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 […]

Porosity is the percentage of the total volume of cavities in the ceramic foam filter plate product relative to the total volume of the filter plate product. Porosity determines the filtration capacity of the ceramic foam filter plate per unit volume. The greater the porosity, the greater the filtration rate of the filter plate and […]

The ability to degas molten aluminum is generally achieved by using an inert gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced into the melt, they collect hydrogen as they float to the surface. The best possible situation is […]

Литейный пенокерамический фильтр эффективно удаляет с металла вредные примеси, такие как включения и газы, и улучшать внутреннее качество металла. Алюминиевые литейные заводы используют пенокерамические фильтры для получения алюминиевых слитков с удовлетворительными результатами. Кроме того, предварительные результаты дает применение пенокерамических фильтров для прецизионного литья, алюминиевой фольги и алюминиевых стержней. После использования литейного пенокерамического фильтра сопротивление потоку […]

The main advantage of the ceramic filter for Greek Aluminium is to effectively eradicate the slag inclusions through the filter plate, and remove the micron-sized fine inclusions in the aluminum liquid. At the same time, because the ceramic filter plate filters out fine inclusions and reduces the effective number of crystal nuclei in the molten […]

The smelting of aluminum alloys has the characteristics of high heat consumption, easy oxidation, easy absorption of hydrogen, and easy absorption of impurity metals. (1) Consume a lot of calories. Although aluminum has a low melting point, it has a large latent heat of fusion, a large specific heat, a small blackness, and a strong […]
