The filtration of primary aluminum is to allow liquid aluminum to pass through a filter composed of neutral or active materials, so that the inclusions in the melt are mechanically isolated, or chemically react with the active materials to separate the melt from the slag. There are many filtering methods for aluminum and aluminum alloys, […]

In order to meet the different requirements of different separation objects, filtering methods and equipment are varied. According to the filtration mechanism, two types of filter cake filtration are available: cake filtration and deep filtration. Filtration Mechanism In fact, the pore size of the filter medium used in filter cake filtration is not necessarily smaller […]

Filter medium filtration is an operation in which a certain porous substance is used as a medium to treat the suspension. Under the action of external force, the liquid in the suspension passes through the pores of the medium and the solid particles are intercepted, thereby achieving solid-liquid separation. According to the different places where […]

Ultra-thin high-speed casting and rolling technology aims to increase production speed, reduce slab thickness, improve slab quality, further refine grains, increase yield limit, corrosion resistance, impact resistance, reduce plate thickness and improve plate shape, and increase productivity, to reduce the number of subsequent cold rolling, and even achieve the goal of near net shape casting. […]

Electromagnetic casting and rolling (or called magnetic fluid casting) is to apply alternating special electromagnetic field in the casting area of ​​continuous casting and rolling of aluminum alloy to form aluminum alloy magnetic fluid casting and rolling technology. The purpose is to replace the effect of the modifier with the effect of the electromagnetic field […]

Recent survey data from the Brazilian Aluminum Association show that more than 96% of the aluminum cans consumed in the country are recycled, with the highest recycling rate in the world. According to the survey, it takes only 60 days on average for an aluminum can to be thrown into the trash can to return […]

Automobile manufacturer Audi Hungary announced that it will implement a closed-loop aluminum recycling project in 2021. The company uses 38,000 tons of aluminum in automobile production every year. Taking into account the energy-intensive nature of aluminum production, Audi Hungary tries to maximize energy efficiency by using recycled aluminum. Audi Hungary stated that the aluminum recycling […]

The purification effect of aluminum alloy melt is mainly determined by dissolved hydrogen and non-metallic inclusions. Hydrogen is the most important factor leading to the formation of porosity; non-metallic inclusions can become the heterogeneous core of pores and promote the formation of porosity. Due to the “uncertainty” of its behavior, the porosity changes greatly, which […]

The rotating degassing purification method uses a rotating nozzle to spray gas flux from the bottom of the aluminum alloy melt. During the rotation of the nozzle, the fluid sprayed from the nozzle blades produces a strong stream, which can produce more than a single tube Or multiple tubes with smaller bubbles, at the same […]

Although there are many process methods for the refining of aluminum alloy melt, they still cannot meet the production needs of the aluminum industry, especially the production of military aluminum alloys such as aerospace. At present, refining and purification in the production process of cast aluminum alloy is still a basic problem, it has not […]
