ED Type Silicon Carbide Rod
ED-type silicon carbide rods are mainly made of silicon carbide and feature an equal-diameter structure, meaning that the diameters of the heating part and the cold end are basically the same. The heating part is formed by pressing and sintering high-purity silicon carbide particles through special processes, with a good conductive network being formed inside.
ED-type silicon carbide rods,With their unique performance advantages, are widely used in numerous fields. The following are some of the main application scenarios:
Ceramic Firing
In the production of ceramics, precise temperature control is required in multiple stages from the drying of green bodies to the sintering of finished products. For example, during the firing process of high-grade porcelain, ED-type silicon carbide rods can provide uniform and stable heat, ensuring that the porcelain is heated evenly during the heating process, thus avoiding defects such as cracks and deformations and improving the yield and quality of finished products.
For some special ceramics, such as ceramic cutting tools and ceramic bearings, the requirements for sintering temperature and temperature uniformity are even more stringent. The advantages of the high-temperature performance and temperature uniformity of ED-type silicon carbide rods can fully meet these requirements, helping to enhance the hardness, toughness, and wear resistance of these special ceramics.
Glass Processing
In the glass melting stage, ED-type silicon carbide rods can serve as highly efficient heating elements to quickly heat the glass raw materials to the molten state. Their energy-saving and high-efficiency characteristics help to reduce energy consumption and improve production efficiency.
In the annealing process of glass, ED-type silicon carbide rods can provide a uniform temperature field, effectively eliminating the internal stress of the glass, improving the strength and stability of the glass, and reducing the risk of breakage of glass products during subsequent use.
Metal Heat Treatment
They are used in heat treatment processes such as quenching, tempering, and annealing of metal materials. Taking steel as an example, during the quenching process, ED-type silicon carbide rods can quickly heat the steel to the quenching temperature, and then by precisely controlling the cooling speed, the desired microstructure and properties can be obtained, such as increasing the hardness, strength, and toughness of the steel.
In the heat treatment of non-ferrous metals such as aluminum, copper and their alloys, ED-type silicon carbide rods also play an important role. By providing uniform heating, they can improve the processing performance and mechanical properties of metal materials, meeting the requirements of different application fields for the properties of metal materials.
