In the contemporary aluminum alloy smelting process, melt purification technology directly affects the quality and performance of the final product. As the core component of the rotary degassing system, the material properties and process level of the graphite degassing rotor largely determine the degassing efficiency and equipment life.
Characteristics of high-performance graphite degassing rotor
Application of high-purity isostatic graphite
SEFU graphite degassing rotor is made of high-purity isostatic graphite, and the density is controlled in the optimized range of 1.82g/cm³. This material selection ensures that the rotor has excellent thermal shock resistance and stable mechanical strength in high-temperature aluminum liquid. The isostatic pressing process gives the material isotropic characteristics, allowing the rotor to maintain uniform wear characteristics under high-speed rotation conditions.
Breakthrough anti-oxidation treatment technology
Through the self-developed surface treatment process, we have constructed a dense anti-oxidation protective layer on the graphite surface. This innovative technology has made a qualitative leap in the anti-oxidation performance of the rotor, showing a service life of more than 3 times that of ordinary products in actual applications. Especially under the harsh conditions of continuous production, this treatment process effectively delays the oxidation loss of graphite materials, bringing significant economic benefits to aluminum processing companies.
Industry application and performance
Wide range of application fields
Specially treated graphite degassing rotors are used in various high-end aluminum processing scenarios. In the field of aluminum sheet and aluminum foil casting, the rotor’s stable working cycle can reach 15-20 days; in the manufacturing process of aluminum alloy wheels, its excellent corrosion resistance ensures continuous and efficient production operation. In addition, in more challenging environments such as special aluminum alloys and recycled aluminum smelting, this rotor also shows excellent adaptability.
Stable performance output
The optimized material formula and customized structural design enable the rotor to maintain stable degassing efficiency during long-term use. By precisely controlling the porosity and surface characteristics of the rotor, we achieve efficient use of inert gas and ensure that the hydrogen content in the melt is always maintained at a low level required by the process. This stability provides reliable quality assurance for aluminum product companies.
Economic benefits and cost advantages
Direct cost savings
The longer service life directly reduces the unit time cost of the rotor. Actual application data shows that enterprises using our graphite rotors can achieve:
