It has also been proposed that ceramic foam filter can be used as a filter medium because it provides a very small tortuous channel that can trap and retain small suspended particles.<\/p>\n<p>The slag removal outside the furnace is mainly done through the ceramic foam filters for molten metal foundry, which has a multi-layer network and multi-dimensional through holes, and the holes are connected. When filtering, the molten aluminum carries inclusions and flows along the tortuous channels and pores. When it contacts the foamed framework of the filter plate, it is directly blocked, adsorbed, deposited, etc., when the melt flows in the pores, the filter plate channel is curved, The melt flowing through the channel changes the flow direction, and the inclusions collide with the hole wall anvil and firmly adhere to the hole wall.<\/p>\n<p>The main advantage of the <a href=\"http:\/\/www.alalloycasting.com\/ar\/cff-filtering-system\/\">ceramic foam filter system<\/a> is that the slag inclusions generated during the transfer process outside the furnace are effectively eradicated through the filter plate, and the micron-sized inclusions in the aluminum liquid that conventional technology cannot do. At the same time, because the filter plate filters out the fine inclusions and reduces the effective number of crystal nuclei in the molten aluminum, the molten aluminum nucleates and grows under the larger supercooled parts, which shortens the solidification time and refines the structure.<\/p>\n<p>Reduce the hydrogen content in molten aluminum. Hydrogen atoms can be adsorbed on some oxidized inclusions, and the oxidized inclusions can become the core of bubble growth, so the inclusions are filtered out and the gas on them is also removed. Through adsorption, the content of harmful elements (sodium, potassium) in molten aluminum can be removed. According to different customer requirements or on-site environments, selecting a filter plate suitable for ensuring product quality can effectively control slag inclusion.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ceramic foam filters for molten metal foundry are used as a means of separating finely divided solid impurities suspended in the melt.
