Design and research of high precision stainless steel pipe stainless steel pipe has many advantages, such as high strength, good corrosion resistance, strong impact resistance and so on, which makes it widely used in various fields of life. With the continuous improvement of automation, people have higher and higher requirements for the cutting quality of stainless steel pipe. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision, high automation high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, and it is also the inevitable trend of the further development of China's industry. Firstly, the intermittent cutting method of planetary bisymmetric eccentric installation can reduce the cutting deformation of stainless steel pipe and improve the cutting accuracy; Secondly, the tool of the intermittent stainless steel pipe cutting machine is eccentrically installed on the planetary gear to complete the rotation at the same time of revolution. Therefore, only one main motor can drive two tools to rotate.

For example, austenitic precipitated stainless steel can obtain high strength by precipitation hardening at ~ ℃ or ~ ℃ after solution treatment or cold working. That is, the supersaturated solid solution of some alloys is placed at room temperature or heated to more & amp; gt;& amp; gt;Austenitic stainless steel can be used to manufacture stainless spring, clock spring and steel wire rope in aviation structure after deformation strengthening. If welding is required after deformation, spot welding process and deformation can only be used to increase the tendency of stress corrosionStruer,Since the back is not filled with argon, its advantages are obvious, mainly for its simplicity and low cost, which is suitable for installation on the construction site. However, due to its structural characteristics, flux cored welding wire has high requirements for welders during operation, with fast wire feeding speed and high wire feeding accuracy. It is difficult to master. Welders should be specially trained and skilled before they can participate in welding in Yangba, Nanjing And foreign construction sites, we have successfully solved the problem that argon cannot be passed through the junction and repair port.Stainless steel has two classifications: one is divided into chromium stainless steel and chromium nickel stainless steel according to the characteristics of alloy elements; The other is divided into m stainless steel, f stainless steel, a stainless steel and A-F duplex stainless steel according to the microstructure of steel in normalized state.The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag, which can improve the yield of %, save energy and shorten the production cycle, so as to improve the yield of molten steel.
