Patent

CA 2678292

The invention relates to a method for regenerating used foundry sand, which is contaminated with soluble glass, wherein: used foundry sand is provided, which is tainted with a binding agent made of the soluble glass, to which a particle-shaped metal oxide is added; and the used foundry sand is subjected to a thermal treatment, wherein the foundry sand is heated to a temperature of at least 200ºC, thereby obtaining regenerated foundry sand. The invention further relates to regenerated foundry sand, as that obtained from using the method.

L'invention concerne un procédé de retraitement de sables de fonderie usagés contaminés par des silicates de potassium. On prend un sable de fonderie usagé qui est chargé d'un liant à base de silicate de potassium auquel on ajoute un oxyde métallique particulaire puis le sable de fonderie usagé est soumis à un traitement thermique, le sable de fonderie étant chauffé à une température d'au moins 200°C et on obtient ainsi un sable de fonderie régénéré. L'invention concerne enfin un sable de fonderie retraité, comme obtenu par ledit procédé.
