dc.description.abstractThis paper explores the results of an experimental study that was intended to determine the thermal characteristics of an oil-fired crucible furnace using clay and alumina bricks. For the study, a refractory with 0.03118m3 combustion chamber capacity was used. The bricks analysis were carried out under transient condition that would be appropriate for laboratory and workshop with a capacity to reach 950oC within 20 minutes for aluminum and nonferrous scrap re-melting. The performance of the furnace was evaluated, and the results showed that the furnace can operate at a heating rate of 49.44°C/min, with a 29.70% efficiency determined, and which was within the efficiency range of conventional furnace. The heat transfer coefficient of 4.48W/m2K was obtained. Alumina bricks used in lining the furnace was attributable to its higher refractoriness. It was found that a better thermal shock was proved than clay bricks from the Comparative analysis simulation using commercial software ANSYS 14.0 aimed towards improving service life and efficiency.en_US
