High-strength hot-blast stove high-alumina checker brick and preparation process thereof
The invention relates to the technical field of hot-blast stove checker bricks. The invention discloses a high-strength hot-blast stove high-alumina checker brick. The high-strength hot-blast stove high-alumina checker brick comprises the following raw materials in parts by weight: 10 to 20 parts of high-alumina bauxite with a particle size of 3 to 5 mm; 20 to 30 parts of andalusite with a particle size of 1 to 3 mm; 15 to 20 parts of corundum with the granularity of 0 to 1mm; 5-10 parts of an aluminum oxide raw material with a particle size of less than 0.088 mm; 10-20 parts of andalusite with the particle size being lower than 0.088 mm, 4-6 parts of activated aluminum oxide micro powder with the particle size being lower than 0.044 mm, 8-10 parts of corundum fine powder with the particlesize being lower than 0.044 mm and 5-8 parts of Guangxi white mud with the particle size being lower than 0.088 mm. The invention discloses the high-strength hot-blast stove high-alumina checker brick and a preparation process thereof. The preparation process comprises the following steps: adding a premixed fine powder matrix containing an aluminum oxide raw material, and stirring and mixing withweighed and proportioned raw materials; according to the method, the strength of green bricks can be improved, the defect rate of the green bricks in the transferring process is reduced, the production cost is reduced, the economic benefits are improved, the strength performance of the sintered high-aluminum checker brick is improved by 40%, and therefore the effect that the strength of the sintered high-aluminum checker brick is high is achieved.
本发明涉及热风炉炉格子砖技术领域，且公开了一种高强度热风炉高铝格子砖，包括以下重量份数配比的原料：粒度3‑5mm的高铝矾土10‑20份，粒度1‑3mm的红柱石20‑30份，粒度0‑1mm的刚玉15‑20份，粒度低于0.088mm的矾土生料5‑10份，粒度低于0.088mm的红柱石10‑20份，粒度低于0.044mm的活性氧化铝微粉4‑6份，粒度低于0.044mm的刚玉细粉8‑10份，粒度低于0.088mm的广西白泥5‑8份。该高强度热风炉高铝格子砖及其制备工艺，通过加入含有矾土生料的预混细粉基质与称重配比好的原料进行搅拌混合，可以使得砖坯的强度得到提高，降低砖坯在转运过程中的缺损率，降低生产成本，提高经济效益，且使得砖烧结后的高铝格子强度性能提升40％，从而达到烧结后高铝格子砖强度高的效果。
