The problem of the prediction of a critical situation during continuous casting in common steelmaking practice is faced through different traditional soft–computing techniques: the task is to divide the data in two classes corresponding to good and bad casting behaviour respectively. Moreover, a novel algorithm, the Model–based method, is presented. The performance obtained by the different tec...

The foaming process is an important part of the electric arc furnace (EAF) steelmaking process. It can promote thermal efficiency and reduce refractory consumption. FeO a key material used during Unlike with other components in forming slag, amount be controlled by oxygen or carbon injection. Therefore, adjusting content most economical mode adopted for EAFs In this study, influence on physical...

The iron and steel industry is one of the world's largest industrial emitters greenhouse gases. One promising option for decarbonising hydrogen direct reduction (H-DR) with electric arc furnace (EAF) steelmaking, powered by zero carbon electricity. However, to date, little attention has been given energy system requirements adopting such a highly energy-intensive process. This study integrates ...

In the last years, reduction of CO2 emissions from steel industry has been great importance. Carbon capture, oxygen blast furnaces and top gas recycling technologies, among others, have deeply studied as low carbon solutions. this paper, a novel integration capture power to technologies in steelmaking is presented. Green hydrogen via proton exchange membrane (PEM) electrolysis methyldiethanolam...

Production of overall CO2 emissions has exhibited a significant reduction in almost every industry the last decades. The steelmaking is still one most producers worldwide. processes and facilities used at steel plants, such as blast furnace electric arc furnace, generate large amount waste heat, which can be recovered meaningfully used. Another way to reduce number low-quality products which, d...

Electric arc furnace (EAF) steel bottom-blowing can effectively improve the temperature and composition uniformity of molten pool during smelting process. To explore effect molten-steel characteristics on at various stages smelting, we divided process EAF into four stages: melting stage, early decarburization intermediate ending stage. The numerical simulation software ANSYS Fluent 18.2 was use...
