Description
技术领域
本发明涉及压注料技术领域，特别涉及一种刚玉质压注料。
背景技术
耐火压注料利用挤压施工的膏状或浆体不定形耐火材料，又称压入料，它是由耐火骨料、粉料、结合剂和外加剂组成的，使用时加水或液态结合剂调和耐火压注料分类，按压注料材质分有：高铝质、氧化铝(刚玉)质、铝镁质、铝碳质、镁碳质耐火压注料等，高炉出铁口用炮泥是一种常用的压入料，每次高炉出铁后，就采用泥炮讲炮泥挤入出铁口，一遍堵住出铁口，防止铁水流出，渣口也用类似的泥料封堵，因此高炉用炮泥应有足够的耐火度，耐火压注料主要应用于高炉炉身、回转窑窑衬热点部位、RH上升管及顶底复吹STB转炉小炉底、转炉出钢口等，高炉炉身压注修补多采用硅酸铝质和高铝质耐火压注料，水泥回转窑使用高铝质耐火压注料，STB转炉及转炉出钢口使用镁碳质耐火压注料，RH浸渍管使用刚玉质或铝镁质耐火压注料。但是现有的刚玉质压注料存在存在一定的弊端，刚玉质压注料的粘度较低，凝固时间较长，不方便后续工作。

S3中研磨时间为30分钟；S5中性能测试温度为110℃，测试时间为24小时。
需要说明的是，本发明为一种刚玉质压注料，在使用时，将压入料的原料按照要求制备好，然后将振动磨进行开启，其中原料包括氧化铝90-95份，氧化硅42-46份，氧化镁5-8份，石墨20-22份，白刚玉8-12份，硼酸8-12份，氧化钙2-6份，95％的硅微粉1-2份，三聚磷酸钠0.5-1份，六偏磷酸钠0.5-1份进行制备，将振动磨调试到合适的速度和时间，研磨时间为30分钟，将准备好的原料放入到振动磨中研磨，使得原料氧化铝、氧化硅、氧化镁和石墨充分混合，再将原料白刚玉、硼酸、氧化钙、95％的硅微粉、三聚磷酸钠、六偏磷酸钠放入混合，此时完成制备，将准备好的刚玉质压注料进行性能测试，性能测试温度为110℃，测试时间为24小时，设有氧化硅42-46份，氧化镁5-8份，石墨20-22份，通过加入的氧化镁制成氧化镁形成镁铝尖晶石，因此具有良好可塑性和黏结性好、容易挤出并填满空袭和裂纹，加入硼酸8-12份，氧化钙2-6份，95％的硅微粉1-2份，三聚磷酸钠0.5-1份，六偏磷酸钠0.5-1份，使得刚玉质压注料烧结性好，强度高，耐侵蚀和抗冲刷性好，具有良好的高温机械性能及抗渣蚀性能，使得刚玉质压注料凝固比较迅速，等待时间较短。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
