Abstract: Metallurgical supply chain consists of raw materials miners, transport, integrated metallurgical enterprise, service centers and local distributors. The overall performance of the supply chain which is subject to disruption from the environment is dependent on performance of its links and its ability to recovery after such event or resilience, respectively.

Abstract: Metallurgy is one of the most complex industries. It integrates the experiences that our ancestors have moved for generations to better understand chemical and manufacturing processes. [..] Read more

Abstract: The article deals with possibilities of introducing innovations using new composite materials in the production and sale of precision rifle’s barrels. While other parts of weapons have undergone a number of design changes in the past, the barrel has not been altered. [..] Read more

Abstract: Target of this contribution is description of implementation and using autonomous vehicles (AGV) in metallurgy plants. Currently is trend doing focus on automatization of production processes due to degreasing costs and due to missing workers as well. [..] Read more

Abstract: The process of designing logistics systems in metallurgy in many cases depends on solution time, resources used and complexity of the problem – the efficiency of the solution. From this point of view, it is possible to divide the design methods into 3 levels, from the lowest, naive level (situational – ad hoc decision) and analogy, through application of models/analytical heuristic and simulation models to the highest level, complex-system approach, scientific level.

Abstract: Present conditions of highly competitive environment lead the owners and management of metallurgical enterprises to a strategic orientation on innovation, which is necessary for their durability and obtaining a significant market position. For efficient implementation of innovation activities, it is essential to compare with others and to look for ways to use the collected knowledge. [..] Read more

Abstract: Design and construction issues of blowing systems, lances and nozzles for high-temperature reactors is a hot issue, which addresses not only metallurgy but also other industrial sectors. In general, the problems of design and construction solutions are mainly oriented on issues of reducing the consumption of materials and energy, which ultimately affect the investment and operating costs of the aggregates.

Abstract: The steel casting temperature is defined as liquidus temperature plus the superheat temperature. In practice, it is the temperature measured in the tundish during the continuous casting of steel. [..] Read more

Abstract: The research work is a part of a larger study on identifying distribution of microparticles in the model liquid, which flows through a model of the tundish. Model (physical) testing is aimed at qualitative (based on visualization of the process) and quantitative assessments (performed by using the Abakus® Mobil Fluid laser microparticle counter).The article presents methodology on preparing microparticles for research tests and research test findings performed by using a laser microparticle counter.

Abstract: Current computational IT techniques allow to compute large complex multi-physical models and come up with a real-time solution. Due to this fact, a thermo-mechanical model for continuous steel casting can be created and used as a real-time crack prediction tool. [..] Read more

Abstract: Rheological properties (dynamic viscosity, flow curves) of selected Fe-C-O-Cr alloys were experimentally investigated with the use of a high-temperature rotating viscometer Anton Paar FRS 1600. The viscosity of concerned alloys was measured during cooling at a rate of 2.5 °C/min. [..] Read more

Abstract: Quantitative methods for determining the contamination of non-metallic inclusions (NMI) steel can be divided into metallographic, physicochemical or chemical. The quality control of steel in the metallurgical industry mostly uses a method in which their microstructure is observed on undigested destruction. [..] Read more

Abstract: Modern devices for continuous casting (cc.) of steel - despite the shape of cross-section of cast billets, are equipped with electromagnetic systems for stirring liquid core inner the solidifying steel shell. Depending on the grade of cast steels, requirements for isotropy of chemical composition and properties along transverse and longitudinal cross-section of cc. [..] Read more

Abstract: The vast majority of metals and alloys used in technical practice are produced from a liquid state - a liquid metal. A most important phase transformation at steelmaking process is crystallization of steel (phase transformation of liquid steel from liquid to solid state) and process of own solidification of steel. [..] Read more

Abstract: During the casting of heavier ingots, internal porosity occurs during solidification due to shrinkage of the cast metal. Porosity, or non-metal-filled areas, is up to several centimeters inside large ingots. [..] Read more

Abstract: Investigation results for segregation in terms of chemical compositions of various ordinary and refined ultra-low carbon FeSi75 ferrosilicon fractions have been presented. The subject of investigations was ferrosilicon obtained under industrial conditions after mechanical shredding and separation on 10-60 mm, 3-10 mm and 0-3 mm sieves. [..] Read more

Abstract: Blast furnace gas, which is created as a by-product during the ironmaking, belongs to the less valuable fuels due to its low heating value. Due to BF gas parameters (high amount of gas and high content of CO), it is used as an energy source for the preparation of preheated air in the stoves or for the heating of industrial furnaces. [..] Read more

Abstract: In precise casting, the important parameters of multi-layered ceramic forms are their thickness and porosity. Defects, e.g. [..] Read more

Abstract: Production of innovative types of steel and other metallic materials requires the composition to contain, in addition to iron, other chemical elements that influence desired properties of the alloy. Alloy additions are mainly introduced due to the use of appropriate ferroalloys in the production process. [..] Read more

Abstract: The article presents a method of description the Al2O3 oxide layers structure observed by scanning microscopy. Unusual geometrical features of the structure enforce the use of non-standard techniques for their description. [..] Read more
