Abstract: The paper characterizes the tasks of the selected logistic subsystem in the area of the enterprise operations. The main aim of the study is to identify and analyse selected tasks of management of the supply subsystem in the Enterprise X operating in the foundry sector.The theoretical approach to the supply subsystem in the systematic logistics concept was presented.

Abstract: The paper describes practical application of the 80/20 rule (also well-known as Pareto´s rule) in heat treatment processes of metallic materials. The principle of the 80/20 rule is based on the study of Italian economist and sociologist Vilfredo Pareto. [..] Read more

Abstract: The contribution deals with the classical specification of phase calculations in a metallurgical company and compares them with modern calculation methods. It briefly describes the methodology of these calculations, its advantages and deficiencies. [..] Read more

Abstract: The paper characterizes the tasks of the selected logistic subsystem in the area of the enterprise operations. The main aim of the study is to identify and analyse two tasks of management of the supply subsystem in the Enterprise X operating in the foundry sector. [..] Read more

Abstract: The need for decision-making is related to management, constituting the substance thereof. Management means the wilful, purposeful influencing of a certain process, phenomenon or situation in order to achieve the required outcome or objective.Therefore, we make decisions in the case of a deviation from the required status and if the achievement of the objective is at risk, or when we get into a situation when the objective can be achieved in several different ways.

Abstract: The main purpose of this paper is to determine the concentration level of the metallurgical industry in Europe. The first part presents the overall situation in this sector in the 2007-2014 period. [..] Read more

Abstract: In the paper, the quality research of the steel bars produced by chosen Polish metallurgical enterprise was presented. The chemical composition of the steel grade 1006 produced in this enterprise was determined. [..] Read more

Abstract: Metallurgical and foundry enterprises in the long term a shortage of qualified graduates of metallurgical specialties. The lack of trained human resources leads to a reduction in the competitiveness of Czech companies, therefore, pay great attention to vocational education. [..] Read more

Abstract: It is more and more difficult for companies and firms to survive in the highly competitive environment at the present. This is why they try to find ways to achieve competitive advantages, which is associated with investments in innovative technologies or information technologies. [..] Read more

Abstract: The paper deals with a comparative analysis of reducibility of metallurgical sinter typical with high and low basicity. The samples were performed at 950°C of reduction test according to ISO 4695 which characterized their reducibility potential in CO atmosphere. [..] Read more

Abstract: Coke is one of the basic energy sources in the blast furnace process. Its quality essentially then determines the course of the blast furnace process. [..] Read more

Abstract: In the article there is an analysis of OEE (Overall Equipment Effectiveness) and EPEI (or EPEx – Every Product Every Interval) indicators of medium size rolling mill plant in one of the raw materials steel mills. Analysis of OEE and EPEI covered period of 12 months. [..] Read more

Abstract: Fuzzy logic controllers serve the same function as the more conventional controllers, but they manage complex control problems through heuristics and mathematical models provided by fuzzy logic, rather than via mathematical models provided by differential equations. This is particularly useful for controlling systems whose mathematical models are nonlinear or for which standard mathematical models are simply not available, such as in metallurgy. [..] Read more

Abstract: This paper presents the results of preliminary low-cycle fatigue tests of 1.2344 tool steel, used to make forging tools for work in higher temperatures. Based on macro- and micro-structural studies and numerical simulation of industrial forging processes, the conditions for performing laboratory fatigue tests were determined. [..] Read more

Abstract: The paper concerns the possibility of the use of modern non-contact measurement techniques in a die forges, like application a measuring arms with integrated linear scanners to analyze wear of forging instrumentation. In particular, to assess the progress of tool wear forging - punch used in the second forging operation of the forging type cover. [..] Read more

Abstract: The aim of this paper is to describe adaptive control of the heating furnace with the utilization of PID type regulator. Advantages of the proposed adaptive regulator are changeable parameters of the system and/or changeable desired quantity of regulation circuit. [..] Read more

Abstract: Industry 4.0 Concept is current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, the Internet of things, Big Data, cloud computing and more. [..] Read more

Abstract: 5S method belongs to a group of tools comprising Lean Manufacturing, the proper implementation of which makes it possible to standardize production operations, improve the quality of manufactured products and systematize production and organizational operations which have a direct impact on the effectiveness and capabilities of the manufacturing process. The aim of the article is to present practical aspects related to the implementation of 5S method in the production enterprise which executes casting operations for the automotive industry. [..] Read more

Abstract: The article presents the use of Cobb-Douglas production function (C-D model) to analyse the impact of two basic factors of production: capital and labour of its size in Polish steel industry. Paul Cobb and Charles Douglas wrote the function as: P = a Lα C1-α (where P is the production of L - labour, C - capital). [..] Read more

Abstract: Circular Economy is a current priority of the European Commission's economic policy. In production processes, also in the metallurgical industry, this involves application of the Best Available Techniques (BAT) and support of innovative industrial processes and practices that enable Industrial Symbiosis - waste or by-products from one industry become raw material for another, which is particularly important in the case of critical raw materials.An example of a Metallurgical Industrial Ecosystem is provided by ZGH Bolesław Group, the main producer of Zinc and Lead in Europe.
