Aluminum alloy melting point of metal Mg is 649 ℃, the ignition point of Mg is 500 ℃, which is much lower than the melting point of aluminum 660 ℃. Therefore, during the aluminum alloy smelting process, the metal Mg is easy to burn in the atmosphere of the aluminum smelting furnace, resulting in Mg […]

Compared with conventional size ingots, the difficulty in aluminum alloy casting process of large-scale Al-Mg alloys is that due to the increase in the size of the ingots, the depth of the molten pool increases during the melting process, and the chemical composition of the molten pool is difficult to stir during the mixing process. […]

With the development of various industries in the society, the demand for aluminum alloy has gradually increased, so the aluminium refining process is also particularly important. Aluminium Refining Process Loading. The pre-made alloy ingots and high-quality reheating materials, and then the fol alloy is added, and the alloy elements are added later. Temperature control. Strictly […]

Filtering of Molten Aluminum is a method of removing impurities by letting the aluminum alloy melt pass through a filter made of neutral or active materials, so as to separate solid inclusions suspended in the melt. According to the filtering properties, it can be divided into two categories. The filtering method of molten aluminum can […]

The ceramic filter board is referred to as CFF (ceramic foam filter). Ceramic Foam Filter CFF is a sponge-like product made of aluminum oxide, chromium oxide, etc. CFF has a unique three-dimensional network skeleton and interpenetrating pore structure. PPI is the number of holes per inch of length is used to express its specifications. The […]

Ceramic Foam Filtration is widely used for molten aluminum filtering. Molten aluminum filtering is an important step in the aluminum casting process. After the aluminum melt is refined in the smelting furnace, refining in the static furnace and online refining, the gas content has been greatly reduced, and it is basically in the critical minimum […]

Degassing With Inert Gas is widely used in the metal casting process. The melt and dissolved hydrogen do not react with chemical reactions and do not dissolve in aluminum, such as nitrogen and argon, usually using nitrogen. When the inert gas is blown into the melt, many fine bubbles are formed. When the bubbles pass […]

Methods Of Degassing In Foundry main include flux refining and degassing with inert gas. Inert gas is continuously blown into the melt, and the refining method in which the oxidized inclusions and hydrogen are brought to the liquid surface during the floating of the bubbles is called inert gas refining. The reason why blowing inert […]

Degassing with Nitrogen has been gradually eliminated in the modern aluminum industry, fluxes are generally used together with nitrogen. Use active gas chlorine as a purifying agent (chlorination method). In the chlorination method, when the chlorine gas is passed into the aluminum liquid, a lot of abnormally small bubbles are generated, which are fully mixed […]

The process and operation process of removing gas, inclusions and harmful elements from the melt to obtain pure aluminum liquid is called refining. Some people call it purification. There are many refining methods for aluminum alloy, which can be divided into three types according to refining position: pre refining before furnace (such as ladle refining), […]
