The ceramic foam filter for casting can remove these impurities from the molten aluminum during the aluminum casting process. Generally, filtering molten metals, especially aluminum, poses special problems because liquids are very corrosive and it is difficult to find filter media that can withstand liquids. Typically, these Alu casting filters are made of ceramic materials […]

Aluminum refractory launders are usually internally lined channels used to transport molten aluminum. Launder is a good insulator that will not be wetted by molten aluminum and has excellent mechanical strength, including resistance to metal wear and physical damage. Since 2012, our company has begun to research and develop integral launders, degassing devices and plate […]

Rotary degassing of molten aluminum alloys is a widely used commercial process to control the content of hydrogen, alkali metals, and inclusions in the melt before casting. In today’s foundries, we recognize two major issues with molten metal quality: gas content and inclusions. When age-hardening alloys are developed, the presence of pores becomes more problematic […]

Since the ceramic foam filter has excellent resistance to molten aluminum corrosion, it can effectively remove inclusions, reduce residual gas and provide laminar flow in the molten aluminum casting process. Molten aluminum casting filter is suitable for improving the quality of aluminum alloy and other non-ferrous alloy castings. It can improve metallurgical structure and enhance […]

Aluminum is one of the most used materials in casting practice. However, iron is one of the most troublesome impurities in aluminum casting materials. During the solidification of aluminum alloys, iron promotes the formation of mesophases, which may impair the performance of the final product. In the secondary aluminum industry, iron pollution may always be […]

Ceramic foam filters for aluminium can effectively remove large inclusions in molten aluminum, absorb micro inclusions in particles, improve product performance and microstructure, and are widely used in aluminum alloy castings and other production areas. Ceramic foam filters molten aluminium filtration are insoluble in molten aluminum at temperatures of 800°C or lower, and are resistant […]

In 1978, aluminum oxide, kaolin were used to produce ceramic foam filters for filtering metal melt and successfully applied to casting gate systems. In 1984, successfully developed a bubble ceramic filters are used to filter non-ferrous metal liquids. So far, many countries have production technology and supporting production facilities. In the early 1980s, China began […]

The main function of the online degassing system is to remove the hydrogen dissolved in the molten metal, and the secondary function is to remove alkali metals and inclusions. The selection of online degassing equipment is related to the functionality of the final casting product. According to the humidity conditions in the ambient atmosphere, the […]

The non-toxic refining flux is mainly used for the smelting and refining of pure aluminum, aluminum alloy and secondary aluminum to remove hydrogen and surface scum in the aluminum liquid, and can absorb the slag near the surface. The non-toxic refining agent is one of the fluxes necessary for the smelting of aluminum and aluminum […]

The non-toxic refining agent is composed of six components including KCl, NaCl, CaF2, Na2SiF6, Na3AlF6, and C2Cl6. The use of refining agent to smelt aluminum and aluminum alloy has a better degassing and impurity removal effect, which can make the hydrogen content in the aluminum alloy melt lower, and can more effectively reduce the burning […]
