Anti-burst high-strength light corundum castable and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to an anti-burst high-strength light corundum castable and a preparation method thereof. The corundum castable comprises 45-52% of high-purity tabular corundum, 20-28% of corundum hollow spheres, 3-8% of alumina micro powder, 2-6% of zirconium silica micro powder, 7-12% of pure calcium aluminate cement and 2-7% of an anti-explosion agent; the coating further comprises an inorganic binding agent. The anti-burst high-strength light corundum castable has high compressive strength, low heat conductivity coefficient and good thermal shock stability, the structural stability of the castable in the using process can be effectively guaranteed through the anti-explosion agent and the organic binding agent, the burst phenomenon can be avoided, and the service life of the castable is prolonged.
本发明属于耐火材料技术领域，具体涉及一种防爆裂高强轻质刚玉浇注料及其制备方法。所述刚玉浇注料包括高纯板状刚玉45‑52％，刚玉空心球20‑28％，氧化铝微粉3‑8％，锆质硅微粉2‑6％，纯铝酸钙水泥7‑12％，防爆剂2‑7％；还包括无机结合剂。该防爆裂高强轻质刚玉浇注料具有较高的耐压强度、较低的导热系数和较好的热震稳定性能，利用防爆剂和有机结合剂不仅能有效确保材料在使用过程中的结构稳定性，还可避免出现爆裂的现象，提高材料的使用寿命。
