Description
技术领域
本发明涉及耐火材料技术领域，具体地指一种轻质高强度耐火浇注料。
背景技术
薄板坯连铸连轧隧道式加热炉高温水冷炉辊担负着炉内板坯支撑与行进驱动任务，长时间处于温度1100～1300℃高温环境中工作，炉辊通过外壁布置的四道耐热金属辊环与板坯直接接触，起到支撑与驱动作用，为了保障炉辊的高温强度，通常在金属辊环之间采用耐火隔热保护层，并在炉辊内部通水进行冷却，起到保护炉辊、降低水冷热损失、延长使用寿命的作用。由于炉辊数量众多、水冷流量大，导致加热炉水冷热损失较高，特别是炉辊在长时间的高速运转和机械振动作用下，炉辊耐火隔热保护层容易出现开裂破损和脱落，从而影响炉辊使用寿命和隔热性能。
炉辊耐火隔热保护层主要有耐火浇注料和耐火纤维材料，其中单一的耐火纤维材料由于高温性能劣化、使用寿命较短，在实际的应用中较为少见，目前应用最多的是耐火浇注料隔热保护层。例如授权公开号CN100408515C的中国专利公开了一种用于辊底炉炉辊的耐火浇注料，该炉辊浇注料是由以下配比的组分制成，计量单位为重量百分比：电熔莫来石(粒度≤3mm)：20～45％，焦宝石(粒度l～5mm)：0～30％，莫来石(粒度200目)：10～20％，堇青石(粒度≤5mm)：10～25％，蓝晶石(粒度180目)：5～10％，氧化硅微粉(粒度≤5μm)：2～3％，氧化铝微粉(粒度≤5μm)：5～8％，高铝水泥：4～5％，不锈钢纤维：2～4％，防爆纤维：0.1～0.15％，三聚磷酸钠：0.15～0.3％，水：7.5～10％。该专利一定程度上改善了浇注料层开裂与脱落的效果，提高了炉辊使用寿命，但仍存在导热系数较高、隔热性能差的不足。
公开号CN101792294A的中国专利申请公开了一种轻质隔热耐火浇注料，它包括以下重量百分比的组分：化学改性轻质骨料：40～60％；电熔莫来石(0～1mm)：10～20％；蓝晶石粉(粒度180目)：5～10％；一级高铝矾土熟料粉(粒度180目)：5～10％；二氧化硅微粉(粒度≤5μm)：3～8％；α-Al2O3微粉(粒度≤5μm)：3～8％；高铝水泥：5～10％；含锆高铝耐火纤维：0.5～10％；耐热钢纤维：1.5～4％；三聚氰胺：0.1～1％；有机防爆纤维：0.05～0.10％。该专利申请通过采用轻质骨料降低了浇注料的导热系数，并通过对轻质骨料进行化学改进，显著提高了轻质浇注料的力学性能和使用寿命，但是与上一个专利类似，由于采用了钢纤维作为增强增韧的方式，在高温使用过程中，钢纤维容易发生高温氧化膨胀与脆化失效，并通过氧化产物与耐火浇注料的高温反应劣化浇注料的高温使用性能。
为了克服上述缺陷，授权公开号CN102161593B的中国专利公开了一种CSP炉辊隔热衬用轻质耐火浇注料，采用耐火纤维代替钢纤维起到增强增韧的作用，其组分按重量百分数计为：轻质莫来石骨料：40～50％；焦宝石(粒度0.1～1mm)：5～8％；蓝晶石粉(粒度60～120目)：5～7％；一级高铝矾土熟料粉(粒度≤180目)：6～9％；硅微粉：7～9％；α-Al2O3微粉：5～8％；高铝水泥：10～18％；耐火纤维：1～4％；锂辉石(粒度160～200目)：1～1.5％；六偏磷酸钠：0.05～0.154％；有机减水剂：0.05～0.15％：有机硅烷偶联剂0.04～0.07％；消泡剂：0.03～0.06％。该专利相对授权公开号CN100408515C中国专利中的重质浇注料而言，具有容重轻、力学性能好、热震稳定性能优良的特点，但是由于轻质莫来石骨料在运输、搬运的过程中容易发生破碎，骨料性能的劣化不仅导致耗损量的增加，更会导致浇注料的力学性能的波动，此外其隔热性能还有待进一步提高。
发明内容

作为上述技术方案的改进，所述轻质高强微孔矾土骨料是颗粒级配的，具体包括：重量百分比15～20％的5mm≤粒度<3mm的轻质高强微孔矾土骨料，重量百分比8～15％的3mm≤粒度<1mm的轻质高强微孔矾土骨料。这两种颗粒级配的轻质高强微孔矾土骨料的重量百分之和为25～35％，就是本发明原料中所需的轻质高强微孔矾土骨料。
作为上述技术方案的改进，所述氧化铝空心球是颗粒级配的，具体包括：重量百分比13～18％的3mm≤粒度<1mm的氧化铝空心球，重量百分比8～20％的1mm≤粒度<0.2mm的氧化铝空心球。这两种颗粒级配的氧化铝空心球的重量百分之和为25～35％，就是本发明原料中所需的氧化铝空心球。

作为上述技术方案的改进，所述复合减水剂为FDN高效减水剂、木制素磺酸钙和三聚磷酸钠的混合物，其中FDN高效减水剂占复合减水剂总质量的60～70％，木制素磺酸钙占复合减水剂总质量的10～15％，三聚磷酸钠占复合减水剂总质量的15～25％。
作为上述技术方案的改进，所述水性硅聚醚消泡剂为市售RK-720F硅聚醚消泡剂。
与现有技术相比，本发明的有益效果在于：
通过不同骨料级配的轻质高强微孔矾土骨料、氧化铝空心球和漂珠的组合使用，利用三种骨料自身存在的微孔和球型封闭气孔的微观结构，提高浇注料的高温性能、隔热性能和抗热震稳定性，达到提高炉辊隔热性能，减少冷却水带走的热损失，同时降低体积密度，减少炉辊的重量与转动动力消耗的目的。
通过1～5mm轻质高强微孔矾土骨料与0.2～3mm氧化铝空心球的配合使用，相对纯氧化铝空心球浇注料而言，减少了氧化铝空心球的用量，降低了生产成本，同时通过0.2～1mm氧化铝空心球的使用，弥补了0～1mm轻质高强微孔矾土骨料性能劣化的不足，避免了浇注料中0～1mm骨料级配的缺失，提高了浇注料的力学强度和热震稳定性。
通过漂珠的加入，不仅增加了浇注料中微米级封闭球型气孔的数量，进一步降低导热系数，提高隔热性能，还改善了浇注料的流动性，同时由于水冷炉辊隔热衬冷面与通冷却水的钢管接触，温度30～50℃，另一侧热面与高温烟气接触，温度1100～1300℃，浇注料靠高温烟气侧处于温度>1100℃工作区域的漂珠由于低熔点杂质的存在会部分发生液相反应，起到烧结促进作用，提高浇注料的高温强度。
通过80～120目蓝晶石粉的加入，利用蓝晶石1100℃分解膨胀生成莫来石和石英的特点，弥补了轻质浇注料高温烧结收缩的不足，提高了浇注料的高温体积稳定性，避免了高温收缩引起的开裂破损。
通过熟铝矾土细粉的加入，减少矾土水泥和水的用量，弱化了水泥结合体系中水合铝酸钙在900～1200℃范围二次铝酸一钙、二铝酸一钙化导致的中温强度下降的影响。
通过矾土水泥、硅微粉和α-Al2O3微粉作为复合结合剂，引入水合结合和凝聚结合两种凝结硬化机理，提高浇注料的低温强度，同时高温下会形成针状莫来石，进一步提高了中温和高温强度。
通过耐火纤维的加入，改善了浇注料的热震稳定性，提高了浇注料的隔热性能；特别是采用冶金炉窑用后废弃含锆耐火纤维或硅酸铝耐火纤维进行制备，不仅降低了浇注料成本，还解决了用后耐火纤维带来的环境问题；通过采用浓度为0.7～0.8g/100mL的聚乙二醇水溶液对耐火纤维表面进行改性处理，改善了耐火纤维的界面结合及其在浇注料中的分散状态，增进了耐火纤维的增强和增韧作用。
通过FDN高效减水剂、木制素磺酸钙和三聚磷酸钠三种减水剂的优化组合，避免了单一减水剂的性能短板，提高了浇注料的施工流动性，降低了浇注料的加水量，达到既具有高减水率又不离析的效果。
通过市售RK-720F硅聚醚消泡剂的加入，遏制了浇注料加水搅拌过程中胶体材料中气泡的形成，避免了耐火粉料在气泡周围的粘接，提高了浇注料的流动性，同时，也遏制了气泡在胶体材料与轻质高强微孔矾土骨料以及氧化铝空心球表面的形成，提高了胶体材料在轻质高强微孔矾土骨料微孔中的渗透深度，扩展了浇注料中骨料与胶体材料间的结合界面，改善了轻质高强微孔矾土骨料和氧化铝空心球的界面结合状况，提高了浇注料的力学性能。
通过上述综合措施，本发明实现了降低轻质浇注料容重、提高力学强度和隔热性能的目的，而且各种原材料均为普通的市售原材料或废弃耐火材料，具有原材料易得、成本低廉的优点。采用本发明浇注料制备的水冷炉辊隔热衬，具有性能稳定、容重轻、力学性能好、隔热性能与抗热震稳定性优良的特点，达到降低炉辊水冷热损失、延长炉辊使用寿命、降低能耗与维护成本的目的。
