| Abstract Scope |
Increasing residual element content in steel scrap streams occur during the recycling of steels through electric arc furnace processes, resulting in changes in continuous casting, thermomechanical deformation, material properties, and component performance. Current specifications generally have relatively strict Cu limits, for example, that might preclude recycling of certain scrap streams, or require blast furnace iron to dilute residual content. Here we discuss work to define steel compositions and associated processing windows to expand copper residual tolerance with known impacts on final properties and performance. Here we present assessments of available US scrap supply streams, melting and continuous casting characteristics, effects on thermomechanical processing, impacts on mechanical properties and weldability, along with a scrap optimization model including cost factors. |
