Title: Hasse Fredriksson: Innovator in Continuous Casting Technology
Introduction
Hasse Fredriksson is a notable inventor based in Stockholm, Sweden. He has made significant contributions to the field of continuous casting technology, particularly in methods that prevent segregation during the casting process. With a total of 2 patents, his work has had a considerable impact on the manufacturing of metals and alloys.
Latest Patents
Fredriksson's latest patents include innovative methods aimed at improving the continuous casting process. The first patent describes a method of preventing the formation of segregations during continuous casting by deforming the continuous strand plastically during solidification. This method physically reduces the cross-sectional area of the strand, corresponding to the solidification and cooling shrinkage of the material. The reduction typically ranges from 2-6% and can be achieved using apparatus with pairs of strand reducing rolls or jets along the strand. This approach effectively avoids the upward or downward transport of melt in the solidifying strand.
The second patent focuses on a similar method for continuous casting of steels and metal alloys. It emphasizes the importance of reducing the cross-sectional area of the strand to prevent segregation, following the solidification shrinkage of the metal. Like the first patent, this method also utilizes apparatus with pairs of strand reducing rolls or jets to achieve the desired reduction.
