-MgO-P2O5 Systems written by Gabriel Garcia Curiel. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: "As part of a sustained effort to model and simulate the thermodynamic behavior of steelmaking slag, binary and ternary phase diagram systems have been modeled using the CALPHAD (CALculation of PHAse Diagrams) approach. The understanding, modeling and thermodynamic simulation of oxide systems including phosphorus oxide are of special importance to the steelmaking industry given requirements for steels with ever lower phosphorus contents while facing the processing of ores with increasing phosphorus content.In this project, two binary systems (MgO-P2O5 and MnO-P2O5) and one ternary system (CaO-MgO-P2O5) were modeled to extend the oxide database of the Factsage thermodynamic simulation software package. This present study is part of a broader effort conducted to develop a comprehensive thermodynamic database for the CaO-MgO-MnO-FeO-Fe2O3-Al2O3-Na2O-P2O5 / Fe Liq. system and allow the thermodynamic simulation of steelmaking processes such as dephosphorization. All available experimental data in the literature were critically assessed and a set of thermodynamic model parameters were developed to simulate reliably the experimental results within experimental error limits. The properties of liquid oxides and solid P2O5 compounds were described by thermodynamic models and standard Gibbs energy functions.The thermodynamic property of the liquid solution (or slag) were described using the Modified Quasi-Chemical Model (MQM) developed by Pelton et. al. (2000). This model allows to simulate short range ordering (SRO). Thermodynamic properties of solid solution phases are described using the Compound Energy Formalism (CEF) by Hillert (2000) which considers the crystal structure of each solid solution." --

Book Synopsis Process Modeling in Pyrometallurgical Engineering by : Henrik Saxén

Download or read book Process Modeling in Pyrometallurgical Engineering written by Henrik Saxén. This book was released on 2021-09-01. Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue presents almost 40 papers on recent research in modeling of pyrometallurgical systems, including physical models, first-principles models, detailed CFD and DEM models as well as statistical models or models based on machine learning. The models cover the whole production chain from raw materials processing through the reduction and conversion unit processes to ladle treatment, casting, and rolling. The papers illustrate how models can be used for shedding light on complex and inaccessible processes characterized by high temperatures and hostile environment, in order to improve process performance, product quality, or yield and to reduce the requirements of virgin raw materials and to suppress harmful emissions.

Book Synopsis Ironmaking and Steelmaking by : Zushu Li

Download or read book Ironmaking and Steelmaking written by Zushu Li. This book was released on 2019-08-13. Available in PDF, EPUB and Kindle. Book excerpt: Steel is a critical material in our societies and will remain an important one for a long time into the future. In the last two decades, the world steel industry has gone through drastic changes and this is predicted to continue in the future. The Asian countries (e.g. China, India) have been dominant in the production of steel creating global over-capacity, while the steel industry in the developed countries have made tremendous efforts to reinforce its global leadership in process technology and product development, and remain sustainable and competitive. The global steel industry is also facing various grand challenges in strict environmental regulation, new energy and materials sources, and ever-increasing customer requirements for high quality steel products, which has been addressed accordingly by the global iron and steel community. This Special Issue, “Ironmaking and Steelmaking”, released by the journal Metals, published 33 high quality articles from the international iron and steel community, covering the state-of-the-art of the ironmaking and steelmaking processes. This includes fundamental understanding, experimental investigation, pilot plant trials, industrial applications and big data utilization in the improvement and optimization of existing processes, and research and development in transformative technologies. It is hoped that the creation of this special issue as a scientific platform will help drive the iron and steel community to build a sustainable steel industry.
