With the rapid development of the global shipping industry, the demand for Marine diesel engines is increasing, and the quality and performance requirements of diesel forgings are becoming higher and higher. In order to meet the market demand and improve the quality and performance of diesel engine forgings, it is necessary to continuously improve the production process and strengthen the control of the production process. This paper will discuss the process improvement and practice of Marine diesel engine forging production.
The traditional production process of Marine diesel engine forgings mainly includes casting, machining and heat treatment. These processes have some shortcomings in the production process, such as low production efficiency, low material utilization rate, and unstable product quality. In addition, the production process of traditional technology will produce a lot of waste and pollutants, causing greater pollution to the environment.
In order to solve the shortcomings of traditional technology, it is necessary to explore new technology. In recent years, some advanced process technologies such as 3D printing, forging technology, laser cladding, etc. have been widely used in the production of Marine diesel engine forgings.
3D printing technology
3D printing is a rapid prototyping technology that is capable of producing parts with complex shapes. In the production of Marine diesel engine forgings, 3D printing technology can be used to manufacture some complex structural parts that are difficult to produce through traditional processes. In addition, through 3D printing technology can greatly shorten the production cycle and improve production efficiency. However, the cost of 3D printing technology is high, the variety of materials is limited, and it needs to be further developed and improved.
Forging technology
Forging technology is a method of making parts by applying external forces to deform metal billets. In the production of Marine diesel engine forgings, forging technology can improve the utilization rate of materials and the quality of products. In addition, the energy consumption and pollutant emission in the production process can be reduced through reasonable selection of forging process parameters. However, the equipment investment of forging technology is large, and the production process requires professional operators and technical support.
Laser cladding technology
Laser cladding technology is a method of melting metal powder and rapidly solidifying on the surface of the substrate to form a coating by means of a high energy laser beam. In the production of Marine diesel engine forgings, laser cladding technology can be used for surface strengthening and repair. The wear resistance, corrosion resistance and high temperature performance of the product can be improved by laser cladding technology. However, the cost of laser cladding technology is high, and the requirements for the substrate are also relatively high.
Taking a Marine diesel engine forging enterprise as an example, the enterprise successfully realizes the high efficiency and high quality production of Marine diesel engine forging by introducing advanced forging equipment and process technology. The specific measures include: optimizing the forging process parameters, improving the utilization rate of materials and product quality; Adopt new heat treatment technology to reduce energy consumption and pollutant emission; The introduction of automated production lines and intelligent testing equipment to improve production efficiency and product quality stability. Through the implementation of these measures, the company has realized the transformation and upgrading of Marine diesel engine forging production, and improved the market competitiveness of the company.
With the continuous progress of science and technology and the change of market demand, the production process of Marine diesel engine forging needs continuous improvement and innovation. The introduction of new process technology can improve product quality and performance, reduce production cost and environmental pollution. In the future, with the development of intelligent manufacturing technology, the production of Marine diesel engine forgings will be more automated, intelligent and green. At the same time, the development and application of new materials will also provide more possibilities for the production of Marine diesel engine forgings.
