Ceramic Foam Filter Prime Aluminum Pakistan can effectively remove large inclusions in the aluminum liquid, and adsorb micron-sized particles of fine inclusions to improve surface quality and product performance. […]
On October 24, the Chinese Central Committee of the Communist Party of China and the State Council issued the "Opinions on Completely and Accurately Implementing the New Development Concept and Doing a Good Job in Carbon Peak and Carbon Neutralization" issued on the 24th. […]
AdTech focuses on the Chinese market to help aluminum factory improve their aluminum products with degassing units, ceramic foam filters, deep bed filters, caster tips, and so on. […]
A prerequisite for the manufacture of 7-series aluminum alloys is the manufacture of high-purity primary aluminum. AdTech has been focusing on providing a one-stop service for molten aluminum purification for many years. Our main products include degassing units, ceramic foam filters, deep bed filters, caster tips, and more. […]
Why is aluminum ingots shortage in China with aluminum production capacity increasing?In recent years, with the rapid expansion of China's electrolytic aluminum production capacity, the associated warehousing industry has also developed rapidly […]
This test uses a Prefil-footprint slag measuring instrument to take samples at the outlet of the deep bed filter of the 3104 aluminum alloy melting and casting production line of an aluminum processing plant. […]
The Prefil-footprint slag measuring instrument uses the filter press method to filter and enrich the inclusions in the melt, which is a relatively advanced slag measuring method in the world. 4 J. This article uses Prefil. The footprint slag measuring instrument takes samples at the production site of an aluminum processing plant, analyzes the type and quantity of inclusions in the sample, and guides the on-site use of the deep bed filter through the analysis results. […]
Molten aluminum is easy to dissolve in hydrogen, so aluminum degassing also called degassing with nitrogen becomes the normal process for both aluminum production and aluminum casting. AdTech's degassing units can help you to remove hydrogen from the molten aluminum liquid. […]
The use of a cylindrical degassing unit is easy to cause swirl, which makes the surface of the aluminum melt intensify the absorption of hydrogen; the use of a square degassing unit can not only avoid the swirling phenomenon but also improve the distribution of the gas phase in the degassing unit, which is beneficial to aluminum Dehydrogenation of melts […]
By comparison, it is found that the bubble size has a great influence on the volume distribution of the gas phase in the degassing unit. After the large-diameter bubbles are blown into the aluminum melt approximately in a horizontal direction, most of them gather around the rotating rod and move up along the rotating rod until the free liquid surface escapes, resulting in very little gas content in the bottom and side walls of the degassing unit, even no gas exists, resulting in poor hydrogen removal effect of aluminum melt in this part of the region. […]

Figure 2 shows the liquid phase velocity distribution in a certain longitudinal section (phase angle θ= 0°.) in the degassing unit with different clearances from the bottom, where the degassing unit is square and the bubble diameter db = 1.0 mm. Since the distribution of the liquid phase velocity field is investigated, only the liquid phase section of the vanadium height where the aluminum melt is located is displayed. […]
The structure of the rotary jet degassing unit used in the calculation is shown in Figure 1. The degassing unit is a square groove with a cross-sectional dimension of 468 mm X468 mm. […]
In the spray degassing units. However, there are few literatures on the numerical simulation of the rotary jet degassing process. The literature adopts the mixture model, which cannot fully consider the coupling effect between gas and liquid, and the research content is mainly based on the cylindrical degassing unit which has little guiding significance for practical application. […]
The solubility of hydrogen in aluminum is determined by the partial pressure of hydrogen in the gas phase in contact with the aluminum melt. When the hydrogen partial pressure in the equilibrium state corresponding to the hydrogen content in the aluminum melt is greater than the hydrogen partial pressure in the actual gas in contact with the aluminum melt, the hydrogen in the aluminum melt will diffuse into the gas phase to achieve hydrogen removal. This is the principle of hydrogen removal by bubble flotation in the degassing unit. […]
