Description

一种耐火材料用a-氧化铝粉体及其制备方法
技术领域
本发明涉及耐火材料技术领域，具体涉及一种耐火材料用a-氧化铝粉体及其制备方法。
背景技术
a-氧化铝，具有耐高温的惰性，耐热性强，硬度高，可广泛应用于各种塑料、橡胶、陶瓷、耐火材料等产品的补强增韧，特别是提高陶瓷的致密性、冷热疲劳性、断裂韧性、抗蠕变性能和耐磨性能尤为显著。
现有浇注耐火材料用a-氧化铝粉体，先将a-氧化铝粉体配制成砂浆用于炼钢包和料道的冷态和热态浇注修补，砂浆的流动性和固化时间很不稳定，影响炼钢包和料道的冷态和热态修补的补强效果，增加了施工难度。对炼钢包和料道的冷态和热态修补后的使用寿命有一定的影响；因此，提供一种效果稳定、修补方便、使用寿命长的耐火材料用a-氧化铝粉体及其制备方法是非常有必要的。
发明内容
本发明的目的是为了克服现有技术的不足，而提供一种效果稳定、修补方便、使用寿命长的耐火材料用a-氧化铝粉体及其制备方法。
本发明的目的是这样实现的：一种耐火材料用a-氧化铝粉体，所述的a-氧化铝粉体是由以下重量配比制成：工业一级氧化铝90%-98%，工业一级氢氧化铝1%-9%，硼酸0.1%-1%，特殊矿化剂0.1%-1%。
所述硼酸为除钠剂。
特殊矿化剂为转相矿化剂，转相矿化剂包括氯化铵和氟化钙，其中氯化铵和氟化钙的重量比为9:1。
耐火材料用a-氧化铝粉体的制备方法，所述方法包括以下步骤：
步骤1）：原料称重，各原料按照上述重量配比称取原料；
步骤2）：搅拌混合，将称重后的原料依次加入到搅拌装置中，进行混合搅拌；
步骤3）：煅烧，将上述混合搅拌后的原料放置到煅烧炉中，在1450℃-1480℃条件下煅烧保温60-90分钟，冷却至常温；
步骤4）：研磨，将步骤3）制得的a-氧化铝在球磨机中研磨，粒径控制在D50为3-4微米微粉；
步骤5）：分级，将步骤4）制得的微粉在分级机中分级，剔除粒径大于20微米的微粉粒子；
步骤6）：表面处理，将步骤5）制得的微粉在高速搅拌机中加入1~3‰聚羧酸减水剂进行表面处理；
步骤7）：搅拌混合，将步骤6）制得的微粉搅拌混合均匀。
本发明的有益效果：本发明添加的a-氧化铝粉体，开发的生产技术，即以工业氧化铝和氢氧化铝为原料，通过添加特殊矿化剂，经混合、煅烧、研磨、分级、表面处理等工艺制成的a-氧化铝粉体，将按照此方法制成的a-氧化铝粉体替代原砂浆组份的a-氧化铝粉体3-9%，使得砂浆的流动性和固化时间稳定可控，从而增加了炼钢包和料道的冷态和热态修补的补强效果和补强效果的稳定性，改善了施工难度。使炼钢包和料道的冷态和热态修补后的预期使用寿命稳定；本发明具有一种效果稳定、修补方便、使用寿命长的优点。
附图说明
图1是本发明耐火材料用a-氧化铝粉体及其制备方法制备流程图。
具体实施方式
下面结合附图对本发明做进一步的说明。
实施例1
在耐火材料使用过程中，对炼钢包和料道的冷态和热态修补后的使用寿命影响，砂浆的流动性和固化时间稳定至关重要。
对于一种耐火材料用a-氧化铝粉体来说，砂浆的流动性和固化时间稳定验证好坏与否主要通过胶砂的流动检测来验证，即在施工修补时间内，流动性指标变化小且具有满足施工流动的最低要求，说明加有一种耐火材料用a-氧化铝粉体的胶砂流动性和固化时间稳定性更好。
实验结果：以本发明制备的a-氧化铝粉体，替代原砂浆组份的a-氧化铝粉体3-10%；
1、砂浆流动性实验方法：
①将原料导入混料袋中预混合3分钟；
②将混合好的干料倒入水泥胶砂搅拌机中，干料混合1-5min后加入水，再混合3-5min；
③混均匀后检验砂浆料随时间变化的流动性（0min，15min，30min，45min和60min），流动性检测方法按GB/T2419-2005标准。
2、以本发明制备的a-氧化铝粉体，替代原砂浆组份的a-氧化铝粉体实验，实验数据如下表：
上表为根据添加本发明制备的a-氧化铝粉体的不同情况组成的四中砂浆，其中第一种原砂浆为不添加本发明制备的a-氧化铝粉体，第二种3%替代砂浆为用3%的本发明制备的a-氧化铝粉体代替3%的325目粉体，其余成分不变；以此类推分别制备第三种6%替代砂浆和第四种9%替代砂浆。
3、分别针对上述四种砂浆进行流动性检测结果：
根据上表得出实验结果，在添加3%的本发明制备的a-氧化铝粉体作为替代砂浆时，0min是其流动性略低于原砂浆，但当30min后其流动性高于原砂浆，且可放置的时间明显增加，在60min时达到合格标准值的最低标准；在添加6%和9%的本发明制备的a-氧化铝粉体作为替代砂浆时，且流动性明显高于原砂浆的流动想，固化事件明显增长，且符合合格标准值；说明加有本发明制备的一种耐火材料用a-氧化铝粉体的胶砂流动性和固化时间稳定性更好；本发明具有一种效果稳定、修补方便、使用寿命长的优点。
实施例2
一种耐火材料用a-氧化铝粉体，所述的a-氧化铝粉体是由以下重量配比制成：工业一级氧化铝90%-98%，工业一级氢氧化铝1%-9%，硼酸0.1%-1%，特殊矿化剂0.1%-1%。
所述硼酸为脱钠剂。
特殊矿化剂为转相矿化剂，转相矿化剂包括氯化铵和氟化钙，其中氯化铵和氟化钙的重量比为9:1。
耐火材料用a-氧化铝粉体的制备方法，所述方法按照如图1所示步骤：
步骤1）：原料称重，各原料按照上述重量配比称取原料；
步骤2）：搅拌混合，将称重后的原料依次加入到搅拌装置中，进行混合搅拌；
步骤3）：煅烧，将上述混合搅拌后的原料放置到煅烧炉中，在1450℃-1480℃条件下煅烧保温60-90分钟，冷却至常温；
步骤4）：研磨，将步骤3）制得的a-氧化铝在球磨机中研磨，粒径控制在D50为3-4微米微粉；
步骤5）：分级，将步骤4）制得的微粉在分级机中分级，剔除粒径大于20微米的微粉粒子；
步骤6）：表面处理，将步骤5）制得的微粉在高速搅拌机中加入1~3‰聚羧酸减水剂进行表面处理；
步骤7）：搅拌混合，将步骤6）制得的微粉搅拌混合均匀。
本发明添加的a-氧化铝粉体，开发的生产技术，即以工业氧化铝和氢氧化铝为原料，通过添加特殊矿化剂，经混料、煅烧、研磨、分级、表面处理等工艺制成的a-氧化铝粉体，将按照此方法制成的a-氧化铝粉体替代原砂浆组份的a-氧化铝粉体3-9%，使得砂浆的流动性和固化时间稳定可控，从而增加了炼钢包和料道的冷态和热态修补的补强效果和补强效果的稳定性，改善了施工难度。
