Secondary aluminum smelting plants provide aluminum scrap processing and smelting, metallurgical treatment and melt refining, as well as aluminum casting or further transportation in liquid form. The treated waste is melted in batches in a furnace, and the molten salt absorbs contaminants and is renewed when necessary. The metal melt is transferred to the holding […]

There is a great need to improve the filtration and degassing of molten metal to remove or minimize impurities in the final cast product, especially for molten aluminum. In particular, when the resulting metal will be used in decorative products, such as decorative strips or products with key specifications, such as aircraft forgings and extrusions, […]

The high-speed aluminum casting process is particularly sensitive to any flow interruptions within the casting feed tip and nozzle. Any accumulation of non-metallic inclusions will interfere with the molten metal leaving the nozzle orifice. Smooth flow is important for the production of uniform casting strips. Therefore, it is important to minimize the inclusions in the […]

The dehydrogenation step is a step for removing hydrogen from molten aluminum in the degassing unit. Hydrogen is mainly produced from hydrogen contained in the fuel, water, and organic matter attached to aluminum-based metals. If it contains too much hydrogen, pinholes will be produced during the rolling of aluminum ingots, which will reduce the strength […]

In the smelting process and casting process of producing an aluminum alloy ingot from an aluminum base material, the molten aluminum is heated to 700°C or higher. Aluminum or aluminum alloy ingots are produced by melting aluminum-based metals into molten aluminum. Keep the obtained molten aluminum, remove hydrogen from the molten aluminum, remove the inclusions […]

Strict melt treatment processes such as gas flux can minimize the occurrence of processing defects in aluminum products. However, for critical applications, these have not succeeded in reducing them to a satisfactory level. Generally, aluminium melt filtration is used to reduce defects, which are mainly caused by inclusions in the melt. AdTech designed a ceramic […]

Molten aluminum comes from the most common sources, such as primary metal, scrap and remelted ingots, and usually must be purified before being cast into ingots, plates, or bars. The molten aluminum purification with inert gas (ie nitrogen or argon) can remove dissolved hydrogen, inclusions and alkali metals. In some embodiments, a halogen gas, usually chlorine, […]

In the 1980s, ceramic foam metal filtration technology was quickly and widely adopted in the market and was used for a wide range of high quality aluminum products, including rigid packaging materials, lithographic printing molds, aerospace products such as wafers, wafers, forgings and extrusions; bright decorations Decorative surface decorations, condenser tubes, foil, building profiles, cast […]

The use of ceramic filter can separate the molten aluminum with its metallic impurities from solid particulate material, mainly particles which are caught up in the scrap metal. The ceramic foam filter uses a highly porous material as an intermediate for liquid aluminum to pass through the pores, trapping solid particles on the other side […]

Aluminum scrap usually contains high concentrations of various impurities. In the case of using aluminum scrap as a part of aluminum raw materials, it is necessary to remove inclusions from molten aluminum obtained by melting aluminum raw materials. Therefore, in addition to refining processes such as degassing molten aluminum using a flux, processes for removing […]
