Corundum-mullite low-cement self-flowing castable and method for repairing hot air outlet of top-combustion hot blast stove by using corundum-mullite low-cement self-flowing castable
The invention discloses a corundum-mullite low-cement self-flowing castable and a method for repairing a hot air outlet of a top combustion hot blast stove by using the same, and belongs to the technical field of amorphous refractory materials. The castable consists of the following components in parts by weight: 5-15 parts of tabular corundum 5-3mm particles, 51-5 parts of tabular corundum 3-1mmparticles, 5-15 parts of tabular corundum 1-3mm particles, 5-15 parts of andalusite 5-3mm particles, 5-15 parts of andalusite 3-1mm particles, 2-10 parts of andalusite 1-3mm particles, 10-20 parts ofbrown fused alumina 200-mesh powder, 1-10 parts of brown fused alumina 325-mesh powder, alumina micro-powder, kyanite, a binding agent, 96 silica powder, a water reducing agent, an explosion-proof agent and an additive. The excellent use performance of the material and a complete and rapid construction method matched with the material can be used for rapidly repairing the problem part, ensuring the subsequent service life of the part and assisting an iron-making system to rapidly reproduce.
一种刚玉莫来石质低水泥自流浇注料及其修复顶燃式热风炉热风出口的方法，属于不定型耐火材料技术领域，该浇注料由如下组分组成：板状刚玉5‑3mm颗粒5‑15重量份、板状刚玉3‑1mm颗粒5‑15重量份、板状刚玉1‑0mm颗粒5‑15重量份、红柱石5‑3mm颗粒5‑15重量份、红柱石3‑1mm颗粒5‑15重量份、红柱石1‑0mm颗粒2‑10重量份、棕刚玉‑200目粉10‑20重量份、棕刚玉‑325目粉1‑10重量份、氧化铝微粉、蓝晶石、结合剂、96硅微粉、减水剂、防爆剂、外加剂。该种材料优良的使用性能及其配套完善快捷的施工方法，可快速修复上述问题部位，并保证该部位后续使用寿命，助力炼铁系统快速复产。
