Tundish dry material and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a tundish dry material and a preparation method thereof. Comprising 80-92 parts of magnesite, 3-5 parts of resin powder, 2-5 parts of a ferro-silicon nitride and boron carbide composite additive and 0.5-8 parts of a burning promoter, through tundish dry material design, the problems that in the prior art, traditional antioxidants including Al powder, Si powder and the like can improve the oxidation resistance of a product to a certain extent by adding a proper amount, however, under the high-temperature condition, aluminum powder is active in chemical property and violently reacts with steel slag, a formed sintering layer is not ideal, and the service life of the product is prolonged are solved. The corrosion resistance and the permeability resistance of the product are influenced.
本发明涉及耐火材料技术领域，尤其是涉及一种中间包干式料及其制备方法；包括镁砂80‑92份、树脂粉3‑5份、氮化硅铁和碳化硼复合添加剂2‑5份和促烧剂0.5‑8份；通过中间包干式料设计以解决现有技术中存在的传统的抗氧化剂有Al粉、Si粉等，适量添加能够一定程度上提高产品的抗氧化性能，然而在高温条件下，铝粉化学性质活泼，与钢渣反应剧烈，形成烧结层不理想，影响产品的耐侵蚀性和抗渗透性的技术问题。
