Silicon carbide furnace tube Its application scope is extremely broad. Before using it, we definitely need to understand the advantages of silicon carbide furnace tubes so that we can make better use of them. If you’re interested in this topic, let’s take a look together—I hope it will be helpful to those who are concerned about it.
Silicon carbide furnace tubes are widely used across various industries, which clearly demonstrates their broad range of applications. Simply put, silicon carbide furnace tubes are made from a hard material with a Mohs hardness of around 9—making it the second hardest non-metallic material after diamond. Moreover, these tubes exhibit high strength at room temperature and nearly retain their original strength and hardness even when exposed to high temperatures ranging from 1,200 to 1,400°C. Depending on the operating atmosphere, they can safely be used at temperatures as high as 1,650 to 1,750°C. When in use, this product has a low thermal expansion coefficient and a thermal conductivity that surpasses that of other silicon carbide products. It is less prone to thermal stress, boasts excellent thermal shock resistance, and enjoys a long service life. Additionally, it exhibits outstanding resistance to high-temperature creep, corrosion, extreme cold and heat, and oxidation. It is also easy to fabricate into products with high dimensional accuracy and meeting stringent requirements. Today, silicon carbide furnace tubes are extensively employed in industries such as steel, nonferrous metals, chemical engineering, and construction materials, offering energy-saving, environmentally friendly benefits and helping to reduce costs. Furthermore, silicon carbide furnace tubes possess characteristics such as corrosion resistance, high-temperature tolerance, high strength, excellent thermal conductivity, and superior impact resistance. As a result, they can be utilized in a variety of applications—including furnace linings, high-temperature furnace components, plates, lining boards, supports, and buckling elements.
Silicon carbide furnace tubes are strong covalent compounds, with the silicon-carbon bond type accounting for only about 12%. As a result, they also exhibit excellent mechanical properties, superior oxidation resistance, high wear resistance, and a low coefficient of friction. Silicon carbide furnace tube It exhibits high-temperature strength during use. While the strength of conventional ceramic materials drops significantly at temperatures between 1,200 and 1,400 degrees Celsius, silicon carbide maintains a relatively high flexural strength of 500 to 600 megapascals even at 1,400 degrees Celsius. As a result, its operating temperature can reach as high as 1,600 to 1,700 degrees Celsius. Moreover, this material is a compound with strong covalent bonds, in which the proportion of silicon-carbon bonds is only about 12%. Consequently, it also boasts excellent mechanical properties, outstanding oxidation resistance, high wear resistance, and a low coefficient of friction. Of course, its most distinctive feature is its exceptional high-temperature strength. Whereas the strength of conventional ceramic materials declines dramatically at temperatures between 1,200 and 1,400 degrees Celsius, the flexural strength of silicon carbide furnace tubes remains at a high level—between 500 and 600 megapascals—even at 1,400 degrees Celsius. Thus, its operating temperature can extend up to 1,600 to 1,700 degrees Celsius. If there’s anything you’re still unclear about, feel free to reach out to our customer service representatives here.
