A growing number of EAFs are equipped with wall-mounted injectors and operate with the slag-door closed. In order to observe the scrap-melting process under these conditions, CRM has developed a camera-based technology to monitor the inside of the furnace during meltdown. The camera system is...

The main objectives of ERAMAC were to: - develop methods for the characterisation of organic emissions from coke-making and EAF steelmaking processes; - characterise air quality in the vicinity of steelworks; - identify priorities for emission control; - develop predictive emission monitoring...

The objective of the project was the development of techniques to improve the control of the energy input by natural gas burners and of the wall mounted oxygen and carbon injectors of the electric arc furnace (EAF). Process data acquisition and measurement systems for foamy slag detection were...

In the framework of the European RFCS project named ISA-PESR, an integrative software simulation tool focusing on numerical modelling of the protective gas electro-slag remelting (PESR) process has been built up. To achieve this goal several tasks were organised. First the collection of data...

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 research fund for coal and steel was established 2002 to support the competitiveness of the European Coal and Steel sectors by supporting research, pilot and demonstration projects. This brochure contains a small selection of running and closed projects which highlight some of the innovative...
