Abstract
This 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.
