Aluminum alloy purification adopts smelting furnace nitrogen powder injection refining and international advanced degassing filtration system. The online degassing system adopts rotor gas refining technology, which has high degassing efficiency and can achieve a satisfactory hydrogen removal effect, ensuring the casting The internal quality of the ingot. Non-metallic debris and gas (mainly H2) in the […]

Air slip casting is also called gas-pressurized hot top casting. It is a new casting technology developed on the basis of the hot top, which introduces a mixture of air and lubricating oil at the junction of the lower edge of the hot top and the mold, so that oil/gas mixture lubrication heat curtain is […]

The pouring temperature of the cast-rolling production is the melt temperature in the front box. Because the melt temperature in the front box is easy to measure. On the other hand, the temperature of the melt flowing into the liquid cavity in the front box melt temperature casting zone has a small difference during normal […]

Aluminum foil has a series of advantages such as light weight, airtightness, good coating, non-toxic and moisture-proof, so it is widely used in the national economy and people’s daily life. It is currently mainly used in packaging, transportation, and construction. Aluminum foil factories generally use the casting and rolling method to produce billets. To produce […]

What is degassing aluminum? Degassing aluminum is mainly to purify hydrogen in molten aluminum. During the smelting process of cast aluminum alloy, there will be a large amount of hydrogen in the molten aluminum. When the molten aluminum solidifies at 660°C, the solubility of the hydrogen will drop sharply. Due to the fast cooling rate […]

A new type of online degassing equipment developed by AdTech – online degassing refining device. The molten aluminum flows through the degassing box, and the inert gas forms a large number of diffused small bubbles in the aluminum liquid through the rotating rotor nozzle, so that hydrogen diffuses into the small bubbles, and as the […]

As an important branch of the three major categories of foam ceramics (alumina, silicon carbide, and zirconia), alumina ceramic foam is also the earliest used ceramic foam. It is widely used in the aluminum and alloy casting industry. At present, with the continuous improvement of the performance requirements of aluminum and aluminum alloy products, new […]

The floatation method is currently the most widely used degassing method of molten aluminum. The principle is to pass an inert gas or an active gas insoluble in the molten aluminum into the molten aluminum, or add a chlorine salt (chloride) to react with the molten aluminum to generate a gas, which generates a large […]

The filtration of molten metal is an industrial practice. In particular, it is widely practiced in the art to use a mesh foam filter for molten aluminum. As we all know, the fire resistance and chemical stability of the filter material are essential to obtain effective inclusion retention and to avoid the release of reaction […]

The production requirements of flux for aluminum foundry meet the strict general quality requirements of raw materials (commercial purity, uniform size, moisture content less than 1%), and are used in the manufacturing process. The control of these variables ensures consistent products and consistent performance. For the history of most aluminum foundries, powdered fluxes have been […]
