摘要：
It was introduced that the principle of the thermal reclamation for used resin bonded sands and fluidized bed reclamation equipment. It is founded by studying that the index of sands shape, gas evolution, thermal expansibility are lower, the degree of collecting, tensile strength are higher and the grain shape is more round of reclamation molding sand then those of new sands. Foundry process properties of the thermal reclamation sands are better than that of the same kind new sands.
