The principle of SNIF purification is to blow inert gas or inert gas containing a small amount of chlorine into the melt. During the purification process, the aluminum alloy melt enters the first purification zone through the population of the device, is purified by the rotating nozzle, and then enters the second purification zone through […]

Furnace treatment is mainly used in small and medium-sized aluminum processing plants, not only the slag removal effect is not good, but also the melt has the possibility of secondary pollution. In order to improve the purification treatment effect and ensure the stability and reliability of the melt quality, continuous purification treatment outside the furnace […]

Flux refining method is to achieve the purpose of slag removal by adsorbing, dissolving oxide inclusions and adsorbing the hydrogen in molten aluminum, floating up to the liquid level and entering the slag. The flux is generally composed of a mixture of alkali metal or alkali metal halide. After the aluminum liquid is added, the […]

Purification treatment of aluminum alloy melt can be divided into in-furnace treatment and out-of-furnace treatment according to different production links. The purification technology in the aluminum alloy melt furnace can be divided into adsorption purification treatment technology and non-adsorption purification treatment technology. The adsorption method mainly relies on the refining agent to produce the effect […]

In the field of defense technology such as aerospace, the application of large aluminum alloy components is increasing, and the requirements for components are getting higher and higher. In addition to ensuring its chemical composition, mechanical properties and dimensional accuracy, castings are also not allowed to have defects such as shrinkage, porosity, leakage, and slag […]

Inclusions and gases in the metal have a significant impact on the strength, fatigue resistance, corrosion resistance, and stress corrosion cracking performance of the material. Effectively controlling the oxidized inclusions in the melt to improve the quality of cast rods and rolled plates has become a common goal pursued by the metallurgy, casting and material […]

Aluminium Refining process: inert gas storage tank → online degassing unit gas control cabinet → graphite rotor nozzle → processed aluminum alloy melt → purification. The working principle of Aluminium Refining degassing treatment: a degassing unit is placed between the holding furnace and the casting machine, and the nitrogen blown into the aluminum alloy melt […]

In recent years, it is generally accepted that the Sr Modifier inhibits the eutectic, thereby increasing the primary crystal content and increasing the feeding resistance in the eutectic stage. At the same time, the modification treatment causes the morphology of the solid/liquid interface during the solidification of the eutectic to change from the irregular shape […]

Modification treatment changes the eutectic silicon from coarse flakes to fine fibrous or lamellar flakes, thereby improving the properties of the alloy. The modification treatment is mainly to refine the second phase or change its morphology and distribution. In this article, it mainly focuses on the eutectic silicon in the aluminum-silicon alloy. When it is […]

Grain refinement treatment is a process of purposefully suppressing the growth of columnar crystals and double columnar crystals and promoting the formation of fine equiaxed crystals. Grain refinement can not only improve the properties of the alloy, but also reduce defects such as shrinkage porosity, thermal cracking, and pinholes. Grain refinement treatment usually refers to […]
