Torque tube Manufacturing of:

Rectangular tube, that is, rectangular tube. Rectangular tube is a kind of hollow long steel, also called flat tube, flat square tube or square flat tube (literally). When the bending and torsional strength are the same, the weight is light, so it is generally used to manufacture mechanical parts and engineering structures.

Hot rolled rectangular tubes, continuous casting billets and blooming plates are used as raw materials, and then pass through the heating furnace, even when high-pressure water is used to clean up the surface phosphorus, and then use the roughing mill, on the rectangular tubes at the head and tail of the roughing mill, and then on the pipes, and then fed to the finishing mill for computer controlled precision rolling. After the square tube is cooled by laminar flow, it is rolled into a coiler and then curled. However, when re crimping, the thickness is often presented as well as being accurate as some kind of error. This is no different from the edge is also easy to show flaws. Then curl again, trim the cutting head after straightening to ensure the thickness and accuracy of the rectangular tube.
