Title:
RECYCLING FOR RAW MATERIAL FROM USED REFRACTORY
Document Type and Number:
Japanese Patent JP3781316
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a method for recycling a raw material from a used refractory, capable of recovering a high-purity raw material from a used refractory.
SOLUTION: This method for recycling a raw material from a used refractory comprises coarsely grinding the used refractory, applying frictional force, pressing force and/or impact force to the ground particles and recovering the original raw material part so as to reuse a refractory raw material. Preferably, the refractory raw material is marked so as to distinguish the qualities of the refractory before use. Preferably, the used refractory contains carbon.
