The petrochemical industry has very high requirements for the safety, stability and long-term performance of equipment, and forging as a core component of equipment, its manufacturing technology innovation and development is particularly critical. Multidirectional forging technology, as an advanced metal forming process, is gradually being widely used in the manufacture of petrochemical forgings. This paper aims to discuss the research and application progress of multi-direction forging technology for petrochemical forgings, in order to provide reference for engineers and technicians in related fields.
Multi-direction forging technology refers to the forging of metal billets several times in different directions to achieve plastic deformation and microstructure refinement of metal. Compared with traditional one-way forging, multi-directional forging has the following advantages:
Refining grain: Through multi-directional forging, the grain of the metal can be effectively refined and the strength and toughness of the material can be improved.
Improve microstructure uniformity: Multi-directional forging helps to improve the internal microstructure uniformity of the metal, reducing segregation and defects.
Improve mechanical properties: The mechanical properties of forgings after multi-directional forging treatment are usually better than those of unidirectional forging.
Flexibility: Multi-directional forging can flexibly adjust the direction and number of forging according to different needs and the shape of the metal blank.
In the manufacture of petrochemical forgings, the multi-direction forging technology has made remarkable progress. It is reflected in the following aspects:
Material research: For different petrochemical materials, such as stainless steel, titanium alloy, etc., researchers are exploring suitable multi-directional forging process parameters to achieve the best microstructure and mechanical properties.
Process optimization: By optimizing the process parameters such as heating temperature, forging speed and holding time, a more efficient and environmentally friendly multi-directional forging process can be achieved. In addition, the introduction of advanced automation and intelligent technology can also further improve the accuracy and efficiency of multi-directional forging.
Equipment upgrade: In order to meet the needs of multi-directional forging technology, related equipment is also constantly upgraded and improved. For example, new forging presses, heating furnaces and control systems are developed to achieve precise control of the multi-directional forging process.
Quality inspection and control: In the process of multi-directional forging, strengthening quality inspection and control is the key to ensure the quality of forging. Through the introduction of non-destructive testing technology, metallographic inspection and other means, we can find and deal with possible problems in time, such as uneven organization, cracks and so on.
Taking a large petrochemical enterprise as an example, the enterprise uses multi-direction forging technology to produce a batch of high pressure reactor forgings. By optimizing process parameters and upgrading equipment, the company successfully achieved fine crystal strengthening and microstructure homogenization of forgings, significantly improving the strength and toughness of forgings. Compared with the traditional unidirectional forging, the mechanical properties of the forgings are improved by more than 20%. In addition, due to the adoption of advanced automation and intelligent technology, the production efficiency of the enterprise has also been greatly improved.
The research and application of multi-direction forging technology for petrochemical forgings are gradually deepening and improving. Through the continuous exploration and innovation of material research, process optimization, equipment upgrading and quality inspection and control, we can further improve the quality and performance stability of petrochemical forgings. In the future, with the continuous progress of science and technology and the improvement of green manufacturing requirements, we expect multi-directional forging technology to play a greater role in the manufacturing of petrochemical forgings and provide a strong guarantee for the sustainable development of the petrochemical industry.
