Dry reforming of methane (DRM) has been investigated under an electronactivated catalytic bed in a thermo-electrical reactor. The main objective of this work was to investigate what the impact of the electrical current on the conversion of methane is. The combination of thermal and electrical energy allowed achieving higher conversions for both reactants at temperatures varying from 850–950°C. ...

This paper presents the model, solution method, and system developed and implemented for hot rolling production scheduling. The project is part of a large-scale e€ort to upgrade production and operations management systems of major iron and steel companies in China. Hot rolling production involves sequence dependent setup costs. Traditionally the production is scheduled using a greedy serial me...

Over the last four years efforts have been devoted towards the development and validation of mechanical test result models relating to a range of alloy steels. Several neural-network based models have been developed, two of which are related to the mechanical test results of Ultimate Tensile Strength (UTS), Reduction of Area (ROA), Elongation, etc. The ultimate aim of developing these models is...

Meeting customer demands for higher quality is a major business focus in the development of steel products. The quality of steel can be increased in many ways, for example, by improving its toughness or its resistance to atmospheric corrosion or by making thinner sections without sacrificing strength. As the largest steel supplier in the world, Nippon Steel Corporation (NSC) receives many kinds...

At BAM, the Federal Institute for Materials Research and Testing, a group of scientists develops NDTapplications based on GMR sensor technology. In particular, the knowledge gained in the field of automated testing systems based on the magnetic flux leakage (MFL) were combined with GMR sensors to achieve high resolution testing of ferromagnetic materials. In cooperation with Europe’s second lar...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The objective of this publication was to present the results of prognoses for steel production volume in the world. This work was created on the basis of statistical data. The volume of total steel production in the world from 2000 to 2015 was used in order to create the prognosis. T...

The present paper presents the algorithmic solution, based on an Ant System metaheuristic, of an industrial production–inventory problem in a steel continuous-casting plant. The model proposed is based on an objective function, the aim of which is to find the most profitable production schedule of the steel billets. Furthermore, the model takes into account the relevant parameters of the finite...

The ferrochrome alloy is produced by electric arc melting of the mineral chromite (FeCr2O4). It is largely used for the production of stainless steels. Increasing the amount of chromium content in the steel allows for increased corrosion and oxidation resistance. Other alloying elements, such as nickel (Ni) or molybdenum (Mo), aid in making the steel more passive and increasing its stainless pr...
