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 objective of this research project was to improve steel metallurgy and quality by optimisation of the ladle stirring process. Throughout the project, the interactions between solid, liquid and gaseous phases involved in ladle stirring were examined. • Melting of alloying materials was...

A new deadman (DM) porosity and position criterion was developed using bottom temperature and tapping data. This was established online at industrial plants. The ultrasound technique AU-E seems promising to assist with conventional wear determination. Copper was successfully established for...

The main aim of the study is the development of tools able to predict hydrogen content in steel and to assess the best practices to keep it below the critical threshold. A survey of current hydrogen detection methods both for liquid and solid steel have been carried out and the most reliable...

The MAC D project has shown a realistic potential to replace today's carburizing route in the manufacturing of a helical gear with an induction hardening route. The transition includes evaluation and choice of a new suitable steel and as delivered microstructure from the forging, data of...

AVENTO was a 3-year research project that was aimed at the development of advanced tools for improved control of ventilation networks in underground coal mines; for i) improving the safety at working areas through a better control of methane emissions and climatic conditions, and ii) optimizing...

Modern reheating furnace control systems currently use limited measurements of the furnace temperature coupled with simple empirical mathematical models to predict and following regulate stock temperatures. However existing measurement data capture only a small amount of information about the...

The aim of this pilot research was to develop and operate a better control of initial solidification at meniscus level to enhance surface quality of as-cast products. Innovative fibre optical temperature measuring technique was applied into a 185 mm × 185 mm billet mould of a six strand caster....

Nine spinnable alloys were defined for initial trials. After the first galvanizing trial on rods two alloys were identified for further testing on bolts with spinning, namely Zn20Al4Mg and Zn20Al. Although the large number of tests did not yield adequate coating quality for bolts, correlations...

The main objective of the BATIMASS project was to address how the energy balance in relatively lightweight steel buildings can be improved by building in 'active thermal mass' (ATM) into the building fabric. This was achieved through concept design, dynamic thermal modelling and testing of a...
