A strip accumulator provides continuous strip supply to the tube mill from non-continuous coils. It temporarily stores strip so that coil changeover and end welding can be completed while the mill continues to run.
This series includes tabletop accumulators, horizontal roller accumulators, and horizontal spiral accumulators. All three types adopt an entry-from-outer and exit-from-center structure, with loop storage methods varying by model.
On the first coil, hydraulically actuated pinching rollers drive the strip from the inlet twist stands onto the accumulation rollers, where it is stored as inner and outer loops. As more strip is fed in, the number of loops and the total storage length increase.
When the loop count reaches the designed value, the pinching roll stops, while powered rollers continue feeding strip into storage until full capacity is reached.
During operation, the powered forming mill passively pulls the strip out through the central spiral roll track. The strip then passes through the outlet de-twist roll stands before entering the forming mill.
The accumulator operates through repeated cycles of fast fill-in, full storage, and strip supply to the tube mill line.
Continuous strip supply during coil changeover.
Entry-from-outer and exit-from-center structure for strip storage and delivery.
Variable or fixed loop storage options depending on the accumulator type.
Large storage capacity for uninterrupted line operation.
Empty and full storage detection, alarming, and remote monitoring.
Heavy-duty mechanical design for long-term operation.
Spiral roll track design intended to reduce strip resistance during pull-out.
The strip accumulator is suitable for tube mill lines that require continuous processing of strip from non-continuous coils. It is installed between the entry section and the forming mill to support coil changeover, end welding, and uninterrupted line operation.
Horizontal spiral accumulators are equipped with centralized chain or individually separate drive, and can operate in stop, high-speed fill-in, synchronized speed, and jog modes. They are suitable for production lines that require controlled strip storage and automatic monitoring.
The accumulator can be applied to production lines processing galvanized strip, bright surface strip, and automotive strip, and can be used in line configurations that communicate with the uncoiler, flattener, and shear & end welder.
The following specifications help determine the suitable accumulator model based on strip width, thickness, required storage capacity, and fill-in speed.
It temporarily stores strip so that the tube mill can keep running while coil changeover or end welding is being completed.
The strip enters from the outer side of the accumulator and exits from the center, which supports continuous storage and delivery.
Variable loop storage allows the stored loop number to change according to the operating condition, while fixed loop storage keeps the number of loops predetermined for the machine design.
The horizontal spiral accumulator supports stop, high-speed fill-in, synchronized speed, and jog modes. It is also equipped with empty and full storage detection, alarming, and remote monitoring.
