乘用车用管应用部位广,有许多特殊要求,属于高级机械结构用管。介绍了乘用车几种典型的常规要求钢管、制管工艺及生产工艺要点。详细介绍了乘用车特殊要求钢管的技术质量要求、再加工、生产工艺流程,以及应用冷拔、冷轧工艺和材质控制等生产满足不同要求的钢管产品。阐述了汽车用钢管开发的机遇与挑战,提出了汽车用钢管需要以其专业化生产和特有的高技术含量、高附加值来弥补规模化的不足。
Passenger car with a wide range of applications, there are many special requirements, belonging to the senior mechanical structure of the tube. Introduced the passenger car several typical conventional requirements of steel pipe, pipe technology and production process points. The technical requirements for the special requirements of passenger cars, the re-processing and production process, as well as the production of steel pipe products to meet the different requirements, such as cold drawing, cold rolling process and material control, are introduced in detail. The opportunities and challenges in the development of automobile steel pipes are expounded. It is pointed out that the steel pipes for automobiles need to make up for the shortage of scale with their specialized production and unique high-tech content and high added value.
