Course:MTRL467 Finger Cooling Heat Transfer

From UBC Wiki


General Information

This is a design project in course MTRL467 in the spring term of year 2020.

The proposed project title is "Design of a laboratory system to characterize heat transfer of the “finger” cooling configuration in permanent die casting".

Expectations

  • Students are expected to drive the process and act as consultants and the supervisors as customers
  • All the data related to die design and process parameters should be kept in confidence

Project Information

Background

The casting industry has been moving toward adopting knowledge- and database-driven design approaches from the traditional experience-based design methodology. For example, utilizing process simulation and optimization tools to achieve improved/optimized die design and process operation. These new approaches expose the need to quantitatively characterize the key process phenomena that occur during the casting process.

Cooling is one of the most important process parameters to control the casting process, since it is strongly related to the defect control, production rate and microstructure of the castings. Finger cooling with water is a commonly used cooling configuration in die casting processes for the production of aluminum automotive parts. Finger cooling provides localized and efficient cooling to extract heat from the casting die for the control of solidification. In this project, a lab apparatus will be designed and manufactured to quantify the heat transfer of the finger cooling configuration, which will provide valuable data for the industrial sponsor to aid in their die and process design activities.  

Project Objective

Design a laboratory system to quantitatively characterize the heat transfer of the finger cooling configuration used in die casting processes

Design tasks

  • Design a system to characterize the heat transfer of the finger cooling configuration.
    • H13 tool steel block and finger cooling insert (will be provided)
    • Heating system *
    • Data acquisition system (temperature) *

* Note: students may design the sub-systems based on existing work in the Advanced Metal Processing group

  • Purchase or work with the department machine shop to manufacture the necessary parts
  • Assemble the system and conduct tests to make sure it meets the design requirements
  • Conduct a set of experiments to collect data if time permits
  • Generate a technical report to deliver your engineering design
