The environments and operating conditions within the spray chambers of steel continuous caster machines promote corrosion of susceptible components, particularly those made of carbon steel. Two major corrosion mechanisms observed in most casters are oxygen corrosion and acid corrosion. Acid corrosion may produce substantial damage at rapid rates. Evidence collected from field and laboratory investigations indicate a link between usage of certain types of mold powders and water alkalinity reduction. Laboratory procedures may be used to predict possible corrosivities of mold powder by-products in water solution. Corrosion of various continuous caster components are described, as well as specific corrosion control methods.
