HG127 Tube Mill for diameter 10-150mm within thickness 1-5mm
Summary
The mill is intended for manufacturing of round pipe of Φ20mm-Φ127mm with thickness of 1.5mm–5.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths. Finished product will be of round, square or rectangular pipe.
The technical flow of the production line
Steel Tape → Single-arbor un-coiler → Strip-head Cutter and welder →
Spiral Accumulator → Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame → Cooling unit → Sizing unit and straightener → Flying saw under computer-control → Run-out table → straightening

Five-roll Flattener
2.1 Brief
There are pairs of nipping and sending roller. Flatten rolls are arranged for two top and three below. Nipping and sending is pressured by hydraulic cylinder, flatter roll motor is cogged by worm wheel and worm screw reduced speed, the worm screws in front and one in back can come true be in-phase by sleeve connecting, which can ensure top leveling roll and under leveling roll be parallel, thereby which reach in the intention of flatten.
