Conquering Aluminum Furnace Corundum Effective Controls
Jun 18 2019 · Root Causes of Corundum Growth Corundum growth in a refractory lining of an aluminum furnace occurs due to a reaction between the alumina-silicate refractory and molten aluminum. Corundum formation can occur both externally and internally in the refractory lining. There are four identifiable root causes that promote corundum growth
