High-purity corundum refractory brick and manufacturing process thereof
The invention relates to the technical field of refractory brick manufacturing, and discloses a high-purity corundum refractory brick and a manufacturing process thereof. The refractory brick is prepared by mixing the following components: tabular corundum aggregate, boric oxide, aluminum hydroxide, a whisker growth promoter and alumina sol according to a ratio of (5-15): (1-5): (0.5-2): 1: (2-6). The manufacturing process comprises the following steps: S1, preparing aluminum sol; s2, providing tabular corundum aggregate; s3, adding boric oxide, aluminum hydroxide and a whisker growth promoter into the aluminum sol to obtain a mixture; s4, adding tabular corundum aggregate into the mixture to obtain a brick material; s5, feeding the brick material into a mold, pressing and baking, and demolding to obtain a green brick; s6, sintering the green brick to obtain the refractory brick. The firing temperature of the high-purity corundum refractory brick can be reduced, and the purity and high-temperature use performance of the refractory brick can be improved.
本发明涉及耐火砖制作技术领域，其公开了一种高纯刚玉质耐火砖及其制作工艺。前述耐火砖具备如下组分：板状刚玉骨料、氧化硼、氢氧化铝、晶须生长促进剂和铝溶胶按5~15:1~5:0.5~2:1:2~6的比例混炼得到耐火砖。制作工艺包括以下步骤：S1制备铝溶胶；S2提供板状刚玉骨料；S3向铝溶胶中加入氧化硼、氢氧化铝和晶须生长促进剂，得到混炼物；S4向混炼物中加入板状刚玉骨料得到砖料；S5将砖料送入模具，压制烘烤后脱模得到砖坯；S6砖坯烧结得到耐火砖。本发明可降低高纯刚玉质耐火砖的烧成温度，提高耐火砖的纯度以及高温使用性能。
