Silicon Carbide heating element Rod SIC heater Profile :
The Silicon Carbide heating element has high temperature, high temperature resistance, oxidation resistance, corrosion resistance, fast heating, long life, low temperature deformation, convenient installation and maintenance, and good chemical stability.
With the automatic electronic control system, the constant temperature can be obtained, and the temperature can be automatically adjusted according to the needs of the production process. Heating with silicon carbon rods is convenient, safe and reliable. Now widely used in high temperature fields such as electronics, magnetic materials, powder metallurgy, ceramics, glass, semiconductor, analytical laboratory, scientific research, etc., it has become tunnel kiln, roller kiln, glass kiln, vacuum furnace, muffle furnace, smelting furnace and Electrical heating elements for all types of heating equipment.
Chemical properties
Silicon Carbide heating element have good chemical stability and strong acid resistance. The alkaline substance has an erosive effect under high temperature conditions.
Long-term use of silicon carbide rod components above 1500 °C can have the following effects with oxygen and water vapor:
1Sic+2O2→Sio2+CO2 2Sic+4H2O=Sio2+4H2+CO2
As a result, the SiO2 content in the element is gradually increased, and the electric resistance is gradually increased, thereby aging. If there is too much water vapor, it will promote the oxidation of SiC. The H2 produced by the 2-type reaction reacts with O2 in the air to react with H2O to produce a vicious circle. Reduce component life. hydrogen (H2) can reduce the mechanical strength of the component. Nitrogen (N2) at 1200 ° C or less can prevent SiC from oxidizing at 1350 ° C or higher and reacting with SiC, so that SiC decomposes chlorine gas (Cl 2 ) to completely decompose Sic.

Precautions:
1. The sic heating elements is hard and brittle, and is easily broken by severe vibration and impact. Therefore, take extra care when transporting, and take it with care.
2. The length of the silicon carbide rod heating part should be equal to the width of the furnace. If the heat-generating part protrudes into the furnace wall, it is easy to burn the furnace wall.
3. The length of the cold end of the silicon carbide elements should be equal to the thickness of the furnace wall plus the length of the cold end extending out of the furnace wall. Generally, the cold end portion has a length of 50 to 150 mm to cool the cold end portion and the connecting fixture.
4. The inner diameter of the furnace wearing silicon carbide rod should be 1.4 to 1.6 times the outer diameter of the cold end. The furnace hole is too small or the filler in the hole is too tight. At high temperature, the silicon carbon rod is prevented from freely expanding and contracting, resulting in broken rod. . When installed, the silicon carbon rod should be able to rotate 360 degrees freely.
5. The distance between the silicon carbide heating rod and the object to be heated and the furnace wall should be greater than or equal to 3 times the diameter of the heating part. The center distance between the silicon carbide rod and the silicon carbide rod should be not less than 4 times the diameter of the heat generating portion.
