Max phase-boron nitride composite ceramic side seal plate for thin-strip casting and manufacturing method of Max phase-boron nitride composite ceramic side seal plate
The invention discloses a Max phase-boron nitride composite ceramic side seal plate for thin-strip casting and a manufacturing method of the Max phase-boron nitride composite ceramic side seal plate. The side seal plate comprises the following components in percentage by mass: 40-70% of h-BN powder, 10-30% of Max phase powder, 5-20% of AlN powder, 5-20% of AlB2 powder and 0.5-5% of Al2O3 powder. The manufacturing method comprises the following steps: 1) preparing Max phase powder; 2) preparing mixed slurry: namely mixing the h-BN powder, the Max phase powder, the AlN powder, the AlB2 powder and the Al2O3 powder in percentage by mass and then adding a mixed solvent to mix and fully and uniformly mixing the mixture to obtain mixed slurry; 3) preparing mixed powder; and 4) sintering the mixed powder. According to the method disclosed by the invention, the ceramic side seal plate for double roll thin-strip casting is manufactured by using a ceramic formula. The prepared side seal plate has the characteristics of being high in compactness and high in rupture strength. The compactness is 93-98%, the rupture strength at the room temperature reaches 300-500MPa, the strength of the side seal plate in the using process is fully guaranteed, and the side seal plate is not hardened.
