High-strength refractory material for local rapid maintenance as well as preparation method and application method of high-strength refractory material
The invention relates to a high-strength refractory material for local rapid maintenance as well as a preparation method and an application method thereof. The high-strength refractory material comprises the following materials in percentage by weight: 60-70% of high-alumina bauxite, 5-15% of corundum, 1-10% of alpha-Al2O3 micro powder, 1-4% of a hardening agent, 1-5% of a sintering agent, 1-5% of an anti-explosion agent and 5-10% of aluminum dihydrogen phosphate powder. Wherein the sintering agent is boron phosphate and/or boron sulfate; the repairing material disclosed by the invention can be used for conveniently repairing the vulnerable part of the aluminum processing reverberatory furnace in manners of smearing and the like, has excellent bonding performance with a body, has excellent strength and non-molten aluminum wetting performance, and solves the technical problem that the vulnerable part of the refractory material of the reverberatory furnace in the current market is difficult to maintain due to the excellent comprehensive performance.
本发明涉及一种局部快速维修用的高强耐火材料及其制备方法、应用方法，包括如下重量百分数材料：高铝矾土60‑70％、刚玉5‑15％、α‑Al2O3微粉1‑10％、硬化剂1‑4％、烧结剂1‑5％、防爆剂1‑5％、磷酸二氢铝粉末5‑10％；其中所述烧结剂为磷酸硼和/或硫酸硼；本发明的修补材料通过涂抹等方式可方便维修铝加工反射炉易损部位，与本体结合性能优异，同时兼具优异强度和不为铝液润湿性能，优异的综合性能解决目前市场上反射炉耐火材料易损部位维修困难的技术问题。
