About Silicon Carbide Tube
Silicon carbide tube has high strength, high hardness, good wear resistance, high temperature resistance, corrosion resistance, good thermal shock resistance, high thermal conductivity, good oxidation resistance and other superior functions. Mainly used in intermediate frequency casting, various heat treatment electric furnaces, metallurgy, chemical industry, non-ferrous metal processing and other industries. Silicon carbide protective tube is widely used in metallurgical sintering furnace and intermediate frequency heating melting and casting furnace, and its length can be customized according to the actual needs of the site;
What are the characteristics of silicon carbide tubes?
1. Silicon carbide tube has high temperature resistance and fast heat conduction;
2. The silicon carbide tube also has the characteristics of corrosion resistance. It is equipped with a special high temperature resistant insulating sleeve, which can effectively avoid the corrosion of the electric heating element (including silicon carbon rod, electric furnace wire, etc.) by the metal solution;
3. At the same time, the silicon carbide tube also has the advantages of high strength, high hardness, good wear resistance, good thermal shock resistance, high thermal conductivity and good oxidation resistance;
What are the main uses of silicon carbide?
1. Silicon carbide tubes are used as rollers, mainly used in roller kilns, and are mostly used for the production of architectural porcelain;
2. Silicon carbide tubes are used as storage tubes, mainly for electronic components, mainly using the high temperature resistance and corrosion resistance of silicon carbide tubes;
3. There is also a silicon carbide pipe used as a lining, mainly used for mine pipelines, etc., using the wear resistance of silicon carbide pipes;
4. Silicon carbide tubes can also be used as radiant tubes, which are mainly used to adjust the incineration ratio of incineration gas and combustion-supporting air, and control the O2% content in the incineration waste gas below 2%. The chemical effect will cause the radiant tube to be damaged by corrosion;
Shape forming of Silicon Carbide Tubing
The resulting pasty mixture may be compacted and shaped either by extrusion or by cold isostatic pressing.
Extrusion consists in forcing the pasty mixture through a die with an opening. Silicon carbide tubes are produced through extrusion. The properties in the extrusion direction differ from the properties in other directions.
Cold isostatic pressing is the powder compaction method conducted at room temperature, and it involves applying pressure from multiple directions through a liquid medium surrounding the compacted part. A flexible mold immersed in a pressurized liquid medium is used. Materials with a uniform anisotropic structure are prepared using an isostatic pressing method. The materials used to produce silicon carbide plates and blocks are manufactured by cold isostatic pressing.
Silicon Carbide Tubing Properties
· High hardness comparable to a diamond.
· Extremely wear and abrasion resistance.
· High-flexural strength at room or high temperature.
· Excellent corrosion resistance.
· High-temperature resistance.
· Excellent thermal shock resistance due to its low thermal expansion and high thermal conductivity.

They are widely praised by customers for their excellent quality and good service. The company always adheres to the product concept of "quality first" and has a deep understanding of customer needs. The company has been committed to the research and development and production of high-performance polyurethane elastomer molds for many years, and solves various design and production problems of polyurethane elastic molds for isostatic pressing users. The company has mature production and processing technology and a complete set of experimental equipment for mold elastomer analysis. In order to ensure the excellent impact resistance, abrasion resistance, cutting, tear resistance and clarity of the product and excellent dimensional stability. Its products are widely used in magnetic materials, ceramics, cemented carbide, high temperature refractory materials, rare earth permanent magnets, carbon materials, rare metal powders and other industries.
Compare to traditional rubber cold isostatic pressing bags, the polyurethane CIP bags have significant advantages. As a new polymer material, polyurethane products feature smooth surface, wearing-resistant, anti-fatigue, low deformation rate. The surface of pressed products with polyurethane bags is much smoother than that pressed with rubber bags, thus it possesses better looks and less postprocessing is required. It’s an ideal tool for powder material forming by press process, which can help a company reduce cost and increase efficiency.
