In the Aluminum Melt Purification methods mainly to remove impurities, the filtration method is generally carried out after degassing and before pouring (such as the filter screen is placed at the gate or runner, etc.), and its impurity removal mechanism is mainly mechanical and physical functions, which has no significant effect on the removal of […]

In the actual production, we need to adopt reasonable Aluminum Degassing Treatment method to improve the purity of aluminum melt and provide high-quality aluminum rods for the subsequent process. In the melting process of aluminum and aluminum alloy, the surface is easy to be oxidized to form Al2O3, and at the same time, it is […]

Typical structure of ceramic filter unit used in some factories. The shell of this kind of ceramic filter is welded with 10 mm thick, lined with aluminum silicate fiber felt, and then laid with a layer of light refractory brick and coated with talcum powder inside. A and B chambers are separated by porous ceramic […]

There are some factors that affect the molten aluminum flux refining effect, includes the flux composition, flux dryness, completeness of flux treatment, and refining process parameters. Molten Aluminum Flux Refining Influence Factors 1) The nature of the salt that makes up the flux. Generally, chloride flux can wet oxides and melt well, and adding fluoride […]

The process and operation of removing gases, inclusions, and harmful elements from the melt to obtain good aluminum liquid is called refining. It is also called purification. There are many refining methods for aluminum alloys, which can be divided into two basic types: adsorption refining and non-adsorption refining. According to the refining position, it can […]

The purpose of refining and slagging of aluminum alloy is to remove gas and impurities in liquid aluminum. In the existing die casting industry, the combination of physical adsorption and chemical reaction is often used. When the die-casting aluminum alloy is melted, the way of rapid submergence is adopted, that is to keep a certain […]

Refining for aluminum alloy flat ingot: (1) The proportioning ratio of electrolytic aluminum liquid should be controlled. The temperature of molten aluminum in the electrolytic cell is about 930 ℃. After being sucked out by vacuum ladle and transported to the foundry workshop, the temperature of molten aluminum remains at 860 ℃ ~ 900 ℃ […]

“Degassing” generally refers to the removal of gases from alloys, and “refining” refers to the removal of inclusions in alloys. The purpose of aluminum melt degassing and refining is to remove or reduce oxide inclusions and gases as far as possible, so as to improve the degree of metal purification. Therefore, aluminum melt degassing and […]

After the aluminum alloy is completely smelted, there are many scum on the surface, mainly Al2O3 and other oxides. These small slag inclusions are heavier than molten aluminum, but have a lighter specific gravity after agglomeration. They float on the surface and need the Refining Process for Aluminum Alloy. The amount of slag cleaning agent […]

For non-metallic inclusions, the use of gas refining methods can be effectively removed. For the more demanding materials, the CFF filtration method is best way for impurities removal in aluminum alloy by mechanical filtration through the molten aluminum layer. For metal impurities, the general treatment method is to turn harmful factors into favorable factors. That […]
