Oxide-coated modified homogenized bauxite castable and preparation method thereof
The invention relates to the field of refractory material preparation, particularly to an oxide-coated modified homogenized bauxite castable, which is prepared from the following raw materials in parts by weight: 30-50 parts of homogenized bauxite, 23-35 parts of brown fused alumina, 5-8 parts of silicon carbide, 8-15 parts of spinel powder rich in aluminum and magnesium, 6-10 parts of alumina micro-powder, 2-5 parts of pure calcium aluminate cement, 1.5-9.5 parts of silicon nitride, 1-3 parts of silicon powder, 0.1-0.5 part of aluminum powder, 1-3 parts of silicon dioxide micro-powder, 0.05-0.12 part of organic fiber, 2-4 parts of graphite, 0.5-3 parts of Carbores P, 0.2-0.5 part of a water reducing agent, 3-9 parts of water and 3-5 parts of a nano aluminum hydroxide sol suspension (calculated as a dry material amount) used as a coating material. According to the invention, the erosion and permeation of molten steel and slag components to a material are reduced, and the service life of the castable is prolonged.
本发明涉及耐火材料制备领域，具体涉及一种氧化物涂覆改性均化矾土浇注料，由以下重量份数的原料配制而成：均化铝矾土30~50份，棕刚玉23~35份，碳化硅5~8份，富铝镁尖晶石粉8~15份，氧化铝微粉6~10份，纯铝酸钙水泥2~5份，氮化硅1.5~9.5份，硅粉1~3份，铝粉0.1~0.5份，二氧化硅微粉1~3份，有机纤维0.05~0.12份，石墨2~4份，Carbores P0.5~3份，减水剂0.2~0.5份，水3~9份，纳米氢氧化铝溶胶悬浮液按干料量为3~5份作为涂覆材料。本发明降低了钢水和熔渣成分对材料的侵蚀与渗透，提高了浇注料的使用寿命。
