Silicon Carbide Heating Rods Description

Silicon carbide heating rod is a high-temperature nonmetal heating elements which are processed by silicon carbide. Comparing to other metal elements, silicon carbide heating element has many advances such as high working temperature, oxidation resistance, longer life, and corrosion resistance. 

The cold ends are impregnated with silicon metal - referred to as one piece, and low resistance cold ends which are furnace welded to the hot zone - referred to as a three-piece or LRE (Low Resistance End) type. This lower electrical resistance cold end causes them to operate at a lower temperature. The extremities of the elements are metalized with aluminum to provide a low resistance contact surface to which the electrical connections are made using braided aluminum straps.

FAQs

Q1. What is an Equal Diameter Silicon Carbide (SiC) Heating Rod?

An equal diameter silicon carbide heating rod is a non-metallic, high-temperature resistance heating element manufactured from high-purity SiC. The diameter remains uniform along the entire effective heating zone, ensuring stable structure and even heat distribution.

Q2. What is the difference between equal diameter and variable diameter SiC heating rods?

· Equal Diameter Type

Uniform diameter in the heating zone

More even temperature distribution

Simple structure and easy installation

· Variable Diameter Type

Different diameters at hot and cold ends

Designed for specific electrical or space requirements

Equal diameter SiC heating rods are widely used in standard industrial furnaces where temperature uniformity is critical.

Q3. What is the maximum operating temperature?

· Maximum continuous operating temperature: up to 1600°C

· Short-term maximum temperature: up to 1650°C

Actual operating limits depend on furnace design, atmosphere, and power control.
