4.Application

It is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass metallurgy and machinery etc.

Our main products include silicon carbide heating element and Mosi2 heating element with various types such as U type, three phase type, equal diameter type, and other heterotypic.

5.Physical property of SiC heating element

Specific gravity	2.6~2.8g/cm3	Bend strength	> 300kg
Hardness	> 9MOH’S	Tensile strength	> 150kg/cm2
Porosity rate	< 30%	Radiancy	0.85

6.Recommend surface load

Furnace Temp (°c )	1100	1200	1300	1350	1400	1450
Surface load of hot zone (W/cm²)	<17	<13	<9	<7	<5	<4

7.Notes for using and installing the heater:

a)Heater should be protected against damp during storing or installing to ensure the performance of the heater.

b)In order to be sure of well-distributed load of each and groups heater should be divided before assembling.

The tolerance of the resistance of each one can not exceed by 10% each other.

c)Heater is hard and brittle, please be careful when assembling and maintaining so as to avoid damage.

d)When operating the electric furnace at the beginning, the voltage should be increased slowly and can not be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.

e)When heater is damaged and need to be changed , the resistance of new heater should follow the increasing resistance. If many are damaged or resistance increased too much, all the heater should be changed.
