Description

一种新型焦炉高强漂珠隔热砖及其制备方法
技术领域
本发明涉及隔热砖技术领域，特别是涉及一种新型焦炉高强漂珠隔热砖及其制备方法。
背景技术
焦炉用于使煤炭化以生产焦炭，焦炉砌体蓄热损失和炉体表面散热损失，一般约占燃料消耗的24-45％，用轻质隔热保温砖作炉体结构的材料，不仅可节能降耗、减轻炉体自重，简化窑炉结构，降低工作环境温度并改善劳动条件，且由于蓄热量的降低，可实现窑炉的快速升温和冷却，提高了窑炉的生产效率。
隔热砖是用耐火黏土或其他耐火原料烧制成的具有一定形状和尺寸的耐火材料，能耐高温。近年来，国内隔热砖生产工艺发展迅速，市场上出现了种类繁多、性能各异的隔热砖。但是现在国内焦炉用漂珠砖强度低，技术不过关，存在耐火性、抗热冲击性和抗热震稳定性差等缺陷。
发明内容
本发明的目的之一在于针对现有技术的不足，而提供一种强度高、耐火性、抗热冲击性和抗热震稳定性好的新型焦炉高强漂珠隔热砖。
本发明解决其技术问题所采用的技术方案是：
一种新型焦炉高强漂珠隔热砖，所述漂珠隔热砖由以下重量的原料制备而成：白石墨15-30％，氧化铝粉5-15％，粘土10-20％，莫来石粉10-25％，氧化锆粉5-15％，漂珠25-35％，木屑2-5％，粘结剂5-10％，减水剂1-5％和水10-15％。
作为一种改进，所述漂珠隔热砖由以下重量的原料制备而成：白石墨20-25％，氧化铝粉8-12％，粘土8-13％，莫来石粉15-20％，氧化锆粉8-12％，漂珠28-30％，木屑3-5％，粘结剂6-8％，减水剂3-5％和水12-15％。
作为一种改进，所述氧化铝粉的粒度为0.073mm，所述莫来石粉的粒度为0.088mm，所述氧化锆粉的粒度为0.020-0.060mm，所述漂珠的粒度为0.425-0.633mm。
作为一种改进，所述粘结剂为酚醛树脂、脲醛树脂或聚醋酸乙烯树脂中的一种或两种以上混合物。
作为一种改进，所述减水剂为三聚磷酸钠、硅酸钠、六偏磷酸钠或粉末聚羧酸酯。
本发明的另一目的在于：提供一种新型焦炉高强漂珠隔热砖的制备方法，包括以下步骤：
(1)按比例称取白石墨、氧化铝粉、粘土、莫来石粉、氧化锆粉、漂珠和木屑，混合均匀，加入水中，再加入粘结剂和减水剂，搅拌均匀，形成泥料；
(2)将所述泥料采用双面加压，缓慢加压之后成型；
(3)成型后进行干燥；
(4)将干燥后的砖坯在窑炉中高温烧制；
(5)拣选合格品，包装，即得。
作为一种改进，步骤(1)中，所述搅拌均匀条件为：以500-600r/min的转速搅拌15-20min
作为一种改进，步骤(3)中，所述干燥分为两个阶段，第一阶段为低温干燥，干燥温度为25-35℃，干燥18-28h；第二阶段为高温干燥，干燥温度为100-120℃，干燥时间20-24h，干燥后砖坯水分质量含量控制在3-5％。
作为一种改进，步骤(4)中，所述高温烧制条件为：于1200-1400℃下保温4-7h。
白石墨具有良好的电绝缘性、导热性、抗腐蚀性和良好的润滑性，化学稳定性较好，常温下不与水、酸、碱反应。
粘土被用作高级耐火材料，其气孔率高、容重小、保温、隔热、不燃、隔音、耐腐蚀，高温蠕变率低，耐压强度高，抗高温能力强。
漂珠是以热电厂粉煤灰中浮选出来的硅酸铝质玻璃空心球，它体轻，壁薄，中空，表面光滑，耐高温，隔热性能好，耐火度≥1610℃，保温绝缘性好，还具有阻燃性，是优良的保温耐火材料。
莫来石粉是铝硅酸盐在高温下生成的矿物，是一种优质的耐火原料，具有耐高温、强度高、导热系数小、节能效果显著等特点。
氧化锆粉化学性质不活泼，且具有高熔点、高电阻率、和低热膨胀系数的性质，使它成为重要的耐高温材料，氧化锆纤维能够在1500℃以上超高温氧化气氛下长期使用，最高使用温度高达2200℃，甚至到2500℃仍可保持完整的纤维形状，并且高温化学性质稳定、耐腐蚀、抗氧化、抗热震、不挥发、无污染。
由于采用上述技术方案，本发明的有益效果是：
本发明提供的新型焦炉高强漂珠隔热砖，大量利用漂珠等副产品，辅以白石墨、粘土、木屑、结合剂及减水剂等，使制得的隔热砖不仅机械强度高，热导率低，工作温度低，保温隔热、防火性能好，性能稳定强度高，无裂纹和崩失现象，还具有优异的抗热冲击性和抗热震稳定性，且工艺简单，生产成本低，可节能15-40％，达到节能和隔热的双重作用，具有较好的应用前景。
本发明提供的新型焦炉高强漂珠隔热砖用于水泥回转窑，窑体温度可降低100℃，用于机械工业热处理电阻炉，可节电30％，还可用于玻璃熔窑、倒焰窑或隧道窑，也可达到节能的目的，用于箱式电阻炉，综合节电率达54％。
