The rotating rotor degassing method can give full play to the hydrogen removal advantages of the bubble floatation method. The key is that the liquid forms turbulent flow under the strong action of the rotor, and the bubbles are broken and uniformly dispersed under the action of the rotor and the turbulent flow. The rotating […]

The aluminium flux purification of molten aluminum is one of the measures to ensure high-quality aluminum alloy products, and it is also the main means to improve the overall quality of aluminum alloys. The refining effect of molten aluminum has an important influence on the formation of pores, shrinkage cavities and inclusions, and directly affects […]

Foam ceramic plate filtering is the last process in the purification treatment of aluminum melt. It is particularly important to choose the second generation of foam ceramic filter plates. It needs to be particularly pointed out that the secondary pollution of the melt that may occur after the aluminum melt leaves the filter box to […]

Choosing the best ceramic foam filter plate is an important task, and the size of the filter plate depends on the flow rate and total amount of the filtered metal. Semi-continuous casting mainly considers the flow of metal, while continuous casting mainly considers the total amount of metal. The size of the ceramic foam filter […]

Metal melt purification is a key technology to ensure the metallurgical quality of aluminum alloy materials. The aluminum casting process is smelting → standing → online Al-Ti-B refinement → online degassing → foam ceramic sheet filtration → casting. Casting is the pre-process of hot rolling, and the quality of the billet directly affects the quality […]

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 […]
