Abstract: Main purpose of this article is to analyze and compare the capital structure of metallurgical industry in the Czech Republic, Poland and Slovak Republic before and during so called financial crisis and to find out an extent of impact of the financial crisis on metallurgical industries’ firms capital structure. The analysis primarily focuses on the debt ratios and covers the years from 2006 to 2010. [..] Read more

Abstract: One of the standard requirements for automotive industry suppliers within the framework of production part approval process is the evidence about capability of process. Process capability criteria are capability indices whose standard evaluation is based on the assumption of normal distribution of monitored quality characteristic. [..] Read more

Abstract: Quality of lectures and possibility for students after graduation, which is related to that is significantly dependent on level of closeness to the current techniques and technological practise. Along with the excursion to the specialized companies has important role the possibility to get known better with studied technique and technologies through models. [..] Read more

Abstract: The aim of this paper is to analyze factors which influence the European Union Allowances spot prices. This involves also the strength of the dependency. [..] Read more

Abstract: Presented paper deals with the composition of total costs of foundry casting production with special accent on electrical energy ratio participating. Typical calculation of costs is introduced with the help of industrial partner. [..] Read more

Abstract: The decision of what amount of a product to produce in a specific interval may impact seriously corporate earnings. Various methods have been used to eradicate this problem. [..] Read more

Abstract: The aim of the paper is to design the model for the industrial company’s profit optimization. The decision-making on the amount and structure of production is influenced by many constraints. [..] Read more

Abstract: For many years metallurgical plants belonged to a group of companies polluting the most the natural environment. Legislative rules and consequently realized environmental policy of the government forced companies to introduce the sustainable development principles. [..] Read more

Abstract: The development of the concept of the supply chain has resulted in a broader view of logistics. The primary goal of production logistics can be formulated as expansion of the capabilities for the implementation and reliability of deliveries with the lowest logistical and production costs. [..] Read more

Abstract: Many production processes are subject to tool wear. In this case, the process mean changes systematically and an upward or a downward trend is observed in the control chart. [..] Read more

Abstract: Many activities exist in management practice, which cannot be modeled and solved by mathematical - analytical method, but man is able successfully to solve it. For real solution of the logistic problems in metallurgy, mainly in the field of capacity planning, operative planning and production scheduling models creation, is most frequently applied the heuristic approach. [..] Read more

Abstract: Reliable knowledge of thermo-physical properties of materials is essential for the interpretation of solidification behavior, forming, heat treatment and joining of metallic systems. It is also a precondition for precise simulation calculations of technological processes. [..] Read more

Abstract: Customer relationship management (CRM) has become a key strategic tool for many companies, especially in the current competitive environment. At a time when market competition becomes sharper, building relationships with customers coming to the fore, helping companies win obtaining new customers, developing products and services to increase customer satisfaction and observe current number of customers. [..] Read more

Abstract: The process of creating knowledge components which allow preventing the formation of defects in metal products was described. Components are the result of the integration of knowledge from databases containing information on defects in castings, from publications dealing with the problems of metallurgy, and from standards and articles discussing causes of defects in metal products. [..] Read more

Abstract: This paper presents the results of the rheological analysis of selected ferrous solutions. In metallurgical processes, gradient of the dynamic viscosity parameter is an important indicator characterizing the behavior of liquid metal in the industrial aggregates. [..] Read more

Abstract: The cohesive zone is amongst the most important areas within the blast furnace. It is limited by isotherms of the beginning and the end of softening of the burden materials. [..] Read more

Abstract: Nowadays it is claimed that the silicon appears in the metal not only from the slag SiO2 reduction at the liquid phase, but also from a gaseous SiO. Presented in this paper, laboratory tests were aimed on finding the effect of temperature and MgO containing in the slag on the dynamics of the Si transition to the hot metal at the liquid phase at the time when slag lies on metal. [..] Read more

Abstract: Physical simulation of complicated phenomena in fluid mechanics is still widely used. Together with mathematical modeling it provides the necessary knowledge and information about the studied problems and thus significantly contributes to solving of design- engineering tasks . [..] Read more

Abstract: In the present work, magnetic field and behavior of electrically conducting fluid flow under the influence of the magnetic field are numerically simulated. Two sets of commercial software, ANSYS Mechanical and ANSYS FLUENT, are used for the numerical simulations. [..] Read more

Abstract: The operation of a blast furnace is characterized by simultaneous running chemical and physical processes. Hence, the influence of parameters like pressure, temperature and gas composition on the reduction behaviour of the iron bearing minerals cannot easily be presented in a simplified form, e.g. [..] Read more
