industry overview
Industry Overview
  • U.S. Metalcasters consume over $1 billion in energy (328 trillion Btu) per year
  • Over 2,700 metalcasters in the U.S.
  • Total industry employs about 225,000 people
  • Small business industry - 94% of metalcasters employ less than 250 people
government industry r d partnership in metal casting
Government-Industry R&D Partnership in Metal Casting
  • Department of Energy Role
    • Improve energy efficiency in U.S. industry
    • Improve environmental performance
    • Foster R&D collaboration within industry and academia
    • emphasizing university-based R&D
  • Industry Role – through the Cast Metals Coalition (AFS, NADCA, SFSA)
    • Promote R&D needed by this small business industry
    • Provide leadership to and direct participation from industry
    • Transfer developed technologies to industry
program strategy vision technology roadmap
Program Strategy:Vision & Technology Roadmap

a new vision
A New Vision
  • Communicate its essential value to the U.S economy,
  • Improve casting design methods to open new markets and applications,
  • Improve the understanding and control of metalcasting processes,
  • Improve alloy and geometry performance,
  • Attract employees and students to the industry
  • A new Vision was completed in 2002 and a new Roadmap is near completion
  • Available at www.oit.doe.gov/metalcast
performance goals
Performance Goals
  • By 2020, energy use in casting will be reduced by 20% compared to 1998 energy requirements
  • Non-recycled solid waste and toxic chemical releases will be reduced by 25%
achievements
Achievements
  • Broad Participation and Outreach
    • Hundreds of organizations from across the U.S. have participated in cost-shared metalcasting research including small-, medium-, and large businesses, universities, laboratories, and federal agencies.
  • Partnership with Leveraged R&D Resources
    • 100 million dollars have been invested in metalcasting research, including investment from industry and the federal government.
  • Efficient Technology Transfer
    • Multiple R&D consortia have been fostered, resulting in broad information sharing and technology transfer.
  • Future Casting Workforce
    • University-based research has trained hundreds of students, the majority of whom have gone on to careers in metalcasting.
  • Enhanced Engineering Standards/Metallurgical Curriculum
    • Research results are being incorporated into the curriculum of U.S. colleges and universities, in some cases updating guidelines and instructional materials for the first time in decades.
selected research highlights
Selected Research Highlights
  • Advanced Lost Foam (Univ. of Alabama)
  • New design rules and unconventional approach for yield improvements in steel

(Univ. of Iowa)

  • Rapid Solidification Prototype Tooling (Colorado State Univ.)
  • Performance Data to Increase Reuse of Spent Foundry Sand (Penn State Univ.)
slide9

Advanced Lost Foam

  • Allows highly complex parts to be cast in one piece
  • Saves energy through reduced machining and assembly operations
  • No additives required in conditioning sand thereby making sand reusable
  • Saves energy by eliminating the core and through higher yield (less metal must be melted)
  • Clean Process / Higher Yield
studies in progress
Studies in Progress
  • Metal Casting “Energy Footprints” Study

(planned completion date: 12/2003)

  • Theoretical/Practical Energy Use in Metal Casting Operations

(planned completion date: 12/2003)

metal casting energy footprints study
Metal Casting “Energy Footprints” Study

Purpose:

  • Determine the energy use per unit of output for the various segments of the industry

Methodology:

  • Individual assessments of 15 “typical” metal casting facilities.
  • Utilization of Industrial Assessment Center Database
  • State metal casting energy studies
  • Metal casting literature searches
theoretical practical energy use in metal casting operations
Theoretical/Practical Energy Use in Metal Casting Operations

Purpose:

  • Evaluate theoretical and practical potential for reducing energy requirements to produce 1 ton of molten metal in metal casting operations

Methodology:

  • Conduct literature search to identify information and data on metal casting energy consumption and energy reduction
  • Compile and analyze data to evaluate the theoretical minimum, best practice minimum, and practical minimum energy requirements
  • Evaluate the potential for application of Combined Heat and Power techniques in the metal casting industry
  • Explore feasibility of a standard test to measure energy use
