Product Description


Description:

DFS150 (150×150mm) direct forming to square pipe mill/tube mill is used to produce square pipe of 70×70mm-150×150mm and 1.5mm-6.0mm in wall thickness directly, from square or rectangular to square or rectangular pipe directly.,

LW600(150×150mm)  Direct Forming to Square Pipe Mill LW600(150×150mm)  Direct Forming to Square Pipe Mill

Direct square to square forming tube mill advantage:

1. Lower production cost: 5% raw material saving
2. Very Precise control of the corner radius
3. Frequent production changes without a roll change: possibility to produce small lots of final products
4. Mature design
5. Very Fast changeover
6. Reduced investment: no requirement for different types of rolls and additional floor space for roll storage
7. Very High automation level: minimized operator tuning

NO.Comparative ItemAutomatic Changing Tube Sizes TechnologySemi-automatic Changing Tube Sizes TechnologyManual Changing Tube Sizes Technology
1Roller consumptionOne set of roller for all pipe sizesChange roller by grades,change of rollers in welding part, fin pass and fine sizing is required.Share rollers in breakdown, each size requires one set of roller in other parts.
2Changing size methodServo motor control, touch screen computer setting, full automatic size changing, ready by one button.Part of the frames is adjusted electrically, measuring while adjusting at the mean time. Disassembly of shaft system is required for other frames.Manually disassembly spacer and rollers.
3Changing size timeFast size changing,can be finished within as little as 30 minutes, meet the fast delivery requirement.Slow size changing, needs at least 4 hours, which may affect the delivery.Slow size changing, normally needs at least 1-2 days, which may affect the delivery.
4Changing size intensityLow labour intensity, needs only 2 staff.High labour intensity, needs at least 4 staff.High labour intensity, needs 8 staff.
5Welded pipe qualityStable quality, high tube precision.Quality decrease year by year, which will increase the difficulty of tube quality control.Quality decrease year by year, which will increase the difficulty of tube quality control.
6Service lifeFree of disassemble, long service life.Needs frequent disassemble, which will affect equipment accuracy, short service life.Needs frequent disassemble, which will affect equipment accuracy, short service life.
7Equipment consumptionStable and reliable, low defect rate and equipment consumption.Defect rate increase year by year, which will increase the quantity of spare parts.Defect rate increase year by year, which will increase the quantity of spare parts.
8Electricity consumption and maintenanceAdopts AC frequency variable motor, single drive, which has fine synchronization, low electricity consumption and low maintenance cost.Adopts high-power DC motor, centralized transmission, which has high electricity consumption and high maintenance cost.Adopts high-power DC motor, centralized transmission, which has high electricity consumption and high maintenance cost.
9Equipment investmentSave roller, low equipment investment.Reduce part of the roller consumption.Huge roller investment.


Remark: The mill can be designed according to customers’ requirement accordingly
