Design and Thermal Analysis of Crucible Furnace for Non – ferrous Metal

Abstract

The advancement of any nation technologically has been influenced and elevated by the extent to which it can usefully harness and convert its mineral resources. The productions of metal in foundries and in all human lives have also become a general practice. Different melting techniques are in practice with different energy sources, hence the need to analyzing the heat flow in the crucible furnace during melting operation of the scraps in the crucible pot of the furnace. This paper focuses on the analysis of transient and steady state of heat flow across the entire area of the inside furnace by employing Granter CesEdu pack, 2011 for materials selection, Creo element for geometry development of the furnace and Ansys 14.0 for the thermal analysis. From the analysis the maximum total heat flux is 1275200w/m² which is found inside the region of the furnace and a minimum of 3.9833e^-12 W/m² at cold outer region of the furnace, also the positive heat flux of 835740w/m² inside the system and heat loss to the surrounding of 761420w/m²were obtained at point of heat supply channel.
