The purpose of metal smelting is to smelt the chemical composition to meet the requirements and obtain the aluminum alloy melt with high purity, which creates favorable conditions for casting into ingots of various shapes. Aluminum is a very active metal. The chemical reactions that occur during the metal smelting process are irreversible. Once the […]

The recycling of scrap aluminum is a cycle from product to product, maximizing the life of resources. In this process, problems such as quality loss, energy consumption and pollutant emission are involved. The full life cycle of aluminum refers to the process of going through an infinite life cycle until it completely loses the properties […]

There are two sources of aluminum as raw materials: one is electrolytic aluminum (primary aluminum), and the other is secondary aluminum. With the increase in the amount of aluminum and the passage of time, the amount of scrap aluminum will continue to increase. All useful things will be recycled and reused. Among the metals used […]

Horizontal casting mold mostly adopts a combined structure, including distribution plates, casting platforms, and forming molds. The horizontal casting mold is not high, generally only 40-50 mm, and the effective crystallization area is about 10-30 mm. The graphite inner sleeve transverse casting mold has a small height and a short effective crystallization zone length. Therefore, […]

At present, various master alloys are generally used to replace aluminum alloys additives, because master alloys have a low melting point and are easier to quickly and uniformly melt in the aluminum melt. However, many manufacturers use scrap aluminum or low-grade aluminum ingots when producing master alloys, which contain more impurities. When using master alloys, […]

The mechanism of adsorption purification method is that the aluminum alloy melt is in direct contact with N2, Cl2 and other gases, adsorbents and refining agents and other media, so that the gases and solid oxide inclusions will interact with these media, so as to remove the gas and inclusions in the melt. The adsorption […]

In order to provide large-size, high-quality and high-quality blanks for the production of high-precision aluminum strips for aluminum processing enterprises, the electrolytic aluminum plant adopts the fully automatic low-level (LHC) combined mold casting technology and uses the electrolytic raw aluminum liquid to directly batch for hot rolling. Aluminum alloy slab ingots can cast 2~5 slabs […]

The electrolytic aluminum liquid directly produces cast-rolled coils, although it can save costs and reduce consumption. However, compared with remelted aluminum ingots, the excessively high proportion of electrolytic aluminum liquid will directly lead to problems such as high hydrogen content, high slag content, high alkali metal content, and coarse grain size of cast-rolled slabs. Therefore, […]

Due to the relatively high content of alkali metals in the electrolytic aluminum liquid, the refining process needs to be strengthened. Electrolytic Aluminum Refining Process Use 5%~10% concentration of chlorine and argon to refine the furnace for no less than 15 minutes, or use high-quality refining agents for multiple refining. After the flux refining is […]

Above the water-cooled crystallizer, install a heat-preserving cap made of insulating film material, also called hot top cap, pouring cup. The requirements for the hot top cap are no chemical reaction with molten aluminum, no moisture absorption, no oil absorption, no wetting to molten aluminum, high-temperature resistance, good insulation performance, thermal shock resistance, good strength, […]
