Core Function: 
As a core heating element in industrial heat treatment furnaces, the straight-tube design enables efficient heat radiation. It completely seals the combustion process within the tube, effectively isolating combustion products from the furnace atmosphere to ensure process purity and workpiece quality, while significantly improving thermal efficiency and operational safety.

Application Fields：
· Continuous Annealing Lines (CAL)
· Hot-dip Galvanizing Lines (CGL)
· Heat Treatment of Castings
· General Industrial Furnace Heating Systems

Key Performance Parameters：
· Design: Straight-tube structure for easy installation and maintenance
· Main Materials: Heat-resistant alloys (e.g., RA330, 2535, 314)
· Operating Temperature: 850°C – 1150°C
· Key Performance: Good heat transfer efficiency, resistance to high-temperature oxidation and carburization
· Service Life: 2 – 10 Years (Depending on operating temperature, furnace atmosphere, and combustion media)
