Casting peritectic steel grades continuously is a complex challenge. The formation of the initial solid shell inside the mold is crucial to producing high-quality billets. A key factor in this process is choosing the right mold powder to optimize heat transfer between the billet and the mold. At Ovako's steel plant in Smedjebacken, this master thesis gives you the opportunity to investigate how different mold powder compositions affect the quality of continuously cast billets of peritectic steel grades.
A thesis for those who want to understand how casting conditions impact steel quality
The continuous casting process for peritectic steels is sensitive to the interaction between the mold powder and the billet surface. The powder affects heat transfer, lubrication, and the formation of the solid shell - all of which determine billet integrity and defect levels. Your work will involve analyzing different powder compositions and evaluating their effect on billet quality, helping Ovako improve casting outcomes and reduce defects in the rolled product.
In this master thesis, you'll collaborate closely with Ovako's experts at the steelworks. You'll apply metallurgical testing methods including macro-etching and sulfur print examinations, along with SEM (scanning electron microscopy) to characterize the microstructure and assess the effects of mold powder on billets.
The outcome? Valuable insights and a clear recommendation on optimal mold powder composition for casting peritectic steel grades - contributing directly to enhanced product quality and process reliability.
Why choose Ovako?
This thesis is for the curious and driven student who wants to gain hands-on experience in materials science and process optimization within the steel industry. You'll be based in Smedjebacken, Sweden, working alongside a skilled team dedicated to innovation and continuous improvement.
At Ovako, we are committed to doing what's right - for our customers, our materials, and our future. If you want to contribute to making steel production smarter and more sustainable, we'd love to hear from you.
