25 6月 Albania China Foundry Filter
Albania China Foundry Filter can effectively remove inclusions from aluminum melt and significantly improve the quality of aluminum products. Due to the oxygen affinity of aluminum, oxides are the most common among all aluminum alloy melt inclusions.
In the modern aluminum casting industry, in the process of producing aluminum products, ceramic filter plates can effectively remove the alumina impurities in the aluminum liquid, and increase the quality of aluminum products.
If the chemical composition of the non-metallic inclusions formed in the aluminum melt is not removed, the chemical composition is very stable, and it is easy to cause cracks in the casting after solidification.
The presence of non-metallic inclusions makes it difficult to predict the mechanical properties of castings.
The influence of oxidized inclusions on the tensile properties of aluminum alloys, they believe that the main reason for the decrease in mechanical properties of aluminum alloys.
Therefore, it is very necessary for Albania Aluminium to use Albania China Foundry Filter.
Ceramic Filter Cff is widely used in the production of large aluminum processing enterprises in Russia, the Middle East and Southeast Asia.
During use, it is not only necessary to remove the aluminum melt inclusions, but also to avoid clogging of the Foundry Ceramic Filters and improve the service life of the CFF.
RUSAL engineers said
The process by which inclusions in the matrix affect the fracture of the aluminum alloy specimen can be described as
When the specimen is subjected to tensile force, severe concentrated stress occurs at the crack front edge. When the tensile stress exceeds the yield strength, plastic deformation occurs near the crack tip first, forming a plastic zone, which leads to stress relaxation and blunt crack tip.
As the plastic zone expands, the inclusions at the front end of the crack enter the plastic zone.
Because the binding force between the inclusions and the matrix is relatively weak, under the action of tensile stress, the inclusions are separated from the matrix, forming the initial micropores.
Continue to increase the load, the internal necking between the crack tip and the micro-hole intensifies, causing the crack tip and the micro-hole to quickly aggregate, and the crack starts to expand forward.
Therefore, inclusions are conducive to the formation of initial micropores and have a greater impact on the propagation of cracks.
Albania is located on the west coast of the Balkan Peninsula in Southeast Europe, bordered by Serbia and Montenegro (Mondinegro) in the north, connected with the Republic of Northern Macedonia in the northeast, Greece in the southeast, the Adriatic and Ionian Seas in the west, separated by the Otranto Strait Facing Italy.
Albania is rich in water and solar resources. There are many types of mineral resources, including oil, natural gas, asphalt, lignite, limestone, chromium, copper and nickel.
Proved oil reserves are about 438 million tons, natural gas reserves are about 18.16 billion cubic meters, coal reserves are about 794 million tons, chrome reserves are about 36.9 million tons, copper reserves are about 24.19 million tons, and nickel iron ore and nickel silicate reserves are about 364 million tons.
