Thermal regeneration method of foundry sand |
| abstract |
The present invention relates to a method for reclaiming waste foundry sand contaminated with water glass, wherein the reclaimed method is provided with a waste foundry sand to which a binder based on water glass (the binder is added with metal oxide fine particles) is attached. Undergoes a heat treatment, wherein the waste foundry sand is heated to a temperature of 200 ° C. or higher, whereby a reclaimed foundry sand is obtained. The invention also relates to a reclaimed foundry sand obtained by the process. |
