  2. Introduction • We recognize the need to design a new process to identify, separate and store the high alloyed scrap from the rest of the scrap from the automotive junk yard.

  3. Table of Contents • Introduction • Background • Specifications • Weighted Objective Tree • Brainstorming • Decision Matrix • Flow Chart • Sustainability

  4. Steel Recycling • Steel is North America's most recycled material • Use of steel scrap to make new steel conserves energy, reduces emissions and conserves natural resources • Each year, steel industry recycles more than 18 million tons of steel from cars • Use of AHSS reduces a vehicle’s structural weight by as much as 25% and can cut CO2 emissions by up to 15% more than any other automotive material. • Automobiles maintain a recycling rate of nearly 100 percent1

  5. Background • Steel  composition of different metals  the strongest alloy  “cradle to grave” --> “cradle to cradle” • ArcelorMittal delivered automotive scrap  stays separate from other scraps such as ore  lollipop sampling  spectrometer tests the makeup of scrap metal (inefficient) • Our task:  new solution to effectively identify, transport and store the high alloyed steel  ensure there is no off chemistry when making recycled steel  decrease the cost of production while increasing revenue (if possible)

  6. Background cont’d • Recycling steel  separate (AHSS) from scrap  AHSS burned in basic oxygen furnace  metal slag drains out  other gases leave furnace  alloy compounds added to AHSS in airtight vacuum to create necessary percentage of metals to create LCAK steel.

  7. Specifications Avoid off-chemistry -system must maximize the amount of highest alloyed steel that can be added to a heat of standard LCAK steel without off-chemistry - keep AHSS separate throughout whole process - Use reliable composition evaluation techniques Cheap - Not cause a dramatically increased cost for ArcelorMittal - Avoid outsourcing and paying other companies Separates AHSS - Separate and identify the AHSS from the automobile scraps - Keep scrap composition in specified range (C 0.17% Cr 0.2% Cb 0.02% Mn1.5% Al 1.2%)

  8. Specifications Cont’d Safe/reliable - Process works effectively every time - Does not cause increased danger risks Accurate -Proper composition measurement techniques are used, Spectrometer - The average results of multiple tests are used - Proper sample sizes of metal are used (small strips) Time efficient - Avoid taking lollipop samples of every small piece of metal, but remain accurate -Short, fast transportation

  9. Morphological CHart

  10. Decision Matrix A: -Car Co. Labels Parts by comp. -Junkyard Separates by label-A.M. Re-Measures and Uses B: -Junkyard Separates Parts-Couple samples from small piles analyzed by another Co. for comp. - Crates with parts sent to A.M. labeled by comp. C: -Junkyard separates parts -Small piles melted into large slabs analyzed by another Co. for comp. -Slabs sent to A.M. labeled by comp.

  11. Cost Analysis

  12. Sustainability • Environmental - Our design does not dramatically alter the steel making process, which is good for current research and development programs -The North American steel industry has been actively investing in research into new processes for making steel that reduce or eliminate CO2 emissions2 • Economic -Cost will increase slightly for car companies to label the compositions and for junkyards to separate individual parts - ArcelorMittal does not have to spend time and money to analyze the incoming parts - Overall, the new steel will be made more accurately and with more AHSS; the cost of the final products will increase—ArcelorMittal makes more profit

  13. Sustainability Cont’d • Social - Design allows job opportunities in the car companies and junkyard companies - Having more AHSS, along with the accurate steel-making process, allows for safer construction - Labeling regulations create order and consistency in the industry
