Different phenomena leading to the degradation of the refractory lining at the bellyband of aluminum holding and melting furnaces are described. The effect of alloy composition, fluxing agent and surrounding atmosphere, on the corrosion of aluminosilicate refractories in such applications has been studied. A laboratory test that simulates the conditions at the bellyband in the above furnaces was developed. Results suggest that sidewall build-up originates from corundum formation at the surface of the molten metal, which then grows inside the refractory above the metal line.
