6. Total power supplied for the line: 160KW

B. Production line process

Raw Material(Belt Steel Roll) → loading → cutting and Butt welding → cage-shape storing chamber → feeding and forming → high frequency welding → cleaning → cooling → setting the diameter and straightening → cutting with flying saw → Transporting to the roller transportation belt and upturning → transition shelf and collection basket → inspection → registration to the chamber

4. Forming and Setting Diameter Unit

(1) Structure: ensemble bed, amass drive

(2) Sequence for fixing the unit:

Forming segment: feeding → seven rollers for straightening → 1 horizontal → 1 vertical → 2 horizontal → 2 vertical → 3 horizontal → 3 vertical → 4 horizontal → 4 vertical → 5 horizontal → 5 vertical → 6 horizontal → 6 vertical → 7 horizontal →7 vertical

Welding segment: Direction guidance → extruding and pressing → Welding → planning the welding → polishing → cooling

Setting the diameter segment: 1 vertical → 1 horizontal → 2 vertical → 2 horizontal → 3 vertical → 3 horizontal → 4 vertical → 4 horizontal → 5 vertical → 5 horizontal → 6 vertical → 6 horizontal → firstly straightening
