Graphite baffle for degasser
Graphite baffle for a degasser is a component used in the degassing process of molten metal, particularly in non-ferrous metal casting such as aluminum. The baffle plate is placed near the graphite shaft during the degassing process.
Product Info
Main function of graphite baffle for a degasser is to guarantee a smooth melt surface during treatment. This is crucial for achieving effective degassing and melt cleaning, leading to improved quality of the castings. The baffle plate is available in different shapes and lengths to suit various crucible and transport ladle designs.
In addition to the baffle, the degassing unit also includes a graphite shaft and a rotor. The graphite shafts are available in different diameters and lengths. The rotor, which is used in conjunction with the graphite shaft, helps distribute fine inert gas bubbles widely through the melt. This results in short treatment times and effective degassing.
Overall, the use of a graphite baffle in a degasser contributes to reduced gas porosity and hard inclusions in castings, reduced machining costs, and consistent mechanical and physical properties. It's an essential part of the degassing unit in foundries.
Application
Graphite baffle for degassers has several applications, particularly in the metal casting industry.
1. Melt Treatment: The graphite baffle is used in foundry degassing units for the degassing and cleaning of aluminium alloys. It helps distribute fine inert gas (usually Nitrogen or Argon) widely through the melt while maintaining a smooth melt surface. This results in short treatment times, effective degassing, and melt cleaning.
2. Quality Improvement: The use of graphite baffles in degassing units can lead to reproducible results, reduced gas porosity and hard inclusions in castings, reduced machining costs, and consistent mechanical and physical properties.
3. Smooth Melt Surface: A graphite baffle plate is placed near the graphite shaft and guarantees a smooth melt surface during treatment. It is available in different shapes and lengths.
4. Non-Ferrous Metal Casting: With the increasing demand for non-ferrous metal castings, especially aluminum and aluminum alloy, graphite baffles are used in rotary degassing to remove impurities from the melt and provide cleaner, better quality metal.
5. Efficiency Improvement: The graphite baffle is part of the rotor design, which is key for optimal cleaning and degassing of the melt. The rotor must fulfill several functions, and the graphite baffle plays a crucial role in this.
