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 […]

In order to make aluminum and its alloys pure, with less gas and inclusions, the molten aluminum or aluminum alloy is refined (or called purification). The melting temperature of aluminum and most aluminum alloys is 700~750℃, and the casting temperature is slightly lower than the melting temperature. Melt refining is to remove gases, oxides and […]

Al-Si alloy has many inherent advantages, which determine its increasingly important position in the industry and more and more extensive applications. However, the main defects such as pores, inclusions and impurities in aluminum seriously affect the quality of aluminum alloy and its products. Especially for some high-performance aluminum applications, the impact of these defects becomes […]

The equipment used in the production of aluminum foil, in addition to the melting, casting, rolling, finishing and heat treatment equipment of traditional aluminum alloy rolled products, the most critical is the purification equipment for aluminum. Purification Equipment for Aluminum Under normal circumstances, different aluminum alloy manufacturers will choose the production equipment suitable for their […]

The purification method in which the melt passes through a filter made of neutral or active materials to separate the solid inclusions suspended in the melt is called filtration. The filtration method is the most effective and reliable method to remove non-metallic inclusions in aluminum melt. According to the filtering properties, the filtering method of […]

Due to the limited development of furnace treatment and purification technology, the major research and development objects of major aluminum processing and casting companies in the world are the technology of melting the melt outside the furnace. The main development direction is to continuously improve the purity of the melt and continuously pursue high efficiency […]
