Process transitions are common in the iron and steel industry. Our investigation shows that more than 50% of catastrophic process failures in continuous steel casting operation are related to abnormal operations during the process transition period. As a multivariate statistical (MVS) analysis tool, Multi-way PCA (MPCA) is applied in this paper to monitor one important process transition in the...

This paper describes an industrial application of case-based reasoning (CBR) in the aluminium die-casting industry: the setting of parameters of a pressure diecasting machine for a specific die. As well as describing the application, the paper shows how the system has evolved. The use of cases has given the system a flexibility which has enabled it to be used in ways that were not foreseen at t...

The most frequent and expensive cause category of compensable loss is manual material handling (MMH). Casting workers who handle oxygen (O2) cylinders manually are at risk for work-related musculoskeletal disorders (WMSDs). The aim of this study was to assess manual handling of O2 cylinders by casting workers and to implement ergonomic intervention to reduce the risk of musculoskeletal disorder...

This research deals with the development of Autonomous Distributed Manufacturing Systems (ADiMS) Concept and an example of its application in the casting industry. ADiMS is a manufacturing system concept developed to increase the flexibility of the system. In ADiMS, each of the manufacturing system elements (holon) had been modelled as an intelligent element with the result that each element ha...

The merit of the project consists in the interdisciplinary joining of the knowledge in the area of light metal alloys, including Al and/or Mg, in the area of materials processing connected with the entire scope of problems connected with manufacturing of products and their elements, in the area of the automated low-pressure die casting, and also in the methodology of structure and properties as...

background: to establish a balance between work (physical exercise) and human, the aerobic capacity (vo2max) could be used as a measure. assessing heart rate in association to physiological symptoms is the most commonly used tools for the assessment of fatigue during physical exercise. this study aimed to investigate the association between the aerobic capacity and the heart rate of workers fro...

Aluminum alloys show a low weight, relatively high specific strength, good corrosion resistance in neutral environments and high electric and thermal conductivity. It makes them of interest for production of various functional components in aerospace and automotive industry. Wrought alloys generally have good formability and they are processed by common technologies, such as extrusion, forging,...
