Abstract: The present state of energetic management is facing several issues, including force to lower production power consumption, to increase efficiency of the production and among others to eliminate financial penalties for energy spikes drawn from the power grid. Especially financial penalties can be eliminated keeping power consumption of the production line in specific boundaries and has immediate financial effect. [..] Read more

Abstract: The aim of this article is to present the relationship between the foreign trade in iron ore in European Union countries and the overall economic situation. The study covers the period from 2001 to 2017. [..] Read more

Abstract: This paper is dedicated to the problems of servitization and the possibilities of its application in metallurgy. It aims to identify the selected Czech steel manufacturers’, steel processors’ and casting manufacturers’ awareness of the servitization concept and to analyse the possibilities of its application at these companies. [..] Read more

Abstract: Every company, including metal industry company, forces every day with the problem of the quantity of ordered and stored materials used in production processes. The quantity depends mainly on the cost of their ordering and storage as well as technological requirements of the production process. [..] Read more

Abstract: The objective of this article is to compare and evaluate the most suitable washing technology of cleaning and degreasing machined parts after CNC machining, based on analysis of technological and economic criteria. Based on these criteria, costs of low-quality products are eliminated, production costs of manufactured parts are reduced, and the enterprise reaches higher profit. [..] Read more

Abstract: Present fast development of automation technology and its optimal implementation in control of metallurgical processes requires trained specialists who will be able to manipulate with it and also design and set it up. That requires special practical training of university students. [..] Read more

Abstract: The paper is focused on electrical and electronic waste and the associated waste. The generated amount of electronic waste, including mobile phones, supports the search for an efficient way to process this waste. [..] Read more

Abstract: Net working capital management is of key importance for the development of every enterprise. Net working capital directly affects the income, costs, profit and financial safety of business units. [..] Read more

Abstract: The article presents structural changes of blast furnace coke. Mass proportions of the crystalline phase of coke before the blast furnace process and after heat treatment are presented. [..] Read more

Abstract: The article presents the results of research related to the assessment of the impact of the use of selected lean tools on the level of safety in foundries. The factor analysed is the registration of potentially dangerous accidents and events in the foundry. [..] Read more

Abstract: The paper deals with steel surface treatment, blackening and phosphating of zinc and a production line that will perform these treatments. With the help of simulations were validated its various options and variants in which is able to work and produce. [..] Read more

Abstract: The chimney gate valve is widely used in the metallurgical industry as a control element in fume extraction systems of the furnace chamber. However, its flow characteristics are not appropriate for controlling this flow. [..] Read more

Abstract: Ergonomic rationalization of workplaces and the creation of optimal conditions for work performance have a positive impact on worker satisfaction, thereby enhancing efficiency and productivity at work and reducing employee turnover. Therefore, for manufacturing companies where human labor is the dominant factor, efficiency gains are very important for ergonomic rationalization. [..] Read more

Abstract: A brief overview of the status of European steel mills is the basis for the possibility of incorporating the Vroom-Yetton-Jago model in metallurgy. Not only in the Czech Republic, the steel industry is heavily influenced by the emerging applications of Industry 4.0, which will lead to new production standards and, at the same time, the pressure of global competition will increase.

Abstract: The subject of this work is a production line in an anonymous enterprise. It is a production process of forming U-profiles of different thickness and structure. [..] Read more

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. [..] Read more

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. [..] Read more

Abstract: The paper deals with the study of phase transition temperatures of pseudoquaternary Fe-C-Cr-O based alloys from RT up to 1600 °C. The knowledge of phase transition temperatures is crucial for application purpose and also for basic research related always closely to the applications. [..] Read more
