ED Type Silicon Carbide Rod
Compared with traditional heating elements, the ED-type silicon
carbide rods possess numerous remarkable advantages.
Firstly, in terms of materials, the ED-type silicon carbide rods
are mainly made of silicon carbide, while other elements may use
different materials. This enables the silicon carbide rods to have
a superior performance in high-temperature resistance. Its
equal-diameter structural characteristic is also unique. The
diameters of the heating part and the cold end are the same,
ensuring the uniformity of heat distribution. In contrast, some
traditional heating elements may have the problem of uneven
heating.
The heating part of the silicon carbide rod is formed by pressing
and sintering high-purity silicon carbide particles through special
processes, and the internal conductive network is more stable and
efficient. In comparison, the heating mechanisms of some
traditional elements may not be stable enough.
In terms of the working principle, when an electric current passes
through, the ED-type silicon carbide rods rely on their own
resistance characteristics to convert electrical energy into
thermal energy, with a remarkable heating effect. When heated in
the air, they can reach a high temperature of around 1400℃ - 1500℃
and form an antioxidant silicon dioxide film, thus prolonging the
service life. However, other elements may be prone to damage at
high temperatures or lack an effective antioxidant protection
mechanism.
