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:
During the production of plain carbon steel from hot metal and/or scrap considerable amounts of dust-laden off-gases are produced. In de-dusting of these off-gases considerable amounts of fine grained residues are produced, which have to be stored, transported and handled. [..]

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:
This paper deals with results of plant experiments aiming at achievement of low oxygen concentrations and high micro-cleanness during steel treatment for energetic industry on units of secondary metallurgy. Plants heats were aimed at analysis of influence of slag-making agents, wear of the lining, modification of inclusions, choice of mode of their out-stirring by the help of EMS and Ar blowing. [..]

Abstract:
The course of the blast furnace process can be significantly affected by many harmful substances. Some elements may affect the technological parameters of the blast furnace process, others may fundamentally disrupt steelmaking processes following the production of crude iron. [..]

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. [..]

Abstract:
Based on the non-stoichiometric Gibbs free enthalpy minimization algorithm (FEM), an equilibrium physicochemical model of the ferrosilicon FeSi75 smelting process has been elaborated where the influence of process parameters was determined. In the above model in the submerged arc furnace, the basic parameters are temperatures of the upper and lower reactors and a fraction of the reducer in reaction mixture expressed by the molar ratio .

Abstract:
Thermo-analytical methods are commonly used for phase transformation temperature identification in a lot of science and industrial applications. Currently, there are most frequently methods based on very small samples analyses like a differential scanning calorimetry (DSC) and/or a differential thermal analysis (DTA) realised for various materials mostly in combination with a thermo-gravimetry (DSC/TG; DTA/TG respectively).

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.
