Low-creep pipeline brick for hot blast stove and preparation method thereof
The invention discloses a low-creep pipeline brick for a hot blast stove and a preparation method of the low-creep pipeline brick. The low-creep pipeline brick comprises the following raw materials inparts by weight: 60-80 parts of tabular corundum, 3-20 parts of alumina powder, 5-25 parts of sillimanite powder, 0-25 parts of andalusite powder and 3-15 parts of Guangxi white mud. The preparationmethod comprises the following steps: mixing tabular corundum, alumina powder, sillimanite powder and andalusite powder in proportion, uniformly stirring, adding a proper amount of water, stirring for10 minutes, adding Guangxi white mud, mixing and stirring for 10 minutes, and after the mixed pug is pressed and formed, drying and sintering to obtain a finished product. The low-creep pipeline brick for the hot blast stove has the advantages of low apparent porosity, high compression strength and low creep, and the preparation method is simple, low in cost and convenient for batch production.
本发明的一种用于热风炉的低蠕变管道砖及其制备方法，包括以下重量份数配比的原料：板状刚玉60‑80份，氧化铝粉3‑20粉，硅线石粉5‑25份，红柱石粉0‑25份，广西白泥3‑15份。按配比将板状刚玉、氧化铝粉、硅线石粉和红柱石粉混合并搅拌均匀后，加入适量水并搅拌十分钟，再加入广西白泥混合搅拌十分钟；将混合泥料压制成型后，进行干燥和烧结制得成品。本发明的用于热风炉的低蠕变管道砖具有显气孔率低、耐压强度高、低蠕变的优点，且其制备方法简单、成本低，便于批量生产。
