Minimizing crack formation in continuous casting

Published: 1 December 2020

A better understanding of how harmful cracks occur during continuous casting of steel can have positive effects for SSAB with several steel companies in the world. It can increase productivity, which means better economy, less energy consumption and greater environmental benefits. It appears from a new doctoral dissertation at Luleå University of Technology.

– The information I have developed in my research is the key to avoiding losses in production and defects in the cast end product. This in turn benefits the entire global steel industry in terms of economy, energy and environment, says Rosa Maria Pineda Huitron, doctor in engineering materials at Luleå University of Technology

In her research, she has focused on studies of various phenomena when steel blanks, so-called slabs, are cooled during continuous casting of steel. She has studied how certain parameters in the cooling process affect the risk of cracking and thus been able to identify how the material behaves.

– In four scientific articles that explain and identify some of the risks of cracking, I have produced information that is central to reducing productivity losses and defects in the finished, directly cast product, she says.

With her research, she has firstly increased the knowledge about oxidation in connection with continuous casting, how to reduce the cracking sensitivity of steel during the cooling itself and how to model some of the parameters in the casting process. Second, her research has added strategies to reduce the risk of cracking in connection with steel continuous casting.
