Poland China Foundry Filter

Poland China Foundry Filter

Poland China Foundry Filter uses high-quality porous foam and high-purity ceramics as raw materials, which can effectively remove non-metallic solid mixtures in aluminum and aluminum alloy melts, and is suitable for your aluminum casting industry.

Source of inclusions in aluminum alloy
1. The oxide formed by the interaction between the surface of the aluminum alloy and the oxidizing gas in the furnace gas, such as Al2O3. This oxide film can protect the molten aluminum from being oxidized.
However, once the surface film is broken, it will be wrapped in molten aluminum. Because Al2O3 has a high melting point (2050 degrees) and a higher density than molten aluminum (3.5~4.0), it will not float, so it is easy to form oxide inclusions in the casting.
2. The oxide in the charge is also an important source of oxide inclusions in the alloy. For example, aluminum ingots and master alloys contain inclusions such as Al2O3, and the aluminum rust Al(OH)3 on the surface of the aluminum ingots will directly contaminate the molten aluminum during the smelting process.

The harm of metallurgical defects to aluminum processing deformation production and the mechanical properties of the final product cannot be ignored.

Therefore, attention should be paid to the purification treatment of aluminum melt. Before the filter is used, the gas and slag content is too high, which will cause the ceramic foam filter to block. Therefore, adding a degassing device before filtering can make the purification process of liquid aluminum more smooth.

Poland China Foundry Filter can remove impurities in aluminum melt and make CFF Casthouse have long-term durability.
The primary requirement of the aluminum casting industry is to provide high-quality products to the market for use by other manufacturing units. This will benefit users because the quality of the product is very good and it provides many opportunities to improve its functionality.

In addition, the demand for refined and high-quality products may be greater than the demand for porous and rough items. Due to the presence of many impurities in molten metal and higher requirements for high-quality products, the use of ceramic filters is becoming more and more popular in these industries.

Poland is located in the middle of the European continent, northeast of Central Europe.
The southernmost point is 49°00′N, the northernmost point is 54°50′N, the easternmost point is 24°09′E, and the westernmost point is 14°08′E.
The east and northeast are respectively bordered by the “enclaves” of Lithuania, Belarus, Ukraine and Russia’s Kaliningrad region, the south is adjacent to Czechia and Slovakia, the west is connected to Germany, and the Baltic Sea to the north is far away from Sweden and Denmark.
It is 649 kilometers long from north to south and 689 kilometers apart from east to west. The total length of the boundary line is 3538 kilometers, of which the coastline is 528 kilometers long.

Polish industries include fuel-power industry, metallurgical industry, electromechanical industry, chemical industry, wood and paper industry, light industry, aviation industry, etc. The fuel-power industry is an important basic industry in Poland, of which the coal industry is the most developed. The metallurgical industry is mainly the iron and steel industry and other non-ferrous metal industries. Poland is poor in iron ore, with an iron ore self-sufficiency rate of only 35%, and the rest are imported (mainly imported from Russia, Ukraine, France, Sweden and other countries). The electromechanical industry is the largest and most important industry in Poland, including metal processing, machine manufacturing, automobiles, shipbuilding, precision instruments, transportation tools, electrical and electronic industries, among which the automotive industry is one of the largest new industries that are rapidly developing.
