| Abstract Scope |
High silicon steel Fe-6.5Si (wt.%) is a favorable candidate for high-speed motors and high-frequency transformers. Fe-6.5Si has higher resistivity (82 µΩ cm) than traditional 3.2% silicon steel (52 µΩ cm), leading to lower eddy current loss. However, increased silicon content also makes Fe-6.5Si too brittle to be processed using the conventional process, such as cold rolling. Rapid solidification by melt spinning is a viable route for ductile Fe-6.5%Si manufacturing. Unfortunately, lab-scale production of ductile Fe-6.5Si has a limitation in its width and scale and cannot meet industry demands for motor testing to quantify improvements. Viable processing routes to bridge the gap between lab and industrial pilot-scale production of Fe-6.5Si are in great demand. In this talk, we will discuss processing parameters, melt handling materials, and alloy additives for continuous 6.5%Si steel tape production that is at least 50 mm wide. |
