The invention relates to the technical field of castable, in particular to high-performance tundish cover castable based on high-aluminum ceramic chip recycled aggregate and a preparation method of the high-performance tundish cover castable. The castable comprises high-aluminum ceramic chip recycled aggregate, modified hollow alumina microspheres, andalusite and other components, and through roasting stabilization treatment of the recycled aggregate and multi-layer coating modification of the microspheres, the problems of poor heat preservation property and concentrated thermal stress caused by high doping amount of the recycled aggregate are solved. The andalusite cooperates with the modified microbeads to optimize aggregate-andalusite-microbead three-phase interface combination by virtue of the low-expansion characteristic and the active surface, so that the thermal shock resistance and the structural compactness are enhanced. The product has excellent heat preservation and heat insulation performance, high strength and slag corrosion resistance, resource efficient utilization of waste high-aluminum ceramic chips is achieved, and the service life of the tundish cover is prolonged.

The invention belongs to the technical field of advanced ceramic material preparation, and particularly discloses high-performance nearly-spherical zirconium oxide feeding powder and a preparation method thereof, and the method comprises the following steps: (1) preparing composite precursor liquid; (2) graded controllable thermal conversion; and (3) post-treatment: carrying out heat treatment on the product obtained in the step (2) in an oxidizing atmosphere at 500-700 DEG C for 0.5-3 hours to obtain the zirconium oxide powder. The special structure powder with the dense outside and the inner holes is prepared. The smooth and compact surface endows the powder with excellent fluidity; the internal uniform closed nano-pores properly reduce the particle density and further facilitate flowing, and more importantly, the pores can partially absorb a binder during feed preparation and play roles in'internal stress buffering 'and binder distribution optimization, so that higher powder loading capacity is allowed under the same viscosity, and the feed preparation efficiency is improved. Or lower viscosity and better rheological property can be obtained under the same loading capacity.
