| titleOfInvention | A kind of magnesia-aluminum spinel brick for co-processing cement kiln and its preparation method and application |
| abstract | The invention belongs to the technical field of refractory materials, and in particular relates to a magnesia-alumina spinel brick for co-processing cement kilns and a preparation method and application thereof. The magnesia-alumina spinel brick is made by using flotation magnesia, high-purity magnesia, and fused magnesia spinel as main raw materials through high-temperature treatment; the flotation magnesia, high-purity magnesia, and fused magnesia The mass ratio of aluminum spinel is (54-65): (18-28): (12-25). The magnesia-aluminum spinel brick of the present invention not only has suitable room temperature compressive strength and load softening temperature, but also has higher bulk density and lower apparent porosity, and has a higher degree of sintering densification, which can effectively reduce the The penetration of erosive substances has better corrosion resistance; at the same time, it also has higher thermal shock stability, high temperature flexural strength and high temperature toughness; the magnesium aluminum spinel brick not only has excellent performance, but also has low cost. The cost performance makes it more widely used. |
