Matter Needing Attention
1, silicon carbide pipe texture is hard and brittle, thread with limited elasticity, installation and disassembly should be fully careful attention,
2, life and the use of temperature is very much related, generally in 1300ºC±50ºC can run 1500 working hours.
3, the heated material can not contain too much water, otherwise it will affect the life of the silicon carbon tube
4, silicon carbon tube is not suitable for working in a protective atmosphere, such as hydrogen. Thus affect the life of silicon carbide tube.
5the selection of the surface load of the silicon carbon tube changes with the temperature, and the selection of the appropriate heating power can extend the life of the silicon carbon tube.
6, the silicon carbide tube should be cleaned between the internal and external furnace tubes before installation. Remove the debris between the threads of the silicon carbide pipe or that can cause short circuit, the conductive clip connection sheet should be tightly tightened, and the insulation sheet should be reliably insulated.
7, the installation can be electric oven, long-term need not use before also must oven,
8, spare silicon carbon tube should be placed in a dry, no atmosphere erosion place, to prevent aluminized end delixing.
