This furnace has a work zone of 500 mm diameter and 1.5 meter length and it can be operated up to a temperature of 1100 deg C. A Titanium-Zirconium-Molybdenum (TZM) alloy job carrier has been designed for a load carrying capacity of 400 kg for better utilization of the vertical space. Due to alloy’s outstanding combination of properties e.g. high electrical and thermal conductivity, low coefficient of thermal expansion and high rupture as well as creep strength; it is a preferred choice in a wide variety of high-temperature applications in spite of its higher cost. The structural design of the job carrier needs optimization in order to reduce its weight as well as its cost without compromising on design constraints. In this paper, a detailed design of job-carrier has been presented using plate theory and Euler beam theory. Subsequently, finite element analysis (FEA) in ANSYS TM Workbench is performed to ensure that resultant stresses and deformation are within acceptable limits. Additionally, a limit load analysis has been performed to determine the maximum load capacity and factor of safety. FEA results are then used for fatigue life and creep assessment. The job-carrier has been successfully installed inside RRCAT’s controlled atmosphere furnace and has been tested at full load. The effort has also le d to 70% reduction in the procurement cost with respect to commercially available products. © 2024 The Authors. Published by ELSEVIER B.V.
