The U.S. Department of Energy (DOE) is proposing to provide funding to Purdue University for the design and development of a new process for production of high-silicon electrical steel sheets. The project involves a first-stage process scaling and a second-stage scale-up of the primary process. Once the target scale is achieved, a new kinematic pilot production system would be designed/built to produce the steel sheets at the target scale.
The proposed project would develop a scaled hybrid cutting-extrusion process in order to produce a new class of electrical sheet steel from iron-silicon alloys of high silicon content. This class of steels would have superior magnetic and electrical properties that could enhance the efficiency and performance of electrical motors. Besides enabling production of the high-silicon content steel sheet that is very difficult to produce by current multi-stage sheet rolling processes, the cutting-extrusion would produce sheet from billet in a single step, be less energy-intensive than rolling, and would require much simpler infrastructure than current sheet forming processes.
