The aluminum melt distribution bag is made of non-stick glass fiber fabric and rigid lining cloth. The coated distribution bag generates slight gas and less smoke when in contact with molten aluminum. This product is mainly used to分流 aluminum melt to both ends of the slab, helping determine the temperature distribution around the mold, which influences the microstructure of the solidified aluminum alloy ingot. At the same time, it retains oxides within the bag, reduces turbulence of the aluminum melt, and filters out larger particles (such as large refractory debris of alumina, chlorides, titanium-boron, magnesium oxide, etc.).
