Item Design and Fabrication of Electric Muffle Furnace(Civil Engineering Department, University of Ilorin, 2018) Ahmed, Ismaila Idowu; Adebisi, Jeleel Adekunle; Busari, Yusuf O.; Ogunbiyi, I. B.; Gbadebo, A. O.; Adeko, A.; Omowumi, A.; Olanrewaju, S. O.; Abdulkareem, SulaimanThis work was aimed at the design and fabrication of heat treatment furnace, with automatic control system, using locally sourced materials. Computer- Aided Design (CAD) and Autodesk Inventor Professional were used for the structural design. And, consistent with materials selection procedures, mild steel was selected for the fabrication of casing, while other appropriate materials for the construction were selected based on service need using their relevant properties, cost considerations and ease of fabrication into the various component parts. The International Electric Equipment (IEE) regulation (BS 7671) was also followed in electrical and electronic components design to ensure compliance with the international standard. Performance evaluation of the muffle furnace showed a maximum attainable temperature of 920°C inside the enclosed heating chamber after a period of 15 minutes of continuous heating. This showed that, the furnace is suitable for all forms of heat treatment and melting of both ferrous and non-ferrous metals within the maximum attainable temperature. The maximum operating temperature of 650°C was therefore advised to ensure health and safety and extended operation life of the heating element.
