On the 20th of precision steel pipe production considerations on the 20th of precision cold drawn precision seamless steel pipe having inner and outer wall oxide layer, under high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring flattening without cracks, the surface has been made rust treatment, etc., mainly for mechanical structure, hydraulic equipment and car and motorcycle pneumatic or hydraulic components, such as cylinder or cylinders and so on. On the 20th production of cold drawn precision seamless precision steel industrial control including mold design, annealing, pickling, lubrication controlled conditions, and should do a good job in the capillary quality testing, refurbishing. On the 20th of cold drawn precision steel basic process is: hot capillary -> capillary inspection, grinding -> capillary pickling -> after capillary pickling recheck -> drawing -> finely drawn passes before straightening -> pickling, lubrication -> finely drawn -> finished before treatment -> storage. Automotive steel technical quality requirements due to the special nature of automotive materials, requirements with steel looks, light weight, with safe, stable and reliable. To ensure that the use of automotive steel aging requirements for steel material has good corrosion resistance, has a certain life of 20 # precision steel tubes, so based on the use of different parts of precision steel tubes, respectively, automotive steel materials, dimensional accuracy various aspects of mechanical properties, process performance and surface quality requirements are stringent. Some special steel products also have a corresponding requirement for wear, fatigue resistance, weldability. In many cases steel need to have good weldability, and have a good performance and reprocessing heat performance. Part of the final parts of the surface coating, pipe coating requirements, require bright automotive precision steel heat treatment is an advanced mechanical structure 20g precision steel pipe, according to the mode of production can be divided into three categories: one is a precision seamless ( pull or rolled); the other is a high-precision welded steel pipe (asked to go inside burr); then there is an internal deburring welded steel tube continues as cold (or final heat treatment) after the use of the car with precision steel tubes Automotive production process control, product particularity q345d its precision steel, with high technological content of products, using a variety of production needs. Some products need to set "Welding - Stubbs - rolled" The combination of production, in order to fully meet the requirements. For some of the need to develop an integrated production technology products, some domestic producers had some experimental studies, have accumulated some experience in production technology. However, the quality control needs in selected tube, pipe forming process, weld heat treatment, internal deburring technology, cold drawn (rolled) joint process, finished without oxidation (light) heat, high-precision (thin-walled) steel finishing, testing and other key technologies to achieve effective support, in order to fully ensure the technical quality precision steel production. gcr15 precision steel _ _ Weifang precision steel pipe industry by virtue virtue Liaocheng Industry Co., Ltd.
