Wear-resistant castable for high-temperature wear part of thermal kiln lining and preparation method of wear-resistant castable
The invention belongs to the technical field of refractory materials, and particularly relates to a wear-resistant castable for a high-temperature wear part of a thermotechnical kiln lining and a preparation method of the wear-resistant castable. The wear-resistant castable comprises 58-65% of fused zirconia corundum, 10-15% of silicon carbide, 2-7% of alumina micro powder, 5-10% of zirconia, 5-12% of pure calcium aluminate cement and 2-7% of an antioxidant. The coating further comprises an inorganic binding agent. The wear-resistant castable for the high-temperature wear-resistant part of the thermotechnical kiln lining has relatively high compression strength, relatively low wear-resistant coefficient and relatively good thermal shock stability, high toughness and wear resistance of the material in the using process are effectively ensured by utilizing the fused alumina zirconia, the silicon carbide and the zirconium oxide, the phenomena of cracking and wear are avoided, and the service life of the material is prolonged.
本发明属于耐火材料技术领域，具体涉及一种热工窑炉内衬高温磨损部位用耐磨浇注料及其制备方法。所述耐磨浇注料包括电熔锆刚玉58‑65％，碳化硅10‑15％，氧化铝微粉2‑7％，氧化锆5‑10％，纯铝酸钙水泥5‑12％，抗氧化剂2‑7％；还包括无机结合剂。该热工窑炉内衬高温磨损部位用耐磨浇注料具有较高的耐压强度、较低的耐磨系数和较好的热震稳定性能，利用锆刚玉、碳化硅和氧化锆有效确保材料在使用过程中的高韧性和抗耐磨性能，避免出现崩裂和磨损现象，提高材料的使用寿命。
