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 |
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.
Inquiry data should be clear:
a). Outer diameter (OD)
b). Length of Hot zone (HZ)
c). Length of Overall (OL)
d). Resistance (at 1050°c +/-50°c)
