Siliceous insulating brick for coke oven and production process thereof
The invention relates to the technical field of bricks for thermal equipment in metallurgy, chemical industry and the like, and discloses a siliceous heat-insulating brick for a coke oven for the first time in China, which comprises the following components in percentage by weight: 75%-80% of silica and silicon dioxide, 10%-15% of silica powder, 0.1%-0.2% of sodium oxide, 2%-6% of kyanite, 2%-6% of mullite, 1%-3% of corundum, and 5%-10% of silica sol. According to the siliceous heat-insulating brick for the coke oven and the production process of the siliceous heat-insulating brick, the corundum is added, so that the thermal shock resistance is improved to a certain extent, the high-temperature creep resistance is relatively good, the thermal stability of the siliceous heat-insulating brick is low, the mullite and the corundum are added, the heat resistance of the siliceous heat-insulating brick is further ensured, the strength of the siliceous heat-insulating brick is improved, the siliceous heat-insulating brick can be directly contacted with flame to be used as a lining structure material, and guarantees are provided for the design of a novel heat-insulating and energy-saving structure of a coke oven and the structural transformation of a traditional high-temperature kiln.
本发明涉及冶金、化工等热工设备用砖技术领域，且国内首次公开了焦炉用硅质隔热砖，该材料配方的组分及重量成分组成包括：硅石及二氧化硅类的：75％‑80％、硅微粉10％‑15％，氧化钠：0.1％‑0.2％、兰晶石：2％‑6％、莫来石：2％‑6％、刚玉：1％‑3％；硅溶胶5％‑10％。该焦炉用硅质隔热砖及其生产工艺，通过添加刚玉，保证热震性能得到一定的提高，高温抗蠕变性较好，保证硅质隔热耐火砖的热稳定性能低，通过增添莫来石和刚玉，进一步保证硅质隔热砖的耐热性能，提高了硅质隔热砖的强度，该硅质隔热砖可直接接触火焰作为内衬结构材料使用，为炼焦炉新的隔热节能结构的设计以及传统高温窑炉结构改造提供保障。
