She is making Swedish steel even better

Published Dec 28, 2010

The high quality of Swedish steel is widely known around the world. The steel will now become even better, thanks to KTH researcher Jessica Elfsberg.

The research that Jessica Elfsberg is engaged in concerns the steel produced through continuous casting. It has been shown that some defects occur when continuous casting is carried out because the mould is shaken in a specific pattern and at a certain speed.

”I have carried out a survey, of among other things, the casting powder which is used and the surface tension that arises during the continuous casting of steel. My research is a contribution to make steel better,” says Jessica Elfsberg, who conducts research in the field of materials processing engineering at KTH.

She adds that the research she conducts also helps us to understand the incredibly complex process of steel production. At the same time, Sweden is far ahead in terms of steel, and Swedish steel, according to Jessica Elfsberg, is very competitive on the international market.

Her research about steel affects a variety of industries where continuous casting is commonly used for steel which is used in different contexts.

”Continuous casting is done on all kinds of steel, such as body panels for cars, special steels for recovery boilers that operate in a hot and corrosive environment, and the spring steel used for cushioning, for example in the chemical industry,” says Jessica Elfsberg.

It is the trade association Jernkontoret that has funded the research, and according to Jessica Elfsberg, Jernkontoret has facilitated collaboration between the steel companies and research in Sweden which strengthens Sweden’s steel exports.
