Filtering method for molten aluminum is based on the principle that the iron-rich phase impurities in the aluminum alloy melt are segregated at a lower temperature and a longer holding time, and mechanical filtration is used to remove the aggregated iron-rich phase materials. The filtering iron removal method is generally carried out during the melt […]

Degassing technology is one of the main components of quality assurance in foundry industry. The quality of cast material depends largely on the number of defects. One of the main defects in near net shape casting is porosity. When melting aluminum scrap, the process of Degassing Technology is very important to produce high quality aluminum […]

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 […]

Molten Aluminum Casting process is to add a certain proportion of electrolytic aluminum liquid and solid charge (remelted aluminum ingots, process waste, and various aluminum-based master alloys) to the melting furnace for smelting. While the electrolytic aluminum liquid is transferred into the melting furnace, various non-metallic inclusions and a large amount of alkali metals in […]

Alumina foam ceramic filter plate produced by our company can effectively remove the fineness of aluminum water to reach the inclusion of micron grade, make aluminum water into stable laminar flow, and facilitate filling.

Tubular filter device was first proposed in the United States in 1960, and later developed and applied by Japan. In Japan and South Korea, tubular filter devices are mainly used as the standard configuration for producing double zero aluminum foil. The tubular filter device is a filter tube made of high-quality lead oxide sintered with […]

In order to optimize the process of aluminum melt filtration technology, a reasonable process configuration is very important. The harm of metallurgical defects in aluminum to processing deformation production and final mechanical properties of products cannot be ignored. To improve the quality of can materials, aircraft materials, etc., it is necessary to pay attention to […]

Aluminum alloy melt alkali metal removal technology can be divided into three types: alkali removal technology before furnace, furnace alkali removal technology, and after furnace alkali removal technology. In the production, you can select a variety or a combination of alkali removal technologies according to the alloy varieties produced to ensure the control of the […]

Alkali metals in aluminum melt mainly include elements Na, Li, K. Among the alkali metal elements, lithium can be used as a strengthening element for aluminum alloys. Its function is to reduce the density of aluminum alloys and improve the elastic modulus of aluminum alloys. In other cases, the alkali metal elements are in the […]

Impurities in aluminum alloy melt contain more or less gas, various non-metallic inclusions, and other harmful metals. The presence of these impurities will directly affect the quality of aluminum alloy, causing ingots such as porosity, pores, slag inclusions, etc. Defects in turn have adverse effects on the mechanical properties, processing properties, corrosion resistance, surface treatment […]
