Stopper rod head and preparation method thereof
The invention discloses a stopper rod head and a preparation method thereof, wherein the stopper rod head comprises spinel particles with different particle sizes, graphite 199, graphite 899, an additive and a binding agent, and specifically comprises, by weight, 30-40% of white corundum 36#, 10-20% of white corundum 80#, 30-40% of white corundum 325#, 10-20% of graphite 199, 5-10% of graphite 899, 5-10% of an additive, and 10-15% of a binder. According to the invention, spinel is adopted to replace previous corundum to serve as the main material of the stopper rod head, and reacts with the additive to generate forsterite or calcium forsterite to seal part of the gas holes in the material, so that the additive is prevented from permeating into the material, the erosion resistance is improved, and the service life of the stopper rod head is prolonged through the special ratio.
本发明公开了一种塞棒棒头及其制备方法，包括不同粒径的尖晶石颗粒、石墨199、石墨899、添加剂、结合剂，按重量百分比如下：白刚玉3630‑40%、白刚玉8010‑20%、白刚玉32530‑40%、石墨199 10‑20%、石墨899 5‑10%、添加剂5‑10%、结合剂10%‑15%。本发明采用尖晶石来替代以往的刚玉作为塞棒棒头的主要材料，尖晶石与添加剂的反应过中生成镁橄榄石或钙镁橄榄石，封闭材料中的部分气孔，阻止添加剂向材料中的渗透，提高了抗侵蚀性并通过特殊的配比实现延长塞棒棒头使用寿命的效果。
