As an important part of ship structure, the quality control and traceability of Marine container forgings are of key significance to ensure the safety and reliability of ship structure. This paper will introduce the process quality control methods and traceability implementation measures of Marine container forgings, and discuss how to ensure the quality of forgings, and trace every link in the production process and material source.
introduction
Marine container forging is an important part to bear the load of the ship, and its process quality control and traceability can ensure the safety and reliability of the ship structure. Process quality control aims to ensure quality control in the manufacturing process of forgings, while traceability is achieved by documenting and tracing each production step and material source so that it can be traced and troubleshooting problems if needed.
Process quality control method of Marine container forgings
2.1 Develop a quality management system
Establish a quality management system suitable for Marine container forging manufacturing, clarify responsibilities and authority, and formulate corresponding quality management processes and norms. By means of system, document and process control, ensure the quality control of forging parts.
2.2 Strict material selection and inspection
According to the design requirements and specifications, select the materials that meet the requirements, and conduct material inspection and testing. It includes chemical composition analysis, mechanical properties testing and non-destructive testing to ensure that the quality of the material meets the requirements.
2.3 Control the processing process
Establish strict process parameters and operating procedures, monitor and control key process links. Including forging, heat treatment, machining, etc., through reasonable parameter setting and inspection methods, ensure that the geometric size, physical properties and surface quality of the forging meet the design requirements.
2.4 Conduct comprehensive inspection and testing
The use of modern non-destructive testing technology, such as ultrasonic, magnetic particle inspection, etc., to carry out comprehensive inspection and testing of forgings. At the same time, the physical performance test and corrosion resistance test are carried out to ensure the reliability and stability of the forgings in use.
In the production process, record and save the production information related to the forging, including forging parameters, heat treatment process, processing technology and test results. Ensure that the data of each link can be traced, and establish relevant documents and records.
3.2 Adopting the identification technology
Through marking technology, Marine container forgings are marked and coded. The marking content includes key information such as forging number, batch number, material grade, production date, etc., in order to trace its production process and material source.
3.3 Establish a traceability system
Establish a traceability system for Marine container forgings, record and manage all production and sales links. Including production records, quality certificates, inspection reports, procurement records, etc., to ensure that each batch of forging can be traced back to the original material source and production process.
The importance of forging quality control and traceability
Through scientific process quality control and traceability implementation measures, the quality stability and reliable performance of Marine container forgings can be ensured. In the face of quality problems or accidents, it can be traced back to the root of the problem in time, and the corresponding repair and improvement measures are taken to ensure the safe operation of the ship structure.
conclusion
Process quality control and traceability of Marine container forgings are very important for the safety and reliability of ship structures. Through the development of a quality management system, strict material selection and inspection, process control, comprehensive inspection and testing, as well as recording production information, the use of identification technology and the establishment of traceability system and other measures, it is possible to ensure that the quality of the forgings can be controlled, and trace its production process and material sources.
