In the industrial scenarios of tunnel kilns and pipeline kilns, the high temperature environment is like a “flame mountain” – equipment components need to withstand long-term roasting above 800 ℃, while also resisting the erosion of oxidizing gases and even acidic gases. Traditional metal materials are prone to softening and deformation in this environment, resulting in a sudden decrease in lifespan. However, the square beam roller rod made of silicon carbide (SiC) material is like a “high-temperature fighter”, relying on its inherent heat resistance gene, becoming the “sea anchor” for stable operation of high-temperature kilns.
The reason why silicon carbide square beam rollers can become the “ace player” in the high-temperature field is due to their unique material properties:
1. Build a self built “thermal barrier”
When the temperature exceeds 1200 ℃, a dense silicon dioxide (SiO ₂) oxide film will spontaneously form on the surface of silicon carbide. This layer of “transparent armor” can not only isolate the direct impact of high temperature on the substrate, but also resist the penetration of acidic gases, achieving “dual protection against high temperature corrosion”.
2. The hotter it gets, the stronger it becomes
Contrary to the characteristic of metal materials becoming soft when exposed to heat, silicon carbide not only maintains its bending strength in the high temperature range of 800 ℃ -1350 ℃, but also shows some enhancement. This “going against the trend” physical characteristic allows the roller bar to remain firm in high temperature environments, avoiding structural collapse caused by softening.
3. Thermal “teleportation master”
The thermal conductivity of silicon carbide is four times that of steel, which can quickly and evenly disperse local heat like a “thermal highway”, avoiding the accumulation of “hot spots” in the kiln. This characteristic not only protects the roller itself, but also maintains the stability of the desulfurization reaction temperature, improving overall efficiency.
Born for industrial high-temperature scenarios
The high temperature resistance of silicon carbide square beam rollers makes them particularly outstanding in high-temperature desulfurization scenarios such as thermal power boilers, steel sintering, and chemical cracking. After adopting this component, enterprises can significantly reduce the frequency of high-temperature shutdown and maintenance, while extending the service life of equipment to several times that of traditional materials, truly achieving “high temperature without shutdown, environmental protection without cooling down”.
As an innovative enterprise specializing in the research and development of silicon carbide ceramic materials, we are well aware of the pain points of equipment under extreme working conditions. Every silicon carbide square beam roller embodies the ultimate exploration of materials science. In the future, we will continue to focus on “high temperature resistance” as the core breakthrough direction, and use the power of technology to safeguard the green defense line of industrial production.
