Presentation Title Energy Savings through Thermally-efficient Crucible Technology: Fundamentals, Process Modeling, and Applications
Author(s) Wenwu Shi, Brian Pinto
On-Site Speaker (Planned) Wenwu Shi
Abstract Scope Melting and holding molten metals within crucibles account for a large portion of total energy demand in the resource-intensive nonferrous foundry industry. Through the use of multivariate mathematical modeling aided by detailed material characterization, advancements in crucible technologies have been able to make a significant impact in the areas of cost-efficiency and carbon footprint. Key thermal properties such as conductivity and specific heat capacity were studied to understand their influence on crucible furnace energy consumption during melting and holding processes. Effects of conductivity on thermal stresses and longevity of crucibles were also evaluated. With this information, accurate theoretical models using finite element analysis (FEA) were developed to study total energy consumption and melting time. By applying these findings to recent crucible developments, considerable improvements in field performance were reported; documented as case studies in applications ranging from aluminum holding to zinc oxide production.
