In this paper, Phil Geers, Senior Market Manager-Molten Metals, presents the effects and analysis of thermal stresses on large induction furnace refractory linings using Finite Element Analysis (FEA) techniques.
Monolithic rammed, mortared brick, and segmented brick construction were all compared and analyzed to determine where and why stresses are formed, and how the stresses can be minimized. The input conditions of the analysis were kept identical for all three simulations, with the only variable being the lining construction.
