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...

The project objective was to develop a through-process control strategy for a reliable, simultaneous achievement of low steel carbon and nitrogen levels within the electric steelmaking route under minimum energy and material costs with optimal productivity. Detailed investigations on the effect...

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...

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 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...

The current blast furnaces are efficient and highly optimised and the scope for further lowering the carbon usage (and thus CO2 emissions) in these furnaces is approaching its limits. A possible breakthrough solution is to recycle the remaining CO and H2 in blast furnace top gas back into the...

The technical objective of this project was to investigate the interaction between deoxidised steel melts and metallurgical slags, ladle lining and ladle glaze during ladle treatment. Low carbon micro-alloyed steels and tool and stainless steels were chosen for investigation. These aspects were...

This study is a collaborative work between VDEh-Betriebsforschungsinstitut GmbH (BFI) and ArcelorMittal Bremen GmbH (AMB). It was the aim of the project to compare different types of suction hoods (with and without swirl), to elaborate which are most effective for the given case of fume...

The Active Tundish Metallurgy project aimed at improved, better guaranteed steel cleanness by applying tailored tundish slag with high capacity to efficiently absorb macro- and micro-inclusions from different steels. Thermodynamic calculations showed that industrial partners' slags used in their...
