1700C 1800C U Type Electric MoSi2 Rods Resistance Heating Element
Mosi2 Electric Heating Elements Application:
Silicon molybdenum rod resistive electric heating element is a kind
of resistance heating element made of molybdenum disilicide based
on high temperature and oxidation resistance. When used in a
high-temperature oxidizing atmosphere, a layer of bright and dense
quartz (SiO2) glass film is formed on the surface, which can
protect the inner layer of the silicon-molybdenum rod from
oxidation, so the silicon-molybdenum rod element has unique
high-temperature oxidation resistance.
In an oxidizing atmosphere, the maximum operating temperature is
1800 ℃, the resistance of the silicon molybdenum rod electric
heating element increases rapidly with increasing temperature, and
the resistance value is stable when the temperature is unchanged.
Under normal circumstances, the resistance of the element does not
change with the length of use. Therefore, the new and old silicon
molybdenum rod heating elements can be mixed.
According to the structure, working atmosphere and temperature of
the heating equipment, the correct selection of the surface load of
the electric heating element is the key to the service life of the
silicon molybdenum rod electric heating element.
