7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

DRIpax™ is an integrated process optimization system for MIDREX DR Plants jointly developed by Primetals Technologies and MIDREX Technologies. This new system was installed for the first time at the MIDREX DR plant Module 2 of Qatar Steel and is now successfully in operation at this plant. The installation at Qatar Steel demonstrates the high prediction accuracy achieved with the new product...

The use of DRI can help steelmakers facing the more and more tough environmental policies and market competition of modern times. Even better results can be obtained by using high-carbon DRI, a pre-reduced material with minimum 3.5% Carbon content, most of which in iron carbide form. This upgraded quality is the result of specific direct reduction's operating conditions, that are peculiar to...

A constantly increasing focus is, nowadays, put on the CO2 and environmental impact of the steel industry, especially in EU and Japan. This can be seen as an unique opportunity for the steel producers to improve their reputation amongst the public community, too often loaded with unjustified prejudices. Even if the measures required to meet the ambitious target of EU to decrease CO2 footprint...

Understanding and managing the risks associated with the introduction of a new technology in the highly capital-intensive, large volume and low-margin iron and steel industry, is a key to effectively implementing a lasting change. Hatch has developed a robust methodology for process technology selection for the iron and steel industry to address the risks. The methodology is based on a...

Effect of heating rate on the properties of two non-coking coals in thermal regime of tunnel kiln direct reduction of iron (TKDRI) process has been investigated. The low rate heating condition of raw materials in refractory crucibles of tunnel kiln was simulated in a vertical TGA for two different non-coking coals. The heating rates of 1.5, 3 and 7 oC/min from room temperature to 1100oC were...
