Reclamation of ester-cured phenolic resin bonded foundry sands |
| abstract |
A method of preparing a particulate refractory composition for use in the manufacture of foundry molds and cores from spent foundry molds or cores formed of refractory material and an ester-cured phenolic resin binder, the method comprising the steps of breaking up the spent foundry molds or cores, mixing the resulting broken material with a particulate pozzolan additive and subjecting the mixture to a heat treatment at a temperature in the range 450 to 900°. |
