| Abstract: | According to chemical thermodynamics and thermal stress theory,the study on thechecmical and mechanical damage of Si3N4-bonded SiC refractory used in blast furnace (BF)was made, and on the other hand, the characteristics of the resistance to oxidation, alkali erosion and thermal shock damage of this kind of brick lining for BF ward analyst under the conditions of the actual BF operation. On this basis,the technical direction and measures to control alkali-erosion, to decrease thermal shock damage and to improve the using efficiency ofSi3N4-bonded SiC bricks for BF were discussed. |
