Abstract: Economics of blast furnace process, which determines the total cost of production, is one of the most important elements of management in steelworks. In the article the coke consumption from different manufacturers in the blast furnace process in chosen metallurgical plant over five years was presented. [..] Read more

Abstract: This article focuses on combination of the Value Stream Mapping and computer simulation within metallurgy supply chain optimization. The authors´ aim is to build up a conceptual model and verify it so that impacts of supply chain optimization by means of lean concept could be properly identified. [..] Read more

Abstract: Mechanical characteristics of the creep-resisting alloy IN 713 LC depends on its content and material purity, furthermore on the structure and structural non-homogeneities. Significant influence on the material properties, for its usage, has the way of crystallization, modification of the grain structure secured by technological setup of the casting tree and special directed insulation of the tree.The aim was to realize the tests on the samples to achieve definition of casting process and sequential detail grain structure study of the directed solidified castings with higher mechanical properties at higher temperature. [..] Read more

Abstract: The productivity of the Supply chain management (SCM) system is strongly influenced by the stability of either the production or the delivery processes. Commonly, unpredictable customer demand is understood as the root cause of instability. [..] Read more

Abstract: Metallurgical production in blast furnaces is characterized by its high energy intensity and complex nature of production. Pig iron as input raw material also contains various other elements. [..] Read more

Abstract: Production of metallurgical enterprises requires high costs and the production process in blast furnaces is among the most complex manufacturing processes. Blast furnace process is energy intensive and, since the prices of input raw materials have been constantly rising, companies must look for possible ways how to reduce their costs. [..] Read more

Abstract: Financial performance is a random process which could be decomposed in the particular indices. Often the influence function is of a non-linear form. [..] Read more

Abstract: Companies’ effort to work effectively, associated with the implementation of lean philosophy principles has changed significantly all companies processes within last decade. There has been a huge progress since the day when principles of lean manufacturing were introduced by Toyota. [..] Read more

Abstract: Although the requirements on quality of products are increasing, most companies still pays little attention to product quality planning. Furthest in this direction they are automotive suppliers, which include most of metallurgical companies, which use quality planning methodologies developed for this industry area and which must within the framework of production part approval process submit evidence about successful products and processes quality planning. [..] Read more

Abstract: The results of the risk assessment in the logistics processes at the metallurgical industry are presented in this article. The paper contains a comparison of safety systems based on the PN-EN 18001 and OHSAS. [..] Read more

Abstract: The conditions of enterprises operation in steel sector for the globalization era are constantly changing. In line with its ambition to strengthen its competitive position it is necessary to look for sources of competitive advantage. [..] Read more

Abstract: The effort to long-term prosperity of companies and the achievement of high productivity is the goal of the enterprise managers for decades. More than 100 years ago the first effort to introduce scientific practice in corporate governance can be traced and through them achieved the maximum productivity during the elimination of wasting of any kind. [..] Read more

Abstract: The requirements of technical practice for the quality of university graduates continue to grow. The quality of teaching and the related working possibilities of students after graduation largely depend on the degree in which the curriculum corresponds with techniques currently used in practice. [..] Read more

Abstract: This paper describes the advanced positioning technology - RFID, GPS and GSM focusing on their use in data collection, processing and modification to optimize decision-making processes in logistics in metallurgical conditions. The paper outlines the importance of logistics distribution and logistics processes in terms steelworks with links to other metallurgical processes. [..] Read more

Abstract: The paper deals with the optimal layout of smelting’s sequences in continuous steel casting device (CCM) using K-Means clustering methods as well as using fuzzy clustering. This optimization is trying to achieve a positive effect to the mold’s durability. [..] Read more

Abstract: The article presents applied solutions in the range of supply chain structure of metallurgical products required in machinery and equipment manufacturing taking into account the realisation of contracts to order in selected machine-building enterprises. The study undertakes issues concerning different types of inter-organisational relationships and determinants for the effective implementation of supply processes in a selected company. [..] Read more

Abstract: In the validation and evaluation of conformity between customer requirements and actually achieved quality of the products is always necessary to take into consideration two contradictory requirements. The first of them is the requirement for the most accurate and highest quality measurements or inspection. [..] Read more

Abstract: The article presents efficiency and productivity analysis of US metal industry in 2006-2014. The main purpose of this paper is to compare the efficiency of 6 sectors manufacturing metal products in US. [..] Read more

Abstract: The aim of this article is to present the situation of the steel industry in Poland, and to show the impact of economic conditions on this sector. The study covered the period from 2006 to 2013. [..] Read more

Abstract: Alloys that have lamellar structures, e.g., pearlitic steel, are widely used in practice. Nowadays, perlitic steel wires for tyre cords, springs and ropes are studied extensively at our laboratory of wire drawing. [..] Read more
