Ceramic Foam Filter Spain Aluminium can improve the purity of Aluminum rods in the smelting and casting process. The liquid aluminum has high purity, less floating impurity, smooth flow rate of liquid aluminum and other good characteristics, so that the cast aluminum rod has excellent physical and chemical properties and machining properties, so as to meet more demanding conditions, and prolong the service life of aluminum products.
With the development of modern science and technology and the needs of modern industry, as three pillar industries in the 21st century, material science is developing towards the direction of comprehensive properties such as high specific strength, high strength and high toughness.
For a long time, cast aluminum alloy has gained great development in industrial application because of its low price, light weight and reliable performance.
Especially with the increasingly urgent demand for lightweight rail transit materials in recent years.
As the most widely used cast aluminum alloy, A356 aluminum alloy has good casting fluidity, good air tightness, small shrinkage and small hot crack tendency. After modification and heat treatment, aluminum alloy wheel yi has good mechanical properties, physical properties, corrosion resistance and better machining properties. Compared with steel wheel valley, aluminum alloy wheel Yi has light weight, safety, comfort, energy saving and so on, and has been increasingly widely used in the automotive and aviation industry.
Aluminum rod is a kind of aluminum product. The casting process of aluminum rods includes melting, purification, impurity removal, gas removal, slag removal and casting process.
According to the metal elements contained in aluminum rods, they can be roughly divided into eight categories.
The invention relates to an aluminum rod melting casting process characterized in that the process includes the following steps
1. Prepare aluminum ingots and auxiliary materials, and add them to the melting furnace in turn.
2. At 900℃ ~ 970℃ temperature of aluminum ingot and auxiliary material smelting, aluminum melt, the aluminum melt temperature between 700℃ ~ 760℃.
3. Stir and slag picking after the aluminum ingot is fully melted.
4. Put the refining agent into the duster for refining through nitrogen blowing, and the temperature of the aluminum solution after refining is between 730℃ and 760℃.
5. The casting rod is obtained at 710℃ ~ 730℃; S6. Check the casting rod, saw it, and put it into storage.
Aluminum bar production line is roughly divided into casting workshop, mold workshop, extrusion workshop, aging workshop, packaging workshop, finished product warehouse, aluminum bar warehouse.
Adtech, the supplier of Ceramic Foam Filter Spain Aluminium, introduced the process of Molten Aluminum rod casting.
Ingredients: according to the need to produce the specific winning number, calculate the addition of all kinds of alloy components, reasonable collocation of all kinds of raw materials. smelting
The raw materials will be prepared according to the process of tianjin industrial aluminum to be sold in batches to join the melting furnace melting, and through the degassing, slag removal refining means to effectively remove the miscellaneous slag and gas in the melt.
The molten aluminum is cooled and cast into round casting rods of various specifications by deep well casting system under certain casting process conditions.
Extrusion is the means of profile forming. First, according to the sectional design of the profile product, the mold is manufactured, and the heated round casting rod is extruded from the dongguan special-shaped industrial aluminum profile by an extruder. The commonly used grade 6063 alloy is also extruded with an air cooling quenching process.
