Zirconium oxide light heat-preservation refractory product
The invention belongs to the field of refractory materials, and relates to a zirconium oxide light heat-preservation refractory product. Raw materials of the zirconium oxide light heat-preservation refractory product are composed of aggregate and a matrix. The aggregate is composed of fused zirconium oxide hollow sphere particles with particle sizes larger than 0.074 mm and sintered zirconium oxide porous lightweight aggregate particles. The matrix is composed of a zirconium oxide powder mixture with a particle size smaller than or equal to 0.074 mm. The fused zirconium oxide hollow sphere particles account for 35%-50% of the total mass of the refractory product, the sintered zirconium oxide porous lightweight aggregate particles account for 15%-30% of the total mass of the refractory product, and zirconium oxide powder accounts for 20%-40% of the total mass of the refractory product. The zirconium oxide light heat-preservation refractory product is a refractory material with a certainshape at normal temperature, and is sintered at the highest sintering temperature of 1600-1800 DEG C in an oxidizing atmosphere. According to the invention, rolling and sliding of the hollow sphere particles under the action of external force at high temperature are delayed, and structural stability is improved.
本发明属于耐火材料领域，涉及一种氧化锆轻质保温耐火制品。涉及的氧化锆轻质保温耐火制品原料包括骨料和基质两部分；骨料由粒度＞0.074mm的电熔氧化锆空心球颗粒和烧结氧化锆多孔轻质骨料颗粒组成；基质由粒度≤0.074mm的氧化锆粉料混合物组成；电熔氧化锆空心球颗粒占耐火制品总质量的35%～50%，烧结氧化锆多孔轻质骨料颗粒占耐火制品总质量的15%～30%，氧化锆粉料占耐火制品总质量的20%～40%；氧化锆轻质保温耐火制品是一种常温下具有一定形状的耐火材料，在最高烧成温度1600℃～1800℃、氧化气氛下进行烧成。本发明延缓了高温下空心球颗粒受外力产生的滚动、滑移，提升了结构稳定性。
