In order to further control the content and size of inclusions and eliminate the harmful effects of large-particle inclusions, most of the aluminium melt purification technology is used in the melt treatment process of electrolytic aluminum liquid. Through the number of holes per unit area of ​​the filter, the purpose of removing non-metallic inclusions is […]

The quality of molten aluminum flow control in the aluminum alloy casting process is a key factor in determining the quality of the ingot. Especially in the hollow aluminum alloy ingot casting process, the liquid level must be controlled well and not fluctuating high and low. If the liquid level in the crystallizer is too […]

The comprehensive purification of refining agent and CFF filtration is the aluminum melt purification technology commonly used by the majority of aluminum processing enterprises. This process comprehensively integrates the degassing and slag removal advantages of FILD, MINT, SNIF, and other purification methods, with low purification costs and convenient production operation has resulted in excellent casting […]

The aluminum melt filtration treatment after the hydrogen removal is the most effective and reliable means to remove non-metallic inclusions. There are many kinds of filtering methods, the most effective ones are corundum filter tube and foam ceramic filter plate. The corundum tube filter has high filtration efficiency, but it is expensive and inconvenient to […]

The hydrogen removal process is the gas purification process. Artificially add inert gases (Ar, N2, etc.) or active gases that are insoluble in the aluminum melt (Cl2, C2Cl4, etc.) into the aluminum melt, so that the hydrogen melted in the aluminum melt is absorbed by these gas bubbles. The bubbles float upward and escape the […]

The slagging and degassing methods in the smelting process of aluminum and aluminum alloys can generally be divided into flux covering and inert gas protection methods; chemical reaction and adsorption methods, namely flux and gas refining methods; non-adsorption methods, mainly including vacuum and CFF filtration methods. In addition, according to different refining purification media, it […]

The online refining methods outside the furnace include the MINT method, SNIF method, ALPUR method, FILD method, and so on. Most of these online refining purification methods closely combine degassing and filtration purification. The SNIF method and the ALPUR method use a rotating rotor to blow gas. Make small bubbles uniformly dispersed in the melt. […]

In order to remove the slag and gas in the melt, in addition to the use of flux refining, rotating rotor degassing, and CFF filtration equipment for purification, the control of the smelting process cannot be ignored. Control of Aluminum Smelting Process First, choose dry raw materials (including refining agents) that contain less slag. All […]

Metal refining treatment can remove or minimize the gas and oxide inclusions in the regenerated aluminum alloy melt, so as to improve the degree of purification of the melt. The requirements for the purity of recycled aluminum alloy melts are different due to different varieties and uses. It is usually required that the hydrogen content […]

The aluminum fluxes refining method has a good effect on discharging non-metallic inclusions. The degree of purification by the flux to remove non-metallic inclusions in the melt is not only related to the physical and chemical properties of the flux, but also depends to a large extent on the refining process conditions, such as the […]
