Bottom creep clay brick for hot-blast stove and preparation method thereof
The invention relates to the technical field of hot-blast stove shaped refractory materials. The invention discloses a bottom creep clay brick for a hot blast stove. The brick comprises the followingraw materials in parts by weight: 5-15 parts of high-aluminum flint clay with the particle size of 3-5 mm, 20-30 parts of high-alumina flint clay with the particle size being 1-3 mm, 15-20 parts of 45bauxite with the particle size being 0-1 mm, 15-25 parts of high-alumina flint clay with the particle size being lower than 0.088 mm, 10-20 parts of andalusite with the particle size being lower than0.088 mm and 8-12 parts of first-grade clay powder with the particle size of less than 0.088 mm. According to the bottom creep clay brick for a hot-blast stove and a preparation method thereof, the creep resistance of the low-creep clay brick is improved; meanwhile, under the condition that other performance indexes are not reduced, the creep resistance of the low-creep clay brick (containing checker bricks) for the hot blast stove is improved; the creep resistance is stable, normal use of the hot blast stove is guaranteed; the preparation method of the product is reduced, and industrial popularization is easy; by adopting the high-alumina flint clay, yield supply is stable, product quality control is facilitated, and the production cost is reduced.
本发明涉及热风炉定型耐火材料技术领域，且公开了一种热风炉用底蠕变黏土砖，包括以下重量份数配比的原料：粒度3‑5mm的高铝焦宝石5‑15份，粒度1‑3mm的高铝焦宝石20‑30份，粒度0‑1mm的45铝矾土15‑20份，粒度低于0.088mm的高铝焦宝石15‑25份，粒度低于0.088mm的红柱石10‑20份，粒度低于0.088mm的一级粘土粉8‑12份。该热风炉用底蠕变黏土砖及其制备方法，不仅提高了低蠕变粘土砖的抗蠕变性能，同时在不降低其它性能指标的情况下，提高热风炉用低蠕变粘土砖(含格子砖)的抗蠕变性能，同时抗蠕变性能稳定，保障了热风炉的正常使用，同时制品制备方法降低，易于工业推广，通过采用高铝焦宝石，其产量供应稳定有利于产品质量管控，有利于降低生产成本。
