| Abstract Scope |
Copper smelting furnaces are typically lined with magnesia-chromite refractories. This paper evaluates the common refractory wear mechanisms of infiltration, spalling and chemical attack as observed in the copper anode furnace. All these wear parameters lead to severe degeneration of the brick microstructure and to a decreased lining life. Additionally, the influence of infiltration on the thermal conductivity and temperature field on a simplified furnace lining was investigated by means of numerical simulation. A steady state heat transfer finite element analysis was conducted using a theoretical model of a cross-section of the furnace. Two cases with different material properties were considered. The first case considered virgin lining and the second a lining with deep slag infiltrations. Accordingly, a detailed investigation and understanding of the wear mechanisms through “post mortem studies” in conjunction with numerical simulations is an important prerequisite for the refractory producer. |
