Abstract: Metallurgical processes may typically involve many physical phenomena such as fluid flow, heat transfer, solidification, electromagnetism, chemistry, and kinetics in multi-component multi-phase systems. Permanently growing computational power and a massive shift to parallel cloud computing allow us to design multiphysics numerical simulations and thus gain a deeper insight into fundamental and technical issues.

Abstract: An effect of static recrystallization with inclusion interaction and a change of tensile mechanical properties of drawn free-cutting steel has been studied in the scanning electron microscope (SEM) equipped with a combined in-situ heating and tensile stage. The main goal of all in-situ tests was to effectively improve plasticity and optimize strength which is important for application of the final products from free-cutting steels. [..] Read more

Abstract: A modification to the Metropolis algorithm, which drives Monte Carlo (MC) simulation of grain growth, is suggested here. Though MC simulation allows for study of effects of variables on growth kinetics and growth inhibition in ways not possible by experimentation, the method has been largely limited to the understanding of these phenomena with a generic metal in mind rather than a specific one.

Abstract: Increasing demands on the surface quality of steel slabs together with demands on reduction of water consumption lead to the idea of replacing the secondary cooling zone with water or water-air nozzles by the so-called dry cooling through the supporting rollers. The paper presents the computational study into the dry cooling with the use of the solidification model for continuous steel casting. [..] Read more

Abstract: In the grinding process of steel products, considerable amounts of grinding dust are generated, polluted with coolant (oil, oil emulsions), and non-metallic material from abrasive (silicon carbide, aluminum oxide and others). Grinding sludge generated as a result of this mechanism is a valuable source of post-industrial waste containing, apart from iron, such alloying elements as: cobalt, nickel, copper, tungsten, molybdenum, and vanadium.

Abstract: The metallurgical industry is a trade where large amounts of waste are generated, including mill scale and iron-bearing sludge, which in the reduction process can be a valuable raw material for the production of sponge iron. In this publication the energy balance for such a process has been prepared and it has been shown that the electrical energy flow necessary to carry out reduction of mill scale with a CO + H2 gas solution is 17.48% of the total energy stream supplied to the process.
