Direct Square to Square ERW Tube Mill Production Line adopts the most advanced roll forming technology: multi-point bending method and full-automatic roller adjustment system for precise positioning, it’s the newest direct square & rectangular pipe forming mill production line.
The whole mill could be adjusted by motors, one set of roller only installed on machine can cover different sizes, no need to change rollers or spacers, only 2 hours minor adjustment instead of 1-2 days changing and adjustment. Improving further to on- key reset auto roll adjusting type either with encoder or with more precise servo system, we can shorten it further to 20 minutes by extracting the parameters saved
1.1 Advantages:
1) High efficiency: saving roller change and adjustment time, saving significant cost of different rollers, also saving great labor force and time of roller change and maintenance (only 3 workers needed for whole automation production line);
2) High performance: reducing the forming steps, saving steel coils consumption since the width of steel strip required is 2.4-3% narrower than standard round to square, also occupying smaller production line space. Further more avoiding the axial force and side abrasion, reducing production power consumption, also forming better outer edges & smaller inner arc for the cross section, and flatter brims, improved outlooks;
3) High automation: adopts the most advanced PLC control technology and digital control technology, as well as data recording and storage system, combining one-key auto roll adjusting;
