Details:

1.The General Description ofsilicon carbide heater

1).production process:made into blank,silicided under high temperature and re-crystallized.

2).character: high-applied temperature ,anti-oxidization ,anti-corrosion ,long service life ,little deformation,easy installation and maintenance.

3). usage: used in various high temperature electric furnaces and other electric heating devices,such as in the industries of magnet,ceramics,metallurgy ,glass,and machinery.

4).physical properties of element

specific gravity	2.6~2.8g/cm³	bend strength	>300kg
hardness	>9 MOH′S	Tensile strength	>150kg/cm³
porosity rate	<30%	radiancy	0.85

5).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

2. Advices of using the element

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.
