Brick for rotary kiln firing zone and preparation method thereof
The invention discloses a brick for a rotary kiln firing zone and a preparation method thereof. The brick is prepared from the following raw materials in parts by weight: 25-35 parts of magnesium aluminate spinel with the particle size of 3-5 mm, 20-30 parts of magnesia with the particle size of 1-3 mm, 5-15 parts of magnesium aluminate spinel with the particle size of less than or equal to 1 mm,8-16 parts of magnesia with the particle size of 180 meshes, 6-10 parts of pretreated metal aluminum powder with the particle size of 350 meshes, 4-6 parts of pretreated magnesium powder with the particle size of 200 meshes; and 6-10 parts of alumina micro-powder with the particle size of 5-6 [mu]m; wherein the weight of the pulp waste liquid is 3-4% of the total weight of the raw materials. The preparation method is simple and easy to implement, the prepared brick for a rotary kiln firing zone is high in strength, fibers formed in the brick have a toughening effect, the thermal shock resistance of the fired brick is effectively improved, cracking and peeling of the fired brick are prevented, and the service life of a lining of the rotary kiln firing zone made of lime, cement and the likeis prolonged.
一种回转窑烧成带用砖及其制备方法，其原料组成和重量份数如下：粒度为3～5mm的镁铝尖晶石25份～35份，粒度为1～3mm的镁砂20份～30份，粒度≤1mm的镁铝尖晶石5份～15份，粒度为‑180目的镁砂8份～16份，预处理过的粒度为‑350目的金属铝粉6份～10份，预处理过的粒度为‑200目的金属镁粉4份～6份；粒度为5～6μm的氧化铝微粉6份～10份；按照上述原料总重量的3％～4％加入纸浆废液。本发明制备方法简单，易于实现，所制备的回转窑烧成带用砖强度高，砖中形成的纤维具有增韧作用，有效提高烧成砖的抗热震性能，防止其开裂和剥落，提高石灰、水泥等回转窑烧成带的内衬服役寿命。
