Marine crankshaft forging is the core component of Marine power system, its technical level and manufacturing quality have an important impact on the performance and safety of the ship. This paper will compare the technical level and gap of Marine crankshaft forgings at home and abroad, and provide reference for domestic enterprises to improve their technical level and catch up with the international advanced level.
Technical comparison at home and abroad
Manufacturing process: There are certain differences in the manufacturing process of Marine crankshaft forgings at home and abroad. Domestic enterprises usually adopt the traditional forging process, while foreign enterprises pay more attention to the application of advanced forging technology and equipment. For example, foreign enterprises generally use advanced heat treatment technology, precision machining technology, etc., to improve the performance and quality of crankshaft forgings.
Material selection: There are also differences in material selection for Marine crankshaft forgings at home and abroad. Domestic enterprises usually use ordinary steel as raw materials, while foreign enterprises pay more attention to the use of high-strength, high-corrosion resistance materials. For example, foreign enterprises generally use high-strength alloy steel, stainless steel and other materials to improve the strength and corrosion resistance of crankshaft forgings.
Quality control: There are also differences in the quality control of Marine crankshaft forgings at home and abroad. Domestic enterprises often have certain problems in quality control, such as unstable quality and batch inconsistency in the production process. Foreign enterprises pay more attention to quality control, through the establishment of a sound quality management system and testing means to ensure the quality stability and consistency of crankshaft forgings.
Gap analysis
Technical level gap: Compared with foreign advanced enterprises, there is still a certain gap in the technical level of domestic Marine crankshaft forging. Domestic enterprises in the manufacturing process, material selection, quality control and other aspects compared with foreign enterprises there is still a certain gap.
Innovation ability gap: Domestic enterprises in Marine crankshaft forging research and development and innovation are still insufficient. Foreign enterprises pay more attention to the research and application of new technologies and new materials, and constantly introduce new products and technologies to meet the changing market demand. However, domestic enterprises invest relatively little in research and development and innovation, and lack the ability and motivation of independent innovation.
Brand building gap: Compared with well-known foreign brands, there is still a gap in the brand building of domestic Marine crankshaft forgings. Foreign enterprises invest more in brand building, through advertising, marketing and other ways to improve brand awareness and influence. However, domestic enterprises have relatively little investment in brand building and lack of brand building awareness and strategy.
By comparing the technical level and gap of Marine crankshaft forgings at home and abroad, we can see that domestic enterprises still have shortcomings in technical level, innovation ability, brand building and so on. In order to improve the technical level and competitiveness of domestic enterprises, it is recommended to take the following measures:
Strengthen technological research and development and innovation: increase investment in scientific research, strengthen technological research and innovation, and improve the technical level of manufacturing processes and material selection. At the same time, enterprises are encouraged to strengthen cooperation with scientific research institutions, universities, etc., and promote the integrated development of production, learning and research.
Improve the level of quality control: establish a sound quality management system and testing means, strengthen the quality control and supervision in the production process, to ensure the stability and consistency of product quality. At the same time, strengthen quality awareness education and technical training to improve the quality awareness and skill level of employees.
Strengthen brand building: Increase investment in brand building, improve brand awareness and influence through advertising, marketing and other ways. At the same time, pay attention to the improvement of product quality and service, improve customer satisfaction and market competitiveness.
Introduction of advanced technology and equipment: actively introduce foreign advanced manufacturing technology and equipment to improve production efficiency and product quality. At the same time, we will strengthen cooperation and exchanges with international advanced enterprises and learn from their successful experiences and practices.
