Abstract:The feature of the Ester-hardened Alkaline Phenolic Resin used Sand, crucial technique encountered in the course of the sand reclamation and the reasonable choice of reclamation methods are presented in this paper. The results of a large quantities of tests indicate that by using combined reclamation method, this technique may be most effective in reclaiming phenolic/ester sand, the quality of the reclaimed sand can measure up to that of new sand, which is of great application value economically and technically.
Keywords:Ester-hardened Alkaline Phenolic Resin used Sand  reclamation technique  combined reclamation method
