I, smelting and continuous casting? Smelting and continuous casting of 16Mn precision steel pipe is one of the key steps in the manufacturing process. First, the raw materials are put into the electric furnace or blast furnace for smelting, by adding alloying elements and adjusting the chemical composition to obtain the required steel. Then, the molten steel is poured into a continuous casting machine for continuous casting to form billets. During this process, parameters such as the composition, temperature and oxygen content of the molten steel need to be controlled to ensure the quality and stability of the billet...?
Two, hot rolling? Hot rolling is one of the important links in the manufacturing process of 16Mn precision steel pipe. The continuous casting billet is heated to a high temperature and then rolled, and after several passes of rolling and cooling, the desired shape and size of the tube is gradually formed. In the hot rolling process, attention needs to be paid to controlling the rolling temperature and speed to ensure the shape and size accuracy of the pipe. At the same time, the hot rolling process also needs to straighten and cut the pipe to ensure the straightness and precision of the pipe.
Three, cold working and finishing? After hot rolling, 16Mn precision steel tube needs cold working and finishing to further improve the precision and surface quality of the tube. Through straightening, cutting, grinding, polishing and other process steps, the tube will be processed into the required length and precision requirements. In addition, non-destructive testing is required to ensure that the quality of the pipe meets the requirements. In this process, attention needs to be paid to controlling the process parameters of cold working and finishing to ensure the precision and surface quality of the tubes.
Four, quality inspection? Quality inspection is one of the important links to ensure the quality of 16Mn precision steel tube. By means of appearance testing, size testing, mechanical performance tests, etc., the pipe is subject to comprehensive quality inspection to ensure that the various indicators of the pipe meet the requirements. In this process, attention needs to be paid to controlling the accuracy and reliability of the inspection to ensure that the quality of the tubes meets the requirements of users.
Five, packaging and transportation? After the quality inspection of qualified 16Mn precision steel tubes need to be packaged and transported to protect the tubes from damage during transportation. General use of wooden frame or wooden box for packaging, and the use of steel bands or steel wire fixed to ensure the safety and stability of the pipe in the transportation process. In this process, attention needs to be paid to controlling the standardization and safety of packaging and transportation to ensure that the pipe is intact when it reaches the user.
Six, factory inspection? Before the 16Mn precision steel tubes leave the factory, it is necessary to carry out factory inspection to ensure that the products meet the relevant standards and user requirements. Factory inspection includes appearance testing, size testing, weight testing, non-destructive testing. Only through the factory inspection of the pipe can be officially delivered to the user. In this process, attention needs to be paid to controlling the standardization and accuracy of the factory inspection to ensure that the quality of the tubes meets the user's requirements.? The production process of 16Mn precision steel tubes includes several links, each of which has an important impact on the quality and performance of the tubes. Therefore, precision steel tube manufacturers need to strictly control the quality and technical parameters of each link in the production process to ensure that the precision and surface quality of the tubes meet user requirements. At the same time, it is also necessary to customize the production according to the actual demand to meet the needs of different areas.
