ED Type Silicon Carbide Rod
Description: The ED type silicon carbide rod is mainly made of
silicon carbide and features an equal-diameter structure, that is,
the diameters of the heating part and the cold end are basically
the same. The heating part is formed by pressing and sintering
high-purity silicon carbide particles through special processes,
and a good conductive network is formed inside.
Working Principle: When an electric current passes through the
silicon carbide rod, due to its own resistance characteristics,
electrical energy will be converted into thermal energy, thus
making the silicon carbide rod heat up. When heated in the air, the
surface temperature of the heating part of the element can reach
around 1400℃ - 1500℃, and a dense silicon dioxide film will be
formed on the surface. This film has an antioxidant effect and can
protect the silicon carbide structure inside the silicon carbide
rod to a certain extent, thus prolonging its service life.
Advantages:
- Long Service Life: Due to the high-temperature resistance of its
material and the antioxidant film formed on the surface, the ED
type silicon carbide rod can work stably in a high-temperature
environment for a long time. Generally speaking, its service life
can reach thousands of hours or even longer, reducing the frequency
of replacing heating elements and lowering the maintenance cost of
the equipment.
- Energy-saving and High-efficiency: The equal-diameter structure
makes the heating efficiency of the silicon carbide rod higher,
enabling it to convert electrical energy into thermal energy more
effectively. Under the same power input, the ED type silicon
carbide rod can generate more heat, thus improving the energy
utilization rate of the heating equipment and saving energy costs
