Silicon carbide rod is a non-metallic electric heating element of rod or tube shape made from super-purity hexagonal green silicon carbide as its raw material. After embryo processing, high temperature silicification, and recrystallization it has an operating temperature up to 1450 degC for normal use.
Replace silicon carbide rods as a group to avoid mixing new and old ones together, and keep any unbroken rods for future use.
High Temperature Capability
Silicon carbide rods can withstand temperatures of up to 1600 degrees Celsius without suffering damage or oxidation, making them suitable for industrial processes such as metal smelting and semiconductor production. Furthermore, these rods can also be utilized in laboratory equipment for scientific research or experimental applications.
Silicon carbide heating elements are highly durable and resistant to corrosion from water vapor, toxic gases and metal oxides, significantly shortening their lifespan compared to traditional metallic elements while saving users both time and money in replacement costs in the long run. This reduces frequency of replacements significantly saving both users time and money in replacement expenses over time.
When replacing a silicon carbide rod, it is advisable to save and save only the undamaged one in order to avoid mixing new and old elements when replacing it later on. You can do this by plugging any holes on it; when ready for replacement next time around, plug and reconnect it directly to its power source.
Silicon carbide heaters combine high working temperatures with low resistance and deformation at high temperatures, making them the ideal heating elements for high-performance furnaces. Common applications for silicon carbide heating elements include powder metallurgy, ceramics manufacturing, glass fabrication and semiconductor production as well as laboratories conducting scientific research. Silicon carbide rods may be doped with elements such as nitrogen, phosphorus, gallium or boron for additional conductivity enhancements.
Long Lifespan
Silicon carbide is an extremely durable material capable of withstanding high temperatures, and its resistance to erosion makes it a prime component for extensometers that measure material deformation under stress. Furthermore, its long lifespan reduces replacement frequency and thus production costs for users.
Silicon carbide resists damage from chemicals and volatiles in its environment, such as water vapor, metal oxides and process vapors. Furthermore, its hard surface offers protection from scratches or wear-and-tear.
Silicon carbide produced through sintering technology is extremely strong and durable, which makes it suitable for many different applications such as ceramics, powder metallurgy, glass manufacturing and analytical chemistry. Furthermore, silicon carbide acts as an efficient heating element in kilns, tunnel kilns, muffle furnaces, electric furnaces or tunnel furnaces.
Silicon carbide can withstand high temperatures, providing good heat-conductivity and resistance properties. Unfortunately, due to its hard texture, silicon carbide can be fragile when exposed to vibration or impact and should therefore be handled carefully when transporting and storing. Furthermore, silicon carbide heaters should connect to power supplies with wide voltage-regulating ranges in order to avoid damage while being protected against excessive vibration or impact when operating in high-temperature environments.
High Resistance
Silicon carbide rods possess an extremely high resistance value, generating considerable heat when an electrical current passes through them. This makes them suitable for high-temperature industrial processes such as metal heat treatment, glass production and ceramic manufacturing as well as semiconductor fabrication. Furthermore, their nonlinear resistance characteristic allows precise control over heating temperature control.
Aluminum-coated ends on these rods help prevent them from corrosion in corrosive environments, as well as prevent moisture from reacting with their materials, which could result in resistance values becoming imbalanced and shortening lifespan. As silicon carbide rods are hard and brittle, extra caution must be taken during transportation and installation processes.
These electric heating components can serve as the core electric component in tunnel kilns, roller kilns, glass melting furnaces, vacuum furnaces and other heating devices. Working in conjunction with advanced automated electronic control systems they provide precise constant temperature control as well as curve-type automatic temperature adjustment to meet specific production process requirements and greatly increase production efficiency in industrial kilns and furnaces. Furthermore they may be utilized as chemical processing equipment to heat corrosive and reactive substances.
Hög värmeledningsförmåga
Silicon carbide’s superior thermal conductivity enables it to withstand higher temperatures than metal components, making it ideal for industrial furnaces and other applications that require precise temperature management. This makes achieving uniform heating throughout an area being heated easier, and in turn improves production quality and productivity.
Silicon carbide rods’ hardness and durability reduce abrasion and deformation, and its low thermal expansion coefficient ensures it will not expand under heat or pressure, making it an integral component of extensometers used for material testing.
SiC rods come in an array of styles and designs tailored to the specific needs of various industries. For instance, an LD single-threaded silicon carbide rod serves as an ideal replacement for steel and cast iron heaters used in tunnel kilns, roller kilns, muffle furnaces, glass melting furnaces or muffle furnaces; its lifespan extends up to 1600degC making it well suited for metal heat treatment and ceramic firing applications.
SCR type silicone carbide elements are designed for environments that experience frequent temperature variations, using advanced electronic control systems to maintain constant temperature control and curve-type automatic temperature adjustment. Their counterpart, the GC type is suitable for demanding ceramics, glass and powder metallurgy environments thanks to its robust performance and reliable operation.
