Silicon molybdenum rods is introduced

1 silicon molybdenum rods resistance electric heating element is made of a kind of molybdenum disilicide based high temperature resistance, oxidation resistance heating elements. When used in high temperature oxidizing atmosphere, a layer of light generated on the surface of the density of quartz (SiO2) glass membrane, can protect layer of silicon molybdenum rods no longer oxidation, therefore silicon molybdenum bar element has a unique high temperature oxidation resistance.

2 under oxidizing atmosphere, new technology of silicon molybdenum rods highest use temperature is 1800 ℃, as the temperature rises, the resistance increase rapidly, when the constant temperature resistance stability. Under normal circumstances element resistance with the use of the length of time and change, therefore, both old and new silicon molybdenum rods electric heating element can be used mixed.

3 according to the structure, working atmosphere and the temperature of the heating device, to correctly choose the electric heating element surface load, silicon molybdenum rods is the key to the service life of electric heating element.

Silicon molybdenum rods electric heating element products are widely used in metallurgy, steel, glass, ceramics, refractory material, electronic components, semiconductor materials research, production and manufacturing, and other fields, especially for high performance precision ceramics, metal structure ceramics, glass fiber, optical fiber, and advanced the production of alloy steel.

4 1700 type silicon molybdenum rods temperature greater than 1710 degrees of SIO2 protective melting, due to the effect of surface tension, SIO2 ash-agglomerating into droplets, and loss of protection. Elements in continue to use under oxidizing atmosphere, SIO2 coating and regenerated, is what people often say that the peeling phenomenon of aging, so 1700 type silicon molybdenum rods should be used under the environment of less than 1700 degrees.
