The project objectives are to characterise gas stirring during ladle metallurgy using vibration and camera sensors, and to develop innovative signal processing for obtaining representative indices, used as input into online metallurgical models for adjusting and improving the process. DH and...

The main results of the development are innovative systems for an online and accurate measurement of the concentration of COx and 02 at OG system of BOF converter. Based on this measurement, it is possible to develop models of the gas extraction system to optimise control over the OG system,...

More stringent customer requirements and the need to increase productivity are two of the numerous reasons that push steelmakers to deliver higher surface quality strips. Even with the recent process improvements, the strip surface is not yet fully under control. To support a better control of...

Online detection of defects or in homogeneity based on oxides, organic and salt contamination, is a key issue for steel industry. Spectrometric techniques in ultraviolet (UV), visible, near infrared and mediumand long-wave infrared (MWIR and LWIR) have proved in laboratories their capacities to...

If the waviness of a steel sheet is above defined limits, the steel user does not generally accept the annealed and galvanised product for high added value application because it can cause poor quality and downgrading in the further processing steps and notably after painting. As a consequence,...
