GDU type Silicon Carbide Heating Elements for Industrial Electric Furnace
1. Advantage:
Our silicon carbide heating elements adopt the latest cold-end production technology, which has high-quality heat and cold-end resistance ratios, energy-saving, and long life. At the same time, it avoids the damage to the furnace body caused by the excessively high temperature of the cold end.
2. Description
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.
3. SiC heating elements standard size:

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.
4. 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. Technical Parameters:

6. 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.
7. 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.
