NSiC electric heating sleeve and protective sleeve

In the complex environment of the metallurgical industry, the performance requirements for key equipment are extremely high. Our Nitride bonded silicon carbide (Si₃N₄-bonded SiC) electric heating sleeves and protective sleeves are precisely developed to meet such high demands.

Nitride bonded silicon carbide is a high-performance composite material. It possesses excellent high-temperature resistance, enabling stable operation under high temperatures without significant degradation in material strength. This effectively resists damage to the sleeves caused by high-temperature environments, ensuring the normal operation of equipment during high-temperature metallurgical processes. It also has good thermal shock resistance, capable of withstanding rapid temperature changes and avoiding cracks or damage caused by thermal expansion and contraction. When exposed to molten metals such as aluminum, lead, zinc, and copper, it exhibits outstanding erosion and abrasion resistance. It is not corroded by molten metal solutions and does not contaminate the molten metal, thus ensuring the purity of metallurgical products. Additionally, this material has excellent oxidation resistance, wear resistance, and high flexural strength, resulting in a long service life that helps reduce equipment maintenance and replacement costs.

Our electric heating sleeves feature high heating efficiency, enabling rapid temperature rise and uniform temperature distribution, thereby providing a stable heating environment for metallurgical reactions. The protective sleeves, on the other hand, offer reliable protection for internal equipment and extend the service life of the equipment. Both products are widely used in various metallurgical furnaces, such as aluminum melting furnaces and copper smelting furnaces. Choosing our silicon nitride bonded silicon carbide electric heating sleeves and protective sleeves means opting for a more efficient, stable, and durable metallurgical solution.
