摘要
The microstructure of high chrome bricks made at different sintering temperature are analyzed by SEM . The results indicate that the sintering temperature of high chromebricks has an optimum range , it is not the higher, the better, The high chrome bricks made at this -sintering temperature have the moderate crystal six in the matrix and of dense structure. The closed bonding structure could be obtained between grains and matrix and no crackle occurred.The high chrome bricks with this microstructure have the best dynamic properties.
