Abstract: Nowadays sustainability plays a crucial role in managing the companies. Metal industry organizations implement a variety of innovations paying special attention to sustainability, both in production and materials area. [..] Read more

Abstract: Vision Industry 4.0 also includes a digital factory. Its core is based on the ideas of cyber-physics systems, models using all available modelling methods, artificial intelligence that includes fuzzy systems, artificial neural networks, expert systems, etc.This concept is also beneficial to the metallurgical industry, where many systems have been developed, although not under the conception of Industry 4.0, in the past.

Abstract: The article describes and analyzes specific approaches to calculation of life cycle costing (LCC) as a part of Life-cycle Cost Analysis (LCCA). LCCA is an approach to assessment the most cost-effective alternative in comparison to other alternatives when each of them is equally suited from a technical point of view. [..] Read more

Abstract: The paper presents the main findings indicating relevant technologies for the development of the sector of production and material processing in Śląskie Region, Poland. The findings are results of analysis carried out by the observatory of material technologies operating within the framework of a network of specialist regional observatories in the region.

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. [..] Read more

Abstract: The presented paper is focused on the experimental study of the surface properties of selected commercial steels (three alloys based on Fe – C – Cr). The surface tension of given steels and their wetting with alumina substrate in the temperature interval from the melting point to the temperature of 1600 °C were determined using the sessile drop technique. [..] Read more

Abstract: In this paper, the dependencies of density (ρ), surface tension (σ), and average wetting angles on temperature were investigated at three Fe - C - Cr model alloys where chromium content ranged from 0.92 to 4.76 wt%. All measurements were performed by sessile drop technique in a resistance furnace at temperatures from melting point up to 1600 °C. [..] Read more

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: Based on the equilibrium model with two isothermal reactors, the influence of CaO and MgO oxides on the ferrosilicon process in the submerged arc furnace was determined. The influence of addition of CaO and MgO oxides in the feed mixture on the SiC carbide phase formation, the contents of Ca and Mg elements in the chemical composition of the FeSi alloy as well as the efficiency of the carbothermal reduction process have been determined..

Abstract: The problem of the furnace slag penetration into the ladle is inseparably connected with the process of steel furnaces tap holes closing and opening. We are talking about the so-called slag free tapping. [..] Read more

Abstract: In the paper the author presented forecasts of steel production size for Poland. The forecasting methodology proposed by the author was two-pronged. [..] Read more

Abstract: Computer-aided image recognition methods are non-invasive, easy to implement and quick to calculate defects detection methods. They seem to be a promising method for investment casting applications – defects can be detected in individual incestment casting processes, reducing the costs caused by defective castings.As part of the research, defects have been defined and described in wax models.

Abstract: Introduction of argon to the bath is a commonly used secondary metallurgy treatment. The most economical technique of secondary metallurgy is the ladle process at the ladle furnace station. [..] Read more

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. [..] 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 article presents the results of research of iron content (II) and iron (III) in mill scale. The total content of iron was marked by the absorptive atomic spectroscopy, however the analysis of Fe content (II) and Fe (III) was carried out with the spectroscopy methods. [..] Read more

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: Due to the specific requirements for monitoring processes and products in the aircraft industry, non-destructive testing (NDT) is increasingly used in combination with advanced statistical analysis.The paper presents the results of research aimed at determining the quality of wax models and multi-layered ceramic forms, used for precise casting of critical parts of aircraft engines. Studies on the shape and dimensions of wax models and ceramic moulds were made by 3D scanning using the GOM ATOS CORE 200 scanner. [..] Read more
