The Design and Benefits of a Thermally Stable Container

摘要

The paper addresses how the thermal and mechanical design of a container influences liner bore and container body temperatures, operating stress levels, billet skin inflow, and tooling life. To help better understand container performance, modeling is presented for various container designs and heating concepts. Based on the data, the paper describes how heating elements and thermocouple configurations, along with best design and operating practices can achieve thermal stabilization. This contributes to both improved mechanical and thermal container performance, leading to extended container life and reduced process scrap. By process of improved and controlled billet flow into the die, resulting from container thermal stability, extrusion surface defect issues and run out variations are reduced, as well as improved extrusion dimensional consistency. This drives optimization and increased productivity.
