The utility model provides an anti-oxidation high-performance stopper rod which comprises a stopper rod body and a stopper rod head arranged at the lower end of the stopper rod body, a stopper rod middle hole is formed in the stopper rod body, and an argon blowing-in hole is formed in the upper end of the stopper rod at the top of the stopper rod middle hole. A plurality of argon discharge holes communicated with the stopper rod middle hole and the outside of the stopper rod are uniformly formed in the stopper rod body in the radial direction, the argon discharge holes gradually incline downwards from the axis of the stopper rod to the outer circumference, and the inclination angle is set to be 1-30 degrees. By means of the mode, the situation that the strength of the stopper rod body is reduced due to oxidation caused by falling of glaze can be prevented, and the breakage accident of the stopper rod body is avoided. 本实用新型提出了一种抗氧化高性能塞棒，包括：塞棒本体以及设置于塞棒本体下端的塞棒棒头，在所述塞棒本体内开始有塞棒中孔，在所述塞棒中孔顶部塞棒的上端处设置有氩气吹入孔，在所述塞棒本体沿径向
