02 9月 Casting Filter Denmark Aluminium
Casting Filter Denmark Aluminium can effectively filter out large inclusions of liquid metal and a large number of small floating objects to tens of microns, thereby reducing the rate of casting rejects and welding repair rates.
Casting Filter Denmark Aluminium can improve the mechanical properties of castings, reduce the rejection rate of castings, increase the rate of finished castings, and extend the service life of metal cutting tools.
Due to the closed cells in the ceramic foam, its thermal efficiency is reduced and the heat transfer in the convection process is reduced, so that the ceramic foam has the characteristics of low thermal conductivity and good thermal shock resistance. It is an ideal heat-resistant material.
Cast aluminum filter Foam ceramic filter has many advantages such as good chemical stability, high specific strength, high temperature resistance, thermal shock resistance, and large specific surface area.
It is widely used in metallurgy, chemical industry, environmental protection and other fields.
In metallurgy, the use of ceramic foam filter plates to remove foreign contaminants in the lead melt, such as slag and inclusions, is one of the most effective melt cleaning methods.
Studies have shown that in addition to slag, it can also reduce the hydrogen content in molten aluminum.
Because of its good slag removal effect, simple operation, easy adaptation to other parts, and low cost, it has become a conventional cleaning method in the aluminum processing industry.
As the requirements for the quality of aluminum products are getting higher and higher, the requirements for the filter plate are also getting higher and higher.
There are many factors that affect fluidity, mainly the composition, temperature and solid particles of contaminants such as metal oxides and metal compounds in the alloy liquid. However, the basic external factors are the casting temperature and pressure (commonly known as casting pressure). High and low movement.
Cast aluminum filter The foam ceramic filter is very important to the quality of the aluminum melt, and has a significant impact on the subsequent processing performance and the quality of the final product. Therefore, all countries in the world attach great importance to the cleaning of aluminum smelting.
As a small open economy, Denmark generally pursues a free trade policy, and its exports and imports account for about 50% of GDP.
In 2017-20, the import volume of aluminum cans in Denmark was 42,067 tons, accounting for US$207.5 million.
The import trend of aluminum cans in 2017-20 is not obvious, with ups and downs. In 2017, Denmark imported 12,791 tons of aluminum cans, and its external revenue and expenditure were USD 55.33 million.
In 2018, the import volume of aluminum cans dropped by 2,635 tons, and the total import volume was 10,156 tons, with an amount of 49.69 million US dollars, a decrease of 20.60%.
The import volume in 2019 was 10,924 tons, an increase of 768 tons, an increase of 7.56%, to reach 56.39 million US dollars.
The forecast for 2020 also shows negative growth, a sharp drop of 25% compared to the previous year. The import volume in 2020 is 8198 tons, a decrease of 2726 tons, and the import volume is 46.17 million US dollars.
