More recently a modified stainless steels have been used to produce various structural elements that work in complex operating conditions. Stainless steel X8CrNiS18-9 (standard EN 10088-3: 2005) is the most commonly used austenitic stainless steel due to its good machinability. This steel has high mechanical and working properties thanks to a compl...

In the following paper results of the investigation of the “Bauschinger effect” are presented. It was done by model which was made in ABAQUS and observed from deep rolling simulation results of residual stresses. Later, comparison of the results are presented by variation of forces and overlapping factor. Deep rolling (DR) is a mechanic...

This paper describes a few examples of the recovery of manganese from steel slag and dust by using different technologies based on acid leaching.Reductive leaching in sulfuric acid (H2SO4) for recovery of manganese from electric arc furnace dust (EAFD) was represented. Recovery of manganese and iron was increased with increasing in the sulfuric aci...

The microscope has become a more common tool in the cement industry. Evaluation of clinker using microscopy is a powerful technique that can help improve clinker production and cement quality. The key to using the microscopy is understanding the process of clinker production namely how raw materials are transformed into clinker. These transformatio...

Basic raw materials for paper production are cellulose fibers and water. Water plays a major role in the process of cellulose and paper production and it is present in almost all phases of the cellulose fiber production process. Because of that the cellulose and paper industry is considered to be one of the largest consumers of natural resource pol...

The regulations on air quality in Bosnia and Herzegovina are based on European Union regulations and they rely on defined limits for concentrations of certain pollutants. Although the law stipulates that the public must be informed on the quality of environmental parameters in a clear, simple and easily understandable manner, this is not the case i...

Urban environments are subject to various pollutions where, among other things, acoustic pollution. Consequently, the study of acoustic pollution is an issue that is addressed in several aspects: economic, political and scientific / research.In this paper we propose a simulation model through the Matlab / Simulink software that shows the effect of ...

This paper examines the impact of charging wet and oxidized material on the quality of cast iron, quality SL20. In consideration were taken the same products obtained from 3 melts. For the production of the first melt wet and oxidized charging components in quantity of 60 % were used, for the second one quantity of 20 % of oxidizied ...

The effect of fly ash, coal dust and limestone on the properties of brick products are presented in this paper. Three kinds of clay were used to test the effect of additives. There were investigated the effect  of additives on the behaviour of clays during drying and firing (shrinkage and loss of weight), and the  properties of fired samp...
