Aluminum Liquid Purification is important, because the electrolytic aluminum solution contains a large number of non-metallic inclusions and carbides, nitrides, and sulfides. When the electrolytic aluminum liquid directly enters the melting pool of the smelting furnace, it is easy to adhere to the refractory lining of the smelting furnace, and is closely integrated with the lining material over time. Due to the high temperature in the furnace chamber, manual or mechanical cleaning is usually used. It is difficult to avoid mechanical damage to the furnace lining material by mechanically cleaning the furnace in a high-temperature environment, which will adversely affect the service life of the furnace lining material. On the other hand, since the electrolytic aluminum liquid is a very “dirty” melt, it is difficult to smelt a clean aluminum alloy melt with a very “dirty” charge, and it is difficult to produce high-quality aluminum alloy casting products.
Aluminum Liquid Purification
In summary, in view of the influence of inclusions and alkali metal elements in the electrolytic aluminum liquid on the casting performance, processing properties, mechanical properties of the aluminum alloy and the life of the refractory lining of the melting furnace, the pretreatment of the electrolytic aluminum liquid before entering the furnace is It is necessary to reduce the inclusions and alkali metal content in the electrolytic aluminum liquid.
Aluminum liquid purification includes flux refining in the furnace, degassing and filtering outside the furnace. AdTech offers refining flux, online degassing unit, CFF filtering device for aluminum liquid purification. AdTech Metallurgical Materials Co., Ltd.’s products have a very wide range of applications, which are mainly used for casting alloy in civilian areas such like electronics products, furniture, solar equipment, construction, and industrial areas such as autos, high-speed rails, also covering aviation and military fields. They are widely used in metallurgical and casting industry of nonferrous metals, for example, steel, copper, magnesium, etc.
