In recent years, the proportion of seamless steel pipes in my country's steel production has been increasing. Due to its wide range of uses, higher requirements have been placed on its quality. Among them, the wall thickness deviation of seamless steel pipes is an important factor in its quality. One of the indicators. Wall thickness deviation will directly affect the range of use of seamless steel pipes. In the current increasingly fierce market competition, if a manufacturer cannot make a fuss about quality and produce high-quality seamless steel pipes, the loss of many market shares is inevitable. Avoided.
This article briefly elaborates on some of the issues involved.
In the actual production process, there are generally the following problems:
1. The deviation generated during the piercing process of the piercer.
2. Equipment manufacturing precision and structure
3. Installation and adjustment of equipment lines
4. Heating process of tube billet
5. Blank blanking
6. Influence of tool precision
7. Use automatic pipe rolling machine
