ED Type Silicon Carbide Rod
Silicon carbide rods, also known as silicon carbide heating
elements, are mainly made from high-quality green silicon carbide
as the core raw material. In the manufacturing process, techniques
such as high-temperature silicification and recrystallization are
employed, ultimately resulting in this type of rod-shaped
non-metallic high-temperature heating element.
Compared with metal heating elements, silicon carbide rods have
many prominent advantages. They can operate stably under relatively
high temperature conditions, possess excellent oxidation
resistance, and have good tolerance to various corrosive
environments. Moreover, their service life is quite long, with
minimal deformation during use, they are very convenient to
install, and the subsequent maintenance work is also easy to carry
out.
Based on these remarkable advantages, silicon carbide rods have
been widely used in various high-temperature electric furnaces and
other electric heating equipment in numerous industries, such as
magnetic materials, powder metallurgy, ceramics, glass, metallurgy,
and mechanical industries.
Among them, the ED type belongs to the standard silicon carbide
heating element. It is a high-density self-bonded silicon carbide
element. The ED type silicon carbide rods have a relatively large
range of options in terms of diameter and length.
