Influence of Spinel on the Fracture Energy of Refractory Castable
The specific fracture energy of alumina-spinel refractory castables was studied by the wedge-splitting method in this paper.The influence of synthetic spinel on the specific fracture energy of aluminamagnesia refractory castables was investigated.In-situ formation spinel was replaced by sintering spinel as the synthetic spinel.The experimental results indicated that the specific fracture energy and the compressive flesural mechanical properties had the same changing trend with the increase of the synthetic spinel,but the thermal shock resistance of the materials showed the opposite trend.However,the thermal shock resistance was closely associated with the specific fracture energy according to one theory raised by Hasselman.
