Silicon carbide-magnesium aluminate spinel refractory product and preparation method thereof
The invention belongs to the technical field of novel refractory materials, and particularly relates to a silicon carbide-magnesium aluminate spinel refractory product and a preparation method thereof. The silicon carbide-magnesium aluminate spinel refractory product is prepared from the following raw materials in percentage by mass: 50%-70% of silicon carbide with the particle size of 0.1-3mm, 10%-30% of magnesium aluminate spinel powder with the particle size of 0.045-1mm, 1%-10% of a binding agent, 1%-10% of aluminum oxide micro powder, 1%-10% of passivated metal aluminum powder, 0.1%-10% of an additive and a water reducing agent which accounts for 0.1%-1% of the total mass of the raw materials, the binding agent is light calcined magnesia powder; the binding agent is light calcined magnesia powder. The silicon carbide-magnesium aluminate spinel refractory product prepared by the invention is high in strength and good in slag corrosion resistance and permeability, and also has the advantages of convenience in construction, long construction time during pouring, low production energy consumption and the like.
本发明属于耐火新材料技术领域，具体涉及一种碳化硅‑镁铝尖晶石耐火制品及其制备方法。按质量百分含量计，所述碳化硅‑镁铝尖晶石耐火制品的原料组成为：粒度为0.1～3 mm的碳化硅50%～70%、粒度为0.045～1 mm的镁铝尖晶石粉10%～30%、结合剂1%～10%、氧化铝微粉1%～10%、钝化金属铝粉1%～10%和添加剂0.1%～10%，外加占上述原料总质量0.1%～1%的减水剂；所述结合剂为轻烧氧化镁粉；所述结合剂为轻烧氧化镁粉。本发明制备的本发明的碳化硅‑镁铝尖晶石耐火制品强度高，抗熔渣侵蚀和渗透性能好，同时还具备施工便捷、浇注时可施工时间长、生产能耗低等优点。
