Silicon nitride and silicon carbide beams have excellent high-temperature flexural strength, creep resistance and oxidation resistance; mainly used in sanitary ceramics, high-voltage electrical porcelain, filters, quartz crucibles; shed plates and fish-shaped plates which are widely used in daily-use ceramic Industry; protection tube is used for temperature measurement in various industries; special-shaped products and burner sleeves are widely used in various kiln and mechanical engineering.
sisic beam has high bearing capacity at high temperature, long-term use without bending deformation.silicon carbide beams works at 1380 C,technical parameters of the cross beam remain unchanged.sisic beam has high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, heat resistance, good thermal shock resistance, good thermal conductivity and high thermal efficiency.sic beams made by reaction bonded silicon carbide are used for the loading structure systems of tunnel kilns, shuttle kilns and many other industrial kilns.silicon carbide beams have higher strength and there are no deformations even in very high temperature.And also this kind of silicon carbide shelves display long operational life. Reaction bonded silicon carbide ceramic beams are the most suitable kiln furniture for sanitarywear and electrical porcelain applications.
Advantages of frame type energy-saving kiln furniture sic beam:
The weight is 30% of the traditional SIC kiln furniture
The load density is 1.4 times as the traditional SIC kiln furniture
The energy consumption is 30% lower than the traditional SIC kiln furniture
The trolley speed is 40% faster than the traditional SIC kiln furniture
