Industrial kilns require channels resistant to thermal stress:
Heat Resistance:
Refractory-lined channels (ASTM A299) maintain strength at 600°C, supporting kiln hoods in Vietnam's brick factories.
Thermal Fatigue:
Low-alloy channels (1.25Cr-0.5Mo) withstand 500+ heating/cooling cycles, outperforming carbon steel by 300% in India's kilns.
Corrosion Resistance:
Aluminized channels resist flue gas corrosion, extending service life from 2 to 5 years in China's Shanxi brickworks.
