Enhancing High Alloy Steel Quality Through Improved Recycling and Separation Techniques

High alloy steel often suffers from contamination, leading to off-chemistry heats that compromise quality. ArcelorMittal faces significant challenges with contaminated steel scraps, which affect the integrity of their products. We recommend the implementation of a new separation technique, starting with proper labeling and assembly at car manufacturers, and developing a standardized testing process for incoming scrap. By utilizing spectrometers and designating recycling areas, we can ensure better quality control and reduce contamination, safeguarding the chemical makeup of molten iron.

  1. Project Strategies Natalie Hoopes Erica Kontson Elizabeth McClure

  2. Defining the Problem • High alloy steel is not being separated properly • There are contaminates in the steel, which can cause off-chemistry heats • ArcelorMittal has to deal with these contaminated steel scraps that come into their company and it takes away from the quality of the steel • Determine the chemical composition of molten iron

  3. What we need to do • A new separation technique needs to be implemented so there will not be off-chemistry heats -Might be carried out properly through each stage of recycling the steel -Deciding who is responsible for the separation (other than ArcelorMittal) -Encourage de-coating techniques to get rid of contamination -Test the chemical makeup of the incoming scrap -

  4. Solution Strategies • Start at the car companies • Assemble the car with specific alloys that are marked properly to show the chemical composition • Create a sample testing • Disassemble the car, separate different types of steel before shredding into smaller components • Create areas especially designed for recycling • Transfer separated steels to the next step of the reusing process

  5. Solution Strategies cont. • At the recycling location, assign the responsibility of further testing and separating of the steel • Spectrometers to measure the chemical composition • After this, separated steels will be sent to ArcelorMittal • Alternative: have ArcelorMittal implement the recycling and separation process • Spend money to gain money (incentive)
