Features and Applications of Silicon Carbide Furnace Tubes
Release time:
2022-05-20
Silicon carbide boasts characteristics such as high input impedance, low noise, and excellent linearity. It is one of the rapidly developing silicon carbide components that has been among the first to achieve commercialization. It does not suffer from reliability issues caused by gate oxide defects nor is it constrained by low carrier mobility; its unipolar operating characteristics ensure outstanding high-frequency performance.
In addition, silicon carbide junction structures exhibit superior stability and reliability at high temperatures; consequently, their threshold voltages are typically negative, making them normally-on devices—conditions that are highly unfavorable for power electronics applications and incompatible with today’s commonly used gate-drive circuits. By introducing trench injection device technology, we have developed normally-off enhanced-mode devices. However, enhanced-mode devices often come at the cost of slightly degraded forward on-state resistance characteristics. As a result, normally-on (depletion-mode) devices are easier to implement for achieving higher power density and current-carrying capacity, whereas depletion-mode devices can achieve the desired operating state through cascading.
Silicon carbide furnace tube The primary application areas for this engineered material include the solar power industry, the semiconductor industry, and the piezoelectric crystal industry. It is used for cutting 3- to 12-inch single-crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystals, and more. Other applications encompass lightning rods, circuit components, high-temperature applications, ultraviolet detectors, construction materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heat-generating parts, nuclear fuel, gemstones, steel, armor, catalysts, and more. The distinctive feature of silicon carbide furnace tubes lies in their extensive use across so many diverse industries.
Silicon carbide furnace tubes exhibit excellent properties such as high-temperature resistance, wear resistance, corrosion resistance, high hardness, high strength, high thermal conductivity, superior thermal shock resistance, and good oxidation resistance. They are used in a variety of heat-treatment electric furnaces and metallurgical sintering furnaces. However, in industries such as medium-frequency furnace forging, nonferrous metal smelting, and chemical processing, the heavy weight of the furnace tubes necessitates transportation after production. Since there is currently insufficient handling equipment available, it is essential to improve the efficiency of uniformly transporting these furnace tubes.
It features excellent thermal conductivity and has extremely thin tube walls—just a few millimeters thick—enabling it to respond very sensitively to changes in product temperature. It is corrosion-resistant, does not dissolve at high temperatures, and ensures that the molten metal remains free of contamination. It can be used to melt alloys rich in sodium and strontium. The product’s surface remains free of slag buildup, making maintenance exceptionally simple. It boasts exceptional high-temperature resistance up to 1600°C and strong thermal shock resistance. The product exhibits high hardness and is highly resistant to breakage. It offers excellent value for money and has a service life of over six months.
The silicon carbide furnace tubes to be produced will be purchased. Silicon carbide furnace tube Place it into the tube groove set at the front end of the weight plate. The buckle connection secures the furnace tube within the groove, ensuring a firm hold and preventing damage. The performance characteristics of the silicon carbide furnace tube are as described above.
