Sic Silicon Carbide Ceramic Square Tube  Pipe Beam

Sic Beam Feature : 

Compared with other metal electric heating elements, it has the following unique advantages:

1. Strong acid resistance and oxidation resistance;

2. The surface load density is larger than the metal heating element, the heating is faster, and the thermal efficiency is higher.

3. Good heat and cooling resistance, small linear expansion coefficient;

4. High thermal conductivity;

5. High temperature, long life, normal air atmosphere, rod surface temperature can reach 1600℃, continuous service life can reach more than 2000h;

6. Easy installation and replacement;

7. A wide range of materials.

Sic Beams Application:

SiC beam is oxidation-resistant, high-strength, and will not deform after long-term use. It is a load-bearing support for shuttle kilns, double-layer kilns and other industrial kilns. It is widely used in various industrial furnaces, desulfurization equipment, large-scale boilers and other mechanical equipment and ceramics, machinery, metallurgy, electronics, chemical industry, petroleum, steel and other fields.

Packing & Shippment :

CS’s Silicon Carbide Products are carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.              

Use/Maintenance Methods :

1, silicon carbide tube texture hard and brittle, thread with limited elasticity, installation and disassembly should be fully careful attention, so as not to break, damage. In any case, it should be guaranteed to expand and contract freely, and the existence of mechanical stress should be avoided.

 2.Silicon carbon tube aging, life and the use of temperature is very close, generally at 1300℃±50℃ can run 1500 hours or so. 

3, the heating can not contain too high moisture, otherwise it will affect the life of silicon carbon tube, can be dried and then heated. 

4, silicon carbon tube is not suitable for working in a protective atmosphere, such as hydrogen. Carbon monoxide will also free the carbon in the case of insufficient oxygen supply, thus affecting the life of the SIC tube. 

5, the selection of silicon carbon tube surface load varies with the temperature, the working temperature at 1300℃ allows 6w/cm2, and the working temperature at 1000℃ can allow 30 w/cm2, choose the appropriate heating power can extend the life of silicon carbon tube. 6. Clean the inner and outer furnace tubes before installing the silicon carbon tube. Remove the sundry between the silicon carbide pipe thread strips or can cause short circuit, the conductive clip connecting piece should be rotated tightly, and the insulation piece should be reliably insulated. 

7, the installation can be energized oven, starting from low temperature and low power for 8 hours, the oven must be used for a long time before not using, especially in the southern humid areas. 8. The spare silicon carbon tube should be placed in a dry place without atmospheric erosion to prevent the delidification of the aluminum plating end.

Customize Requirements: 

Pipe diameter, length of heating end, length of cold end, total length, resistance, service temperature need to be provided 2: link mode and series mode can be provided in detail.
