As a key component, port mechanical forgings play an important role in the performance and safety of ships. With the continuous development of the shipbuilding industry, the processing technology requirements for port mechanical forgings are also increasing. In order to meet the strict requirements of the ship industry, this paper will deeply discuss the processing technology of ship port mechanical forgings, including processing flow, key technology application cases and so on.
Processing flow
The processing process of mechanical forgings in ship ports includes the following main steps:
Raw material selection: According to the specific requirements of the forging, choose the appropriate material and specifications. In general, ship port machinery forgings need to choose high-strength, corrosion-resistant, fatigue-resistant metal materials.
Blank preparation: Pre-treatment of raw materials such as cutting and polishing, in order to carry out the next forging.
Forging: Through the high temperature and high pressure forging environment, the blank material is deformed, extruded and synthesized to obtain the desired shape and performance of the forging.
Heat treatment: Through the process of heating, insulation and cooling, the internal structure of the metal material is changed to achieve the purpose of improving the performance of the forging.
Machining: turning, milling, drilling and other processing operations for forgings to meet the assembly and use requirements of Marine machinery.
Quality inspection: The results of each processing link are tested to ensure that the quality of the forging meets the standards.
Key technology
Temperature control: During forging and heat treatment, precise control of heating and cooling temperatures is essential to ensure forging quality. By using intelligent temperature control system, real-time monitoring and accurate control of temperature can be achieved.
Forging process: According to the specific requirements of the forging, choose the appropriate forging process (such as free forging, die forging, etc.), optimize the forging parameters to improve the quality and production efficiency of the forging.
Quality control: Through the use of advanced non-destructive testing technology and statistical process control methods, the quality of forging is fully controlled. For example, non-destructive testing methods such as ultrasonic testing, X-ray testing, and magnetic particle testing can be used to ensure that internal defects of forgings are effectively controlled. At the same time, the statistical process control (SPC) method is used to monitor and adjust the key parameters in the production process to ensure the stability of the production process and the traceability of product quality.
When building a 10,000-ton cargo ship, a large shipbuilding enterprise needs a batch of high-quality port machinery forgings. The enterprise adopts advanced processing technology and strict quality control, and successfully manufactures high-quality forgings that meet the requirements.
First of all, in the selection of raw materials, the company chooses high-quality alloy steel as forging materials to ensure the high strength and corrosion resistance of the forgings. Secondly, in the forging process, the advanced free forging process is used to successfully manufacture forgings that meet the design requirements. In addition, in the heat treatment phase, the mechanical properties of the forgings are successfully improved by precisely controlling the heating and cooling temperatures. Finally, in the machining stage, the use of CNC machine tools and other efficient equipment to accurately process the forging, to ensure the dimensional accuracy and surface quality of the forging.
As a key component of ship, port mechanical forgings directly affect the performance and safety of ship. The processing flow, key technology and application cases of mechanical forgings in ship ports are introduced in detail in this paper. The quality and production efficiency of mechanical forgings in ship ports can be effectively improved by selecting suitable raw materials, accurately controlling temperature, rationally formulating forging process and strict quality control. The successful application of these technologies also provides a strong support for the future development of the shipbuilding industry.
With the continuous development of science and technology, the processing technology of ship port mechanical forgings will also continue to improve. In the future, the following trends can be foreseen:
Intelligent processing equipment: Through the introduction of advanced industrial Internet of Things and artificial intelligence technology, intelligent control and optimal scheduling of processing equipment can be achieved to improve production efficiency.
Green production process: The concept of environmental protection and sustainable development will run through the entire processing process, through the use of green energy and environmentally friendly materials to reduce environmental pollution in the production process.
Overall improvement of product quality: With the help of big data and cloud computing technology, quality data analysis and accurate control of the whole process are realized, thereby improving product quality and reliability.
Customized services: According to customer needs, provide customized forging products and solutions to meet customer’s individual needs.
In short, with the continuous development of science and technology, the processing technology of ship port mechanical forgings will continue to improve, providing a strong guarantee for the sustainable development of the ship industry.
