LPG Cylinder Equipment

Automatic-grade LPG cylinder annealing furnace with 18-21 KW power, 220V operation, and electric-driven heating for uniform stress relief and metallurgical property restoration in cylinder manufacturing.

Working Principle

<p>The annealing furnace operates by heating welded LPG cylinders to the austenitic transformation temperature (typically 870-920°C for low carbon steel). The cylinders are loaded onto a conveyor or placed on hearth fixtures and transported through the heating zone where electric heating elements or gas burners provide uniform heat. After reaching the soak temperature, the cylinders are held for a specified duration to allow complete transformation, then slowly cooled in a controlled manner to achieve the desired metallurgical properties. Temperature is precisely controlled through PID controllers and zone-based thermocouple monitoring.</p>
