Cold precision rolling pipe is widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, medium and low pressure boilers and other fields.
The main points of the production process of Cold precision rolling pipe are as follows:
1. The concentration of H2SO4 for pickling is 10%-15%, the temperature is 55-65℃, the ferrous content is ≤100g/l, and the pickling time is 30min.
2. It must be cleaned several times to wash the residue in the tube.
3. The manufacturer of the cold precision rolling pipe tells you that the first few passes of cold drawing use a conical outer die and a cylindrical inner die, and the first pass of the finished product uses an arcuate outer die and a conical inner die. All inner molds adopt "infiltrated metal inner mold".
4. The manufacturer of Cold precision rolling pipe tells you that the intermediate heat treatment adopts complete annealing, the annealing temperature is 850-880℃, and the time is 15min; the finished heat treatment adopts recrystallization annealing to remove residual stress, and the annealing temperature is 630-670℃, and the time is 10min.
5. Other processes perform normal processes.
The above is the production process of Cold precision rolling pipe, I hope to help you.
