hot-rolling Torque tube The continuous casting slab and blooming plate are used as raw materials, and then pass through the heating furnace, even when using high-pressure water to clean up the phosphorus on the surface, and then use the roughing mill, on the rectangular tube at the head and tail of the roughing mill, and then on the pipe, and then fed to the finishing mill for computer controlled fine 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.
