U Type Silicon Carbide Rod

U-shaped silicon heating element is manufactured by taking two carefully-matched SiC rods and welding a thickened silicon carbide bridge. This element provides for wiring both tail ends from one side of the furnace. The tail ends of the cold ends are metallized with aluminum, which can provide a low-resistance contact surface to the aluminum connection straps and clamps.

Since U-shaped silicon heating element is composed of two ED silicon heating elements sharing a cold end, it can be connected by the power cord at one end of the furnace. The surface temperature of heating part is 1500. It is mainly used in kilns with high furnace temperature and high temperature uniformity. Its characteristics are electricity saving and long service life.

In addition, a furnace with an energy saving structure can be built because the number of heating element holes on the furnace can be reduced compared with the U types. These elements are widely used as high-temperature heat sources for electric furnaces and for the firing of ceramic capacitors, ferrites and other electronic components.

The Silicon Carbide Rod is a premium-grade non-metallic heating element widely used in high-temperature industrial furnaces and kilns. Manufactured from high-purity recrystallized silicon carbide, this Silicon Carbide Rod offers exceptional oxidation resistance, stable electrical conductivity, and a maximum operating temperature reaching up to 1600°C. Unlike traditional metal heating wires, the Silicon Carbide Rod does not soften or deform under prolonged heat exposure, making it ideal for applications in ceramics, glass melting, metallurgy, and electronic component sintering. Each Silicon Carbide Rod is precisely engineered to deliver uniform heat distribution, reducing hot spots and extending service life even under thermal cycling conditions.

One of the key advantages of the Silicon Carbide Rod is its rapid thermal response and energy efficiency. Whether used in laboratory testing furnaces or large-scale industrial production lines, the Silicon Carbide Rod ensures quick start-up times and precise temperature control. Its unique resistance-temperature characteristic allows for stable performance over a wide range of voltages. To maximize lifespan, users should avoid rapid cooling or overheating beyond rated limits. With proper aging treatment and periodic resistance matching, a single Silicon Carbide Rod can operate reliably for thousands of hours. Available in various diameters, lengths, and cold-end configurations (including two-zone, three-zone, and U-shaped designs), our Silicon Carbide Rod fits seamlessly into both new furnace builds and retrofit projects.

For maintenance and replacement, we recommend always using Silicon Carbide Rod elements from the same batch to ensure balanced resistance. Dust and surface contamination can be cleaned gently with compressed air. When ordering, please specify your furnace’s voltage, required resistance, and mounting center distance. Backed by strict quality control and fast global shipping, our Silicon Carbide Rod is the trusted choice for engineers seeking durability and thermal stability.
