Effect of Precipitates on Surface Cracks in Continuous Casting of Steel
Details In recent years, the required properties of steel products are getting higher and higher, and the steel composition contains more alloy elements. Also, steelmakers are facing pressure to change their ironmaking & steelmaking processes to reduce CO2 emissions. In these environmental changes, maintaining and further improving the quality of casts [...]
Hybrid modelling of the continuous casting of steel
Details To prevent surface defects and enhance product quality, controlled cooling is essential. Ensuring the surface temperature remains above the "Leidenfrost-Temperature" is critical to form a stable vapor layer on the slab surface in order to maintain a consistent heat dissipation rate. This condition is influenced by several factors, including surface [...]
On the potential of endless strip production routes for the processing of advanced high strength steels from lower quality obsolete scrap
Details The ongoing transformation of the steel industry towards environmentally friendly steel production represents a major challenge. New technologies aim to reduce energy consumption and direct CO2 emissions by changing selected processes of conventional steel production routes. Thin Slab Casting and Rolling technologies, such as the Arvedi Endless Strip Production (Arvedi [...]
Hybrid process modeling of secondary steelmaking
Details As part of global decarbonization efforts, the transition to more sustainable steel production presents a significant challenge. A crucial step in this process will be the further optimization of secondary metallurgy, which is responsible for refining steel before continuous casting. This process plays a central role in modern steel production [...]
Impact of second phase precipitation and solute drag effects on austenite grain growth
Details In steelmaking processes like continuous casting, controlling austenite grain size is critical to achieving high manufacturing quality standards. Therefore, proper grain growth adjustment reduces the risk of strand embrittlement and surface cracks while significantly influencing the properties of austenite decomposition products such as ferrite, martensite, and bainite. This PhD thesis [...]
