| Abstract Scope |
Manufacturing steel strips and sheets from recycled end-of-life steel is limited by the presence of Cu because it causes surface cracking during hot rolling, phenomenon called surface hot shortness. We present a novel strip peeling process to suppress hot shortness and produce high-quality sheets from high Cu-containing steel compositions. The primary advantage is that, unlike hot rolling, strip peeling – process that exploits single-step deformation to produce thin strip directly from a cylindrical feedstock – does not involve bulk heating to elevated temperatures, thus eliminating hot shortness. Results pertaining to the effect of Cu (0.1-2 wt.%) on strip quality, microstructure, and mechanical properties will be presented along with a brief discussion of a modeling framework to understand the maximum limits on Cu in peeling. The technology has potential to expand the range of applications in which recycled steel can replace primary steel, while also reducing the energy and carbon footprint. |
