| 摘 要： | 烧成铝碳质滑板是连铸控流系统的关键功能材料之一,在使用过程中需要承受钢水和渣液的冲刷、快速和反复的热冲击,以及潜在的氧化风险,因此对材料的力学性能、热震稳定性和抗氧化性提出了严苛的要求。近年来,为了持续提高烧成铝碳质材料的上述性能,延长其使用寿命,针对材料结构和组成的优化进行了不断研究,主要包括从金属铝、单质硅等主要添加剂原位形成陶瓷相增强,发展到纳米碳源协同原位陶瓷相增强增韧,以及近期的层状化合物协同纳米碳及原位陶瓷相强韧化和抗氧化。

| Abstract: | Fired alumina carbon sliding plate is one of the key functional materials of continuous casting flow control system. In the process, the materials suffer from the scouring of molten steel and slag, rapid and repeated thermal shock, and potential oxidation risk. Therefore, strict requirements are put forward for the mechanical properties, thermal shock stability, and oxidation resistance of materials. In recent years, in order to improve the above properties of fired alumina carbon materials and prolong their service life, the structure and composition of materials were continuously optimized. The main research directions included the reinforcement of in-situ ceramic phase formed by additives (such as aluminum and silicon), the synergistic strengthen and toughen of nanocarbon with in-situ ceramic phase, and the synergistic effects of layered compounds with nanocarbon and in-situ ceramic phase for strengthening, toughening and oxidation resistance. |
