Abstract
The Nodal Wear Model was developed to systematize the analysis of corrosion phenomena on refractory and ceramic materials that come in contact with corrosive fluids in furnace linings. The model is based on the determination of the thermal field in the furnace lining using a finite-element-method grid in which a second grid is defined to represent the surface of the lining that is attacked by the molten phases. Using a control equation for the wear-corrosion thermal-activated phenomena, a modification of the geometry is introduced and a new geometry is defined to restart the calculation.
