Made of high-alumina fibers, the original manual production process has been improved to a vacuum suction automatic equipment forming process, featuring high production efficiency, high quality stability, and a finished product rate of 99%. It has the characteristics of uniform mass distribution, higher hardness than ordinary tap out cones, tight blocking, no aluminum adhesion and no slag formation, and is used for controlling and intercepting the flow of metal liquid in boxes and kilns.
1. Formed by vacuum suction of high-alumina fibers, with no aluminum adhesion and no slag falling off;
2. Uniform mass distribution, good elasticity, tight blocking, and stable flow control;
3. High hardness and long service life.
