What material is used for the gas burner of tunnel kiln?

Made of high-temperature alloy materials, mainly including the following materials:

1, Cr-Al alloy: Cr-Al alloy has the characteristics of high temperature strength, oxidation resistance and corrosion resistance. , and can maintain stable mechanical and chemical properties at high temperature, so it is often used to make tunnel kiln gas burners.

2. Cr-Ni alloy: Cr-Ni alloy has the characteristics of high temperature strength, corrosion resistance, oxidation resistance and thermal fatigue resistance. It is a common high-temperature alloy material, and is also suitable for manufacturing tunnel kiln gas burners.
