Application of rare earth antioxidant in preparation of carbon-containing refractory material
The invention belongs to the technical field of refractory materials, and particularly relates to application of a rare earth antioxidant in preparation of a carbon-containing refractory material. Specifically, the mass fraction of the rare earth antioxidant is 1-3% of the mass of the carbon-containing refractory material, the mass fraction of the rare earth elements is larger than or equal to 1% of the mass of the carbon-containing refractory material, and the rare earth antioxidant is formed by mixing rare earth metal powder or rare earth metal powder and metal aluminum powder. The rare earth antioxidant provided by the invention can effectively inhibit the formation of an oxidation decarburization layer in the carbon-containing refractory material, improve the oxidation resistance of the carbon-containing refractory material and reduce the oxidation speed of the carbon-containing refractory material. Meanwhile, the service life of the carbon-containing refractory material can be remarkably prolonged, the high-temperature performance of the carbon-containing refractory material can be remarkably improved, and the carbon-containing refractory material has high popularization value and potential application prospects.
本发明属于耐火材料工艺领域，具体涉及一种稀土抗氧化剂在含碳耐火材料制备中的应用。具体为所述稀土抗氧化剂以质量分数计为含碳耐火材料质量的1～3％，其中稀土元素以质量分数计大于等于含碳耐火材料质量的1％，所述稀土抗氧化剂由稀土金属粉或稀土金属粉和金属铝粉混合组成。由本发明提供的稀土抗氧化剂能够有效抑制含碳耐火材料中氧化脱碳层的形成，可以提高含碳耐火材料的抗氧化性，降低含碳耐火材料的氧化速度。同时可显著提高含碳耐火材料的使用寿命和高温性能，具有较高的推广价值和潜在的应用前景。
