The manufacturing process of precision seamless steel pipe generally includes the following main processes:
1. smelting: iron, carbon, alloy elements and other raw materials are smelted into molten steel by using smelting equipment such as electric furnace or converter.
2. Continuous casting: pouring molten steel into a continuous casting machine for solidification to form a billet.
3. Rolling: the billet is sent to a rolling mill to be rolled into a steel plate with a certain specification.
4. Heat treatment: the rolled steel plate is heat treated to improve its mechanical properties and corrosion resistance.
5. Straightening: Straighten the heat-treated steel plate to eliminate stress and improve straightness.
6. Cutting: cutting the straightened steel plate according to the required length.
7. Pickling: Put the cut steel plate into a pickling tank for pickling to remove the oxide layer and corrosion on the surface.
8. Polishing: Polishing the steel plate after pickling to obtain high-precision surface finish.
9. Quality inspection: Quality inspection of polished steel pipes, including size inspection and surface quality inspection.
10. packaging: packaging according to customer requirements, generally using vacuum packaging or nondestructive testing packaging.
In the manufacturing process of precision seamless steel pipe, each working procedure has its specific requirements and operating specifications, which need to be strictly controlled to ensure the quality and accuracy of the pipe. At the same time, various tests and tests are needed in the manufacturing process, such as chemical composition analysis, mechanical properties testing, nondestructive testing and so on. , to ensure that the performance indicators of the pipe meet the requirements.
Precision seamless steel pipe is widely used in aerospace, petrochemical industry, automobile manufacturing, medical equipment, power industry and many other fields. Precision seamless steel tube has become one of the ideal materials for many key components because of its high precision and high reliability.
In a word, precision seamless steel pipe is a kind of pipe with high precision, high strength and high corrosion resistance, and its manufacturing process adopts multiple processes to ensure the precision and quality of the pipe. Precision seamless steel pipe has become one of the indispensable materials in many fields because of its excellent performance and wide application fields.
