High-temperature silicon carbide rod heating element

       Dengfeng City Chuangwei Carbide Products Co., Ltd. is located in the Sanlizhuang High-Tech Industrial Park in Dengfeng City, where National Highway 207, Provincial Highway Yu 03, and the Zhengshaoluo Expressway converge. It is 20 kilometers from the famous Shaolin Temple on Mount Song, 68 kilometers from the provincial capital Zhengzhou, and 70 kilometers west from the ancient capital of Luoyang, which served as the capital for nine dynasties. With convenient transportation, beautiful scenery, and a pleasant environment, the company is primarily engaged in the research and production of molybdenum disilicide heating elements (silicon molybdenum rods), custom-shaped silicon molybdenum rods (1800-degree silicon molybdenum rods), silicon carbide heating elements (silicon carbon rods), silicon nitride-bonded silicon carbide radiation tubes, thermocouple protection tubes, riser tubes, and high-temperature tungsten and molybdenum products, as well as the research and development of production technologies in related fields. Continuously improving product quality, the company has accumulated extensive manufacturing experience and technology, utilizing advanced process equipment, a comprehensive ISO9001 quality management system, and scientific management models to provide high-quality products and services to domestic and international clients. We sincerely welcome you to visit Mount Song and Shaolin Temple to guide our work!

Silicon carbon rod heating tubes use green, high-purity silicon carbide as the main raw material, processed into blanks, and formed through high-temperature silicification and recrystallization. They are rod-shaped non-metallic high-temperature electric heating elements. Domestic silicon carbon rod enterprises use similar formulas and production processes, with the maximum operating temperature consistently unable to exceed 1520 degrees Celsius. Compared to traditional metal elements like heating wires, these elements offer advantages such as high operating temperature, corrosion resistance, long lifespan, minimal deformation, multiple models, easy installation, and simple maintenance. They are widely used in various high-temperature manufacturing fields, including magnetic materials, powder metallurgy, ceramics, glass, metallurgy, and molds. Due to environmental requirements, silicon carbon rods now employ a new production process for hot and cold ends, featuring an excellent hot-to-cold end resistance ratio. This avoids the damage to furnace bodies caused by excessive resistance temperature at the cold end, which was an issue with previous production processes.

One of the silicon carbon rod specifications, the gate-type silicon carbon rod, is a large-spacing element with a center distance of over 180mm. The difference between it and the U-type element lies in the heating section. The U-type element has a vertical hot end as the heating section, while the gate-type silicon carbon rod has a horizontal heating section (the heating length is equivalent to its center distance). Due to the large spacing of gate-type rods, a specialized welding furnace is required during welding, and only 1-5 rods can be welded at a time, resulting in very low production efficiency. Therefore, gate-type rods are much more expensive than U-type rods.
