Product Description

The silicon carbide tube has superior properties such as high strength, high hardness, good wear resistance, high temperature resistance, corrosion resistance, good thermal and shock resistance, high thermal conductivity and good oxidation resistance. Mainly used in medium frequency forging, various heat treatment electric furnaces, metallurgy, chemical industry, non-ferrous metal smelting and other industries. Widely used in metallurgical sintering furnaces and medium frequency heating forging furnaces. Length can be designed

Silicon Carbide Pipe is made of silicon carbide as the main raw material, adding a variety of chemical wear-resistant raw materials and anti-oxidant, effectively improving the wear resistance of the product, using SiO2 micro powder as the high-temperature bonding phase, a high-performance silicon carbide products by high-temperature firing.

Silicon carbide tube has the advantages of high strength, high hardness, good wear resistance, high temperature resistance, corrosion resistance, good thermal shock resistance, high thermal conductivity and good oxidation resistance.

Installation Instructions

 

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.
