Embodiment 1
[0028] An ultrafine kyanite refractory castable, the raw material and content of the ultrafine kyanite refractory castable are: 30% high alumina aggregate with a particle size of 3-5mm; 12% with a particle size of 1 ~3mm high-alumina bauxite aggregate; 21% high-alumina bauxite aggregate with a particle size of 0-1mm; 5% ultrafine kyanite (5μm, alumina content ≥ 50%, kyanite phase ≥ 70 %, the same below), 8% of α-Al2O3; 7% of sub-white corundum powder; 12% of calcium aluminate cement; 4.95% of barium sulfate; 0.05% of sodium hexametaphosphate. (Wherein the weight percentage of aluminum in the high-alumina bauxite aggregate is ≥75%; α-Al 2 o 3 Middle Al 2 o 3 Mass percentage ≥ 99%, particle size ≤ 320 mesh; sub-white corundum powder l 2 o 3 Mass percentage ≥ 98%, particle size ≤ 320 mesh; Al in calcium aluminate cement 2 o 3 Mass percentage ≥ 50%; BaSO in barium sulfate 4 Mass percentage ≥ 95%, particle size ≤ 200 mesh, the same below)

Embodiment 2
[0031] An ultrafine kyanite refractory castable, the raw material and content of the ultrafine kyanite refractory castable are: 40% high alumina aggregate with a particle size of 3-5 mm; 10% with a particle size of 1 ~3mm high alumina bauxite aggregate; 30% high bauxite aggregate with a particle size of 0~1mm; 3% ultrafine kyanite (10μm), 1% α-Al2O3; 3% sub-white Corundum powder; 5% calcium aluminate cement; 7% barium sulfate; 1% sodium hexametaphosphate.
[0032] Put the micron-sized fine powder in the ingredients of ultrafine kyanite, α-Al2O3 and sub-white corundum powder into a mixer such as a conical mixer or an inclined high-speed mixer, and make the micron-sized fine powder under high-speed mixing conditions. The fine powder disperses the ultrafine kyanite highly evenly to obtain a uniformly dispersed premixed powder. In the later stage, it will be put into the planetary mixer together with other raw materials (including aggregate, fine powder, admixture, etc.) for remi...
Embodiment 3
[0034] An ultrafine kyanite refractory castable, the raw material and content of the ultrafine kyanite refractory castable are: 17% high alumina aggregate with a particle size of 3-5 mm; 35% with a particle size of 1 ~3mm high-alumina bauxite aggregate; 11% high-alumina bauxite aggregate with a particle size of 0-1mm; 10% ultrafine kyanite (8μm), 11% α-Al2O3; 4% sub-white Corundum powder; 7% calcium aluminate cement; 2% barium sulfate; 3% sodium aluminate.
[0035] Put the micron-sized fine powder in the ingredients of ultrafine kyanite, α-Al2O3 and sub-white corundum powder into a mixer such as a conical mixer or an inclined high-speed mixer, and make the micron-sized fine powder under high-speed mixing conditions. The fine powder disperses the ultrafine kyanite highly evenly to obtain a uniformly dispersed premixed powder. In the later stage, it will be put into the planetary mixer together with other raw materials (including aggregate, fine powder, admixture, etc.) for rem...
