Reducing Spray Chamber Corrosion Due to the Hydrolysis of Fluoride in Mold Powder

Fluoride-containing compounds in mold powders hydrolyze to hydrofluoric acid when dissolved in spray water in the upper zones of the spray chamber. This acid is very aggressive and causes very high corrosion to the casting machine, leading to shortened life of the machine itself, increasing maintenance costs and causing safety concerns. This presentation will highlight the successful treatment and monitoring of a billet caster that reduced corrosion by 70% using the innovative 3DT for caster.
