Production technology and quality control of Marine crankshaft forgings

Marine crankshaft forgings are the key components in the Marine power system, and their quality and performance are directly related to the performance and safety of the ship. Therefore, in the production process of Marine crankshaft forgings, the production process and quality control are very important. This paper will discuss the production process and quality control of Marine crankshaft forgings.

Production technology

Raw material preparation: The selection of high-quality raw materials is the basis for the production of high-quality Marine crankshaft forgings. Enterprises should select raw materials with good physical, chemical and mechanical properties and ensure that they meet relevant standards and requirements.
Heating and forging: Heating and forging are important links in the production process of Marine crankshaft forgings. Enterprises should use advanced heating equipment and processes to ensure that raw materials are heated at the appropriate temperature for subsequent forging operations. At the same time, the enterprise should adopt a reasonable forging process, and ensure that the shape and size of the crankshaft forging meet the design requirements by accurately controlling the temperature, pressure, speed and other parameters in the forging process.
Heat treatment: Heat treatment is an important means to improve the performance of Marine crankshaft forgings. Enterprises should choose the appropriate heat treatment process according to the material and performance requirements of crankshaft forgings, such as quenching, tempering, etc., in order to obtain the required mechanical and physical properties.
Surface treatment: Surface treatment is a key link to improve corrosion resistance and wear resistance of Marine crankshaft forgings. Enterprises should adopt advanced surface treatment technology, such as shot peening, carburizing, etc., to improve the surface quality of crankshaft forgings and improve their corrosion resistance and wear resistance.

Quality control

Quality management system: Enterprises should establish a sound quality management system, clarify the responsibilities and authority of each department and post, and ensure the effective implementation of quality management. At the same time, enterprises should develop strict quality standards and inspection procedures, and carry out strict quality control in all aspects of the production process.
Raw material inspection: The enterprise shall conduct strict inspection of raw materials to ensure that they meet relevant standards and requirements. For unqualified raw materials, they should be returned or processed in a timely manner to avoid affecting product quality.
Production process monitoring: enterprises should monitor all aspects of the production process in real time to ensure the stability of the production process and the consistency of product quality. For the problems and abnormal situations, timely measures should be taken to correct and improve.
Inspection and traceability of finished products: Enterprises should carry out strict inspection and testing of finished products to ensure that they meet relevant standards and requirements. At the same time, enterprises should establish a product traceability system to record and trace the production process of each product, so that they can quickly find the cause and take appropriate measures when there is a problem.
Continuous improvement: Enterprises should regularly evaluate the effect of quality management, find out existing problems and shortcomings, put forward improvement measures and put them into practice. Improve product quality and production efficiency through continuous improvement.

The production process and quality control of Marine crankshaft forgings are the key links to ensure product quality and performance. Enterprises should pay attention to raw material preparation, heating and forging, heat treatment, surface treatment and other production process optimization and control; At the same time, establish a sound quality management system, strengthen the quality control of raw material inspection, production process monitoring, finished product inspection and traceability and other links; And continue to improve the quality management effect, and constantly improve product quality and competitiveness. Only in this way can we meet the needs of customers, win market recognition and contribute to the sustainable development of the Marine industry.
