Silicon carbide combined with silicon nitride degassing rotor used in degassing process
What is silicon carbide (SiC) and silicon nitride (Si₃N₄) composite rotors?
The degassing rotor made of silicon carbide (SiC) and silicon nitride (Si₃N₄) composite is a high-performance ceramic material rotor, primarily used for degassing and purification in the smelting of non-ferrous metals such as aluminum and magnesium. This composite ceramic rotor combines the high thermal conductivity of SiC with the excellent fracture toughness of Si₃N₄, making it an ideal choice for high-end metallurgical degassing equipment.
Our advantages
Innovative Structural Design
Gradient Composite Design: Inner layer of high-density silicon carbide ensures superior wear resistance, while the outer silicon nitride network guarantees structural strength.
Streamlined Inner Cavity: Reduces fluid resistance, improving transport efficiency by up to 30%.
Modular Connection Interface: Enables quick and easy installation and maintenance.
