Original scientific paper The properties of metallurgical cokes obtained in a laboratory from pure coal and with additives (light atmospheric residue of oil distillation and coal tar pitch) after heat treatment to 1600 °C were investigated. Changes in the basic characteristics (density, moisture, ash, metal and sulphur contents) were examined. Crystallographic parameters (crystallite size, Lc a...

Abstract—This study presents an inverse analysis for predicting the thermal conductivities and the heat flux of a high-temperature metallurgical reactor simultaneously. Once these thermal parameters are predicted, the time-varying thickness of the protective phasechange bank that covers the inside surface of the brick walls of a metallurgical reactor can be calculated. The enthalpy method is us...

Several numerical approaches have been proposed in the literature to simulate the behavior of modern blast furnaces: finite volume methods, data-mining models, heat and mass balance models, and classical thermodynamic simulations. Despite this, there is actually no efficient method for evaluating quickly optimal operating parameters of a blast furnace as a function of the iron ore composition, ...

A literature review of studies and researches has been attempted in the field of dissimilar metal welding. Dissimilar metal welds have numerous industrial applications in area of thermal power generation, chemical, petrochemical, automobile, aerospace industries and nuclear plants etc. The purpose of this paper is to review: (a) Dissimilar metal welds, their Metallurgical and Mechanical aspects...

Within the framework of the European Metrological Research Program (EMRP) IND04 MetroMetal 'Ionizing radiation metrology for the metallurgical industry', joint research carried out by 14 metrological institutions from countries within the European Union and the company ENVINET, questions concerning the determination of radioactivity in samples relevant to the metallurgical industry were resolve...

The ability of laser-ultrasound to monitor in real-time metallurgical transformations is reviewed in this paper. Although the technique is appropriate for online industrial materials characterization, this paper addresses laboratory characterization of metallurgical transformations. Examples are presented on the real-time sensing of grain size and grain growth, phase transformation and recrysta...

B.Gajdzik, Silesian University of Technology, Faculty of Materials Science and Metallurgy,Katowice, Poland On the basis of report analysis which presents situation in metallurgical sector after 2008 the range of changes implemented in management of metallurgical enterprises was characterised. A defi nition approach to crisis management was suggested as the process when the enterprise is managed...
