EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

voestalpine – a steel-based technology and capital goods group and a world leader in the development, manufacturing and processing of sophisticated metal products - is focused on technology-intensive sectors, such as the automotive, railway, aviation, and energy industries that are drivers for innovation. Combining know how on metals and in processing together with an open innovation approach...

After a short decision making process voestalpine Stahl Linz decided in June 2013 about their largest foreign investment project for the installation of a 2.0 MTPY Midrex HBI plant in Corpus Christi, Texas/USA. A consortium of Primetals USA LLC and Midrex Technologies was awarded for the supply of Equipment, Engineering and Technical Services of the Direct Reduction plant as green-field...

Outotec is a pioneer in rotary kiln direct reduction with coal offering the well-proven SL/RN and the more recent SL/RN-Xtra technologies. The SL/RN-Xtra technology uses hot offgas from the rotary kiln to pre-harden green pellets on a travelling grate, before they are fed to the rotary kiln. This not only increases energy efficiency of the process, but also the production rate of the standard...

Rising energy demand and steadily decreasing quality of raw materials due to the global resource depletion are great challenges to the steel production today. The FINEX® Process has been developed jointly by POSCO, Korea and PRIMETALS Technologies Austria, to provide the iron making sector with the capability to lower hot metal production costs, environmental pollutions and to increase the...

Coke oven gas (COG), as a kind of high heat value source, was projected to be injected into free board of the COREX melter gasifier. In this paper, a static model had been created based on mass and heat balances. The model was capable of calculating the temperature of free board, the quantity of COG injected and top gas. The results showed that the COG injection into free board can adjust its...

An integrated process optimization system for MIDREX DR Plants has jointly been developed by Primetals Technologies and MIDREX Technologies. This system was installed for the first time at the MIDREX DR plant Module 2 of Qatar Steel. The new product quality prediction models achieve high prediction accuracy – hours before the measured data are available. This supports quick decision-making to...

Module-E, one of the largest MIDREX direct reduction plant in the world with more than 2.5 MT iron oxide consumption. The oxides used in its Shaft Furnace (SF) is in pellet shape of size 6 to 18 mm diameters. However, during palletization process at suppliers’ locations, and transportation afterward, undersized pellets are generated. In the plant, undersized materials are screened off from...
