H-Type High-Temperature Silicon Carbide Rod for High-Temperature Furnace

The H-type high-temperature silicon carbide rod is a key heating element specifically designed for high-temperature kilns. Made from high-density silicon carbide as the core raw material, it undergoes precision molding and high-temperature sintering processes. Its unique "H"-shaped structure makes it an ideal choice for high-temperature conditions ranging from 1200-1650℃. Its design is not merely a matter of form innovation, but a precise optimization based on thermal principles—the parallel "H" structure of the two rods significantly widens the heating surface, allowing for more uniform heat radiation. Combined with the thickened cold ends, it reduces temperature loss at the wiring points and improves current conduction stability.

In terms of high-temperature performance, this silicon carbide rod demonstrates formidable strength. It can withstand long-term operating temperatures up to 1450℃ and short-term extreme temperatures up to 1650℃. Even under the complex conditions of frequent kiln start-ups and shutdowns, it maintains structural stability without deformation or breakage. The application of a composite refractory coating not only enhances oxidation resistance but also effectively slows down aging at high temperatures, significantly reducing equipment maintenance and replacement costs.

In terms of installation and adaptability, it offers significant flexibility. Supporting series, parallel, or star connections, it can be freely combined according to the power requirements of the kiln, precisely matching various types of kilns, including pusher kilns, tunnel kilns, and box kilns. The cold end length can be customized to fit kiln walls of different thicknesses. Wiring is convenient, requiring no complex debugging before use.

From sintering of new energy materials to advanced ceramic processing, from heat treatment of electronic components to calcination of refractory materials, the H-type high-temperature silicon carbide rod provides continuous and reliable thermal support for various high-temperature kilns with stable heating efficiency, uniform temperature field control, and long service life. It helps companies improve product yield and production efficiency, becoming a trusted choice in the field of industrial high-temperature heating.
