DB ( Dumbbell ) Type Silicon Carbide Heating Element for Furnaces
The silicon carbide (SiC) heating element is a key component in many high-temperature applications. Its non-metallic nature gives it several advantages over traditional metallic heating elements. The use of ultra pure green hexagonal silicon carbide as the main material provides excellent thermal conductivity and resistance to high temperatures.
The manufacturing process of making billets and silicon crystals at 2400 °C results in a product with high structural integrity and stability. In an oxidizing atmosphere, the ability to operate at 1450 °C is a significant advantage, as it allows for use in a wide range of industrial processes. The long continuous service life of 2000 hours indicates its reliability and durability.
The evolution of dumbbell shaped components with enlarged cold ends is an interesting aspect of heating element design. The initial design was aimed at reducing the cold end temperature by increasing the cross-section and reducing resistance. However, modern technology has made it possible to achieve terminal cooling through other means. The reduction in electrical resistivity of the cold end material has eliminated the need for oversized cold ends. Non dumbbell or ED type components offer a more streamlined and efficient design.
From a technical perspective, these developments in heating element design reflect the continuous improvement in materials science and manufacturing processes. As technology continues to advance, we can expect further enhancements in the performance and functionality of silicon carbide heating elements.
