The baffle extends through the plenum and has a plurality of holes through which the metal reaches the tip. The hole is smaller near the center of the pouring tip and gradually larger toward the edge to ensure that the molten metal is distributed across the entire width of the pouring tip.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-7959\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/12\/Feed-Tip.jpg\" alt=\"Feed Tip\" width=\"400\" height=\"320\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/12\/Feed-Tip.jpg 400w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/12\/Feed-Tip-300x240.jpg 300w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/p>\n<p>The feed tip is assembled from two long hardened ceramic fiber boards, which has good stability and durability. The plates are held together by bolts passing through the upstream spacer between the two plates. The upstream spacers are arranged in a row parallel to the pressurizing chamber. The second row of downstream spacers between the plates keep the upstream portions of the plates parallel to each other.<\/p>\n<p>Each gasket can minimize turbulence in the metal flowing through the tip. It has been found that solid inclusions tend to accumulate behind spacers or other baffles in the tip, and when such insolubles accumulate in sufficient amounts, they may detach and appear in the cast piece. In more severe cases, this accumulation of solids in the tip may cause partial clogging of the tip and the need to shut down the continuous caster due to defective plates. It is also important to minimize the number of spacers in the tip so that there are only enough spacers to maintain the structural integrity of the tip. This reduces the local velocity of the molten metal, thereby reducing turbulence.<\/p>\n<p>There is an ear at each end of the pouring head, which prevents the metal from flowing longitudinally along the rollers until it freezes into the casting plate.<\/p>","protected":false},"excerpt":{"rendered":"<p>The high-speed aluminum casting process is particularly sensitive to any flow interruptions within the casting feed tip and nozzle.
