In the flames leaping in high-temperature environments and on the temperature curve of metal heat treatment, a new industrial “fire control system” is reshaping high-temperature manufacturing processes – the silicon carbide nozzle, with its precise control ability and excellent weather resistance, has become the core component for upgrading modern industrial kilns.
The working principle of a silicon carbide nozzle is that fuel and combustion air mix through a special internal flow channel, forming stable combustion at the nozzle outlet. By adjusting parameters such as channel angle and aperture, the flame shape can be precisely controlled – whether it is a short and concentrated “puncture type” flame or a flat and diffused “blanket like” flame, it can be achieved as needed.
In the extreme test at 1350 ℃, the oxidation weight gain of the silicon carbide nozzle after continuous operation for 3000 hours was only 0.8mg/cm ², which was 72% lower than that of traditional corundum material. This super strong antioxidant property originates from the spontaneously formed silica protective layer on its surface, which forms a dynamic equilibrium redox cycle at high temperatures.
At the same time, in the face of high-speed airflow erosion, acidic gas corrosion, or metal slag splashing, silicon carbide material exhibits extremely strong resistance and can adapt to different harsh scenarios.
From millennium kiln fires to smart factories, humans have always pursued precise control over flames. The silicon carbide nozzle provides a more reliable and intelligent combustion solution for high-temperature industries through material breakthroughs and design innovations. In the future, with the deep integration of manufacturing processes and digital technology, this “fire control technique” will continue to promote the advancement of industrial heat treatment technology towards high efficiency, green, and precision.
