Furnace
Product Description
Silicon carbide heating element is a kind of non-metal high
temperature electric heating element. It is made of selected high
quality
green silicon carbide as main material, which is made into blank,
siliconization under high temperature and recrystallized.
It is the most popular type of economical heating element capable
of operating under hot and rigorous environments.

Detailed Features of SIC heater:
1. U Type SIC heater
SIC heaters are constructed to from a U-shape. Consequently Type U
have the terminals at one end for a single-phase power source.
This reduces the number terminations and cold ends thus enabling
energy savings.
2.W Type SIC heater
SIC heater with the terminals at one end, is designed for
three-phase power source applications, such as the float glass
process.
3.Spiral Type SIC heater
SIC heater with a spiral-grooved heating section, are more
resistant to heat and corrosion than conventional products and are able to
withstand operation in rigorous conditions. Single spiral elements
are provided with energy-saving, low-resistance, cold-end
terminals.
4.Double Spiral Type SIC heater
SIC heater with a spiral-grooved heating section, are more
resistant to heat and corrosion than conventional products and are
able to withstand operation in rigorous conditions. Double spiral
elements are provided with energy-saving,
low-resistance, cold-end terminals.
5.GC ( Dumb bell type )and GD (Rod)Type SIC heater
GC and GD type SIC heater is made from high-density,high-purity
silicon carbide ,which is the most popular type of economical
heating element capable of operating under hot and rigorous
environments.
Notice for using and installing SIC heater
1. Be protected against damp during storing or installing to ensure
the performance ;
2. Divided before assembling. The tolerance of the resistance of
each one cannot exceed by 10% each other;
3. Be careful when using and maintaining;
4. When operating the electric furnace at the beginning, the
voltage should be increased slowly and cannot be
fully loaded at once. Otherwise the larger current will be resulted
in the damage of heater.
5. When heater is damaged and need to be changed, the resistance of
new ne should follow the increasing resistance.
If many are damaged or resistance increased too much, heater should
be changed.
