In high-temperature industrial fields such as cement, glass, and metal smelting, the precise control of temperature parameters directly determines production efficiency, product qualification rate, and operational safety. Traditional thermocouple protection tubes often suffer from frequent damage and failure due to their inability to withstand extreme temperatures, molten medium erosion, and chemical corrosion. This not only increases equipment maintenance costs and downtime losses but also may lead to production accidents due to temperature measurement deviations. With its unique material advantages, the nitride bonded silicon carbide (Si3N4-bonded SiC) thermocouple protection tube has become the preferred solution for solving temperature measurement problems under harsh working conditions, widely adapting to temperature measurement scenarios in various high-demand industries.
In the rotary kiln, the core equipment of cement production, this protection tube can withstand high temperatures above 1300℃ for a long time, resist the strong scouring of cement clinker particles and the corrosion of acidic flue gas in the kiln, stably protect the built-in thermocouple sensor, and ensure the real-time accuracy of temperature data in key parts such as the kiln cylinder and burning zone, providing reliable data support for the optimization of cement calcination process and energy consumption control. In the glass melting furnace scenario, its excellent resistance to molten glass erosion and thermal stability can effectively avoid the dissolution and cracking of the protection tube, ensure the continuity of temperature monitoring in areas such as the melting pool and channel, and help improve the transparency and uniformity of finished glass products. In the smelting process of metals such as steel, aluminum, and copper, it can resist the high-temperature scouring of molten metal and the erosion of oxidizing and reducing atmospheres in the furnace, adapt to the temperature measurement needs of various equipment such as converters, electric arc furnaces, and continuous casters, and avoid temperature measurement interruptions caused by sensor damage.
In addition to core industry applications, this protection tube can also be used in special high-temperature scenarios such as waste incinerators, ceramic sintering kilns, and chemical high-temperature reaction kettles, adapting to different specifications of thermocouple types. Its core characteristics such as high temperature resistance (up to 1600℃), high mechanical strength, excellent corrosion resistance, and good thermal shock resistance can significantly extend the service life of thermocouples by 3-5 times, greatly reduce equipment maintenance frequency and replacement costs, and improve the continuous operation stability of production lines. Choosing our nitride bonded silicon carbide thermocouple protection tube can not only provide you with a precise and stable temperature measurement experience but also reduce downtime losses with its high reliability, empowering enterprises to achieve efficient, safe, and low-cost production.
