ED Type Silicon Carbide Rod
ED-type silicon carbide rods are mainly made of silicon carbide and
feature an equal-diameter structure, meaning that 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, with a good
conductive network being formed inside.
ED-type silicon carbide rods,With their unique performance advantages, are widely used in numerous fields. The following are some of the
main application scenarios:
Ceramic Firing
In the production of ceramics, precise temperature control is
required in multiple stages from the drying of green bodies to the
sintering of finished products. For example, during the firing
process of high-grade porcelain, ED-type silicon carbide rods can
provide uniform and stable heat, ensuring that the porcelain is
heated evenly during the heating process, thus avoiding defects
such as cracks and deformations and improving the yield and quality
of finished products.
For some special ceramics, such as ceramic cutting tools and
ceramic bearings, the requirements for sintering temperature and
temperature uniformity are even more stringent. The advantages of
the high-temperature performance and temperature uniformity of
ED-type silicon carbide rods can fully meet these requirements,
helping to enhance the hardness, toughness, and wear resistance of
these special ceramics.
Glass Processing
In the glass melting stage, ED-type silicon carbide rods can serve
as highly efficient heating elements to quickly heat the glass raw
materials to the molten state. Their energy-saving and
high-efficiency characteristics help to reduce energy consumption
and improve production efficiency.
In the annealing process of glass, ED-type silicon carbide rods can
provide a uniform temperature field, effectively eliminating the
internal stress of the glass, improving the strength and stability
of the glass, and reducing the risk of breakage of glass products
during subsequent use.
Metal Heat Treatment
They are used in heat treatment processes such as quenching,
tempering, and annealing of metal materials. Taking steel as an
example, during the quenching process, ED-type silicon carbide rods
can quickly heat the steel to the quenching temperature, and then
by precisely controlling the cooling speed, the desired
microstructure and properties can be obtained, such as increasing
the hardness, strength, and toughness of the steel.
In the heat treatment of non-ferrous metals such as aluminum,
copper and their alloys, ED-type silicon carbide rods also play an
important role. By providing uniform heating, they can improve the
processing performance and mechanical properties of metal
materials, meeting the requirements of different application fields
for the properties of metal materials.
