MoSi2 Rod Heating Element introduction :
1. Mosi2 heating element is a kind of resistance heating element
with high temperature resistance, oxidation resistance and low
aging based on molybdenum disilicide.When used in high temperature
oxidation atmosphere, a layer of bright and compact quartz (SiO2)
glass film is formed on the surface, which can protect the inner
layer of si-mo rod from oxidation, so the element of si-mo rod has
unique high temperature oxidation resistance.
2. Under the oxidizing atmosphere, the maximum operating
temperature is 1800, the resistance of the heating element of
silicon molybdenum rod increases rapidly with the temperature
increasing, and the resistance value is stable when the temperature
is constant.Under normal conditions, the resistance of elements
does not change with the service time, so the new and old elements
can be mixed.
Heating Element MoSi2 Replacement
If there is a damaged part found in the process of operation, the
first thing you should do is determine its location and get all the
combination elements ready. After that, you should separate the
wire the damaged element clipped to from the screw which is
connected to the generatrix. Then remove the remained refractory
wool and pull out the refractory stoppers. Insert the new
combination elements into the furnace from its roof. Connect all
the wires and get the refractory wool filled, and finally raise the
temperature.
Physical property of molybdenum disilicide heating element MoSi2
rod:
| Volume Density | Bending Strength | Vickers Hardness | Porosity | Water absorption | Heating Elongation Rate |
| 5.5g/cm³ | 15-25kg/cm² | (HV)570kg/mm² | 7.4% | 1.2% | 4% |
Chemical Properties
Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film
is formed on the surface of element owing to the high temperature
combustion, which prevent Mosi2 from oxidizing more. When the
element temperature is higher than 1700 °C, the film becomes
melting. It’s not suitable for long time use in the temperature
range of 400-700°C, otherwise, the element will be powdering for
the strong oxidation under low temperature.
