Oxidation processes are almost unavoidable in the production and further processing of steel. Therefore, a better understanding of its mechanisms is crucial. Simulating selected process steps, like casting, heat treatment or hot rolling, by simultaneous-thermal-analysis (STA-DTA/TG measurements) improve the understanding of the influence of process parameters and steel composition on the formation of surface [...]
High Temperature Laser Scanning Confocal Microscopy is used to observe surfaces of samples at elevated temperatures up to 1750°C. The set up consists of a He-Ne Laser as a light source and an infrared heating chamber. The He-Ne laser in combination with a pinhole blocks out thermal radiation of the sample enabling the observation [...]
The primary focus of this research group are divers questions concerning the cleanness of steels using different experimental and analytical methods as well as thermodynamic and kinetic calculations. The cleanness of steels is an essential quality criterion for a wide variety of special steel applications. Non-metallic inclusions can initiate cracks or other material defects [...]
Development of novel process strategies for thin slab casting and direct rolling (TSDR) The production capacity of installed TSDR plants worldwide amounts today to significantly more than 100 Mio. tons/a. Among these technologies, the endless strip production routes show the highest potential with respect to unique homogeneity in the mechanical properties along the entire strip [...]
To satisfy increasing demands in product quality and process efficiency a comprehensive understanding of the continuous casting process is necessary. Solidification models can help to increase the knowledge about the influence of process parameters on solidification behavior during the casting of steel. The Chair of Ferrous Metallurgy has developed models in one and two [...]
The development of new alloying concepts, the modification of production routes due to the de-carbonization of steelmaking and last but not least, increasing quality demands will additionally stimulate research activities on high-temperature oxidation.During steel production and processing, the product surface is exposed to temperatures up to 1250 °C and a wide variation of oxidizing atmospheres.
