In the precise world of aluminum alloy manufacturing, every slight change may affect the final product's performance. The gas hidden inside the casting is like a lurking "enemy", which may cause problems such as pores and loose tissue at any time, seriously threatening the quality of aluminum alloy products. The aluminum alloy liquid
degassing equipment is the behind-the-scenes hero in this quality defense war. With its unique technical means, it guards every checkpoint in aluminum alloy production.
The core "weapon" of the
degassing equipment is the rotary injection method. The high-speed rotating graphite rotor is like a skilled magician, turning nitrogen or argon with a purity of over 99.99% into countless tiny diffuse bubbles. These bubbles rely on the gas partial pressure difference principle to continuously "absorb" hydrogen in the aluminum liquid like a sponge absorbing water. When the bubbles slowly float up, they not only take away hydrogen but also use the surface adsorption principle to firmly "stick" impurities such as oxide inclusions to the surface, achieving double purification. Its spiral floating path allows the bubbles to fully contact with the aluminum liquid, greatly improving the purification efficiency.
In the application field, degassing equipment shows strong adaptability. In automobile manufacturing, it "escorts" the engine cylinder and wheel hub to ensure that the parts have a dense internal structure and excellent mechanical properties; in the processing of aluminum plates and aluminum foils, it ensures that the aluminum liquid has a uniform structure and avoids cracks in subsequent processing; the recycled aluminum industry is even more inseparable from it. Through efficient purification, the recycled aluminum liquid is reborn and reaches the quality standard of primary aluminum.
degassing equipment also has a rich "family". According to the mobile mode, fixed equipment is rooted in the production line and continuously processes a large amount of aluminum liquid; mobile equipment flexibly shuttles between different furnaces to meet the needs of small and medium-sized enterprises; hoisting equipment cleverly uses space and can also show its prowess in a small aluminum melting room. According to the number of rotors, single-rotor equipment is suitable for basic degassing tasks, and multi-rotor equipment can cope with complex working conditions and purify aluminum liquid with high gas content and many inclusion layer by layers.
With excellent degassing ability, this type of equipment can significantly reduce the hydrogen content of aluminum alloy liquid, and the degassing rate of some advanced equipment exceeds 90%. At the same time, a large number of inclusions are removed, significantly improving the purity of the aluminum liquid. The stable degassing effect makes the casting quality more reliable, reduces the scrap rate, and significantly improves the production efficiency of the enterprise, laying a solid foundation for aluminum alloy products to move towards the high-end market.
