Abstract: Big Data is related to data sets which exceed the capacity of traditional data processing systems and enforces significant changes in the data analysis approach. Changes in the analysis of Big Data relate to: the ability to analyze large amounts of data, readiness to deal with unstructured data, and rising importance of correlations. [..] Read more

Abstract: This paper presents the results of the effect of Cr in the precipitation of carbides in nodular iron class 100-70-03. In this study was considered the average nominal chemical composition suggested by the ASTM standard and added with content between 0.5 to 3 %Cr. [..] Read more

Abstract: This article describes how to improve the tribological properties of cast iron by local strengthening by ceramic layer, directly in the casting process. The research comprised test molds with a ceramic (composite) layer. [..] Read more

Abstract: The article presents the way of improving usable properties of cast irons by producing titanate coats in founding process, introducing titanium insert directly before pouring molten metal. It is presented an innovative way to use 3D technology applying SLS method in order to obtain local reinforcement of cast iron. [..] Read more

Abstract: The blast furnace process can be negatively affected by a number of harmful elements. These may interfere with the course of the technological process, but can also increase production costs. [..] Read more

Abstract: The article presents results of studies of silicon – molybdenum cast iron crystallization process. This material is use to work in high temperatures. [..] Read more

Abstract: Directionally solidified sample of Fe-C alloy in a vacuum Bridgman-type furnace was produced under an argon atmosphere. The pulling rate was v = 83.3, 125.0 and 166.7 μm/s (300, 450 and 600 mm/h) with constant temperature gradient G = 33.5 K/mm. [..] Read more

Abstract: Production of crude steel with the help of oxygen processes will produce, according to forecasts also in the future, large portion of the world-wide steel production. In the connection with this fact the blowing systems are being further developed and improved both in case of oxygen converters, hearth furnaces and in case of electric furnaces or their combinations.

Abstract: The paper presents a study of the chemical composition and selected thermal operations on uniformity of the structure and properties of 75 mm thick cast iron (casting mould YIV). HB hardness distribution was investigated on cross-section of the samples. [..] Read more

Abstract: Three ferrous materials; Hadfield steel, high chromium white cast iron and austempered ductile iron (ADI) exhibit a similar phenomenon in which soft stabilised austenite transforms to hard martensite on the worked surface. This property is desirable in applications where toughness is required in the bulk of the component while the surface needs to be hard-wearing. [..] Read more

Abstract: High chromium iron castings have been observed to exhibit significantly varying mechanical properties. To establish the origin of inconsistencies in properties, the research was conducted in two phases. [..] Read more

Abstract: During continuous casting of steel, a centerline porosity formation frequently occurs and participates on decrease of internal quality of continuously cast billets. To avoid the centerline porosity formation, a description of casting parameters connection with centerline porosity is necessary. [..] Read more

Abstract: The behavior of nonmetallic inclusions in liquid steel results from such processes as fluctuation, adhesion and collisions between particles. In the metallurgical processes that take place in the ladle, the agglomeration based on turbulent collisions between oxide particles plays the most important role. [..] Read more

Abstract: The performed tests were focused on the mechanism of reaction of Y2O3 and Al2O3 particles with the solidification front while casting steel. The presence of oxide inclusions in steel is a consequence of precipitation and segregation processes in the CCS CCM crystallizer. [..] Read more

Abstract: Modeling the growth of nonmetallic inclusions can be realized in a number of ways. Authors worked out their own mathematical model for calculating the increase of nonmetallic phase in liquid steel. [..] Read more

Abstract: The surface tension of selected real steel grades and their wetting with alumina substrate in the temperature interval from the melting point to the temperature of 1600 °C were determined using the sessile drop technique. The effect of the major elements (carbon and chromium) on the surface properties of given steels was studied. [..] Read more

Abstract: The paper presents the influence of ceramic molds manufacturing parameters on the quality of small-scale castings produced by the lost wax method. Seven ceramic coatings were applied to the prepared model kits. [..] Read more

Abstract: In this work the solvent extraction has been carried out for the removal of iron(III) from hydrochloric acid solutions. Tricaprylmethylammonium thiosalicylate [A336][TS] and trihexyl(tetradecyl)phosphonium thiosalicylate, [PR4][TS], a thiol-containing task specific ionic liquids (TSIL) were used as extractants in this process. [..] Read more

Abstract: This paper deals with a recycling and reusing of non-conformity product during the production of magnets. Theoretical part of the paper contains general facts about permanent magnets and theirs productions. [..] Read more

Abstract: Steel has never ceased to be the most important structural material. Steel and cast steel account for more than 92% of total consumption of metals. [..] Read more
