According to the principle of aluminum refining agent purification, the refining agent generates tiny gas bubbles through a chemical reaction in the aluminum melt. When these gas pools float up, hydrogen and non-metallic inclusions are taken out of the surface of the aluminum melt. At the same time, the non-metallic inclusions are wetted by the […]

When high-purity argon is used as the refining gas for molten aluminum alloy refining, the argon should be preheated in advance to improve the refining effect. Using preheated argon for refining can produce high temperature and fine and uniform “hot bubbles”, with a small temperature difference with the melt, which is conducive to the stability […]

To produce high-quality double zero aluminum foil, it is necessary to strictly control the residual hydrogen content in the aluminum foil blank. Aluminum melt purification process can reduce the formed bubbles, and reduce its influence on the processing performance of the aluminum foil. In the current industrial production process, the hydrogen content of aluminum foil […]

The tabletop refractory product is made by placing aluminum-silicon material in a mold, uses molten high-silica 140 material. It is used to distribute molten metal to mold positions in billet casting tables, performs molten metal casting in cooperation with other casting equipment, such as thimbles, transition plates. In the air-slip casting table, close casting is […]

According to the different degassing mechanisms, the molten metal degassing refining method of aluminum alloy melt can be divided into partial pressure difference degassing, compound degassing, electrolytic degassing, etc. The partial pressure difference molten metal degassing refining method is to place the gas-dissolved metal in a vacuum with a small hydrogen partial pressure, or to introduce […]

For many years, foundries have used aluminium casting refining fluxes to reduce alloy waste, control scum formation, and remove impurities in the alloy, otherwise, these impurities will affect the quality. The fluxes for aluminum smelter are usually the mixture of chloride and fluoride salts, minimize the penetration of atmospheric hydrogen and absorb non-metallic inclusions suspended […]

Foundry refining fluxes are based on the molten salt mixture, usually used for the processing of molten aluminum. It is used to passively protect metals from oxidation and remove additive elements as impurities from molten aluminum. Foundries refining flux is mainly used for reducing the content of hydrogen and inclusions. Dissolved hydrogen is one of […]

Filters in the melting and casting workshop can take many forms, aluminum foundry usually uses ceramic foam filters (CFF) as the main molten metal filters. At present, the aluminum industry requires strict metal quality standards to prevent parts failure in key components of automobiles, airplanes, and machinery. Filtration is the last online metal treatment process […]

We supply ceramic foam filters for foundries. Alumina Ceramic Foam Filter is applied to filter molten aluminium and aluminium alloys. White in color alumina foam filter is made from high purity alumina (AI2O3). It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration. Ceramic foam […]

Aluminum Casting Ceramic Filters are increasingly used in the aluminum rod and ingot casting process in the aluminum industry. They are special filters made of materials such as alumina to give them structural stability and ensure thermal shock resistance. Aluminum Casting Ceramic Filters can remove oxides on the aluminum surface to improve casting quality. More […]
