Formal concept analysis applied to the prediction of additives for galvanizing process
Croatian Metallurgical Society, 2010Co-Authors: J. KlimešAbstract:Formal concept analysis is a new mathematical approach to data analysis, data mining and to discavering patterns in data. The result of the application of the formal concept analysis method to the behavior of the galvanizing of Rimmed Steel is presented. Effects of additives in the galvanizing process have been correlated to the chemical element properties of the additives. This model may also help to design new alloys as additives in the galvanizing process

Rezultati primjene metodologije formal concept analize na ponašanje galvaniziranih čeličnih naplatake su dani. Efekti dodataka u procesu galvanizacije su u korelaciji sa svojstvima kemijskih elementa aditiva. Taj model može također pomoći u dizajniranju novih legura kao aditiva u procesu galvanizacije

Segregation of Semi-killed Steel
東北大學選鉱製錬研究所, 2010Co-Authors: 森永 孝三Abstract:Comparisons were made of the chemical compositions of ingots, containing less than 0.12% carbon, produced from Rimmed and semi-killed Steels after being rolled to billets and sheet bars. Steel slubs to be used as ship building material containing 0.17～0.27% of carbon were made from Rimmed, semi-killed and killed Steels and their chemical compositions were studied. From the results obtained, we confirmed, though had already been confermed, the following facts : segregation was great in 1/3～1/4 of the head of the Rimmed Steel ingots. In the killed Steel, because the shrinkage pipe was cut off, the yield was lowered, but in the semi-killed Steel, if we paid attention to deoxidation degree, the segregation was less, and in the sheet bar and the ship-building Steel plate, the yield was raised

Progress of the Cold-rolled Steel Sheets in Press Formability
東北大學選鉱製錬研究所, 2010Co-Authors: 吉田 浩Abstract:A great progress has been made in the manufacture of cold-rolled Steel sheets during this decade to meet the demands of car industry and many others. To manufacture the Steel sheets suitable for press formability, the deep drawing, stretching, expanding and bending properties of the sheets were studied. In addition, the shaping property of the sheets has recently been recognized as one of important factors. Furthermore, in the case of Rimmed Steel sheets, non-aging property has been considered also important. The author outlined these problems in connection with various metallurgical viewpoints, namely, composition, internal defects, second phase particles, grain size, crystallographic anisotropy, etc., and reported how the operational techniques concerning these problems had been developed and how the plants at the Kawasaki Steel Corporation had been working

NDT-Toolbox (Non Destructiuve Testing Toolbox) : Sustainable Bridges Background document SB 3.16
EPFL Lausanne Switzerland, 2007Co-Authors: Helmerich Rosemarie, Bässler Ralph, Buhr Birgit, Holm Göran, Krüger Markus, Niederleithinger Ernst, Brühwiler EugenAbstract:Non-Destructive testing (NDT) is an appropriate technique to assess the bridge condition without damaging the bridge. In general, during the measurement procedure, the railway traffic is not interrupted, since the accessibility from one side is sufficient for numerous echo-methods. The NDT-toolbox describes the available NDT-methods and explains application, physical background, limitation, required equipment, time consumption and complexity of the methods on a one-page information. Besides the state of the art, the toolbox informs also, which methods where enhanced and applied within the project Sustainable Bridges (SB 2003-2007). The NDT-toolbox presents methods for application to bridges made of concrete, Steel, including old Steel as puddled (wrought) iron or Rimmed Steel, masonry as well as soil and foundations. For the different materials, the same basic physical principle results in different application with special well-adapted sensor types. The basic physical principle groups of the NDT-methods are: Visual inspection Simple inspection Electromagnetic methods Acoustic methods Radiographic methods Thermal inspection In tables of the SB-ICA guideline (Helmerich et al. 2007), all NDT-methods (annex 3) are linked to appropriate defect types according to the defect catalogue, attached as annex 2 to this guideline. Vice-versa, the inspector may presume a crack or a hidden defect and via links in tables of the SB-ICA guideline he will find appropriate NDT-methods, useful for further investigation of the defect.EC Sixth Framework ProgramSustainable Bridges – Assessment for Future Traffic Demands and Longer LivesTIP3-CT-2003-001653
