Brief: Let’s dive in — see this solution in action and notice the key moments. This video provides a detailed walkthrough of the specially grooved silicon carbide ceramic flange, demonstrating its precision positioning and connection capabilities in high-temperature environments. You'll see how its unique design and material properties ensure high rigidity and reliability in demanding applications like semiconductor equipment and high-temperature mechanical systems.
Related Product Features:
  • Manufactured from reaction bonded silicon carbide for exceptional mechanical properties and thermal stability.
  • Features a precision-machined special-shaped central groove and five evenly distributed through-holes for accurate positioning.
  • Offers super high rigidity and hardness, ensuring minimal deformation and high positional accuracy.
  • Capable of long-term operation at temperatures up to 1550°C without softening or deforming.
  • Excellent thermal shock resistance withstands rapid temperature changes without cracking.
  • Outstanding chemical stability resists acidic, alkaline environments, and molten metals.
  • Low coefficient of thermal expansion ensures stable fits and connections across a broad temperature range.
  • Ideal for precision equipment positioning, mechanical connection, and transmission systems in extreme environments.
FAQs:
  • What is the main difference between a Silicon Carbide flange and a Zirconia flange?
    The main differences lie in thermal conductivity and temperature resistance. Silicon Carbide has excellent thermal conductivity and a maximum use temperature of 1550°C, which is much higher than Zirconia's approximately 1100°C. However, Zirconia generally has higher fracture toughness at room temperature.
  • Can the central special-shaped groove be made into other non-standard shapes?
    Yes. With strong CNC machining capabilities, we can customize various complex special-shaped grooves according to your drawings, such as D-shapes, squares, polygons, or specific spline grooves.
  • Will this flange disc gall or seize with connecting bolts at high temperatures?
    If directly connected with common metal bolts, there is a risk of diffusion bonding at extremely high temperatures. We strongly recommend using high-temperature alloy bolts combined with specialized anti-galling coatings or ceramic washers for high-temperature applications.
