Coordinator: José Carlos D’Abreu - PUC-RJ

Scope: Some alternative technologies for producing primary iron have been proposed in the past few years. Among them, it is highlighted the self-reduction, which uses as raw materials agglomerates for cold cure and self-reducing mixes. Brazil has held an avant-garde position in self-reduction, concerning both the generation of knowledge and the corporate initiatives for its application, as shown in the 1st Seminar held in the 58th ABM Congress. Considering these facts, the next Seminar will aim at presenting the evolution of knowledge related to the technologies that currently use self-reduction, providing an environment for debates on contributions that shall deal with preparation techniques, resistance and the nature of agglomerate connections and self-reducing mixtures, as well as the thermodynamical, kinetic and fluid dynamical aspects of processes, their physical and mathematical modeling and the environmental impacts related to this promising and emerging steel industry technology.

Coordinator: Geraldo Iran S. L. Cardoso - CST

Scope: Disclosure of industrial results, academic and fundamental studies, R&D projects, mathematical modeling, emulation of processes and physical metallurgy, related to mechanical forming of metals and their alloys (steel and nonferrous alloys). The following processes related to manufacture of parts, flat/non-flat and long products are included: rolling, forging, drawing, stamping and extrusion.

Recovery and Treatment of Rejects

Coordinator: Luis Cláudio P. Oliveira - MULTISERV

Scope: The 21st century started with the unequivocal break of the 20th century’s productive paradigm. Any discussion about the implementation or modernization of productive processes give privilege to the environmental preservation and has as starting point the adoption of cleaner production mechanisms. These mechanisms are intended to increase the efficiency in the use of raw materials, water and energy and foresee the non-generation, minimization or recycling of industrial rejects. However, in great part of the industrial processes, the generation of rejects is inevitable and its minimization is limited. In these cases, the implementation of efficient ways for recovery and treatment is imperative. Facing this scenario, this topic has as scope the discussion on the best operational practices adopted by the industry to recycle their rejects, as well as the technological trends in the segment. Environmental and economical aspects, both on new technologies and the ones already operating, will also be approached and debated.

Welding

Coordinator: Alexandre Queiroz Bracarense - UFMG

Scope: Welding is currently one of the most important areas in the manufacture of metallic components. Generally, or even specifically, several thermal, physical, chemical, metallurgical and mechanical phenomena are related to welding or with other phenomena that happen during the process. Due to the great range resulting from this relation, new welding processes, new concepts on metallurgy welding and new concepts of welding physics, related not only to the process, but also to the signals generated by it, have arisen or are starting to be used as a reference in the manufacture of metallic components, where new materials have been necessary. Thus, projects have appeared where metals that have previously never been imagined as capable of being welded, are being connected, metals with very high outflow stresses and special applications in several industry areas have been connected. Processes that not so long ago were prohibitive are being used, and the use of mechanical systems and robots have made welding increasingly indispensable.

Scope: The mineral technology approaches all studies directly involved in obtaining products adequate for their insertion as raw materials in metallurgic and chemical processes. It is an acknowledged area, characterized by its multidisciplinary nature, including processes that start with the identification of mineral resources to the production of enriched or, in some cases, virtually pure products. In Brazil, the mineral technology has been characterized mainly by actions and development of research in mining processing on its widest meaning, encompassing unit operations for preparation of raw materials, concentration (separation) of minerals and obtention of pre-products through hydrometallurgic, pyrometallurgic routes, among others. There are several centers of excellence in research and development in Brazil and the area can contribute considerably in terms of number of high-quality technical projects for the annual congress. Among the highlight areas, we should mention iron ore, copper ore, industrial ores (mainly kaolin and fertilizers) and gold ores.
