The objective of the project was to develop a new modelling-based optimisation and quality control system for continuous casting. The concept was based on studying critical parameters affecting steel quality and finding safety ranges for them to ensure good quality in continuous casting. Several...

During research carried out in synergy by Centro Sviluppo Materiali (CSM), VDEh-Betriebsforschungsinstitut (VDEh-BFI), Cogne Acciai Speciali (CAS) and Deutsche Edelstahlwerke (DEW), operations were designed and carried out in real tundish to control steel composition and temperature, and to...

This paper aims at identifying individual and family features that represent advantage or disadvantage factors in the participation of young people to labour market. In particular, the difficult condition of the Southern Italy is analysed. First, we will compare the participation of young people...

Territorial mobility for job reasons is a topic that has a great relief in a country like Italy. Information inferable from a National Statistical Institute (ISTAT) survey on Labour Forces, on the one hand provides us with indications about the characteristics of the people involved and analyzes...

Two points have been investigated in this project about the wiping task during the hot dip galvanisation process. Firstly, the study of a casing surrounding the wiping nozzles in order to reduce the noise emission has been carried out in lab conditions, in pilot line conditions and in industrial...

This project involving Arcelor Research, CSM, BFI and RWTH was aimed at improving the inclusion removal during RH treatments. Activities were managed in accordance with the project planning. The metal throughput in the RH legs is known to increase with the lift argon flow rate injected in the...

This multinational research project aimed at the correlation of the essential parameters and to elaborate concrete process engineering measures for an improved mould heat transfer control. The research was carried out in close collaboration between the steel plants Dillinger Hüttenwerke,...

The objective of this work, performed by Cogne Acciali Speciali, CSM, VASL, and BFI, was to estimate the potential of swirling flow in casting moulds for its generation and utilisation to enhance product quality. In the tundish, investigations were made with a swirl generator at the outlet,...

Investigations on the optimisation of alloying processes in steelmaking ladles were carried out by Dillinger Hüttenwerke, IRSID, CSM and BFI. The aim was to elaborate suitable process parameters or strategies to guarantee the homogenisation of the steel melt with regard to its composition...

We are concerned with the solution of the bound constrained minimization problem {minf(x), l≤x≤u}. For the solution of this problem we propose an active set method that combines ideas from projected and nonmonotone Newton-type methods. It is based on an iteration of the form x <Superscript> k+1</Superscript>=[x <Superscript> k </Superscript>+α...</superscript></superscript>
