design task
Design Task
  • Primary goal: (from project kick-off presentation)
    • Separate advanced high strength steel (AHSS) from scrap autos
    • Use mix of AHSS and low carbon aluminum-killed (LCAK) scrap to make LCAK heat
research
Research
  • Research required to familiarize the team with steel recycling
    • How scrap is processed
    • How materials are combined to make steel
    • How different alloys affect steel characteristics
    • Characteristics of the steel to be sorted (AHSS and LCAK)
brainstorming
Brainstorming
  • Analyzed several potential methods of sorting scrap
    • Magnetism, density, melting point, eddy currents
  • Research found that optical emissions spectrometry could be used to differentiate between the types of scrap
  • Chosen for being a proven, pre-existing technology
how it works
How it works?
  • Optical Emission Spectrometer
    • Heats up atoms in material
    • Different elements give off unique frequencies of light
    • Different frequencies used to determine material
steps in process
Steps in Process
  • Scrap steel sorted in Optical Emission

Spectrometer
