Refractory fiber cone is also called ceramic fiber tap out cone. The furnace tap out cone is mainly used for controlling the liquid metal flow. AdTech refractory tap out cone adopts high-aluminum fiber, forms by the vacuum suction automatic equipment molding process. Each cone has a flat surface. More importantly, it has the features of appropriate hardness and toughness, not fragile, not peeling. Ceramic fiber tap out cone is suitable for mechanical or manual plugging and removal operations. AdTech ceramic fiber tap out cones are used in aluminum furnaces, fixed furnaces and other aluminum outlets. It makes the casting process of aluminum alloys more convenient, safe, and reliable.
