Horizontal Steel Strip Accumulator for ERW Tube Mills

A horizontal steel strip accumulator holds a reserve of strip at the entry to an ERW tube mill. While the entry section stops to join the end of one coil to the next, the downstream mill draws strip from this reserve. Continued operation depends on sufficient usable storage for the actual joining cycle. Position in the entry section The process sequence is uncoiler → shear and butt welder → strip accumulator → forming section. The entry welder joins successive coil ends before forming. This is separate from the high-frequency welding operation that produces the tube's longitudinal seam. Match storage and refill to the line Usable stored length, mill consumption and strip-joining time need to be reviewed together. After joining, the entry section must replenish the reserve while supplying the running mill. The required feeding rate therefore depends on both strip consumption and the time available to refill. Floor space or storage diameter alone does not establish capacity. Strip width…
