Wear-resistant super-compact high-alumina brick and production process thereof
The invention provides a wear-resistant super-compact high-alumina brick and a production process thereof, and relates to the technical field of refractory materials, the wear-resistant super-compact high-alumina brick comprises the following raw materials by weight: 50-75 parts of bauxite, 20-35 parts of andalusite fine powder, 2-7 parts of zirconium carbide fine powder, 2-10 parts of silicon oxide micro powder, and 8-17 parts of an organic binder. the wear-resistant super-compact high-alumina brick comprises the following raw materials in parts by weight: 65 parts of bauxite, 30 parts of andalusite fine powder, 5 parts of zirconium carbide fine powder, 6 parts of silicon oxide micro powder and 13 parts of an organic binding agent. The production process comprises the following steps: step 1, mixing and stirring the bauxite, the andalusite fine powder, the zirconium carbide fine powder, the silicon oxide micro powder and the organic binding agent in proportion for 10-20 minutes to form a blank; according to the high-alumina brick provided by the invention, under a wear test, the wear rate of the high-alumina brick is 8.3%-10.6% which is lower than that of the high-alumina brick in the prior art, and the density is 25.9 g/cm < 3 >-26.3 g/cm < 3 > which is higher than that of the high-alumina brick in the prior art, so that the high-alumina brick is good in wear resistance and high in density.
本发明提供耐磨超致密高铝砖及其生产工艺，涉及耐火材料技术领域，该耐磨超致密高铝砖及其生产工艺包括以下按照重量份计的原料：铝矾土50～75份，红柱石细粉20～35份，碳化锆细粉2～7份，氧化硅微粉2～10份，有机结合剂8～17份，包括以下按照重量份计的原料：铝矾土65份，红柱石细粉30份，碳化锆细粉5份，氧化硅微粉6份，有机结合剂13份，包括以下步骤：步骤一，将铝矾土、红柱石细粉、碳化锆细粉、氧化硅微粉和有机结合剂按比例混合搅拌10～20分钟形成坯料；本发明提供的高铝砖，在磨损测试下高铝砖的磨损率在8.3%～10.6%，小于现有技术的高铝砖，而且密度为25.9 g/cm3～26.3 g/cm3，大于现有技术的高铝砖，因此耐磨性好，密度高。
