Stopper rod body and preparation method thereof

The invention discloses a stopper rod body and a preparation method thereof, wherein the stopper rod body comprises the following components in percentage by weight: 30-40% of brown fused alumina 36#,10-20% of brown fused alumina 80#, 30-40% of brown fused alumina 180#, 10-20% of graphite 199, 5-10% of graphite 899, 5-10% of an additive and 10-15% of a binding agent. According to the invention, the stopper rod body is prepared through preparation, friction pressure forming and high-temperature sintering, so that the good beta-SiC and alpha-Al2O3 network ceramic combination is formed, the material bonding strength is improved, the high-temperature use performance of the product is enhanced, and the strength and the wear resistance of the material are improved. 本发明公开了一种塞棒本体及其制备方法，本发明提供的配方包括以下重量百分比的组分；棕刚玉3630-40%、棕刚玉8010-20%、棕刚玉18030-40%、石墨199 10-20%、石墨899 5-10%、添加剂5-10%、结合剂10%-15%。本发明经配制、摩压成型、高温烧结工艺制成的塞棒本体，形成了良好的β-SiC和α-Al2O3网络陶瓷结合，提高了材质结合强度，增强了制品高温使用性能，提高了材料的强度和耐磨性。
