Casting Nozzle Gasket -sales@aluminiumceramicfiber.com

The casting nozzle gasket is a key component of the aluminum strip continuous casting machine. It directly affects the quality of the strip and the yield rate of the production. Alumina ceramic gasket is made of high purity fiber material, it is the casting parts of the ceramic fiber caster tip.

Compared with the ceramic fiber surface of the feed nozzle, the tightly woven glass fiber fabric on the casting nozzle gasket surface is smoother and less aggressive or abrasive. The fabric on the cushion produces much fewer roll scratches than the material of the feed nozzle. The fiber direction of the feed head is random, and the protruding ends are easy to wear on the surface of the caster roller. Compared with the alumina ceramic fiber commonly used to make feed heads, the silica of glass fiber is smoother and less abrasive. The fibers also tend to be closer to the roll tangent, thereby minimizing the end of the abrasive fiber against the roll surface.

The ceramic fiber material layer includes a paper-like material including a high-temperature resistant mineral component that expands when heated. Alumina ceramic gasket is made of high purity fiber material, it is the casting parts of the ceramic fiber caster tip.

When fixed along the edge of the feed nozzle, the casting nozzle gasket made of this material is approximately flat. When the feed head is used for the first time, when the aluminum water is heated, the gasket material will expand, and the outer surface of each casting nozzle gasket will be joined with the surface of the adjacent roller. The surface of the pad conforms to the curvature of the roll and forms a tight “seal” with the roll. The downstream portion allows the cushion to be tapered according to the shape of the continuous casting roll and the downstream edge of the feed nozzle member.

The casting nozzle gasket provides a smoother and less corrosive surface on the roll, thereby minimizing scratches. The gasket material also reduces the overall deflection of the feed nozzle, thus further reducing the possibility of the feed nozzle scraping the pair of casters.
