Description

一种氧化镁微粉增强铝锆碳质滑板及其制备方法
技术领域
本发明属于连铸用耐火材料技术领域，主要涉及了一种氧化镁微粉增强铝锆碳质滑板及其制备方法。
背景技术
在传统的氧化物耐火材料中添加一定量的碳素，可显著改善耐火材料抗渣性和抗热震性两个关键性能，同时有效提升耐火材料的使用寿命。含碳耐火材料的开发和应用大大提升了冶金行业，尤其使钢铁冶金的发展。但是，含碳耐火材料也有自身不可克服的缺陷。一个是抗氧化性差。虽然碳与熔渣相容性差，但却非常容易被氧化。一旦氧化，就会形成气孔，造成抗渣性下降。其次是对钢水的增碳影响。在精炼和连铸阶段，需要严格控制钢液中夹杂物的含量，否则会严重影响出钢品质。尤其对低碳钢和超低碳钢这种特种钢材，高碳耐火材料的增碳行为会严重影响其品质。
连铸工艺是高炉炼铁和转炉（电炉）炼钢之后的重要工序。由钢包、中间包、结晶器、二冷段等构成。装置之间由水口（长水口、浸入式水口）连接，并传输钢水。用滑板砖来控制钢水流速。因为滑板砖需要根据工况来滑动控制钢水流速，所以也需要较高的耐磨性能。通常用氧化锆来增强滑板材料的耐磨性和抗热震性。因为氧化锆具有低膨胀性和优异的耐磨性。但即使如此，更高性能的滑板材料仍然是被需要的。
发明内容
本发明在现有技术的基础上，提出了一种工艺相对简单、性能更好的铝锆碳质滑板材料，并公开了一种氧化镁微粉增强铝锆碳质滑板及其制备方法。。用该法制备的滑板材料，因为高温原位反应形成了镁铝尖晶石，显气孔率、力学性能、抗热震性，及耐磨性都得到了一定程度的增强。
为了实现上述目的，本发明采用了如下的技术方案：
一种氧化镁微粉增强铝锆碳质滑板及其制备方法，其特征在于，原料包括电熔刚玉、锆莫来石、铝粉、碳素、结合剂、氧化镁微粉。
所述的电熔刚玉纯度≥99.5%，粒度3~1 mm（25%~35%），≤1 mm（15%~20%）两种。
所述的锆莫来石纯度≥99.5%，粒度1~0.088 mm（15%~20%），≤0.088 mm（15%~20%）两种。
所述的铝粉纯度≥99.5%，粒度≤0.044 mm（1%~3%）。
所述的碳素为高纯石墨纯度≥98.5%，粒度≤0.044 mm（8%~12%）。
所述的结合剂为液态酚醛树脂，工业用纯度（2%~5%）。
所述的氧化镁微粉纯度≥99.5%，粒度≤10 μm（0.5%~2.5%），在原料总质量上外加。
一种氧化镁微粉增强铝锆碳质滑板及其制备方法，其特征在于，具体步骤包括混料、成型、热处理。
所述的压制成型仪器为液压式压力机，采用单次保压成型。压力250~300 MPa，保压1~3 min。
所述的热处理温度为1500~1700 ℃，保温时间5~8 h。
与现有技术相比，本发明的有益效果在于：
本发明通过引入氧化镁微粉，可以提高铝锆碳滑板材料的气孔率、强度、抗热震性和抗渣性能。增强机理是原位增强。因为氧化镁微粉具有高活性，可以和氧化铝细粉反应形成镁铝尖晶石（MgO+Al2O3=MgAl2O4）。尖晶石有着出色的强度和抗热震性，同时因为是原位化学合成，可以对基体形成陶瓷结合，提升材料整体的强度。另外，此反应约由8%的体积膨胀，可使材料内部的气孔细化（因碳氧化形成的气孔）。避免因气孔增大造成渣渗透严重，甚至损毁。其次，原位形成的尖晶石还能吸收一部分渣中的锰和铁，形成固溶体，增大渣的粘度。这对浇铸锰脱氧钢非常有利。
