SC and SCR Single and Double spiral type SiC heating elements
1. Specification
Name: SiC Heating Element
Shape: ED, SC, SCR, Dumbbell, U, W and other special shape
Usage temp: Up to 1400C
Product process: Made into blank, silicided under high temperature
and re-crystallized.
Silicon carbide heating elements can be used in the furnace
temperature 600C-1600C, directly in the air use as well, and it
need not any protective atmosphere. Because of SiC heating elements
well performance, they are widely used in high temperature furnace,
ceramics, glass, analysis and test, semiconductor, science research
etc.
2. Character
High-applied temperature, anti-oxidization, anti-corrosion, long
service life, little deformation, easy installation and
maintenance.
3. Application
Used in various high temperature electric furnaces and other
electric heating devices, such as in the industries of magnet,
ceramics, metallurgy, glass, and machinery.

5. Packing and shipping
Packing: from the inside to outer packaging, is foam sponge,
carton, wooden case.
Transport modes: Sea or Air transportation, TNT, DHL express or
FedEx.
6. Attention
1) In order to keep furnace temperature and the charges uniform of
each element, before installation resistance distribution must be
carried.
2) As the element is very brittle, be careful while install and
maintain to avoid any damage.
3) When start to operate the furnace, raise voltage slowly and
gradually, never give full load at one time.
