Molybdenum Disilicide Heating Elements
consisting of Molybdän-Disilizid (MoSi2) with ceramic additives.
There are two qualities available:
MD 31: for max. element temperatur up to 1700 °C
MD 33: for max. element temperatur up to 1800 °C
Moly-D has the ability to withstand oxidation at high temperatures by forming a protective layer of quartz (SiO2) on its surface.
MOLY-D-Elements has a low specific electrical resistivity with a positive resistance-temperature characteristic. That means, if the temperature is increasing the resistance of Moly-D-Elements will increasing too. So, at a constantly voltage, Moly-D has a high element-power at a low temperatur which reduces the warm-up time of the furnace up to the operating-temperature and gives so an economical advantage
Because of its high temperature oxidation resistance, MOLY-D electrical resistance remains constant at constant temperature over its lifetime. This permits the use of old and new elements together in the same furnace, even if series-connected.
Typical application range for MOLY-D-Elements are:
- steel industry
- metal working industry
- glass industry
- ceramic industry, as well as laboratory furnaces
2-shank bent elements are available in the following standard sizes:
|typ||terminal-diameter Lu||heating-zone-diameter Le|
|3/6||6 mm||3 mm|
|4/9||9 mm||4 mm|
|6/12||12 mm||6 mm|
|9/18||18 mm||9 mm|
|12/24||24 mm||12 mm|
Elements with cranked heating-zone or terminals are also available.
Spacing between shanks:
|typ 3/6:||a = 20 / 25 / 40 mm|
|typ 4/9:||a = 20 / 25 / 40 mm|
|typ 6/12:||a = 40 / 45 /50 / 60 mm|
|typ 9/18:||a = 50 / 60 mm|
|typ 12/24:||a = 60 / 80 mm|
(other sizes and 4-shank elements available on request)
Max. length of heating-zone depends on element temperature
which is for
|3/6 elements:||610 mm|
|6/12 elements:||1250 mm|
MOLY-D-Elements are defined by:
- Material quality
- Diameter heating-zone in mm
- Diameter terminal in mm
- Terminal-length in mm (Lu)
- Heating-zone length in mm (Le)
- Spacing between shanks in mm (a)
example: MD-31, 6/12 mm, Lu = 400 mm, Le = 500 mm, a = 50 mm
Our Delivery programme also includes compatible metallic and ceramic brackets, connecting bands and furnace ducts.
