Grain refining aluminum alloy is a powdery particle, which is sprayed by a carrier gas (nitrogen or argon) through a special powder refining sprayer to the bottom of the aluminum molten pool, forming many bubbles in the aluminum liquid, and the bubbles rise from the aluminum liquid mobile. bottom. During the floating process, it is […]

After aluminum ingots enter industrial applications, they can be divided into two categories: cast aluminum alloys and deformed aluminum alloys. Aluminum castings and aluminum alloys are aluminum castings produced by casting methods. Deformed aluminum and aluminum alloys are processed products of aluminum produced by pressure processing methods: plates, strips, foils, tubes, rods, profiles, wires and […]

The process of removing hydrogen from molten aluminum first takes place inside the melt. The hydrogen atoms dissolved in molten aluminum undergo migration to the periphery of the bubbles of the purifying agent (Ar or N2, etc.). At the periphery of the bubble, it is adsorbed and formed into hydrogen molecules to enter the bubble. […]

The purification technology of liquid aluminum, which is based on hydrogen removal, mainly includes bubble floatation, vacuum treatment, ultrasonic treatment, and rare earth hydrogen storage. Because of its simplicity and high efficiency, the bubble floatation method is still a widely used aluminum liquid hydrogen removal purification technology. AdTech online degassing unit adopts bubble floatation method […]

Aluminum Purification Treatment is to obtain a clean, pure and homogeneous melt. The hydrogen content and slag content of the melt will affect the quality of the ingot. Therefore, we take the following measures to improve the quality of the smelting: ① During the smelting process, control the melt temperature between 720℃ ~ 760℃, and […]

Aluminum alloy melt online purification technology refers to the refining of the aluminum alloy melt out of the furnace. The specific operation process is as follows: First, the melt is led out of the furnace, and refined gases such as chlorine mixed gas, argon and nitrogen are passed into the online refining device, and the […]

The electrolytic aluminum liquid has a high content of gas and impurities. In view of the above composition characteristics, the melt refining process must be strengthened. The refining process for aluminum usually uses refining agent and blowing with nitrogen, the quality of refining agent and nitrogen must be ensured. The production uses high-quality refining agent and […]

The aluminum alloy round bar casting platform is a tool that converts the liquid aluminum in the furnace into solid aluminum of a certain shape and specification, and is a key part of casting molding. At present, imported equipment represented by American Wagstaff has occupied the main domestic market. The hot top accessories produced by […]

After the die-casting aluminum alloy is melted and refined, the aluminum water is taken from the subcontract during the subcontracting and degassing, the time before and after the refining agent is added, the nitrogen flow of the rotating degassing aluminum, the speed of the graphite rotor, the degassing time, the diameter and height of the […]

Theoretically speaking, the purity of aluminum alloy melt should reach a high level after refining in the furnace and on-line degassing and slagging. However, the actual results are often not ideal. One of the important reasons is that the aluminum liquid passes through the launder. The slagging and gas suction conditions during the casting process. […]
