Molten Aluminum Filter Spain Aluminium can improve the purity of aluminum rods in the melting and casting process, so that the aluminum liquid has high purity, less floating impurities, and the aluminum liquid flow rate is gentle, so that the cast aluminum rods have excellent physical and chemical properties and Machining performance, so as to meet more demanding conditions of use, and extend the service life of aluminum products.
With the development of modern technology and the demand of modern industry, materials science, as the three pillar industries of the 21st century, is developing in the direction of high specific strength, high strength, high toughness and other comprehensive properties.
For a long time, cast aluminum alloys have achieved great development in industrial applications due to their low price, light weight, and reliable performance.
Especially with the increasingly urgent requirements for lightweight rail transit materials in recent years.
As the most widely used A356 aluminum alloy in cast aluminum alloys, it has good casting fluidity, good air tightness, small shrinkage rate and small hot cracking tendency. After modification and heat treatment, it has good mechanical properties, physical properties, and corrosion resistance. Compared with the steel wheel valley, the aluminum alloy wheel is lighter in weight, safer, more comfortable, and energy-saving. It has been widely used in the automobile and aviation industry because of its better machining performance.
Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process.
According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 categories.
Aluminum rod casting process
An aluminum rod melting and casting process, characterized in that the process includes the following steps
1. Prepare aluminum ingots and auxiliary materials, and add them to the smelting furnace one by one.
2. The aluminum ingot and auxiliary materials are smelted at a temperature of 900°C to 970°C to obtain an aluminum melt, and the temperature of the aluminum melt is between 700°C and 760°C.
3.After the aluminum ingot is fully melted, stir and slag off.
4. Put the refining agent into the powder sprayer and blow in nitrogen for refining. After refining, the temperature of the aluminum solution is between 730℃～760℃.
5. Casting at a temperature of 710°C to 730°C to obtain a cast rod; S6. Inspection of the cast rod, sawing and storage.
The aluminum rod production line is roughly divided into melting and casting workshop, mold workshop, extrusion workshop, aging workshop, packaging workshop, finished product warehouse, and aluminum rod warehouse.
Adtech, a supplier of Molten Aluminum Filter Spain Aluminium, introduced the process of aluminum rod casting.
Ingredients: According to the specific winning number that needs to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials. Smelt
The prepared raw materials are sold in batches according to the process requirements of Tianjin Industrial Aluminum Profiles, and they are melted in the melting furnace, and the slag and gas in the melt are effectively removed by degassing and slagging refining methods.
Under certain casting process conditions, the molten aluminum is cooled and casted into round casting rods of various specifications through a deep well casting system.
Extrusion is a means of forming profiles. First, design and manufacture a mold according to the profile product section, and use an extruder to extrude the heated round cast rod from the mold Dongguan special-shaped industrial aluminum profile. The commonly used grade 6063 alloy is also subjected to an air-cooling quenching process during extrusion.
