Steel Drum Production Line
The steel drum production line is a fully automated system covering drum making, bottom and lid formation, spray painting, testing, and more. The high-speed seam welding machine uses a three-part power source: phase secondary rectifier, three-phase medium frequency inverter DC, and three-phase variable frequency AC, ensuring compatibility with various material specifications. Hard specifications in welding ensure stable and durable equipment.
Technical Solution
Complex pressing technology in Front Equipment saves 3-4% steel per 55-gallon drum.
7-layer circle rolling technology (core tech) used in Middle Equipment.
High-pressure airless painting and fuel heating in Post Production Equipment.
Drums meet UN Class 1 standard for Sea Transport of Dangerous Goods.
- Capacity config: 2-10 drums/min
- Operators: around 11 people

Production Results
Welding Method:
This equipment uses a roll seam welding method, with electrodes in the form of cylindrical rollers. The width of the electrode is greater than the overlapping section of the steel plate, allowing control over the thickness of the joint. During the welding process, a higher electrode pressure and continuous welding current are applied. By controlling welding parameters such as electrode pressure, welding current, and welding time, stable welding quality can be achieved. The machine is capable of performing the seam welding process on longitudinal seams of metal drums with diameters ranging from 516mm (for conical drums) to 571.5mm.
