[EE2] Clean Manufacturing of Steel and Alloys: Clean Manufacturing of Steel and Alloys
- Min-Kyu Paek (Research Institute of Industrial Science & Technology, Korea)
Description
The greenhouse effect by carbon footprint has warmed Earth’s surface and caused many problems such as climate changes, elimination of species, agricultural productivity, water shortage, etc. Traditionally, CO2 emission was the inevitable consequence of using cokes or coal to produce steels and alloys from ores. In order to minimize the environmental impact, steel and alloy producers can contribute to lower CO2 generation during their processes. However, transitioning and alternative ways of manufacturing have to be investigated to establish zero-emission processes. In this session, the environmentally friendly production of metals and its applications will be discussed. The proposed topics are as follows:
- Reduction of raw materials to synthesize alloys using H2 or natural gases
- Production of green hydrogen and its application for metallurgy
- Minimizing CO2 emission with carbon capture and storage technologies
- Any other alternative reduction agents such as biofuel and industrial waste
- Additive manufacturing (Metal 3D printing)
- Alloy melting technology by laser, microwave, electric energy, etc
Metallurgical slags and oxidic side streams from steel and non-ferrous metals production are potential sources for recovering valuable metals. Due to large volumes of slags and side streams, it is of economic interest to develop methods to recover the valuable metals from these streams. In copper and nickel smelting, valuable metals such as Cu, Ni and Co, may be either entrained as metal alloy...
The 1.5 °C target is the goal of the Paris Agreement, which calls for countries to take concerted climate action to reduce greenhouse gas emissions in order to limit global warming. For the global warming to stay below 1.5 °C, the world needs to transform to zero emissions by 2050. Reaching this global climate target requires significant decrease in CO2 emissions by increasing the use of...
Non-metallic inclusions play an important role in determining the quality of steel products; Thus there have been various researches done in order to study such inclusions. Adequate knowledge about the behavior of nonmetallic inclusions in molten steel and during the solidification stage bas been discovered. However, the effect of non-metallic inclusions on the quality of steel products is...
In the domestic metal powder manufacturing industry, there is an ongoing effort to promote the transition to the next-generation smart factory by the digitization of tacit knowledge using artificial intelligence (AI). This successful initiative enables one company to become global competitiveness in high-efficiency metal powder production. Although the previous AI-based works in our laboratory...
