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.
