Zirconium self-flowing castable
The invention discloses a zircon self-flowing castable. The zircon self-flowing castable is characterized by comprising aggregate, powder and an admixture, the aggregate is prepared from high-aluminabauxite clinker, sub-white corundum, zirconite and baddeleyite which account for 70-80% of the sum of the mass of the aggregate and the mass of the powder; the powder comprises silica powder accounting for 1-6% of the sum of the mass of the aggregate and the powder, sub-white corundum powder accounting for 1-10% of the sum of the mass of the aggregate and the powder, alumina powder accounting for1-12% of the sum of the mass of the aggregate and the powder, zirconia powder accounting for 2-3% of the sum of the mass of the aggregate and the powder, white mud accounting for 1-10% of the sum of the aggregate and powder, high-alumina bauxite clinker accounting for 0-25% of the sum of agrregate and the power, the mass of the high-alumina cement accounting for 0-3% of the total mass of the aggregate and the powder, and the mass of the pure calcium aluminate cement accounting for 0-6% of the total mass of the aggregate and the powder. The zirconium self-flowing castable is stable in propertyand performance at high temperature and excellent in fire resistance, the cracking resistance can be improved by 2%-3% of zirconium oxide powder, and the fire resistance is integrally improved.
本发明公开了一种锆质自流浇注料，其特征在于：包括：骨料、粉料、掺和料；骨料为占骨料与粉料质量之和的70～80％高铝矾土熟料、亚白刚玉、锆英石、斜锆石，粉料为占骨料与粉料质量之和1％～6％硅微粉、占骨料与粉料质量之和1～10％亚白刚玉粉、占骨料与粉料质量之和1～12％氧化铝粉、占骨料与粉料质量之和2％～3％氧化锆粉、占骨料与粉料质量之和1～10％白泥、占骨料与粉料质量之和0％～25％高铝矾土熟料粉、占骨料与粉料质量之和0～3％高铝水泥、占骨料与粉料质量之和0～6％纯铝酸钙水泥。本发明所述的一种锆质自流浇注料，在高温下性质、性能稳定，耐火性能优异，2％‑3％氧化锆粉能够提高抗龟裂性能，整体提升耐火性能。
