초록

Sand casting is extensively applied both ferrous and non-ferrous metal foundries. Thus tremendous amount of Used Foundry Sand (UFS) is being produced in foundry industry. In this regard, it is required to establish appropriate recycling method of UFS. In order to verify effect of recycling number of cleaning solution, the properties of Regenerated Foundry Sand (RFS) were investigated. UFS was produced in controlled condition using inorganic binder and treated by wet recycling method. Optimized recycling condition which removes binder from sand grains to a sufficient degree was set and UFS was recycled in that manner. Removal efficiency of binder was examined using ion chromatography analysis of used cleaning solution and X-ray fluorescence spectroscopy analysis of RFS. Particle size distribution was investigated by sieve analysis test and surface morphology of RFS was also investigated by using scanning electron microscope.
