Precision cold drawn precision steel cold drawn pipe characteristic has the following characteristics: (1) High production efficiency: the traditional method of producing a 420 mm inner diameter, 12 m-long cylinder need 154 hours, produced by cold drawing only 4 min. (2) High rate: As boring rolling head and serves as a guide precision steel 40 * 6, in the cutting process precision steel tubes, blank tubes due to the self-weight deflection, resulting in rolling head and the boring tool easy road, resulting in waste . Authentic rate can only reach about 60%, while produced by cold drawing, genuine rate of 95%. (3) Metal utilization is high: the traditional method of making the cylinder bore, the metal utilization is only 50-70%. When drawing method for producing precision steel tubes by 58 * 6, not only to be cut into the metal iron at the end, but you can obtain a 30% elongation, the metal utilization up to 95%. (4) can improve the mechanical properties of the finished metal tubes: produced by drawing, the blank to obtain more than 30% of plastic deformation, due to the strength of the finished pipe leaving the work hardening of metal limits greatly improved. Usually in the finished tube inner strength limit by up to 60%. High-precision drawing tube is seamless hot-rolled steel, longitudinally welded pipes for the billets, after chemical treatment on a dedicated drawing machine, deformation theory by special drawing mold design, produce high-precision tubes. Dimensional accuracy of H10 ~ H8, the straightness of 0.35 ~ 0.5mm / m, the surface roughness of Ra1.6-0.4. Product quality, supply full, reasonable price, prompt delivery, in good faith, the principle of mutual benefit precision steel tubes 32 * 2, invites new and old customers come to visit us. I solemnly promise to you: to ensure the best quality at the lowest price, the best service, to acknowledge the new and old customers. The library does not have the specifications of advance telephone orders, ensure timely arrival.
