Marine diesel forgings are the key components in Marine power system, and the defects in the production process have an important impact on product quality and reliability. This paper will analyze the common defects in the forging process of Marine diesel engine, and put forward the corresponding preventive measures.
Common defects in the forging process of Marine diesel engine
crack
Crack is one of the common defects in the forging process of Marine diesel engine. The generation of cracks is mainly due to the internal stress concentration of the material, improper heat treatment or stress generated in the process of processing. The existence of cracks will seriously affect the strength and reliability of the product.
Surface defect
Surface defects of Marine diesel engine forging include pitting, oxide skin, decarburization and so on. These defects are mainly caused by factors such as improper material surface treatment, inaccurate heat treatment temperature control or friction generated during processing. Surface defects can affect the appearance and performance of the product.
Dimensional deviation
The size deviation of Marine diesel engine forgings is mainly caused by inaccurate size control or equipment accuracy problems during processing. Size deviation will affect the assembly and use performance of the product, and may even lead to safety accidents.
Measures to prevent defects in the forging process of Marine diesel engine
Strengthen material quality control
Selecting high-quality materials is the key to prevent defects in Marine diesel engine forging production. Enterprises should strengthen material quality inspection to ensure that the composition and mechanical properties of raw materials meet relevant standards and requirements. At the same time, reasonable heat treatment and processing of the material can reduce the internal stress concentration of the material.
Improve equipment accuracy and stability
Equipment accuracy and stability are the key factors to ensure the quality of Marine diesel engine forging. The enterprise should maintain and maintain the equipment regularly to ensure the normal operation of the equipment. At the same time, the use of advanced measuring and testing equipment, improve the accuracy and stability of the equipment, reduce the size deviation and surface defects.
Strengthen production process control
Production process control is an important link to prevent defects in Marine diesel engine forging production. Enterprises should develop a scientific and reasonable production process, clear the operating procedures and precautions of each process. Strengthen the quality control in the production process, discover and deal with problems in time, and ensure that the product quality meets the relevant standards and requirements.
Strengthen staff training and management
Employees are the valuable wealth of the enterprise, but also an important guarantee of product quality. Enterprises should strengthen the training of employees to improve their skill level and comprehensive quality. At the same time, a sound quality management system should be established to clarify the responsibilities and authority of personnel at all levels to ensure the effective implementation of product quality management.
The defects in the forging process of Marine diesel engine have an important influence on product quality and reliability. By strengthening material quality control, improving equipment accuracy and stability, strengthening production process control and strengthening staff training and management measures, can effectively prevent the defects in Marine diesel engine forging production process, improve product quality and reliability. This is of great significance to improve the competitiveness of the ship industry.
