The forming section adopts the principle of rolling forming, gradually forming the strip into a billet tube, and then heating the welding seam through the Kelvin effect and the proximity effect of high-frequency current to make it reach the welding temperature and complete the welding. The scraping device will then cut off the extra burrs created during the welding stage, and the heating tube will go through a water cooling process to reduce the tube temperature to a standard temperature. Next, another round of roller sizing will further shape the size and thickness of the pipe to the desired diameter or size. Finally, the tube will go through the Turks head for square tube production.
Technical process:
Scrolling Up→ Uncoiler→ Shear & End Welding→ Accumulator→ Forming part→ HF Welder → External Burr Removing→ Water Cooling → Sizing→ Flying Saw → Run Out Table →Inspecting→ Packing→ Warehouse
Another name for the rough straightened device is Turks head, it is the final step of sizing section. It is used to shape the round pipe into square or rectangular tube through precisely positioned rollers, and then rough-straighten it. It consists of four four-roller straightening machines, with its head able to revolve and move horizontally. The first 3 turks head are used for round-square shaping and the 4th one is for rough straightening.
