Foam Ceramic Filter Icelandic Aluminum is used to purify the molten aluminum in the aluminum plate melting and casting workshop, remove large inclusions in the molten aluminum, and adsorb micron-sized particles of fine inclusions.
The internal winding path is used to filter and purify the aluminum melt and purify the aluminum alloy liquid. After filtration, the viscosity of the aluminum alloy liquid is reduced, and the fluidity of the aluminum alloy liquid is increased by 10%-15%. It can improve the surface quality, improve the performance of the product, improve the effect of the microstructure, and increase the yield. It is widely used in the production of aluminum profiles, aluminum foils, and aluminum alloys.
Icelandic Aluminum purchases through sales@adtechamm.com for casting aluminum flux filtration equipment for continuous casting and semi-continuous casting.
The technicians of Japan Aluminium believe that in the casting process, the ceramic foam filter is an effective tool to achieve the metallurgical purity of the molten metal. The filter can also stabilize the filling of the mold, thereby preventing defective castings from appearing.
Characteristics of Foam Ceramic Filter Icelandic Aluminum
1. Accurate dimensional tolerance
2. Stable chemical composition
3. The highest filtration efficiency
4. Excellent strength
5. Resistance to corrosion of molten aluminum and alloys
Aluminum alloy is easily inhaled and oxidized during the casting process. Therefore, there are different degrees of gas and various non-metallic inclusions in the melt, leading to defects such as pores, pores and inclusions in the ingot.
Significantly reduce the mechanical properties, processing properties, fatigue resistance, corrosion resistance and anodic oxidation properties of aluminum, and even lead to product scrapping.
The contract for the construction of an aluminum plant in Iceland was signed in 1966. By then, negotiations between the Swiss company Alusuisse and the Icelandic government had been going on for several years. The Iceland Aluminium Company (ISAL), now Rio Tinto Iceland Ltd., was established and soon started construction in Straumsvík. Three years later, Iceland began to produce aluminum, and on July 1, 1969, it began to produce aluminum.
Since then, the company has changed a lot and now produces approximately 212.000 tons of aluminum per year.
In the foundry workshop, the molten aluminum is poured from the crucible into the mixing furnace. In the mixing furnace, various metals are added to the aluminum to make its chemical composition meet customer requirements. This composition determines the strength, toughness and corrosion resistance of aluminum.
When the correct composition is obtained, the aluminum is treated with sodium to reduce hydrogen, sodium, and solid impurities. It is then poured into the casting machine through a filter and Natrium processing system to remove the last impurities before casting. In the foundry, the slabs are cast in four casting machines. A rolled slab is a flat aluminum rod, which may vary in size and composition. The foundry produces approximately 200 different products.
The waste generated in the foundry is recycled as much as possible. The company melts the cuttings for reuse. The dust produced by sawing and the filter used to clean the metal are sold for recycling. Aluminum slag is a by-product composed of pure aluminum and alumina and is also sold for recycling.
