Anti-nodulation material, submersed nozzle lining, submersed nozzle and preparation method of submersed nozzle lining
The invention relates to an anti-nodulation material, a submersed nozzle lining, a submersed nozzle and a preparation method of the submersed nozzle lining. According to the mainly adopted technical scheme, the anti-nodulation material is used for preparing a submerged nozzle lining and comprises the following components in percentage by weight: 5-80% of a rare earth oxide, 5-35% of graphite, 1-10% of a phenolic resin, 0-89% of a reinforcing material, and 0-5% of an antioxidant. The anti-nodulation material is used for preparing a submersed nozzle lining for rare earth steel continuous casting. The submersed nozzle comprises a submersed nozzle body and a submersed nozzle lining, wherein the submersed nozzle lining is inlaid on the inner wall of the submersed nozzle body, and the submersed nozzle lining is prepared from the anti-nodulation material. According to the invention, the anti-nodulation material is mainly used for improving the anti-nodulation capacity of the submersed nozzle and ensuring the thermal shock stability, the pressure resistance, the breaking strength, the erosion resistance and the scouring resistance of the submersed nozzle, so that the use requirement that rare earth steel is continuously cast for a long time without being blocked can be met.
本发明是关于一种防结瘤材料、浸入式水口内衬、浸入式水口及其制备方法。主要采用的技术方案为：一种防结瘤材料，用于制备浸入式水口内衬，以重量百分比计，防结瘤材料包括如下组分：稀土氧化物：5‑80％；石墨：5‑35％；酚醛树脂：1‑10％；增强料：0‑89％；抗氧化剂：0‑5％。所述的防结瘤材料用于制备稀土钢连铸用浸入式水口内衬。一种浸入式水口，包括浸入式水口本体和浸入式水口内衬；其中，浸入式水口内衬镶贴在浸入式水口本体的内壁上；其中，浸入式水口内衬由所述的防结瘤材料制备而成。采用本发明主要是用于提高浸入式水口的防结瘤能力，并确保其热震稳定性、耐压和抗折强度、抗侵蚀以及耐冲刷性，从而能满足稀土钢长时连铸而不堵塞的使用需求。
