I. Summary ERW219steel tubemaking machine is designed to produce welded pipes of OD 89mm(3)-219mm(8 ) and wall thickness 2.3mm-9.0mm, as well as corresponding square and rectangle tube. After we absorbed advanced pipe making technology at home and abroad, our innovative production line and each single unit of the production line are not only economical but also practical. The complete production line adopts ZTF technology developed by our company when producing circle pipe. By means of ZTF technology, the customer shall reduce 60% expense on tooling and improve production effiency and create more economic benefit. II. Basic Technical Information: 1. Products Pipe OD: 89mm-219mm Thickness: 2.3mm-9.0mm Square tube: Max 175mm×175mm, 250mm×150mm Thickness: 2.3mm-7.0mm Length: 6 -12m Length Tolerance : ±3mm 2. Raw Material: Material: Mild steel coil Width: 280mm-700mm Thickness: 2.3mm-9.0mm Coil ID: 510-610mm Coil OD: Max 1800mm Coil Weight: 8 t 3. Tube mill Production Speed : 10-50 m/min Direction : From left to right or decided by your side. Electricity Input Power : 1500 kw Line Area : 100m(length) ×10m (width) Tube Bottom Passline (Above floor level) 850 mm III. Flow Chart and Technology Description 1. Flow ChartUncoiling→Shear & butt welding→Cage loop→Forming →HF welding →Removing & outsied Bead →Cooling →Sizing →Cuttingoff → Conveying →Downloading → Packing →Warehousing2. Technology Description First, the coil of strip is lifted to coil car by overhead crane, the coil car with coil of steel strip is carried to uncoiler, then coil car runs its oil cylinder in vertical direction to make the center of steel strip aim at center of cone of uncoiler, which can hold the coil of strip steel; When coil is held, coil car will return to preparing position for the next time. Secondly, drag roll of coil opener falls and impacts into steel coil, the cone of uncoiler circumrotates, at the same time shovel of coil end opener uplifts and presses close to steel coil. The end of strip steel is scooped up through oil cylinder work, as the uncoiler cone to-and fro circumrotates slightly, which will level the strip steel head. The cone continues to round; strip steel is carried to flattener. Withdrawal rolls chimp strip steel head; gyro-withdrawal rolls carry strip steel into five-roll flattener, which will flat strip steel by to-and-fro moving. Strip steel flatted is carried into shear weld, the head and trial of strip steel is sheared to align, then is carried to weld platform and is weld via gas protection weld, strip steel weld is carried to accumulator for reserve. Thus, the preparation for forming and sizing has been done Forming and Sizing stage: Steel strip be disposable is rolled to corresponding specification tube blank (preform), then tube blank brim is heated to welding temperature (1130-1350) unitized Kelvin skin effect and proximity effect of high frequency electric current, then will be squeezed and weld by squeezing roll, thereby which form close entry tube blank. A guide roll stand fixed in front of squeezing roll is used to guide weld seam and control open-mouth angle, consequently made tube blank into squeezed roll for welding. After squeezing roll , Bead trimmer rack scrape the weld bead and Polishing stand will burnish the weld seam , then the welding pipe will enter into cooling part and then sizing part. Round pipe is directly sized to eligible size, after which is straightened and is carried into cut-off machine. The pipe will be cut into length by Cut-to-length machine , go through rollway platform and will be carried to platform, and then be checked, marked, separated, packed and warehousing.
