A. The helix is a key device for accumulator. Its design and manufacture error directly and seriously affect the resistance of the strip from the accumulator. The spiral path consists of multiple rollers to form an approximate a spiral plane, and the central space positions of the arc surfaces formed by each roller are different, so that the outer bus bars of the rollers are completely in contact with the steel strip, and the steel strip is not plastically deformed.

B. The pinch device works smoothly, and the material storage table is large;

C. The electric system adopts full digital UK EUROTHERM DC governor, which is easy to operate, stable to operate and low failure rate.

D. The mill traction load is small, saves the power, improves the roll life.
