1 MONDAY, 22nd October 2018. Past work relied much on the trial and error approach to International Courses developing and optimizing mold uxes and was considered black magic due to the signi cant variability and intuitive approach used for developing powders. ROOM D But today's development of synthesized mold powders for higher quality and enhanced surface quality of advanced steel grades require a more fundamental approach based on scienti c principles and near commercial condition Materials Science and Engineering of Modern simulations of the developed powders.

2 Automotive Steels ROOM F. Dr. Wolfgang Bleck (RWTH Aachen University, Germany). Steel is by far the most signi cant metallic material group. It Recent Developments on EAF Technology and contains over 2500 steel grades and offers a wide variety of Operation property combinations to be applied to different uses. Many of these steel grades were recently modi ed or have been newly developed. Combined with new processing methods, they are an interesting and challenging eld for engineers. This course is an introduction to the fundamental laws of Dr.

3 -Eng. Thomas Etcherhof material development with a strong focus on steels for (RWTH Aachen University, Germany). automotive application: new advanced high strength sheet steels for car bodies, new hot rolled press hardening steels for crash relevant parts, new microalloyed and bainitic steels for gear components. The course introduces to an engineering approach of how to Steelmaking in the electric arc furnace accounts for about 25. develop steels and their processes, of how to achieve % of the worldwide steel production in 2017.

4 In the European desired properties, and of how to appropriately use the Union its share is about 39 % of the total steel production. material. The course begins by acquainting the participant Argentina reported a similar ratio of about 44 % for 2017. with the physical and chemical characteristics of the element EAF steelmaking therefore is a very important steel iron. Important alloying elements for steels are introduced by production route. If based on steel scrap, it also has the means of phase diagrams. The microstructure formation and typical advantages of recycling processes with regard to the technical signi cance and application of phase energy consumption and environmental impact in transformations are discussed.

5 The practical relevance of the comparison to primary steelmaking routes. The variability of introduced physical and chemical phenomena for steel the EAF process with regard to input materials, furnace development and application is explained with respect to the equipment and operation as well as produced products processing both of strip and of long products. The creates a challenging eld of work for engineers. requirement of various customers will be discussed; a focus This course will give an overview on the recent developments is laid on the automotive industry as one of the drivers for in EAF technology and operation.

6 It starts with a review of recently developed new products. EAF fundamentals: production routes, raw materials, furnace concepts etc. The main focus will lie on energy and resource ef ciency of the process as well as environmental aspects of ROOM E steel production in the EAF. Mass and energy balance of the EAF process as tools to determine ef ciencies are discussed. Parameters in uencing the overall ef ciency of the process like electrical ef ciency, heat transfer parameters, energy recovery and scrap preheating are Understanding Mold Powders, is It Black Magic?

7 Introduced. Measures to improve the resource ef ciency and to reduce the environmental impact of the process will be discussed including the use of biomass, the reuse of steelmaking residues, etc. The course will be completed by a review of developments in the area of process control and Dr. Il Sohn automation. This topic includes the use of robots at the EAF, the application of process models and through process (POSCO Professor, Yonsei University, control. The relevance of Industry in general at the EAF. Korea) steel plant will be highlighted.

8 Each part will be concluded by a questions and answers With greater consumer demands on quality, continuous section. The participant is invited to provide questions from casting mold uxes have become a topic of tremendous his speci c industrial experience, the answers will be interest in both academia and industry. Several essential developed by group discussions. roles of mold powders include absorption of non-metallic inclusions from steels, protection of steels from the atmospheric conditions, insulation and control of uniform heat transfer of the super-heated steel melt across the water- cooled copper mold, and lubrication between the partially solidi ed steel shell and copper mold.
