Comparative Analysis of Refractories for the Lining of a Non-Ferrous Metal Crucible Furnace
Journal Title: Scholars Journal of Engineering and Technology - Year 2016, Vol 4, Issue 9
Abstract
Abstract:This paper examined the effect of heat on refractories used for the lining of the wall of crucible furnace; the refractories are bricks, zirconia and alumina. Knowledge based software such as Creo-element/Pro5.0 and ANSYS workbench 14.0 were employed for the modeling and steady state thermal analysis of the furnace. A temperature of 350C was used as initial temperature of preheating and a temperature of 8000C as the pouring temperature. Maximum heat flux of bricks, zirconia and alumina were found to be 4.9967*10-8 W/m2, 6.5999*10-6 W/m2 and 6.6098*10-6 W/m2 respectively, and the maximum directional heat flux of bricks, zirconia and alumina were found to be 1.0019*10-8W/m2,1.2572*10-6 W/m2 and 1.34*10-6 W/m2 respectively. Comparatively, it was observed that, thermal loading was high in zirconia and low in alumina. Keywords:Furnace, Crucible, Non-Ferrous, Metal and Refractory
