Laos China Foundry Filter is used to filter and purify the aluminum ingot production process of aluminum melting and casting plants. It has good chemical stability, high specific strength, high temperature resistance, thermal shock resistance, large specific surface area, good slag removal effect, simple operation, easy to interact with other parts Advantages such as supporting and low cost.
Therefore, it has become a common purification method in aluminum alloy production. Studies have shown that ceramic foam filters used for metal casting can also reduce the hydrogen content in the aluminum melt.
The manufacturing method of Ceramic Foam Filter Molten Aluminium Filtration is to soak polyurethane sponge in ceramic mud, squeeze out the excess material and dry it.
Finally, high-temperature sintering forms a three-dimensional porous ceramic material, which is a curved interconnected tube with uneven thickness.
It is this uneven tube wall that plays a key role in capturing small inclusions in the aluminum melt.
This structure also increases the chance of aluminum melt contacting the ceramic part of the filter, thereby increasing the possibility of inclusions being adsorbed.
Laos China Foundry Filter has an open-cell structure, which is characterized by multiple interconnected voids that allow molten metal to pass through to remove or minimize the solids entrained in the final cast product, or to promote the melt-to-melt Impurity exchange.
Such filters may include solid filters, plates made of sintered ceramic aggregates or porous carbon plates, and foam ceramic filter plates.
In addition, since gaskets or sealing devices prevent metal from entering the sealing surface of the fixture unit, their use greatly simplifies cleaning and effectively extends the life of the unit by eliminating metal corrosion problems.
In addition, due to its elasticity, the gasket can provide enough friction to maintain the position of the filter body in the filter cavity without the need for other types of pressing devices.
The elastic sealing device should handle specific molten metal that does not wet the metal, is resistant to chemical corrosion, and is fire-resistant enough to withstand higher operating temperatures.
The land area of Laos is 236,800 square kilometers. Laos is a landlocked country located in the northern part of the Indochina Peninsula. It borders China to the north, Cambodia to the south, Vietnam to the east, Myanmar to the northwest, and Thailand to the southwest.
80% of the territory of Laos is mountainous and plateau, and is mostly covered by forests.
The terrain is high in the north and low in the south. It borders the West Yunnan Plateau in Yunnan, China in the north, the Changshan Mountains on the old and Vietnamese borders in the east, and the Mekong Valley and basins and small plains along the Mekong River and its tributaries in the west.
From north to south, the country is divided into Shangliao, Zhongliao and Xialiao. Shangliao has the highest terrain. The Chuankhou Plateau has an elevation of 2,000 to 2,800 meters and the highest peak, Pubia Mountain, is 2,820 meters above sea level.
There are mineral deposits of tin, lead, potash, copper, iron, gold, gypsum, coal, and rare earths. So far, gold, copper, potash, coal, etc. have been mined. Rich water resources.
