Aluminum oxide-silicon carbide-carbon castable with high hot strength
The invention relates to an aluminum oxide-silicon carbide-carbon castable with high hot strength. According to a technical scheme, the aluminum oxide-silicon carbide-carbon castable comprises the following components in percentage by weight: 58-62 wt% of compact corundum aggregate, 6-10 wt% of silicon carbide particles, 2-3 wt% of spherical asphalt, 4-10 wt% of aluminum oxide micro-powder, 4-5 wt% of silicon dioxide micro-powder, 7-10 wt% of silicon carbide powder, 1 to 1.5 wt% of silicon powder, 6-9 wt% of fine compact corundum powder and 0.1-0.2 wt% of polyacrylic acid. A preparation methodfor the castable comprises the following steps: subjecting the above components to burdening and mixing according to the respective contents; and adding water accounting for 3-3.3 wt% of the total mass of the components, performing uniform stirring, carrying out vibration molding, conducting natural drying for 24 hours, and carrying out heat treatment at 110 DEG C for 24 hours to obtain the aluminum oxide-silicon carbide-carbon castable with high hot strength. The castable has the characteristics of high hot strength, high density and good volume stability.
